Front loader vehicle with telescoping boom |
摘要 |
A truck vehicle carried boom system for lifting, transporting, and depositing a load of particulate material such as powder, granules or seeds into storage bins in material dispensing aircraft, including a telescoping boom structure pivotally mounted on support structure which in turn is rigidly secured to the vehicle frame. The boom includes provision for removable carrying a hopper form of load bag. An extensible piston-cylinder hydraulic motor is utilized to obtain various pivotal positions of the boom. The boom telescope disposition is maintained by a mechanical safety pin. The boom is extended and retracted by inertial forces generated by vehicle manipulation. As an auxiliary device a boom safety bar, hydraulically operated is secured to a side portion of the truck bumper structure to provide a safety block when the boom is in the aircraft loading position.
