The Electric Hoist Truss Gantry Crane (MHHType) is a medium-to-small-sized rail-mounted lifting device manufactured by Henan Mine, featuring a lightweight truss structure welded from angle steel or I-beam that offers excellent wind resistance and cost-effectiveness for outdoor material handling operations . This crane is used together with CD1, MD1 or other models of electric hoists, with the hoist traveling along the lower flange of the main beam's I-beam to complete lifting operations, and the gantry frame consisting of main beam, legs, lower crossbeam, traveling mechanism, and electrical control system .

The crane's truss structure provides advantages such as light dead weight, strong wind resistance (wind pressure less than 125Pa), simple structure, easy installation and maintenance, and small windward side, making it particularly suitable for outdoor yards, ports, freight terminals, and windy environments . Typical specifications include lifting capacity from 3 to 32 tons (standard up to 20 tons), span from 12 to 30 meters (customizable to 35 meters), lifting height from 6 to 9 meters (customizable up to 12 meters), working temperature range from -20°C to +40°C, and working duty class A3 to A5 . The crane supports multiple control methods including ground pendant control, wireless remote control, and cabin control, and is forbidden to be used for lifting molten metal, flammable, explosive, or corrosive materials .

This crane is widely used in construction sites, precast concrete yards, steel service centers, shipyards, railway maintenance depots, container handling stations, mining sites, and logistics hubs.

Core Applications – Electric Hoist Truss Gantry Crane
1.Outdoor Yards & Freight Terminals – Loads, unloads, and stacks general cargo, steel coils, pipes, and construction materials in open-air storage yards, with truss structure providing strong wind resistance for windy environments.
2.Ports & Wharves – Transfers bulk materials and general cargo from vessels to trucks or storage areas, with rail-mounted design enabling stable operation and optional cantilever extending reach beyond rail centers.
3.Warehouses & Logistics Centers – Handles pallets, finished goods, and raw materials in semi-covered or outdoor storage facilities where building structures cannot support overhead cranes.
4.Construction Sites & Precast Yards – Transports steel reinforcement, precast concrete components, and construction materials in open staging areas, with lightweight truss structure allowing easy relocation and installation.
5.Mining & Metallurgy – Moves ore, coal, and bulk materials in mining yards and steel plants, with heavy-duty configurations available for high-frequency operation and harsh conditions.
6.Bridge & Infrastructure Projects – Performs material handling for bridge construction, hydroelectric power stations, and large-scale infrastructure projects, with truss design providing large spans and excellent wind resistance for open-air worksites.
