Product Introduction
GB crane rails, according to the clear definition of national standards, are special rails used in crane travel systems to provide reliable guidance and stable support for cranes. Among them, GB QU120 crane rails, with their wide and thick rail heads and sturdy rail bodies, can withstand extremely high pressure and shear force. In large logistics transfer centers, large hydropower station construction sites and other places, they help cranes complete various difficult material handling tasks and ensure the smooth progress of the operation process.
Due to the high requirements for the hardness of crane rails, especially QU120, which is often used in crane rail specifications in large industrial facilities, it often uses U75V material. The vanadium content not only greatly improves the hardness of the rails, but also greatly improves the wear resistance, impact resistance, toughness and other properties of the rails. It can well withstand the huge wheel pressure and impact force during the operation of the crane, ensuring that the rails are not prone to breakage during use, and have high stability.

Product Packaging & Delivery
Use steel belts or steel wires to fix the rails to prevent them from being bumped during transportation. In order to prevent the rails from corrosion, anti-rust oil will be applied to the surface of the rails or plastic film will be covered on the upper layer of the rails. The outer packaging label can use the local language according to the customer's requirements.
How to install crane rails?
QU120 crane rail installation steps are as follows:
Preparation before installation: Check the quality of the track, prepare installation tools such as cranes and electric welders, and clean the foundation surface.
Track laying: Positioning and laying out, laying pads, hoisting tracks, and adjusting the elevation and straightness of the track with a level and theodolite.
Track connection: Welding connection can be used, pay attention to controlling welding deformation and testing weld quality; fishplate connection can also be used to ensure uniform gaps and tighten bolts to the specified torque.
Fixing the track: Install the pressure plate to fix the track, and then perform secondary grouting, filling the gap with non-shrinkage cement mortar.
Post-installation inspection: Perform appearance and size inspections, as well as crane no-load and load test runs to check whether the track and crane are operating normally.
