SIMON ENGINEERING of Dudley has developed a stabilising system for mobile hydraulic platforms. The Simjax is claimed to be lighter, less expensive, and easier and quicker to use than conventional hydraulic jacking Systems.
It was designed for use with Simon's new RCA range of medium-sized articulated boom, hydraulic access platforms, but it can be fitted to other units where the turntable is mounted over the rear-axle.
The Simjax's two stabiliser legs pivot on the platform and are fitted with inboard facing feet. When the vehicle's power take-off (which is used to power the platform hydraulic system) is engaged, the two legs are automatically lowered until the feet touch the rear tyres. The driver then reverses the vehicle about 300mm (12in) and this pulls the feet under the tyres and lifts the chassis squarely on the stabilising arms.
When the pto is disengaged and the vehicle driven forwards, the stabiliser legs are automat ically disengaged and retracted into their horizontal stowed position by two small hydropneumatic cylinders.
Interlocks prevent the hydraulic boom from being operated unless the Simjax system is properly engaged and the stabiliser legs from being retracted until the boom is properly stowed.
Worldwide patent applications have been made for the Simjax.
