Rail Brake

Knight Global’s MRAA4359 Rail Brake is a bolt-on design that attaches to the majority of load trolleys and end trucks, except for the low profile designs and the TR2000 Series Rail. The MRAA4359 is typically used when the operator needs to lock a trolley or end truck from moving in the bridge or runway rail. The locking feature allows the operator to accurately load and unload parts. MRAA4359’s parking brake is also designed to be used as a drag brake, but a regulator is needed to supply air pressure to the cylinder.
