Hydraulic Rod Clamp
AMLOK RCH Series cylinders retain load on hydraulic power or pump failure.
Advanced Machine & Engineering Co. (AME) introduced its AMLOK Hydraulic Series RCH Rod Clamp that provides power-off clamping of rods and shafts. The clamps are actuated by a spring/collet mechanism and unclamped by hydraulic pressure. The clamp mountings are designed to apply to standard heavy-duty NFPA-style MF1 cylinders. The standard housing can be mounted to any machine structure or be custom-designed to suit an application. The holding force depends upon the rod diameter and the amount of hydraulic pressure (PSI) available for unclamping. The AMLOK is preset at the factory to release at the specified hydraulic pressure. The clamps are designed for locking reciprocating motions only. Special units are also available for both rotating and reciprocating motions.
