Product Description
20T Dual Hoist Single Girder Overhead Bridge Crane
A5 working class industrial crane with customizable span for workshops, featuring dual hoist configuration for enhanced operational efficiency.
Product Overview
The 20T Single Girder Overhead Bridge Crane is a light-duty rail-mounted lifting system comprising main girder, end carriages, electric hoist, and electrical control system. This model combines single girder structure with electric wire rope hoist, ideal for material handling in factory workshops, warehouses, and storage yards. With compact design, easy installation, and excellent cost-effectiveness, it supports maximum lifting capacity of 20 tons with moderate working frequency.
