Allied Hammerhead II Model HB 550

Mon November 20, 2006 - National Edition

The Allied Hammerhead II Model HB 550 is a self-contained hydraulic concrete slab buster designed to demolish concrete flatwork. The concrete is rubblized at a 45-degree angle from the point of impact.

This concrete flatwork includes floors, driveways, bridge decks and roadways up to 12 in. (30.5 cm) thick. Using three moving parts, the Hammerhead II offers a design that lowers maintenance and repair costs, according to the manufacturer.

Hammerhead II will operate vertically or horizontally on concrete surfaces. An internal hydraulic cylinder and valve system compresses a heavy compression spring set. This spring set “loads” the system with 3,350 psi (231 bar) of hydraulic pressure.

On the return stroke of the cylinder, Hammerhead II releases the trigger mechanism. This mechanism causes the 4-in. (10.2 cm) impact bar weighing 388 lbs. (176 kg) to “fire” at the concrete with up to a 4,000-ft.-lb. energy class impact force.

The Allied Hammerhead II Model HB 550 is a 1,130-lb. (513 kg) hydraulic concrete slab buster that mounts on a 5,000 to 9,000-lb. (2,268 to 4,083 kg) skid steer, 7,000 to 15,000-lb. (3,175 to 6,804 kg) mini excavator or 9,000 to 16,500-lb. (4,083 to 7,484 kg) loader/backhoe.

According to the manufacturer, the Model HB 550 concrete slab buster features:

• A single blow rubblizes concrete reducing labor intensive jobs to fast demolition and clean-up

• Demolishes concrete flatwork up to 10 times faster

• No troublesome seals or backpressure to damage the hydraulic system

• No nitrogen gas to check or charge as nitrogen gas is not required for power
