Hydraulic Cylinder Rod Locking Device

Tie rod cylinder with kfh z series rod locking unit shorter build length than the kfh x but height and width of the kfh z are greater.

Hydraulic cylinder rod locking device. In the event of an electrical hydraulic power loss the potential energy of the internal bellville washers load a conical piston driving it over the friction fingers resulting in securing the load. Hydraulic rod clamping device and locking unit from hänchen the patented hydraulic clamping device ratio clamp hold the rod in a standstill and locks it into position mechanically. A device for locking a piston rod of a hydraulic piston and cylinder assembly in an extended condition so that mobile construction equipment or other heavy machinery cannot be driven from a job site. In the event of an electrical hydraulic power loss the potential energy of the internal bellville washers load a conical piston driving it over the friction fingers resulting in securing the load.

When hydraulic or pneumatic pressure is applied to the normal inlet port the locking piston is moved off the balls thus unlocking the piston rod to travel the required stroke length. Operating principle the safety rod locking device is mounted at the head end of a hydraulic cylinder. Hydraulic cylinders rod locking device. Bear loc has a patented design based on the principle of elastic expansion of metal under pressure.

Rod end lock min. The locking device is placed in ensleeving relation to an extended piston rod between a proximal hydraulic cylinder and a distal bearing point to prevent retraction of the piston rod. It clamps the piston rod without loss of position in one continuous. The prl rod lock is a precision locking device therefore strict rod tolerances and rod material specifications are required to ensure safe and proper operation.

The bear loc can be supplied with a hydraulic cylinder or used with existing cylinders. The ratio clamp is unlocked by hydraulic pressure. Bear loc units can be supplied in a wide variety of configurations for locking both liner and rotary motion. Cylinder piston rod is re locked automatically by simply returning the rod back into the lock mechanism.

The clamping effect is immediate lasts for an unlimited period of time and doesn t require an energy supply suitable for various applications as a safety. The ratio clamp is unlocked by hydraulic pressure. The hänchen ratio clamp is a positive rod clamping safety device. Bear loc is a simple reliable locking device that can be used where infinite position locking zero backlash and high system stiffness are required.

Quantity required number of units cylinder bore rod size diameter mounting style e g. Minimum requirements for the rod materia include a chrome plated surface finish of 10 microinches or less and a surface hardness of 52 rc.
