SSD serieshoist is one of main products of ours, which includes a single guider system and double cages. Every cage is an independent system, which can operate independently. The cage operates up and down along the guider system by the dragged-reply transmission of the wire-rope, which is droved, the motor in frequency speed. The transmission system composed by motor, electromagnetic brake, helical gears reducer, dragged-reply gears, and so on. The transmission should be installed on the top of the guide system, operation of which implements by the meshing of the dragged-reply gears, friction transmission of the wire-rope, and the cages and accessorys relative up and down operation. The guider system consists of many standard guiders linking together in high-strength bolts. Its frame is a 710mm×710mm and 1508mm weight frame. Compare with SS product, this product is obviously more conserving energy. This kind product applies to vertically transport staff and materials in projects construction and maintenance like: high-rise building, bridge, power plant, TV tower, and so on. It attaches to wall in indirect way or direct way. It can be used in projects construction and maintenance.
