General Purpose Double Girder Gantry Crane
The General Purpose Gantry Crane is a large-scale hoisting machine. Its metal framework consists of the main girder, supporting legs and crane travelling mechanism. All key structural parts are fabricated from premium Q355B and Q235B structural steel, guaranteeing outstanding structural strength and long service life.
Equipped with high-performance planetary reducers in the upgraded core drive system, the crane delivers smoother operation and improved energy efficiency. Benefiting from its large effective span and high ground space utilization rate, it serves as highly efficient material handling equipment for modern bulk logistics and industrial production lines.
Designed and manufactured in accordance with Chinese national standard GB/T 14406 General Purpose Gantry Cranes, the crane is extensively applied for bulk cargo loading and unloading at outdoor storage yards, port bulk cargo zones, factory workshops, stockyards and railway freight terminals.
It operates with low noise to satisfy the environmental standards of modern eco-friendly factories. Its compact overall structure also enables flexible arrangement within limited working spaces.
