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.

Abstract: A wear member includes a front end and a rearward end, the rearward end having a cavity formed therein. The cavity may include a forward portion, a rear portion, and an intermediate portion. The forward portion may be disposed toward the front end and the rear portion may be disposed toward the rearward end. Each of the rear portion and the forward portion may include at least four surfaces. Each of the at least four surfaces of the rear portion may converge toward a longitudinal axis of the wear member at a first converging angle, and each of the at least four surfaces of the forward portion may converge toward the longitudinal axis of the wear member at a second converging angle.

Abstract: A bollard assembly is formed from a bollard that resides in a tubular socket. The socket has an internal core that is separated from the tube walls by annular recess. The lower end of the bollard is received within the recess. Lifting elements inside the bollard engage the upper surface of the core, and are internally biased in favor of extension. A locking system prevents extension of the lifting elements. When the locking system is unlocked, the pressure of the lifting elements against the core causes the bollard to rise out of and slightly above the socket, without external assistance. Once raised, the bollard may easily be removed from the site of the socket.
