摘要： The present invention provides a hoisting device for working in heights, specifically including a vehicle body, a lower bracket installed at a bottom of a safety ladder, a host driver fixed on the lower bracket and providing lifting power, an upper bracket installed at a top of the safety ladder, a traction rope connecting the upper bracket, the vehicle body and the host driver, and a sliding rail installed on the safety ladder, and further including a fall arrester installed on the sliding rail, a guiding device assembly installed on a back portion of the vehicle body, a stall protection device installed on the vehicle body and matched with the sliding rail, a collapsible pedal installed on a lower portion of the vehicle body and configured to carry people and goods, an operation handle fixed to an upper portion of the vehicle body and a position-limiting bracket installed on an upper portion of the safety ladder. The host driver drives, trough the traction rope, the vehicle body to ascend or descend along the sliding rail, thus enabling the vehicle body to ascend or descend so as to convey people and goods. The hoisting device is simple and convenient to operate, occupies a small floor space and can be installed without changing a structure of an original safety ladder.
