Description

Technical Field

[0001] The utility model belongs to the field of fire protection construction, and in particular relates to a trolley for transporting fire protection pipes. Background Art

[0002] Fire engineering construction is an important part of ensuring the safety of buildings, mainly including the installation of fire water supply pipelines and fire hydrant boxes. During the fire construction process, a large number of pipes need to be transferred to the construction site. There are no special trolleys for transporting pipes on the construction site. Pipes can only be transported by trolleys for transporting bagged and bulk building materials. The bucket of this trolley is closed on all sides and only the top is open. When this trolley transports pipes, the pipes are placed on the bucket, and the loading capacity is small. During transportation, workers need to hold the pipes by hand to prevent the pipes from shaking, and the pipes are very easy to fall from the bucket. Alternatively, cranes are used to transport pipes, but the cost of crane transportation is high. On the other hand, pipes are easy to slip off the crane hook, which poses a safety risk.
