Enerpac’s new SL100 and SL200 hydraulic gantries offer higher lifting capacities and accurate load positioning on a narrow 610-mm track gauge. Ideal for machinery and industrial moving specialists, these models have lift capacities ranging from 100 t to 200 t respectively and feature two stage lift cylinders with a maximum lifting height of up to 4.75 m (SL100) and 6.7 m (SL200). Typical industrial moves applications include transportation and installation of presses, machine tools, electrical transformers and injection moulding machines.
Designed for safe lifting in confined or limited-access spaces, the new SL gantries are easy to mobilise and demobilise and include self-contained hydraulics allowing quicker and safer deployment. Each gantry leg features self-propelled wheels for travel along a narrow gauge track together with an Intellilift synchronised control system, providing wireless control, unrestricted operator position, and automatic synchronisation for lifting/lowering and travelling.
Additional components and accessories are available such as header beams, lifting anchors, side shifts and skid tracks. There are also tarpaulin covers, transport frames for side shift units, slings and shackles. According to Enerpac, all of its gantries are CE & ASME B30.1 compliant and tested at maximum capacity at maximum extension and tested under witness of Lloyd’s Register.
Another new product from Enerpac is the SCJ50 50T cube jack. It is designed to provide an alternative to traditional climbing jack systems and works in a similar way to Enerpac’s current jack-up system but without the necessary electrical controls. The SCJ50 cube jack offers contractors a safer alternative to jack and pack with wooden cribbing, said Enerpac.
The SCJ50 50T cube jack also has a significantly smaller footprint, providing heavy lift contractors with a more stable lift up to 2 m and where space is restricted. Safe operation is built-in with the self-locking design. Blocks are stacked manually, with a mechanical lock on the up stroke and down stroke. The operation is incremental; at the end of the up stroke the lock will engage. Once engaged the lift cylinder is retracted and another block is safely added.
In addition, the Enerpac ETR1250 trolley system provides an alternative method with increased benefits over traditional skidding methods. It comprises electrically-driven trolleys that can carry heavy loads along a fixed rail system. Compared with skidding systems, the trolley offers continuous movement allowing for significantly faster travel.
The ETR1250 trolley system has been successfully deployed on a jack-up vessel for a recent GeoSea Geotechnical & Offshore Solutions project. This involved the movement of 500-t offshore wind monopile transition pieces some 90-m across the ship’s deck to within range of the on-board crane for offshore installation.
