East German brand SC200 / 200 construction elevator has a complete and reliable electrical and mechanical interlock safety device, a safety switch, upper and lower limit switches, limit switches, safety interlock switches and electrical hook protection. Advanced progressive anti-fall safety device, sensitive and reliable overload protection device and advanced computer automatic leveling device, is your best choice. Using a full set of imported frequency control system, with high-quality motor and reducer, to enhance the speed of 0 ~ 36m / min, to meet the requirements of customers. Frequency construction hoist has the following characteristics: 1. Kai smooth braking, no impact; 2. lifting speed regulation by the driver; 3. Start the flow is less than the rated flow; 4. reduce mechanical wear, due to no impact on startup, can greatly lower gears, racks and other mechanical wear, brake wear is extremely obvious decline; 5. energy saving effect is obvious. Computer automatic leveling construction lift has the following features: 1. Simple structure, the controller uses the microcontroller, using the limit switch signal input; 2. Using drop rebound docked method using hoists overcome inertia weight, the maximum deviation is less than 3 cm; 3. protection to prevent illegal operations; 4. superior robustness.
