Building Hoist Single SC270 Middle Speed
The driving board connects driving unit with driving frame. A rack wheel is installed at its back. Through adjusting the eccentric locking collar of the rack wheel, the clearance between the pinion and the rack can be adjusted to ensure the proper engagement of them( Before leaving our factory, the clearance between the pinion and the rack has been properly adjusted by our engineers), as a result, the cage will run more stable. The connection between the driving board and the driving frame is of float connection, with rubber shim, to reduce mechanical vibration .
The driving frame, bearing all the loading from the cage, is welded with channel steel & steel board and equipped with 6 rollers Inside the roller there is installed eccentric axle and rolling bearing, which can be adjusted separately. The adjustment of eccentric axle will effect the relative position of driving frame and mast. The safety hook is installed on the driving frame, aiming to avoid overturn of the driving frame and disengagement position between pinion and rack. The driving system, as the vital part of the hoist, is composed of the electrical magnetic motors, reducers and driving frame.
Main Parts of Building Hoist
1. Adopts the most advanced VF speed control device and microcomputer programmable logic controller.
2. Stepless speed control helps eliminate the concussion during start up and braking, steady the operation process, and ensures automated leveling.
3. Adopts open loop V/Fcontrol; the speed control precision can reach ±2~3%. Realizes accurate low speed positioning of the hoist and avoid slipping during downward stopping of hoist.
4. The VF system has current-restriction function, ensuring a small current when motor start up and reducing the concussion to power supply. It reduces the engery consumption and mitigates effects to on site electric equipments.
5. The steadiness during running mitigates concussion to mechanical parts, reduces wears of rack, pinion and the brake and prolongs the spare parts'life.
6. The VF system also has the over voltage protection,low voltage protection, overcurrent, overload and anti-stalling protection functions,
7. The system applies the special software for hoists developed by our company, making the operation more safe and reliable.

FAQ of Building Hoist
Q: What is the building hoist main purpose?
A: Building hoist equipped with double or single cabin to transport the materials and labors up and down. It's the ideal construction equipment for vertical transportation in the field of construction.
Q: What is the main structure of building hoist?
A: The P/M construction hoist mainly contains metal structure, driving system, electrical control system, cable guide & protection system, electrical top crane and safety device.
Q: What is the meaning of the building hoist’s code?
A: Take SC200/200 for example: “SC” stands for rack and pinion hoist, “200/200” stands for double cage and capacity is 2 tons per cage. “SC200” stands for single cage and capacity is 2 tons.
Q: What is the dimension of the cage?
A: Normally the cage dimension is 3X1.5X2.5M (L/W/H) for 2t type hoist. Details should be checked according to our quotation sheet. Also, the size can be customized according to the factual site condition. There are two doors (entrance & exit doors) for each cage, It can be produced as up & down sliding or ramping model for safety and convenience.
