Double-girder truss gantry crane

A gantry crane with a truss-type main girder structure. This design effectively reduces deadweight and enhances rigidity, making it particularly suitable for large-span, medium-load applications such as power plant construction, heavy equipment installation, and logistics yards.
Specifications
  • Lifting capacity: 40-100t
  • Span: 20-40m
  • Travel speed: 13-14 m/min
  • Working class: A5
Introduction

The double-girder truss gantry crane is a gantry crane utilizing a truss structure. Two parallel truss main girders form a rigid spatial frame through transverse connecting beams. The lifting trolley runs on rails between the two main girders. The double-girder design offers high load-bearing capacity and协同 load sharing, with lifting capacities exceeding 100 tons. This type of design effectively reduces deadweight and increases rigidity, making it particularly suitable for occasions with long spans and medium loads, such as power station construction, large equipment installation, and logistics yards.

Advantages & Features

Long Span & Economy
The truss structure is the preferred solution for achieving low-cost, long-span designs.
Efficient & Smooth Operation
Utilizes frequency conversion + PLC control, enabling slow speed under full load and fast speed under light load, with smooth lifting and travel, and low impact.
Safe & Reliable
Safety concepts are integrated into design details. Can be equipped with pin-type overload sensors, dual limit switches, and various safety protection devices.
High Level of Intelligence
Optional anti-sway system, intelligent spreaders, and digital management platform enable intelligent operation and remote monitoring.
Lightweight & Energy Saving
Inherits the lightweight design concept of New Chinese Style cranes, reducing deadweight and wheel load through structural optimization, thereby lowering load requirements for the plant or foundation and achieving energy savings.

Main Applications

  • Ports: Used for loading and unloading containers, cargo ships, etc., to improve logistics efficiency.
  • Shipbuilding Industry: For hull assembly, dismantling, and other operations, due to its ability to handle very heavy components.
  • Steel Industry: Suitable for handling, loading, and unloading large items such as steel plates and sections.
  • Water Conservancy Projects: Includes handling heavy equipment and materials during the construction and maintenance of dams, channels, etc.
  • Mines: Used for transporting, loading, and unloading resources such as ore and coal.
