Installation Prerequisites

1. The installation of the rail clamp must be carried out after the adjustment of the lifting surface steel beam is completed.
2. The crane steel beam must meet the requirements of the “Code for Construction and Acceptance of Steel Structure Engineering” (GBJ205 – 83) and current steel structure codes.
3. The rail clamp should be installed before the rail installation.
4. The surface of the crane beam before the installation of the rail clamp must be finished and meet the requirements of current regulations.
5. Before installing the rail clamp, the rail joints should be connected, and the deviation of rail joints and side bends should meet the requirements of the “Code for Steel Structure Engineering and Acceptance” (GBJ205 – 83). For rails with allowable deviations, they must be calibrated and constructible.
6. The welding of the bottom plate control board and the steel hanging beam should meet the design requirements.

Installation Sequence and Essentials

1. Welded Fixed Base: Use a fixed base with three grooves on the surface and the center position of the rail presser. The allowable deviation of the position from the centerline of the crane beam is ±1.0mm.
2. Insert T – bolts: Put in T – bolts and push them in the direction of the rails.
3. Install Adjusting Plate: Put in the wedge – shaped adjusting plate, make the notched surface upward.
4. Assemble Components: Install rail pressure plate, washers, spring washers, and nuts in sequence.
5. Adjust Position: Move the wedge – shaped adjustment plate to adjust the position of the rail clamp perpendicular to the rail. When the rail clamp is tightly compressed with the lower flange of the rail, tighten the nut.
6. Consider Welding Influence: The influence of welding the fixed plate on the disturbance change of the crane beam should be considered during design or construction.
