Description

Overview

Exterior mechanical load scale gives a clear axle group weight reading in kilograms for air-suspended truck or trailer applications. It suits a single height control valve setup and reads up to 30,000kg, so it fits tri-axle groups that need a simple external weight check. The weather-resistant enclosure protects the gauge outdoors, while the push-pull air valve helps isolate the air supply when needed.

Features

• 3.5″ dial face for quick visual reading
• Displays on-the-ground axle group weight in kilograms
• Weather-resistant enclosure with push-pull air valve protection
• Suitable for one axle group with up to three axles and one height control valve

Specifications and Materials

This exterior mechanical load scale mounts on truck or trailer air suspension systems and displays axle group weight after calibration. It suits one monitored axle group, supports one height control valve, and uses a protective polypropylene enclosure with a 3.5″ dial face. Operating temperature range is -40°C to 60°C, and the gauge carries a 3-year warranty. Mounting bracket kit sold separately. Part number: SP0331. For setup and calibration steps, see the official 310 Series installation guide

Compatibility and Fitment

Match the scale to a single height control valve air suspension system before ordering. It is built for one monitored axle group with up to three axles, so it suits the tri-axle mechanical gauge role rather than single-axle, tandem or dual-valve layouts. Also check the mounting position, air line routing and bracket requirement before installation.

Compliance and Safety

Calibrate the gauge against a certified ground scale on level ground, because the reading depends on correct setup. Chock the wheels before weighing or adjusting the system, and make sure the height control valve has fully inflated the air bags. Do not mount the enclosure directly to the chassis or another main beam unless the vehicle manufacturer approves that location.

Trailer Applications

This exterior mechanical load scale suits air-suspended trailers and truck axle groups where operators want a simple external weight display instead of an in-cab electronic system. It works on tri-axle groups with one height control valve, and it gives a fast visual check during loading, dispatch and routine compliance monitoring.
