The Model 70C hydraulic impact hammer from Allied Construction Products is a 640-pound hammer designed to mount quickly on a mini-excavator. The unit features straight hydraulic hose fittings for leak-free connections; tool bushings slip-fit to facilitate removal and conversion brackets to allow the hammer to be changed quickly from loader backhoes to skid-steers. A bolt-on top-mounting bracket facilitates attachment to excavators using quick couplers.
