Product Introduction

Double is stronger! If you need to transport heavy loads more than 50t across large areas or have high work duty, then double girder traveling cranes are your first choice. Due to various main girder connection options, the double girder overhead crane integrate well into different building structures, whether new or existing.

They can be utilized at any capacity where extremely high hook lift is required because the hook can be pulled up between the girders.

Double girder overhead cranes can be fitted with maintenance platforms under motors, on the rigging or over the full span of the roller beam. It can be offered for a very large range of spans, heights of lift as well as customized speeds depending on your application. They can also be provided with multiple hoisting trolleys running on the same bridge or auxiliary hoisting mechanisms on the main trolley.

Technical Features

  • The main beam adopts a truss structure, which has the advantages of light weight, large load, and strong wind resistance.
  • The pin and bolt link is disconnected every 12 meters, which is convenient for transfer and transportation.
  • Adopting walking forward, the middle outrigger does not walk on the bridge deck, so there is no need to erect a longitudinal moving track. This can save construction costs and improve erection efficiency.
  • The outrigger has an adjustable angle core plate, which can adapt to the inclined bridge at any angle below 45°.
  • The vehicle is equipped with Siemens or Schneider electric spare parts as standard
  • Optional: frequency conversion to adjust speed
  • Optional: safety monitoring, PLC control
  • Optional: Diesel generator set
