The Loadquip 150t Hinge Hitch Low Loader (HH150) is a rear loading heavy equipment low loader, with a unique method of pivoting the hitch to permit loading on a fixed, inbuilt ramp at the rear of the machine. The hitch action is particularly simple. When actuated, the hinge hitch arrangement allows the front of the deck to be raised. The deck pivots about the low loader wheels, in turn lowering the rear of the deck to the ground. The hinge hitch is actuated by hydraulic cylinders and is positively located in place by locking pins driven by hydraulic cylinders.
During this pivoting action, the low loader is secured by the park brakes of the prime mover and trailer. This means the trailer will be safely secured from unexpected motion during the entire loading and unloading cycle. All wheels are braked with oil cooled disc brakes, fully integrated with the prime mover braking system. It is possible to complete a load or unload cycle in about 5 minutes, with the majority of time being for the manoeuvring of plant onto or off the deck of the low loader trailer.
For loading and unloading, the tilting motion is controlled via a wireless remote control unit. By allowing the operator to operate the tilt from within the cab of the payload item, there is never a need for the operator to walk on the low loader deck when tilted. The tow unit shown is a Caterpillar 785, however a Caterpillar 777 would generally be suitable for the 150t payload.
