目前,小型工地砖的短途运输主要靠小推车。车型一般有双轮车和单轮车两种。双轮车行走平稳,装卸方便,但缺点是车轮较大,占地宽,在宿舍工程走廊上运输不便。单轮车比较灵活,但不稳,装卸时易损坏砖的边角。针对上述两种车的优缺点,我们试制了一种新的推砖车,经试用证明,使用灵活,装卸方便,每车可运砖56块,多时可 At present, the short-distance transport of small-scale construction bricks mainly depends on small carts. There are two types of models, two-wheeled and two-wheeled. The two-wheeled vehicle has smooth running and convenient loading and unloading. However, the disadvantage is that the wheels are large and occupy a large area. It is inconvenient to transport on the corridor of the dormitory project. Unicycles are more flexible but unstable, and they can easily damage the corners of bricks during loading and unloading. Aiming at the advantages and disadvantages of the two types of vehicles mentioned above, we have trial-produced a new type of push-pull vehicle, which has proved to be flexible and easy to handle. It can transport 56 bricks per vehicle and can be used for a long time.
