Description

The RP75 rack puller is a semi-automatic device

that provides a pulling force to initiate shutdown

of diesel engines and equipment.

The RP75 connects to the injection pump or air

intake shut-off lever via a cable (chain optional).

A coil spring, within the RP75, is reset manually

and is held in place by an electromagnet. When

the SWICHGAGE

detects a malfunction, the

electromagnetic circuit is interrupted through a

Magnetic Switch–releasing the coil spring thus

pulling the cable/chain to actuate shutdown. The

spring, when fully compressed, exerts a pull of 30

lbf (133 N).

The RP75 is available for 12 or 24 VDC applica-

tions and is compatible with all SWICHGAGE

instruments.
