Description

Overview

Exterior mechanical load scale gives a direct axle group weight reading in kilograms for air-suspended truck or trailer applications. It is built for tandem axle groups with one height control valve, so it suits operators who want a simple external gauge rather than an in-cab electronic display. The weather-resistant enclosure protects the gauge outdoors, while the push-pull valve lets the operator isolate air to the gauge during use and calibration.

Features

• 3.5″ dial face for quick visual reading
• Displays on-the-ground axle group weight in kilograms up to 25,000kg
• Designed for tandem axle groups with one height control valve
• Weather-resistant polypropylene enclosure with push-pull valve protection

Specifications and Materials

This exterior mechanical load scale mounts to truck or trailer air suspension systems and reads axle group weight after loaded calibration. It is the single-height-control-valve version for tandem axle groups, and it uses a black polypropylene enclosure with a 3.5″ dial face. Operating and storage temperature range is -40°C to 85°C, and the scale carries a 3-year warranty. Mounting bracket kit sold separately. Part number: SP0335. For setup and calibration steps, see the official 310 Series installation guide

Compatibility and Fitment

Match this scale to a tandem axle air suspension system with one height control valve before ordering. It monitors one axle group with up to two axles, so it does not suit tri-axle or dual-height-control-valve layouts. Also check the mounting position, bracket requirement and air line routing, because the enclosure needs a protected and accessible location.

Compliance and Safety

Calibrate the gauge against a certified ground scale on level ground, and do not calibrate it empty. Chock the wheels before weighing or adjusting the suspension, then make sure the height control valve has fully inflated the air bags. Do not mount the scale directly to the chassis or another main beam unless the vehicle manufacturer approves that location.

Trailer Applications

This exterior mechanical load scale suits tandem axle truck and trailer air suspension where operators want a simple way to check legal axle group weight during loading, dispatch and day-to-day fleet work. It also suits replacement of a same-size external air suspension gauge where a clear kilogram display and weather-protected housing matter more than electronic features.
