Description

Technical Field

[0001] This utility model relates to the field of logistics transfer equipment technology, and more specifically, to a manual vertical lifting door for mobile logistics equipment. Background Technology

[0002] Large flatbed trucks are also commonly used logistics transfer equipment, especially for outdoor use. Rain protection is crucial for outdoor use. Most rain protection products on the market are simply covered with a single piece of tarpaulin, which is very troublesome, time-consuming, and labor-intensive. If it rains suddenly and there is no time to cover the tarpaulin, the materials may be temporarily damaged.

[0003] Currently, the large flatbed trucks used for transporting large materials are either ordinary open-top flatbed trucks, which can only be covered with tarpaulins if it rains, which is time-consuming, labor-intensive, and very troublesome. If the tarpaulin is not covered in time, the materials will get wet and cause unnecessary losses. In the use of some existing logistics equipment with rain shelters, the doors on both sides of the rain shelter are mostly traditional double doors, which are troublesome to open and close and take up a lot of space, making them very inconvenient and inefficient during use.
