Robbins 34RH C

Robbins 34RH C

A low profile small diameter raise drill, ideal for slot raises, back filling and narrow vein mining applications. It can be used for conventional raiseboring, downreaming as well as upward boxhole boring. This makes the Robbins 34RH C the most versatile raise drill on the market. The standard frame enables a 720 mm reamer to pass the work table.

功能和特点
● Remote controlled hydraulic worktable enables the reamer and stabilizers to pass through the mainframe.
● The single hydraulic drive power pack features variable speed and excellent torque limiting control
● Telescopic thrust cylinders provide high thrust in low profile
