The control system functions include upper and lower limit protection, door interlock device, emergency stop button, etc., and some high-end models are also equipped with frequency conversion speed regulation function to achieve stepless speed change from 0 to 63m/min.

The safety protection system is the key refurbishment part of Dahan's second-hand lift, including the anti-fall safety device (model SAJ40-1.2), overload alarm device, rope breaking protection and emergency lowering device14. The anti-fall safety device has a speed of 1.2m/s and a rated braking load of 40kN, and all safety devices have undergone strict functional tests before the equipment leaves the factory. The car door is designed to slide up and down or ramp and is equipped with electrical and mechanical double interlocks to ensure that the equipment cannot be operated when the door is not closed.

The car system is optimized for the transport of people and is typically 3.2×1.5×2.25m (L×W×H) in size and has an internal space of 12-16 people. The cage floor is made of non-slip steel plate or glass fiber reinforced plastic grille, which has the advantages of light weight, high strength and corrosion resistance. The height of the fence meets the safety standards, and there is a protective shed at the top, surrounded by a mesh structure, which not only ensures safety but also does not affect the view. Some models of the car are hot-dip galvanized or specially anti-corrosion coating, suitable for use in high humidity or coastal areas.
