20 Ton Gantry Crane Solution For A Railway Yard In Kazakhstan

The Customer Requirements

  • The customer operates a railway yard in Kazakhstan and needs to use a 20 ton gantry crane to load and unload steel to improve operational efficiency and safety.
  • The gantry crane will be used at low temperatures of -40°C, so it required consideration of several factors such as material selection and structural design.

Our Solutions

  • An AQ-MH 20 ton single girder gantry crane was chosen as the optimal solution. It was designed with a span of 32m, a lifting height of 15.6m, work duty of A3, effective cantilever length of 8+14m, cabin control and remote control.
  • To ensure normal use at low temperatures of -40°C, the 20 ton gantry crane was made of steel materials with good low-temperature performance. During the manufacturing process of the gantry crane, welding temperature and welding speed were strictly controlled to prevent welding cracks. We also selected lubricating oil with good low-temperature performance and adopted a heating system to ensure the fluidity of the lubricating oil.
  • This single girder 20 ton gantry crane was also designed with the tie rod structure to provide additional stability to the crane structure and prevent it from swaying or deflecting under heavy loads or external forces.
  • We also selected constant tension cable reel power supply system for the 20t gantry crane, which ensures that the cable maintains tension during crane operation, preventing cable breakage and damage. The constant tension cable reel power supply system includes a series of protective devices, such as overload protection, short circuit protection, and grounding protection, to ensure the safety and reliability of the power supply system.
