The invention discloses a heavy object carrying device for construction, relates to the field of construction tools, and solves the problem of risk existing in start of an electric power-assisted cartin the prior art. Technical key points are that: the device comprises a hopper, wheel damping apparatuses are connected to two sides below the hopper, handlebars are arranged on the hopper, a secondwheel and a driving motor are arranged below one end, close to the handlebars, of the hopper, the driving motor is connected to the second wheel through a two-stage gearbox capable of changing a transmission ratio, a driving lever used for changing the transmission ratio of the two-stage gearbox is arranged on the two-stage gearbox, a handlebar switch used for controlling the start of the drivingmotor is further arranged on the handlebars, a storage battery is further arranged in the hopper, and the driving motor, the handlebar switch and the storage battery are electrically connected; by arranging the two-stage reduction gearbox, when the driving motor starts, the hopper can be started at a low speed, so that the hopper is prevented from being disengaged, and the safety performance of the electric hopper is improved.

    本发明公开了一种建筑用重物搬运装置,涉及建筑工具领域,解决了现有技术中电助力推车启动时存在危险性的问题,其技术要点是:包括料斗,料斗的下方两侧连接有车轮减震装置,料斗上设有车把,料斗靠近车把的一端下方设有第二车轮和驱动电机,驱动电机通过能够改变传动比的二级变速箱连接到第二车轮上,二级变速箱上设有用于改变二级变速箱的传动比的拨杆,车把上还设有控制驱动电机启动的车把开关,料斗内还设有蓄电池,驱动电机、车把开关和蓄电池电性连接;本发明通过设置二级减速箱使得启动电机启动时,料斗能够以较小的速度启动,从而防止料斗脱离,提高了电动料斗的安全性能。
