Abstract
A wear assembly such as an adapter for a cable shovel having a Whisler-style lip has two legs extending over the lip, and a hole in the legs arranged to align with a hole in the lip. A locking member is inserted in the hole, and hooked around a pivot surface in the lower leg. An actuator is inserted into the hole in the upper leg, and engages with t top end of the locking member. Movement of the actuator causes pivoting of the locking member, and results in the locking member bearing against the lip hole in order to lock the wear assembly in position.
