摘要： A reach type forklift truck is provided with a vehicle body and a reach leg extending forwards from the vehicle body. The reach leg has a guide rail fixedly attached thereto and provided with a vertical wall, a top flange and a bottom flange cooperating together to define a guide groove. A mast assembly with a base is supported on the reach leg and movable along the guide rail toward and away from the vehicle body. Front and rear support rollers are rotatably attached to the base of the mast assembly in a spaced apart relationship with each other and received in the guide groove of the guide rail. A front vertical clearance compensator is mounted to the mast base adjacent the front support roller for making contact with the underneath surface of the top flange of the guide rail, while a rear vertical clearance compensator is similarly provided adjacent the rear support roller for making contact with the top surface of the bottom flange of the guide rail. A lateral clearace compensator may be further employed to reduce the transverse jerking motion of the mast assembly.
