A series product SCD200/200 is one kind of construction lifts that is capable of 1ton load, has two cages and attaches to wall indirectly.It includs a counter-weight system SCD200/200 is one product of our A series cnstruction lifts. A series products is one of main products of ours. SCD200/200 includes a single mast and two cages. Every cage is a independent system. It can operate independently. In the transmission system of the lift, the motor be used is three-phase asynchronous(model YZEJ132M)with brake, which is capable ofstarting stable and compensating automatically the friction gap. We also use plane three-rings enveloping worm reducer. The mast cosists of many standard sections linking together in high-strength bolts. The function of the counter-weight is that it can add the rated load. That means, for example, the rated load of SC100 that use 2motors electrical power adds a counter-weight system equals to SC200 that use 3motors electrical power. A contains : A--- Standard Provision(with a cab,no cable pulley); A1(with a cab and cable pulley); A2--(no cab and no cable pulley); A3(with cable pulley, no cab); AW----External style(it means the reducer and the motors are installed out of the cage.) < AW, A1W, A2W, A3W Based on different conditions and environments, we can provide different size products to meet your request.
