- Temperature range: -30°C to 65°C (-22°F to 150°F)
- Temperature compensated
- Potted electronics for increased water protection
- Remote angle level adjustment from compatible cab mounted display
Applications
Measurement of crane boom length and crane boom angle to horizontal. The wire rope is fixed at the boom tip for the complete boom length measurement.
General Description
The cable reel has 140 ft. (42 m) of extendable, spring loaded, wire rope. The extremity of the wire rope should be fixed to the extremity of the length to be measured. The cable reel ships with an anchor (QTY 1) and cable guides (QTY 4).
The transmitter box on top of the cable reel houses the battery, the radio transmitter and the solid-state accelerometer-based angle sensor.

Application Notes
The angle sensor in the GS112-V2 automatically detects on which side of the boom it is installed when the boom angle is less than 45° to horizontal. For knuckle booms and other applications where the boom angle may go beyond the -90° to +130° range of the GS112-V2, the GS112-02 with 360° angle sensor should be used. Left or right-side installation must be specified when ordering the GS112-02.
Dimensions and Installation
Cable reel placement: find a clear mounting position on the cab side of the first (lower) section of the main boom. The mounting position should be close to the base of the boom; at least 10 ft. (3 m) from the tip of the first section and where the cable reel won’t obstruct free boom movement at all boom angles and slew positions. Furthermore, the reel must be placed such that the cable has a clear straight line to the end of the last section at all boom lengths.
Mount the welding pads. They must be placed parallel to each other, 16 in. apart. Install the pads such that they create a level mounting position in line with the boom when horizontal (0°). DO NOT WELD THE PADS WITH THE REEL ATTACHED. THIS WILL VOID WARRANTY. Correct alignment of the first guide is important to ensure orderly winding of the cable on the reel. When installing the guides, the first guide should be placed close to the cable reel to ensure that the cable wraps properly on the reel. This distance should be no further than 36” from the reel. Install the other guides at the end of each of the intermediate sections and the anchor at the end of the last section. All guides must be aligned so as to permit unobstructed movement of the cable. Proceed with length calibration. Guides may need to be cut to ensure alignment with the reel. Extra length is provided on the guides.
The angle sensor is pre-calibrated and temperature compensated; see the installation section in the user manual for details.
Materials:
The cable reel is entirely made of stainless steel (AISI 304) with sealed bearings and a stainless-steel wire. The transmitter is made of powder coated aluminum.
