BVA Hydraulics HLN1004, High Tonnage, Lock-Nut Style, Hydraulic Jacking Cylinders
The engineered lock nut feature on BVA Hydraulics HLN Series high tonnage, hydraulic jacking cylinders engage with the plunger to create a mechanical load-holding feature. Simply, as the plunger begins to rise, a time-out can be enacted to allow the lock-nut to be screwed down against the cylinder body. Repeating this process throughout the lift adds a great level of safety to any lifting project.
