Intellilift provides the operator with information about the stroke, lift and load per unit and automatically corrects any unsynchronised motion of the individual units, as well as unobstructed views of the load for a safer lift. Moreover, the gantry lift is less affected by wind speeds than using cranes, allowing the gantry to be used at up to four times the wind speed permissible with a crane. A gantry can be used in areas where crane access is impractical, and it allows a continuous lift onto SPMT’s (self-propelled modular transporters) that is more efficient and safer than traditional jack and pack used on smaller bridge decks, says Enerpac Australasia mining and heavy lifting technology manager Warren Baltineshter. Several of these advantages demonstrated in practice in the Chester Line lift, where “the Enerpac gantry was the ideal lifting system for this bridge deck replacement project,” says Nigel Fletcher, managing director, Osprey Heavy Lift Ltd. “Working at ground level and the ease of lifting the deck onto an SPMT made for a smooth installation of the new bridge desk,” he says. LOW-RISK DEPLOYMENT An Enerpac hydraulic gantry is cost effective to mobilise. The gantry’s telescopic leg can be folded down for ease of transportation, either on a flatbed trailer or in a container. Once on site, the gantry allows the new deck to be completely constructed on-site at ground level, avoiding the need for working at height requirements. Gantry lift systems are part of the Enerpac range of heavy lift, shift, balance and place solutions, which includes the world’s largest portfolio of heavy lift and load control applications. Enerpac systems – such as hydraulic gantries, strand jacks, skidding systems, self-erecting towers, SPMTs and synchronous lift systems – can handle some of the world’s most challenging lifts, including awkwardly shaped and sometimes massive structures weighing tens of thousands of tons in maritime, mining, energy and heavy industrial applications. www.engineeringnews.co.nz 45
