Powerful, safe and globally proven skidding system introduced here by Enerpac

Powerful, safe and precisely controllable hydraulic skidding systems are being introduced by Enerpac for the controlled movement of structures ranging from oil, gas and mining plant to bridges, jetties, ships, barges and loadout facilities.

The HSK skidding systems are comprised of a series of skid shoes powered by hydraulic push-pull cylinders travelling over a pre-constructed track, says Enerpac’s international authority on heavy and complex lifting, shifting and positioning projects, Mr Richard Verhoeff.

The systems – which can handle loads ranging from tens of tons to tens of thousands – was used in construction of the world’s first LGN regasifier in Italy, built with 90,000 cubic metres of cement and 30,000 tons of steel, said Mr Verhoeff, who was recently appointed Integrated Solutions Manager for Enerpac in Australasia after extensive experience with Integrated Solutions systems in Europe.

The Enerpac HSK system, which Mr Verhoeff says is highly suitable for Australasia, uses a series of special PTFE coated blocked placed on skid tracks to reduce friction and facilitate control. The skid shoes are connected to hoses to an hydraulic diesel-driven power pack.

Enerpac skidding systems are usually custom-built to individual specifications but are also available in two standard versions:

ModelCapacity per shoeStroke push/pull cylinders
HSK1250141 Tons600mm per stoke, 23.62in 
HSK2500281 Tons600mm per stroke, 23.62in

Both standard skidding systems are available in two varieties, using either a skid shoe jack or a skid shoe beam. The skid shoe jack includes an integrated lifting cylinder. A skid shoe beam is designed for skidding purposes only.

“To calculate the minimum required capacity per shoe, the entire load has to be able to rest safely on two of the four shoes used on the lift section involved. A load of 550 tons, for example, would require the HSK 2500 with its four shoes of 281 tons capacity each.

“Multiple sets can be used to achieve virtually limitless weights in major mining and energy plants, for example, or individual sets can be used to optimise safety and convenience in lighter but still substantial items of static and mobile plant.

“It is a very versatile system that is highly applicable to the major resources and infrastructure projects now under way in Australasia,” said Mr Verhoeff (B, Eng) who will focus on applications here of Enerpac Integrated Solutions capabilities, such as skidding systems, hydraulic gantries for lifting and positioning onshore and offshore plant, SyncHoist crane technology, as well as sophisticated synchronous lifting technology that can safely lift, balance, weigh and launch massive resources structures up to 75,000 tons.

“All of these technologies are proven solutions with which we have had considerable experience globally, and which have been accepted by major companies with some of the world’s strongest safety cultures,” said Mr Verhoeff.
