The secondary block (the block with the single hook, to the right) was better suited for this task, and this fact was a driving force in the development of Vulcan's 560 hammer.https://vulcanhammer.info/wp-content/uploads/2019/11/santa-fe-560-no-packing.jpgSanta-Fe-560-No-Packinghttps://vulcanhammer.info/wp-content/uploads/2019/11/d11006-1.jpgD11006-1https://vulcanhammer.info/wp-content/uploads/2019/11/d11268-2a.jpgD11268-2ahttps://vulcanhammer.info/wp-content/uploads/2019/11/d11006-2.jpgD11006-2https://vulcanhammer.info/wp-content/uploads/2019/11/d13000-1.jpgD13000-1https://vulcanhammer.info/wp-content/uploads/2019/11/d11268-1a.jpgD11268-1ahttps://vulcanhammer.info/wp-content/uploads/2019/11/d13000-2.jpgD13000-2https://vulcanhammer.info/wp-content/uploads/2019/11/d13002-1.jpgD13002-12024-12-28T21:08:10+00:00monthlyhttps://vulcanhammer.info/2024/12/26/comments-on-prefabricated-and-prestressed-bio-concrete-piles-case-study-in-north-jakarta/2024-12-26T21:06:14+00:00monthlyhttps://vulcanhammer.info/2017/06/29/vulcan-onshore-tip-51-sheet-pile-designations/2024-12-25T23:28:47+00:00monthlyhttps://vulcanhammer.info/2023/08/07/sheet-pile-profiles-for-zp-32-zp-38-mz-32-mz-38-mz-27-and-zp-27-sheeting/https://vulcanhammer.info/wp-content/uploads/2023/08/vulcan-data-manual_page_08.pngvulcan-data-manual_page_082024-12-25T23:25:47+00:00monthlyhttps://vulcanhammer.info/2023/08/09/historical-sheet-pile-profiles-for-shallow-arch-sheeting/2024-12-25T23:25:14+00:00monthlyhttps://vulcanhammer.info/2023/08/10/historical-deep-arch-sheeting-profiles/https://vulcanhammer.info/wp-content/uploads/2023/08/vulcan-data-manual_page_06.pngvulcan-data-manual_page_062024-12-25T23:24:17+00:00monthlyhttps://vulcanhammer.info/2023/08/11/historical-flat-sheet-profiles/https://vulcanhammer.info/wp-content/uploads/2023/08/vulcan-data-manual_page_07.pngvulcan-data-manual_page_072024-12-25T23:23:44+00:00monthlyhttps://vulcanhammer.info/2023/08/12/historical-sheet-pile-sections-for-national-steel-corporation/https://vulcanhammer.info/wp-content/uploads/2023/08/vulcan-data-manual_page_09.pngvulcan-data-manual_page_092024-12-25T23:22:47+00:00monthlyhttps://vulcanhammer.info/2019/05/09/vulcan-3100-hammer-specifications-and-information/https://vulcanhammer.info/wp-content/uploads/2019/05/3100-nt-cta.jpg3100-NT-CTAIn spite of the success of the 3100 assembly in the customer's yard, not all of these hammers were assembled in the field.

Virtually all offshore piles were driven on a batter. Since the weld integrity of the add-on had to be of good quality, a stable connection between the add-on and the pile segment already driven was a must. This common solution used a pipe inside of the pipe being driven with a tapered cut at the bottom for easy stabbing.

