Hi-Force recommends the purchase of pins for easy rotation of the load setting ring(s).
The HFL series of single-acting fail-safe flat cylinders combine the versatility and efficiency of hydraulic power with the safety of a mechanical load-holding function to provide permanent lift capacity in very confined working environments. They are ideal for use in applications where the load needs to be supported for long periods of time, such as bridge work. The HFL series features a single acting load back cylinder with a full length thread for the mechanical load setting ring. All models are only suitable for vertical stroke and are equipped with movable thrust pads as standard.
