When the movable work equipment 1000 fails, the limiting member 42 is rotated from the limiting position to the unlocking position, so that the limiting member 42 does not limit the closing cover 41, so that the closing cover 41 can be separated from the inlet and outlet, thereby making The telescopic device 22 can extend out of the accommodating space 11 for hauling work, and has a simple structure, convenient operation and strong practicability.

Further, the telescopic hauling device 100 further comprises: a folding handle 5, which is pivotally arranged on the side of the closing cover 41 away from the telescopic device 22, when the closing cover 41 closes the entrance and exit, the folding handle 5 It is suitable for being attached to the closing cover plate 41 .

That is to say, the folding handle 5 can be provided on the side of the closing cover 41 away from the accommodating space 11, and the folding handle 5 can be rotated relative to the closing cover 41. When the closing cover 41 closes the entrance and exit, the folding handle 5 can be attached to the closing cover 41. At this time, the folding handle 5 is located at the corner of the box body 1, which can prevent the folding handle 5 from hitting the object and affect the normal operation of the telescopic hauling device 100. The appearance of the equipment 1000 is more beautiful. When the movable working equipment 1000 fails, the folding handle 5 can be rotated by the staff holding the folding handle 5, so that the retractable device 22 can be pulled out of the accommodating space 11 more conveniently, and the fault can be removed.