The leaders were spray painted, which made the "Special Products Division" (the plant's designation) unpopular with UPS employees when their cars had the misfortune of being downwind during painting.2023-09-15T20:20:40+00:00monthlyhttps://vulcanhammer.info/2023/09/05/basic-data-of-production-experience-and-technical-and-economic-indicators-of-vibration-immersion-of-metal-sheet-pile/https://vulcanhammer.info/wp-content/uploads/2023/09/sl-figure-86.jpgsl-figure-86https://vulcanhammer.info/wp-content/uploads/2023/09/sl-figure-85.jpgsl-figure-852023-09-05T17:44:30+00:00monthlyhttps://vulcanhammer.info/2017/06/29/vulcan-onshore-tip-60-hammer-warranty-and-safety/https://vulcanhammer.info/wp-content/uploads/2017/06/ontip60.pngontip602023-08-23T14:09:02+00:00monthlyhttps://vulcanhammer.info/2023/09/04/features-of-the-technology-of-vibratory-immersion-of-sheet-piling-using-piling-headframes/https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-84.jpgsl-figure-84https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-83-en.pngsl-figure-83-en2023-08-23T11:57:57+00:00monthlyhttps://vulcanhammer.info/2023/08/28/production-of-works-for-immersion-of-metal-sheet-piles-using-jib-cranes/https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-82.pngsl-figure-82https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-81.pngsl-figure-81https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-80.jpgsl-figure-80https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-79.jpgsl-figure-79https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-78.jpgsl-figure-78https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-77.jpgsl-figure-77https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-76.jpgsl-figure-76https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-75.jpgsl-figure-75https://vulcanhammer.info/wp-content/uploads/2023/08/sl-figure-74-1.pngsl-figure-74-12023-08-19T20:45:56+00:00monthlyhttps://vulcanhammer.info/2023/08/21/manufacture-of-works-on-vibration-immersion-and-extraction-of-metal-sheet-piling-general-information/2023-08-16T20:14:26+00:00monthlyhttps://vulcanhammer.info/2023/08/15/historical-belval-sheeting-sections/2023-08-14T14:56:08+00:00monthlyhttps://vulcanhammer.info/2023/08/14/historical-frodingham-sheeting-sections/2023-08-14T01:55:18+00:00monthlyhttps://vulcanhammer.info/2023/08/13/historical-larssen-sheeting-sections/2023-08-12T22:19:13+00:00monthlyhttps://vulcanhammer.info/2021/09/22/sheet-pile-templates/2023-08-11T16:50:01+00:00monthlyhttps://vulcanhammer.info/2023/08/05/comments-on-using-the-impulse-response-pile-data-for-soil-characterization/2023-08-05T20:22:42+00:00monthlyhttps://vulcanhammer.info/2023/08/03/comments-on-fictitious-soil-pile-model-for-dynamic-analysis-of-pipe-piles-under-high-strain-conditions-vulcanhammer-net/2023-08-03T23:58:38+00:00monthlyhttps://vulcanhammer.info/2017/08/18/california-series-pile-hammers/https://vulcanhammer.info/wp-content/uploads/2017/08/california-e-f-parts-diagram.jpgCalifornia E F Parts DiagramParts diagram for the California "E" and "F" hammers.

The analysis of statics was well established in engineering education and practice by the last half of the nineteenth century and is employed in this case on pile hammer leaders. In this case the leaders are being analysed using a truss type of model and a graphical solution to the static equilibrium equations. Truss models are, strictly speaking, inapplicable to leaders, because the joints are not pinned, but can be a reasonable approximation. The labour of calculations pushed the industry towards a more "section modulus" approach (which has limitations of its own) but the best solution to date has been finite element analysis, which will be discussed below.https://vulcanhammer.info/wp-content/uploads/2017/06/1453-gw-strain-sheet.png1453-GW-Strain-SheetAnother strain sheet, this time for the dipper friction, done by George Warrington and dated 22 April 1893.https://vulcanhammer.info/wp-content/uploads/2017/06/1011.png1011A "strain sheet" for a truss design for the #3 dredge dated 20 February 1889.

The "front door" of the hammer both protected the fluid valve from being hit (the MKT and Nilens hammers did not) and allowed for easy access. Vulcan wags, however, would say that easy access was necessary with a fluid valve, which was a long-standing Vulcan peeve.https://vulcanhammer.info/wp-content/uploads/2017/08/horn-hc-10-front-view-cover-closed.jpgHorn-HC-10-Front-View-Cover-ClosedHC-10 Airmizer hammer, with a 10,000 lb. ram.https://vulcanhammer.info/wp-content/uploads/2017/08/horn-hc-8-front-view-2.jpgHorn-HC-8-Front-View-2An angled view of the HC-8 hammer.https://vulcanhammer.info/wp-content/uploads/2017/08/horn-hc-8-front-view.jpgHorn-HC-8-Front-ViewFront view of the HC-8 hammer, which had a 8,000 lb. ram.https://vulcanhammer.info/wp-content/uploads/2017/08/horn-hc-6-front-view.jpgHorn-HC-6-Front-ViewHC-6 hammer, front view. It had a 6,000 lb. ram, and, unlike many of the other Airmizer hammers, was held together with cables rather than tie rods. Vulcan's aversion for tie rods was consistent; addition of cables was probably a major improvement for the hammer.https://vulcanhammer.info/wp-content/uploads/2017/08/horn-hc-8-back-view.jpgHorn-HC-8-Back-ViewBack view of the HC-8 hammer.https://vulcanhammer.info/wp-content/uploads/2017/08/horn-construction-fixed-leaders.jpgHorn Construction Fixed LeadersA fixed leader pile driving rig by Horn Construction, Long Island, NY, during the 1960's. Note that the air compressor (sporting Horn and Vulcan's Supertherm) is mounted on the back.

