The invention discloses an electric trolley. The electric trolley comprises a chassis, an anti-collision unit and a brake disc arranged on a rear wheel axle. The anti-collision unit is arranged on the bottom side of the chassis and is configured to complete locking of the brake disc in the process that the anti-collision unit makes contact with a collision object and continuously gets close to the collision object, and therefore anti-collision of the electric trolley is achieved. When the electric trolley is accidentally started due to improper operation in a construction elevator, the trolley collides with the wall surface of the elevator at a high movement speed, and at the moment, the collision rod is in contact with the wall surface of the elevator preferentially and triggers a braking system of the device, so that the trolley is decelerated and stopped, and a certain buffering effect can be achieved. And meanwhile, a part of kinetic energy is converted into potential energy of the device, so that the impact force on the wall surface of the elevator is greatly reduced, and the carrying operation of the electric vehicle in the construction elevator is effectively ensured.

    本发明公开了一种电动手推车,所述电动手推车包括底盘、防撞单元以及设置于后车轮轴上的刹车盘;所述防撞单元设置于所述底盘的底侧,并被配置为当防撞单元与碰撞物接触并持续靠近的过程中完成对刹车盘的锁死,从而实现电动手推车的防撞。本发明电动手推车在施工电梯中因不当操作发生意外启动时,手推车以较高的运动速度撞向电梯墙面,此时碰撞杆优先与电梯墙面接触并触动装置刹车系统,使手推车减速并停止,能起到一定的缓冲作用。同时,将一部分动能转化为装置的势能,极大地减小了对电梯墙面的冲击力,有效地保证了施工电梯内电动车的运载作业。
