Global hydraulics and heavy lifting technology specialists Enerpac are introducing to Australasia a new low-height skidding system – which stands at just 92mm with the track – for the accurate positioning of heavy loads in tight and awkward spaces.
The new Enerpac LH series low-height skidding system is a modular track system that can jack and slide heavy loads, such as transformers, generators, motors or drives, over a pre-constructed track.
“Skidding systems are ideally suited to tight spaces where cranes aren’t able to access the load effectively. The new low-height system takes this one step further by using a rigid, durable design that can access even tighter spaces, while still providing high lifting capacities,” says Warren Baltineshter, Mining and Heavy Lifting Technology Manager, Enerpac Australia.
“Skidding systems are typically 200-600mm high, which is still an enormous advantage when cranes can’t access a lift site, but the Low-Height system, at just 92mm, opens up possibilities in even tighter, more compact applications,” he said.
The low-height skidding system is comprised of a series of skid beams moved by hydraulic push-pull units, travelling over a pre-constructed track. A series of special PTFE-coated pads are placed on the skid tracks to reduce friction. The push-pull units are powered by a standard Enerpac Split Flow Pump to ensure each skid beam travels synchronously.
“When using two skidding units together, the maximum capacity is 3,560 kN of force, which can lift 400 tons, utilising 700 bar (10,000 PSI) hydraulic pressure,” says Baltineshter.
The low-height skidding system has a push-pull stroke of 600 mm and is designed to easily change skidding direction, using Enerpac’s globally proven hydraulic pumps and cylinders.
Customised solutions can be implemented for complex projects, such as utilising optional track support and connecting both power units together to provide synchronous travel of the load. Such a configuration would be used in applications like transformer outage maintenance.
In addition to its low height, this system offers a 2-in-1 design. It can be used either on a fully supported surface or combined with the optional track support for added rigidity when the support surface is not fully supported or when spanning a gap is necessary. This two-part design means operators do not need to own two sets of tracks for various ground support conditions.
