GRLWEAP Accessory Specifications for the Vulcan #2 and 30C Hammers

When WEAP86/87 was introduced, one of the major advances was the inclusion of a comprehensive hammer database. This has been continued and expanded in subsequent versions such as GRLWEAP 2003 and GRLWEAP 2010. One anomaly was that, although the Vulcan #2 and Vulcan 30C hammers were included in the database, the driving accessory information was not. This is probably because these hammers had become too small for many projects and their use was not common.

The #2 in particular, however, still finds its way on smaller projects such as Using a Vulcan #2 for Residential Piling, and so this post is intended to fill that gap.

The cushion area and thickness are as follows (from Vulcan Offshore Tip #20: Cushion Pot Dimensions):

• Cushion Area (Standard Cushion Pot): 82.5 in² (53,226 mm²)
• Cushion Thickness (Standard Cushion Pot): 7″ (178 mm)

As far as I know Vulcan never developed a capblock follower for the #2 or 30C.

The accessory weights (from Vulcan’s price lists in the early 1970’s) are as follows:

Pile Type	Accessory Weight, lb	Accessory Mass, kg
H-Beam Helmet, 10”, 12” and 14”	670	304
Z-Sheeting (such as PZ-27)	920	417
Concrete Piles 10”	920	417
Concrete Piles 12”	970	440
Concrete Piles 14”	970	440
Concrete Piles 16”	1080	490
Pipe Cap 8”-10”-12”	670	304
Pipe Cap 10”-12”-14”	690	313
Wood Piling	770	349

These, of course, assume the use of factory accessories; knockoffs are unfortunately common. (That’s also true for any Vulcan hammer.)
