BAUMA PREVIEW
Riser Lifting Jack is a self-locking jack that performs automatic locking during lifting , lowering and holding . Available with 54-ton , 90- ton , 136-ton and 181-ton capacities with either pneumatic or electric pumps , the Power Riser Lifter is supplied with 3.5 m pendant cord for airdriven units with pneumatic valves and 6 m pendant cord for electric-driven units , keeping operators away from the load . It is a readilyportable unit with 102 mm ground clearance for transport over rough terrain . A three-position handle , meanwhile , provides easy tilt back and transport , the company says .
Capacities of Enerpac ’ s JS-Series Jack-Up range from the JS-125 ’ s 125 ton capacity to the JS- 750 , s 750 ton capacity , with each solution offering lifting heights from 6 m to 20 m , respectively
together with the SCJ-Series 50T Cube Jacks-Ups . It will also feature the Enerpac Power Riser for safe and mobile load lifting of mining vehicles .
In addition to the hydraulic gantries and cube
jacks , the booth will feature a JS-250 Jack-Up , and multi-point lifting EVO system used to maintain mining shovels .
SBL600 Hydraulic Gantry The SBL600 Super Boom Lift hydraulic gantry is a three-stage telescopic hydraulic cylinder with rectangular boom for increased capacity and first stage lifting capacity of 674 tons ( 611 t ) and 416 tons at the third stage . The SBL600 fits in nicely between the SBL500 and SBL900 gantries , offering a lifting height of 10.6 m , compared with 8.6 m and 11.3 m , respectively .
Jeremy Stubbs , Commercial Director , Enerpac Heavy Lifting Technology , said : “ Ease of transportation is another key benefit of the new gantry . A foldable boom allows for shipping on standard flatbed trucks without special permitting and routing . In addition , with the self-weight less than 9,100 kg , the SBL600 allows for transport of two legs on a single road truck trailer .”
Enerpac Power Riser Lifting Jack The Enerpac Power
Synchronised lifting Accurate synchronised heavy lifting is the hallmark of Enerpac heavy lifting systems , which , the company says , is exemplified by the SCJ-Series Cube Jacks and Enerpac ’ s larger JS-Series Jack-Up .
The Enerpac Cube Jack has set the standard for ease-of-use and productivity for compact , portable lifting solutions , according to the company . It uses a base lifting frame and selfaligning , lightweight steel cribbing blocks – together with automatic incremental locking – to provide high-capacity and stabilised lifting . It is a safer , controlled , more efficient and environmentally friendly alternative to climbing jacks with tropical hardwood cribbing , Enerpac says .
Enerpac JS-Series Jack-Up Systems , meanwhile , are transforming the way many heavy-lift projects are executed , Enerpac says .
The Jack-Up is a synchronised lifting and lowering system with self-contained hydraulics in each unit for uncluttered work areas . Loads are lifted in increments as steel boxes , called “ barrels ”, and are stacked together to form lifting towers to mechanically hold the load . The JS-250 Jack-Up system uses computer controls for seamless synchronous control , raising and lowering all towers at the same time .
Capacities of the JS-Series Jack-Up range from the JS-125 ’ s 125 ton ( 500-ton lift with four towers ) capacity to the JS-750 , 750 ton ( 3,000- ton lift with four towers ) capacity , with each solution offering lifting heights from 6 m to 20 m , respectively .
These flexible solutions can be moved in and out of sites and – importantly – are classified as intrinsically safe , meaning they can be used in the Australian market .
Heavier lifts Enerpac strand jacks pack tremendous lifting capacity into a small footprint , acting like a linear winch .
This sees steel cables or strands guided through a hydraulic cylinder ; above and below the cylinder are anchor systems with wedges that grip the cables or strands . By stroking the
