For many years Vulcan hammers have used woven packing to seal around the piston rod. Although this type of packing has performed well, packing with longer life would obviously be better for hammer users. Vulcan now offers a packing that uses a chevron type packing, similar to rod packing used in hydraulic cylinders. This packing … Continue reading Vulcan Onshore Tip #70: Hydraulic Cylinder Type Packing Upgrade (#1 and #0 Hammers)

Never use an air hose to carry steam! Steam will melt the air hose. Take off … Continue reading Vulcan Onshore Tip #64: Proper Hose Connection
Operation of Pile Hammers and Pile Extractors on compressed air frequently presents problems of ice accumulation in valve assemblies and air passage ports. Icing is a function of temperature and humidity causing erratic equipment operation as, strange as it may seem, icing conditions occur at 85° as well as 32° if conditions are right. There … Continue reading Vulcan Onshore Tip #63: Icing Conditions
While Pile Hammers are not unduly difficult to handle there are some basic precautions to be observed as well as some basic Do's and Don'ts. Note: Hammer handing as "not unduly difficult" only applies to specialists in material handing.