An attempt to look to the future and address these difficulties was the 5250 hammer, with a 250 kip ram and 1250 ft-kip rated striking energy. The hammer came just as things started to slide downward in the oil industry, and Vulcan never produced another hammer in this size range.https://vulcanhammer.info/wp-content/uploads/2017/08/d11652.jpgD116522019-11-24T22:01:11+00:00monthlyhttps://vulcanhammer.info/2017/09/15/vertical-drains-sand-and-wick/https://vulcanhammer.info/wp-content/uploads/2017/09/d100179.jpgD100179A Vulcan drawing showing the components of the sand drain system.https://vulcanhammer.info/wp-content/uploads/2017/09/4600-wick-drain-6.jpg4600 Wick Drain 62019-11-24T21:58:14+00:00monthlyhttps://vulcanhammer.info/2019/11/17/vulcan-5110-specifications-and-information/https://vulcanhammer.info/wp-content/uploads/2019/11/5110spec-2.png5110SPEC-22019-11-17T16:19:44+00:00monthlyhttps://vulcanhammer.info/2019/11/17/vulcan-5100-specifications-and-information/https://vulcanhammer.info/wp-content/uploads/2019/11/d11622-1-2.jpgD11622-1-2https://vulcanhammer.info/wp-content/uploads/2019/11/d11622-1-3.jpgD11622-1-3https://vulcanhammer.info/wp-content/uploads/2019/11/d11622-1-1.jpgD11622-1-12019-11-17T14:25:48+00:00monthlyhttps://vulcanhammer.info/2019/11/16/vulcan-540-hammer-specifications-and-information/https://vulcanhammer.info/wp-content/uploads/2019/11/540-nt-cta.jpg540-NT-CTAVulcan 540 at the plant in Chattanooga.

The cable arrangement is similar to the one Vulcan adopted on the offshore hammers. Although it required the use of 26" jaws, it was surely superior to the "pocket" cables Vulcan adopted about ten years later.https://vulcanhammer.info/wp-content/uploads/2019/01/d10357-c.jpgd10357-chttps://vulcanhammer.info/wp-content/uploads/2019/01/d10250-c.jpgd10250-chttps://vulcanhammer.info/wp-content/uploads/2019/01/2860-c.jpg2860-chttps://vulcanhammer.info/wp-content/uploads/2017/06/vulcansheet.jpgvulcansheetVulcan 50C, driving sheet piling. Vulcan hammers weren't known to be sheet pile specialists but, as these photos show, they got the job done anyway. As was the case before, an "offshore" type leader was used, where a stub leader was hung from a crane and lowered with the hammer. This is good when the pile is supported at the ground, either by a template or in this case other sheet piles. https://vulcanhammer.info/wp-content/uploads/2017/06/vulcan50c.jpgvulcan50CVulcan 50C hammer, installing sheet piling, Chicago, 1974. Note the yellow Decelflo muffler on top of the hammer; this was one of the first uses of the exhaust muffler. https://vulcanhammer.info/wp-content/uploads/2017/06/dwpb1361.jpgDWPB1361A concept for the muffler: mount it directly on the back of the hammer, using a bracket integral to the hammer. A special cylinder head would transmit the air from the exhaust to the muffler. Unfortunately the Decelflo program didn’t get far enough for Vulcan to try this concept.https://vulcanhammer.info/wp-content/uploads/2017/06/50cswingingleadshudsonoh.jpg50CSwingingLeadsHudsonOHVulcan 50C driving piles on a batter using swinging leaders, Hudson, OH.

