Hydraulic cylinders with safety lock nuts are recommended when loads have to remain in the lifted position over a period of time.

The safety lock nut ensures a positive 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.
