Wireless controlled Enerpac SyncHoist enhances heavy lift

A new wireless-controlled high precision hydraulic load hoisting and positioning system is being introduced to South East Asia by Enerpac to enhance crane performance and safety while reducing costs compared with conventional load positioning methods.

The latest version of the Enerpac SyncHoist system  - which also features diesel power for operational versatility -  offers load manoeuvring vertically and horizontally using one crane to control loads up to hundreds of tons, while reducing the risk of damage from oscillations of wire rope due to sudden crane starts and stops.

Employing intelligent hydraulics to monitor and guide compact but powerful 700 bar double-acting push-pull cylinders integrated into four lifting points above loads, the SyncHoist SHS system is also used for pre-programmed positioning, tilting and aligning of loads and for counterweighting and determining their centre of gravity.

Wireless control of the latest SyncHoist enables a crane driver to more simply perform complex load lifting, shifting and positioning manoeuvres from his cab, ensuring loads remain evenly positioned during the process and performing point load indications and checks where required, says Enerpac Integrated Solutions.

Diesel power means the system can be deployed virtually anywhere without its hydraulic functionality being dependent on fixed or separate power sources, such as generators. This independence is particularly valuable in applications involving remote applications such as oil, gas, mining and energy, and large-scale applications such as bridges, ports, shipbuilding and infrastructure.

“The combination of diesel drive and wireless control means the system is totally self- contained, “ says Enerpac. “There is no need to have power cables laying around or hoses connected between a hoisted object and the pump unit, because this pump unit can be positioned on the load itself – or on the spreader frame used to perform the lift.”

Available in load capacities customised to individual tasks, with system reach of 1500mm from each of several lifting points, SyncHoist offers very high accuracies (+/- 1,0mm), less dependence on weather conditions and vastly improved operating speed and worker safety.

The Enerpac SyncHoist system for cranes is a member of the Enerpac synchronous lifting family, which has already been proven in major applications in South-East Asia. The system is backed globally by the expertise and experience of the Enerpac Integrated Solutions Team.

Available with manual, extended manual and fully controlled PLC system management and control systems, SyncHoist’s functions and applications span diverse industries including construction, engineering, hydraulics, mining and energy, oil and gas, manufacturing and metal fabrication, shipbuilding and safety.

Specific applications include:
*Positioning of roof sections, bridge sections concrete elements, and steel structures
*Positioning of turbines, transformers and fuel rods
*Precise machinery loading, mill rod changes, bearing changes
*Precise positioning of pipelines and blow out valves
*Positioning and aligning of ship segments prior to assembly

Manual control options for the four lifting points with 1500mm system reach include manual control with manual directional control valves; extended manual control with joystick controls and position display; and PLC control with fully closed-loop control system. PLC control options include touch screen, remote wireless control, load and stroke monitoring, load calculations (centre of gravity) and pre-programmable motions and data recording.
