A NEW wireless-controlled hydraulic load hoisting and positioning system from Enerpac South-East Asia enables a single crane to precisely position heavy and unbalanced loads. The SHAS Series Synchronous Hoist System is a below-the-hook crane attachment operated by a single wireless controller to provide accurate, safe and cost-effective positioning of loads without the need for multiple cranes.

The Enerpac SHAS Series allows a single operator to control the SyncHoist.

SHAS comprises four, double acting, push-pull cylinders connected to lifting points above the load by cables or under an optional auxiliary frame enabling accurate hoisting where space is limited. The lifting cylinders are available with 110 and 225 ton lifting capacities each, plunger strokes of 1 and 1.5 metres and capable of high precision lifting accuracy over the full stroke.

Each double-acting cylinder features integrated pump and controls, a system that eliminates the need for an external power pack and removes the complexity of hydraulic hoses and connectors.

“Wireless remote control means a single operator can control the SyncHoist while moving around the lifted load at a safe distance, observing the lift in progress and making real-time adjustments,” says Enerpac integrated solutions manager for South East Asia Maxim Lee.

The operator has full control over load handling; each cylinder can lift or lower independently. The system can perform several types of movements, including synchronous lifting and lowering, balancing and tilting, all of which can be pre-programmed.

“SHAS technology is applicable to all industries where tower, crawler, mobile and overhead cranes are used to lift odd-shaped loads with off-centres of gravity. SHAS systems are especially useful for fine positioning of loads because of their outstanding control, safety and time-saving cost-efficiency,” says Maxim Lee.

“For example, elevated motorway bridge sections and MRT track systems can be lifted into position quickly with just one mobile crane while working in confined construction areas in even the busiest South East Asian cities. Such time savings translate into major savings in cost and disruptions avoided because construction schedules can be shortened.”

“Another advantage of the SHAS system is that it’s fully compliant with global standards, so it can be used on projects all over South East Asia and globally, meeting the strictest safety codes and standards.”
