Heavy-Duty Lifting Platform for Large-Diameter Pipe Longitudinal Seam Welding

The MH150 gantry-type welding platform is an industrial-grade lifting system designed for high-precision longitudinal seam (LS) welding on extra-large cylindrical workpieces such as wind towers, pressure vessels, or structural steel pipes. With a maximum lifting stroke of 7500 mm and platform span of 15 m × 9.8 m, it offers robust performance, high load capacity, and reliable operator safety systems.


System Overview

  • Structure:
    The system is composed of two vertical columns (upper and lower parts), a lifting platform, lifting mechanism, dual-axis motorized slide modules, safety ladders, and a full electrical control system.

  • Columns:
    Constructed with welded profiles and plates. The upper section includes vertical tracks for precise up/down platform travel. The design ensures excellent rigidity and structural balance.

  • Lifting Platform:
    Made from profile and plate welded frame with anti-slip floor and three-side guardrails. The platform integrates:

    • Guide carriage with six sets of eccentric-adjustable guide wheels.

    • Fall arrest system that mechanically locks the carriage upon chain failure.

    • Two motorized slide units (300×300 mm) for welding torch installation, with rack and pinion linear guidance.

  • Lifting Mechanism:
    Uses dual 3 kW AC brake motors with chain & sprocket drive system, equipped with counterweights for smooth and stable lifting.
