GWD200 Wireless Dynamometer & Tension Load Link
The GWD200 is an extremely well-built, high-precision digital wireless dynamometer and tension load link designed for demanding industrial hoisting and crane force measurements. Independently innovated by Galoce to meet stringent global standards, the GWD200 handles capacities from 1 ton up to 200 tons. Engineered with premium powder-coated materials (lightweight aluminum for 1-5t; high-strength alloy steel for 10-200t), it is equipped with high-tension galvanized G2130 anchor shackles. Combined with our self-developed wireless 380 handheld indicator, it delivers unmatched portability, ultra-stable data transmission, peak force capture, and automatic set-point control.

⚙️ Telemetry Operation & Handheld Controller Integration: The GWD200 is paired with high-tensile anchor shackles for flexible hanging. Gravity acceleration coefficients can be regulated directly through the handheld indicator to adjust for geographic variance. Key mechanical operations—including on-site password calibration, peak hold value tracking, one-key tare, and zero balance adjustment—are easily controlled via the indicator's 4 mechanical keys.

Frequently Asked Questions
1. What is the difference between GWD200 and traditional S-type tension sensors?
For high-capacity overhead lifting, S-type cells can struggle with rotation and off-axis loads, and they lack local screens. GWD200's link-body style with standard G2130 galvanized shackles offers superior mechanical alignment and stability, handles extreme dynamic lateral vibrations, and displays weights on both the body and the wireless indicator.
2. Can I use GWD200 in long-distance environments, and is the signal reliable?
Yes. GWD200 communicates with the handheld wireless 380 indicator over a reliable 2.4 GHz channel with a standard range of 80 meters (line-of-sight). For locations with massive steel structures or long distances, we can customize a 433 MHz/868 MHz telemetry frequency extending range up to 200 meters.
3. What safety features protect operators during high-tonnage lifting?
Rigging safety is our priority. The GWD200 is built with a massive 125% safe overload threshold and a 400% ultimate breaking strength factor. An alarm alerts operators immediately at 100% F.S. + 9e on the screens, and set points on the indicator can be wired to trigger automatic safety winch shutdowns.
4. How can we export testing logs or integrate data with our local PCs?
Our self-developed handheld 380 indicator features a standard built-in RS-232 serial communication interface. This allows continuous string data stream output. You can directly plug it into printer systems, link it to PCs for database logging, or display figures on external large scoreboards.
5. Are the batteries easy to replace, and what is the battery lifespan?
Yes. GWD200 uses highly accessible, standard alkaline batteries instead of specialized lithium packs to prevent shipping and replacement hassles. The load link body runs on 3 x LR6 (AA) batteries, and the indicator runs on 4 x LR6 (AA) batteries. They deliver a robust battery lifespan of over 50 hours of continuous active use.