Vulcan was relatively late in the life of the product line in putting cables on the differential-acting hammers, and when it did the "pockets" (which you can see on either side of the cylinder just below the steam chest) made it impossible to jack the cables. Both Raymond and Pile Hammer Equipment had better methods of cabling the Super-Vulcan hammers.https://vulcanhammer.info/wp-content/uploads/2019/01/vulcan80c.jpegvulcan80cVulcan 80C hammer driving 55' long 12" concrete piles for the Bay Area Municipal Utilities Sewage Treatment Plant, Oakland, CA.

This hammer was an 80C with a light ram. The operating pressure was now at 95 psig, well within the reach of available air compressors. The main disadvantage of this is that it requires 26" jaws; how much of a disadvantage that is depends upon the contractor.https://vulcanhammer.info/wp-content/uploads/2019/01/65c-general-arrangement.png65c general arrangementAn early concept of the 65C hammer. The idea here is that the large bore is increased in size, which would have kept the pressure at 120 psig. Vulcan opted to keep the cylinder the same as the 50C, which forced the operating pressure upwards to 150 psig. That in turn required adding a false head to compensate for the additional upward force on the frame. The false head made the 65C expensive to produce, and the high pressure put it out of reach for many air compressors.2019-01-21T02:40:50+00:00monthlyhttps://vulcanhammer.info/2019/01/07/vulcan-4-hammer-specifications-and-information/https://vulcanhammer.info/wp-content/uploads/2019/01/4-sn986-slide-bar-variations.jpg#4 sn986 slide bar variationshttps://vulcanhammer.info/wp-content/uploads/2019/01/2920a.jpg2920a2019-01-08T03:45:06+00:00monthlyhttps://vulcanhammer.info/2019/01/05/concrete-pile-cutter-sp-88-operations-manual/https://vulcanhammer.info/wp-content/uploads/2019/01/so300-nc-job-e1546742403839.jpegso300 nc jobhttps://vulcanhammer.info/wp-content/uploads/2019/01/pilebver-e1546742299619.jpegpilebver2019-01-06T02:40:08+00:00monthlyhttps://vulcanhammer.info/2017/09/16/new-method-and-device-for-breaking-and-removal-of-protruding-pile-parts/https://vulcanhammer.info/wp-content/uploads/2017/09/concrete-pile-cutter.jpgConcrete Pile CutterConcrete Pile Cutter SP-88 on its first (and last) job in the U.S. in North Carolina, early 1990's.2019-01-06T02:25:08+00:00monthlyhttps://vulcanhammer.info/2018/12/29/hydraulic-vibratory-hammer-the-foster-4200/https://vulcanhammer.info/wp-content/uploads/2018/12/Foster-4200-Exciter-1.jpegFoster-4200-Exciterhttps://vulcanhammer.info/wp-content/uploads/2018/12/4200_12_Page_40.png4200_1&2_Page_40The hydraulic schematic of the system. Most of the fluid is stored in the reservoir (1) until drawn into the main pump (6) or the clamp pump (6e). The fluid driving the motors runs through the supply quick disconnects (12) to the hammer, and returns through the return quick disconnects (13). The oil then goes through the oil cooler (15) before returning to the reservoir (1). The clamp pressure, alternating between the two hoses (10) and (10a), is controlled by a directional control valve (7). The case drain line (19) goes directly to the reservoir (1) to minimise back pressure.https://vulcanhammer.info/wp-content/uploads/2018/12/4200_12_Page_47.png4200_1&2_Page_47The hose layout for the 4200 exciter.

