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 Switcheleasing the coil spring thus pulling the cable/chain to actuate shutdown. The spring, when fully compressed, exerts a pull of 30 lbf (133 N).
Operating Force: 30 lbf (133 N) maximum, 10 lbf (44 N) minimum.
Coil Resistance: RP75-12: 32.2 ohms.
Length of Travel: 1-7/8 in. (48 mm).
Control Linkage Cable: 4ft. (1.22 m)
