SW385 Swing Wheel Low Loader
The SW385 Swing Wheel Low Loader is based around the design of the SW300 Swing Wheel Low Loader, with the additional payload capacity derived from a larger float area and the use of larger tyres and hubs.

The Swing Wheel Low Loader is a rear-loading heavy equipment low loader, with a unique method of swinging the wheels aside to permit loading on a fixed, inbuilt ramp at the rear of the machine. The wheel action is particularly simple, involving merely a rotation of the “swing arms” supporting the wheels, about a single axis. This axis is inclined in two planes so as to produce the required motion of lifting the wheels off the ground, yet maintaining the wheels in a near-vertical plane for ease of tyre change out. The swing arms are positively located in place by a "twist-lock" arrangement driven by hydraulic cylinders.

During this swinging action, the low loader is secured by the park brakes of the prime mover and the jacks contacting the ground adjacent to the swing arms. At no time is the rear of the trailer unsecured – either the trailer brakes are fully locked on, or the jacks or underside of the ramp, are loaded against the ground.

This allows safe unloading of the machine on sloping ground, as there is no position where the rear of the trailer is not safely secured from unexpected motion, by either the jacks, or by the rear wheels, which remain locked by the park brakes throughout the swinging process.

It is possible to complete a load or unload cycle in about 10 minutes, with the swinging of the swing arms taking up the majority of this time. The speed of this motion has been deliberately set low to minimise any safety issues relating to moving these relatively large masses.
