Drop Hammer Attachment

Bobcat's new drop hammer attachment
smashes through concrete and asphalt
slabs up to 18-in. deep, providing an efficient
tool for site demolition. The company,
markets the attachment for use with skidsteer
loaders, compact track loaders and
all-wheel steer loaders in order to demolish
paved surfaces like driveways, sidewalks
and parking lots.

The hammer's main benefit is producing less wear on the attachment carrier by
working faster than hydraulic breakers and by employing a design that lets the ground absorb more of the impact rather than the machine and operator.

The key to the hammer's speed is the operator can keep the loader moving constantly, only pausing for the hammer to drop, which allows the loader to spread the hammer across larger amounts of flatwork than traditional hydraulic or pneumatic breakers. The hammer hits at a rate of 20 blows-per-minute, allowing a three-second repositioning sequence between each drop.

The hammer uses a 1,140-lb. weight, lifted by a chain and drive motor. The hammer weighs 1,950 lbs. After detachment from a loader, the hammer can stand upright without support.

Excavating Rig

Hitachi Mining, based in Tokyo, and with

model, offering twice as much cab space,
giving the operator more room and better
visibility.

It also offers wide-angle cameras that feed into a color monitor, giving the operator a split-screen view around the machine.
