Locking Collar Hydraulic Cylinders available for Hire

Locking collar hydraulic jacks are manufactured to mechanically lock the ram after lifting, making them safe and reliable. Our jacks are designed and manufactured in-house to withstand the toughest of environments making them ideal for bridge jacking and many other holding applications.

We offer over 35 different models of screwed ram locking collar hydraulic jacks from 10 to 1000 tons capacity and strokes from 15mm to 300mm. We continuously increase our hire stock to meet new load and stroke requirements by our customers, custom designs can be easily manufactured to suit your particular application. There are two basic designs, firstly the preferred type (glanded) which are fitted with a top cylinder end-stop to avoid accidental over-stroking occurring and provide additional piston guidance increasing the lateral restraint capacities of the hydraulic jack. The second type is (pot) used when the height of the jack needs to be reduced to a minimum, the disadvantage is that the cylinder is more vulnerable to damage, the piston has no end-stop and lateral restraint capacity is greatly reduced. Both types are fitted with spherical (tilting) heads to ensure that the load is transmitted centrally through the jacks piston.