The diesel engine is the prime mover of the system. The pump drive transmits torque to the "pump stack," which includes the pressure-compensated pump for the motor and the clamp pump. The reservoir stores and cools the oil between cycles in the hydraulic system.https://vulcanhammer.info/wp-content/uploads/2018/12/foster-pp-outside.jpegfoster pp outsideAn outside shot of the power pack. The control panel is for an electric-over-hydraulic system which Vulcan began using when it built its own power packs (HPSI units were air-over-hydraulic.) The remote control pendant allows the unit to be operated from the crane or wherever is most convenient. The hoses come from the exciter and can be 50'-150' long for this size of unit. The quick disconnects allow easy connection and disconnection of the hoses from the power pack, but should be avoided when possible because they contribute to frictional losses in the hydraulic fluid.https://vulcanhammer.info/wp-content/uploads/2018/12/Piston-Hydraulic-Pumps-1.jpgPiston-Hydraulic-Pumps-1https://vulcanhammer.info/wp-content/uploads/2018/12/Piston-Hydraulic-Pumps.jpgPiston-Hydraulic-Pumps2020-08-29T08:04:10+00:00monthlyhttps://vulcanhammer.info/2018/12/12/vulcan-012-hammer-specifications-and-information/https://vulcanhammer.info/wp-content/uploads/2018/12/d62v10101.jpgD62V10102018-12-31T23:03:00+00:00monthlyhttps://vulcanhammer.info/2018/12/28/russian-hydraulic-demolition-hammers/https://vulcanhammer.info/wp-content/uploads/2018/12/Russian-9-kJ-Demolition-Hammer-on-Excavator.jpgRussian-9-kJ-Demolition-Hammer-on-Excavatorhttps://vulcanhammer.info/wp-content/uploads/2018/12/HYDFIG6.jpegHYDFIG6Figure 6 Hydraulic Schematic of Demolition Hammer 1) Check Valve 2) Working Cylinder 3) Control Valve 4) Check Valve 5) Fluid Springhttps://vulcanhammer.info/wp-content/uploads/2018/12/HYDFIG5.jpegHYDFIG5Figure 5 Operating Principle of Hydraulic Hammer -- End of Upward Acceleration 1) Impact Tool 2) Body 3) Ram 4) Rod 5) Rod End Cavity 6) Piston 7) Check Valve 8) Drain Port 9) Head End Cavity 10) Duct 11) Control Valve 12) Accumulator Piston 13) Drain Line 14) Pump 15) Fluid Spring Cavity 17) Springhttps://vulcanhammer.info/wp-content/uploads/2018/12/HYDFIG4.jpegHYDFIG4Figure 4 Operating Principle of Hydraulic Hammer -- Beginning of Cycle, Ram in Bottom Position 1) Impact Tool 2) Body 3) Ram 4) Rod 5) Rod End Cavity 6) Piston 7) Check Valve 8) Drain Port 9) Head End Cavity 10) Duct 11) Control Valve 12) Accumulator Piston 13) Drain Line 14) Pump 15) Fluid Spring Cavity 17) Springhttps://vulcanhammer.info/wp-content/uploads/2018/12/HYDFIG3.jpegHYDFIG3Figure 3 Plug for Air Outlet from Fluid Spring 1) Working Cylinder Casing 2) Plug 3) Sealing Ring 4) Air Outlet Plug 5) Fluid Spring Cavityhttps://vulcanhammer.info/wp-content/uploads/2018/12/HYDFIG2.jpegHYDFIG2Figure 2 Working Cylinder 1) Casing 2) Sleeve 3) Accumulator Bushing 4) Accumulator Rod 5) Piston 6) Check Valve 7) Lid 8) Check Valve 9) Piston Rodhttps://vulcanhammer.info/wp-content/uploads/2018/12/HYDFIG1.jpegHYDFIG1Figure 1 Hydraulic Hammer 1) Working Cylinder 2) Guide Pipe 3) Ram 4) Interchangeable Tool 5) Interchangeable Tool Guide (axle box)2018-12-29T03:11:55+00:00monthlyhttps://vulcanhammer.info/2017/07/12/chattanooga-plant-expansion/https://vulcanhammer.info/wp-content/uploads/2017/07/Chattanooga-Plant.jpgChattanooga Plant2018-12-28T18:14:37+00:00monthlyhttps://vulcanhammer.info/2018/11/22/vulcan-1-hammer-specifications-and-information/https://vulcanhammer.info/wp-content/uploads/2018/11/327-north-bell-1.jpeg327-north-bell-1The Vulcan #1 hammer in the place where many were made: the 327 North Bell Avenue facility in Chicago.

This version sports tapered fittings on the bottom, an adaptation from Raymond. Another Raymond adaptation were the cables to the cylinder head. Later onshore hammers used a straight "button" type fitting on the bottom and ran the cables to just above the valve chest on the cylinder.https://vulcanhammer.info/wp-content/uploads/2018/11/d11243.jpgD11243A #1 general arrangement featuring a Vari-Cycle (trip shifter.)
