Enerpac gantry powers substation lift17 January 2019
An Enerpac gantry has been used to handle and position a refurbished 60t electrical substation skid in South Africa.
P&L Machine Moving and Rigging, based in Johannesburg, used an Enerpac SBL500 gantry to move and position the substation skid on a flatbed truck, for transportation to the nearby Kriel Colliery.
P&L assists the refurbishment of skid-mounted electrical substations from local mines around twice a year, at its Benoni warehouse facility.
For the most recent project, the substation was too large to be loaded onto the lowbed inside the warehouse. The refurbished skid was moved to the warehouse exit using a 30t pick and carry machine and large machine moving axles. Once outside, to raise the skid higher for transportation, P&L lifted the 60t skid using its four-leg Enerpac hydraulic gantry. The lowbed truck then reversed underneath the skid, and the skid was lowered onto the vehicle, to be taken to Kriel Colliery where it was offloaded with mobile cranes.
The SBL500 is part of the SBL (Super Boom Lift) series of telescopic gantries and has a maximum lift capacity, with four legs, of 500t. It features self-contained hydraulics and electronics, Intelli-Lift wireless control system, and self-propelled wheels or tank rollers. It is also designed and tested to meet ASME B30.1-2015 safety standards.
Gareth Lucas, director at P&L, said: “We use the Enerpac SBL500 for a wide range of industrial lifting tasks where accurate lifting and positioning are essential. It gives us the flexibility we need when approaching many lifting projects where there is limited working space.”
