The construction hoist (also called an external elevator, or hoist for short) is widely used for the vertical lifting and transportation of personnel and materials. In industrial or civil buildings, large bridges, and vertical shafts, it is an indispensable and excellent piece of transport equipment. As a permanent or semi-permanent installation, it can also be used in warehouses, high towers, and other different situations. Compared with other lifting mechanisms, this product has advantages such as stability, safety and reliability, no need for an additional machine room or shaft, convenient assembly and disassembly, and strong flexibility in transportation. In particular, it plays a significant role in reducing the labor intensity of construction workers, speeding up project progress, and improving work efficiency.

The SC200/200 construction hoist is a product researched and designed by Shandong Zeyu Co., Ltd. The machine has a reasonable design, a novel structure, smooth operation, complete and reliable safety devices, and convenient installation and maintenance. Its main features are as follows:

1. The transmission mechanism adopts a three-motor drive, so that the rack and pinion are evenly stressed, ensuring safe and smooth operation.

2. To ensure safe operation of the hoist, safety switches such as overload and speed-limiting switches are provided in the circuit. When the above situations occur during operation, the hoist will immediately act automatically to prevent accidents. Each door on the cage is also equipped with a limit switch; when any door is abnormally opened, the cage cannot be started or will stop immediately.

3. Each cage is equipped with an anti-fall safety device, which can very effectively prevent the cage from falling and ensure safe and reliable operation of the hoist.

4. The electrical control system of the hoist has simple circuits, is easy to operate, maintain, and service, and is reliable. During normal operation, the hoist can be operated in the cage by a handle or buttons, and it can stop at any time at any position where stopping is required. At the upper and lower terminal stations, the upper and lower terminal limit switches control automatic stopping. If the upper and lower terminal limit switches fail to work due to a fault, the final limit switch installed on the hoist can cut off the power supply in time to brake it.

5. The steel structure design has undergone scientific and rigorous calculations, meeting the requirements of a reasonable structure, reliable strength, and light weight.

6. The hoist can use the hoisting rod on the cage to install or dismantle the guide rail frame by itself. All other parts can be conveniently installed and removed, and components are also easy to replace.
