The four models in the new in-Series hammers use a massive, trapezoidal tool, which is non-breakable, even when operators pry with it, says Allied. The hammers use only a single tool bushing made of a composite, wear-resistant material that eliminates the need for greasing. The hammer design also eliminates tie rods and tie bolts normally required to retain hammer components. A nitrogen accumulator is used, but only as a shock-absorbing device to cushion the carrier's hydraulics from pressure spikes. Designed for use on skid-steer loaders (mini and standard), compact excavators and backhoe-loaders, the new hammer models range in weight from 152 to 453 pounds.
