Enerpac launches Skyffolding system

Enerpac Heavy Lifting Technology has supplied South Korea-based engineering company, KLES, with strand jacks for an innovative tower scaffolding system called Skyffolding.

KLES has developed the system for boiler construction and maintenance in thermal power plant projects. Traditional scaffolding is a stacked structure constructed from bottom to top, concentrating the total load on the base. In the event that lower levels of scaffolding are damaged, it may trigger a complete collapse. In an effort to reduce this risk, KLES has developed the Skyffolding system - a new approach that reverses the order of scaffolding construction from top to bottom.

Typically, 20 Enerpac strand jacks are attached to a heavy girder at the top of the boiler. The strand jack wires are lowered and connected to uphold and lift a support platform, the uppermost support frame of the scaffold system. This enables the safe lift of the pendant-type scaffolding system, keeping deviations in lateral and vertical directions to a minimum.

As an additional safety measure, failsafe fasteners on the suspended platform have been designed such that the grip on the wire rope increases in direct proportion to the load applied as the scaffolding structure grows. This ensures the stability of the entire scaffolding system is maintained, even if structural problems occur at the lower levels, unlike a conventional scaffolding tower.

The Skyffolding system has been deployed for boiler maintenance in a number of major thermal power plants including KOSPO Hadong, KOEN Samchenpo, EWP Dangjin, KOMIPO Boryeong and WP Taean coal-fired power stations.
