Linerbolt removal tool improvements

A linerbolt removal tool, including:

• a) a housing;
• b) a moil supported for reciprocating movement along a hammer axis by a receptacle in the housing;
• c) an inertial body located within the housing;
• d) a gas charged accumulator extending from the inertial body in a rearward direction away from the moil;
• e) a piston moveable within the inertial body along the hammer axis between a striking position at which the piston strikes the moil and a retracted position remote from the moil at which a rear portion of the piston is retracted within the accumulator, whereby firing the piston from its retracted position to its striking position includes causing pressurised gas within the accumulator to accelerate the piston in a forward direction toward the moil, and
• f) cross pins traversing the receptacle for limiting movement of the moil, wherein when the moil impacts a linerbolt that is unable to absorb the striking energy imparted to the moil, forward movement of the moil is stopped by the cross pins, and wherein the cross pins are mounted in bushes formed from a resilient material.
