TWH/TWM Series: Professional Solutions for Heavy-Load Conveyors


The TWH, TWM, TDH, TDM, TTH, and TTM series are the "Heavy Artillery" of pneumatic stopper cylinders. Engineered for the most demanding automated production lines, these lever-type actuators are designed to halt heavy pallets (up to several hundred kilograms) moving at high speeds with absolute precision and zero damage.

Technical Design & Engineering Highlights

  • Massive Impact Resistance: Unlike standard vertical stoppers, these series utilize a reinforced lever mechanism that converts horizontal impact into controlled vertical energy absorption.

  • Integrated High-Capacity Shock Absorber:

    • "H" Series (TWH, TDH, TTH): Focuses on Heavy-Duty structural stability for maximum impact force.

    • "M" Series (TWM, TDM, TTM): Features integrated Adjustable Shock Absorbers to fine-tune the deceleration based on the specific load weight and conveyor speed.

  • Superior Lateral Load Design: Equipped with extra-thick pivot pins and high-precision guide bushes to prevent mechanical wear and ensure a service life of millions of cycles.

  • Robust Aluminum Body: Hard-anodized aluminum alloy body provides excellent corrosion resistance and includes integrated T-slots for flush-mounted magnetic sensors.

  • Safety Lock-Out: The mechanical toggle design ensures that the lever remains securely in the stop position even under fluctuating air pressure.
