The rear half part of the carriage body 12 on the side provided with the operation door 14 is a fixed baffle plate 19, the operation door 14 is positioned in front of the fixed baffle plate 19, the front side of the operation door 14 is hinged with the carriage body 12 through a hinge, and a door bolt 20 is arranged between the rear side and the fixed baffle plate 19.

The operating seat 11 is a back rest chair with armrests and a backrest.

The frame 15 is a square frame structure with one side open.

The framework 15 is a U-shaped framework structure with one side open.

The folding top cover 13 is buckled on the upper part of the compartment body 12 in a fan shape when being opened, and is folded at the upper side position of the rear half part of the compartment body 12 when being folded.

The foremost framework 15 of the folding top cover 13 is provided with a top cover handle for folding and opening the folding top cover 13.

The soft top cover curtain 16 is a transparent rainproof soft curtain.

The hydraulic pressure distributor 22 and the electrical equipment control box 23 of the crane operation device 2 are provided in the car body 12 in front of the operation seat 11.

In the second embodiment, as shown in fig. 2, the difference from the first embodiment is that the hydraulic distributor 22 of the lifting operation device 2 is located below the operation seat 11 and is installed in the carriage 12, and the electrical control box 23 of the lifting operation device 2 is located opposite to the operation door 14 and is installed on the side wall of the carriage 12.

Instructions for use:

when the crane operation room is used, one side without the operation room door 14 is installed on an upright column side plate of a crane turntable of the lorry-mounted crane (the crane operation room can also be installed on the crane turntable), the upper side of the carriage body 12 is lower than the maximum 4 m height of the lorry-mounted crane in a normal running state, the height of the folding top cover 13 when being opened and buckled on the carriage body 12 can be higher than (shown in figure 3) or lower than (shown in figure 4) the national standard of 4 m, and a climbing ladder needs to be arranged on the crane of the lorry-mounted crane for the crane operation room 1. When the installation position of the hoisting operation room 1 is higher, the sitting position of an operator is higher, the visual field is better, and the hoisting operation is more convenient to observe. However, since the foldable top cover 13 causes the vehicle to be very high, the foldable top cover 13 needs to be folded on the carriage body 12 before the lorry is turned to the driving state. When the installation position of the hoisting operation room is lower, the position where an operator sits is lower, the observation visual field is poor, but the problem of superelevation does not need to be considered, and the lifting operation room is more convenient and trouble-saving to use. Both methods have advantages and disadvantages.

The function of the safety device is as follows:

since the lifting operation room 1 is installed on the crane boom upright post, the position of the operator is high, and in order to prevent the lifting transport vehicle from being overhigh, the height of the lifting operation room 1 is designed to be low, and the height of the carriage body 12 is lower than the national standard of 1.2 meters. Because the operator can observe and operate the folding top cover 13 more conveniently when opening, because the height of the carriage body 12 is lower, if the operator stands up in the lifting operation room 1, the operator can easily fall down from the carriage body 12, and the safety is not guaranteed. Therefore, for safety, the safety device 3 is designed to be composed of a safety pedal 31, a gravity safety trigger switch 32 and a pressure relief solenoid valve. Normally, the operator sits on the operation seat 11 to operate, the weight of the operator is mainly borne by the operation seat 11, the pressure of the foot on the safety pedal 31 is smaller than the pressure set value of the safety pedal 31, and the gravity safety trigger switch 32 is not triggered. If an operator stands up in the hoisting operation chamber 1 to operate, the operator can step on the safety pedal 31, the pressure applied to the safety pedal 31 is larger than the pressure set value of the gravity safety trigger switch 32, the gravity safety trigger switch 32 can be actuated, the pressure relief solenoid valve is electrified, oil leakage of an oil supply pipeline for hoisting hydraulic operation is caused, and the hoisting operation cannot be continued. If the operator intends to continue the lifting operation, he must sit back on the operating seat 11, thereby avoiding the risk of the operator falling from the car body 12 and ensuring safety.
