Hydraulic cylinders with safety lock nut are recommended when loads have to remain in the lifted position over a period of time. The safety lock nut ensures a positive load hold in any position, and work can be carried out beneath the lifted load.
Hydraulic pressure can be released so that cylinders work like mechanical supports. Pumps can be separated from cylinders.
Lifting and moving of large machinery, steel construction, bridges or similar loads, supporting of buildings and foundations.
For all heavy-duty jacking applications where a special safety factor is appropriate like lifting and lowering bridges, supporting buildings and foundations, jacking up heavy machines, steel sections, ship modules or similar loads.
