For the sake of simplicity, the pedal structure of the crane control room of the present invention is simply referred to as the present structure below.

The use method of the structure comprises the following steps: the mounting hole on the mounting bracket of the structure is mounted below the control cabin through a bolt, and when the structure is used, the pedal is pulled out of the sliding groove forwards, so that the limiting block is in contact with the limiting bolt, the second lock hole is opposite to the first lock hole on the rear side, and then the second lock hole is connected with the first lock Kong Wancheng on the rear side through the lock pin to be locked. After the pedal is used, the lock pin is taken out firstly, then the pedal is pushed backwards into the sliding groove, so that the second lock hole is opposite to the first lock hole positioned on the front side, and finally the second lock hole is connected with the first lock Kong Wancheng through the lock pin to be locked.

The advantage of this structure: this structural mounting provides the strong point in the crane control room below for operating personnel gets into the control room, has shortened the span, has eliminated the potential safety hazard, wholly adopts the pull structure, and the time spent can contract foldingly not influence the hoist normal operating. All bolts mainly bear radial load, large displacement is avoided in the axial direction, the falling risk is small, waist-shaped holes are adopted in the L-shaped angle iron horizontal portions, and size adjustment can be conducted according to needs to meet installation requirements of different crane control chambers.
