Abstract
Side shift backhoe clamped by two vertical acting and one horizontal clamp. Restrictors allow operation of vertical clamps prior to horizontal to prevent loading of slide rail. Vertical clamp actuators are secured in casting by L-shaped slots which allow actuator to be secured without bolts and allow vertical movement of actuators. Hook on casting takes longitudinal loads and resolves them partially to vertical loads.
