J&R LIFT-N-LOCK® Hydraulic BOOM Gantries are available with lifting capacities from 75 US ton (68.1t) to 1,800 US ton (1634t) with four lift housings and lift heights from 18 ft. (5.48m) to 100 ft. (39.48m).
Hydraulic gantries have become standard equipment in the lifting business today because of their cost effectiveness and project versatility. J&R Engineering LIFT-N-LOCK® Hydraulic BOOM Gantries, with their increased height capabilities and ultimate safety features, require considerably less of an investment than mobile or overhead cranes, and can perform many of the same tasks. Gantries can also work in confined spaces or low overhead areas while remaining mobile and easily transportable.
All J&R Engineering Gantries feature our exclusive LIFT-N-LOCK® cam locking technology, which provides true continual load protection throughout the duration of the lift. In the unlikely event a lift cylinder would lose pressure or otherwise fail, our system will immediately engage to hold the load in place. Select models include our innovative OCTAGON high strength boom design. This has quickly become a popular option. Other Standard features on LIFT-N-LOCK® Gantries include:
Double Acting Cylinders
Oscillating/Rotating header plates
Steel Hydraulic lines
Integral Self Propel w/ customized wheels
Integral Lock Valves
Pressure compensated Controls
Two speed load sensing
Available options include PowerLink powered lift links, Dual Digital Height Indication System, Stabilizer Bars, Sideshift Endtruck Trolley System (S.E.T.S.) and our brand new Powered Rotator Frame.
