Double girder dam top gantry crane

One way door double girder dam top gantry crane is installed at the top of the dam, and the cart can move in the direction of the dam. The porous gate on the same center line can be opened and closed. Most are used to open and close accident repair gates and tailgates.

Features of one way door double girder dam top gantry crane

1. The opening and closing force is large, which is suitable for the opening and closing of the gates of large-scale water conservancy power stations;

2. The car has no running mechanism, only the cart running mechanism;

3. Easy operation and maintenance, realizing on-site and remote control operations.

Two-way double-turn double girder dam top gantry crane

Two-way double-turn double girder dam door machine is similar to the two-way door machine. The cart moves in the direction of the dam and the trolley moves in the direction of the water flow. Generally, there are multiple sets of grab beams, which can open and close the porous gates and trash racks on different center lines on the dam. The upstream or downstream legs of the door machine are equipped with rotary cranes. The radius of rotation of each rotary crane can reach 180°, which can assist the transportation and installation of the equipment on the dam.
