Main Parts of Building Hoist
● Adopts the most advanced VF speed control device and microcomputer programmable logic controller.
● Stepless speed control helps eliminate the concussion during start up and braking, steady the operation process,
and ensures automated leveling.
● 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.
● 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.
● The steadiness during running mitigates concussion to mechanical parts, reduces wears of rack, pinion and the brake
and prolongs the spare parts'life.
● The VF system also has the over voltage protection,low voltage protection, overcurrent, overload and anti-stalling protection functions,
● 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.
- Q:How much cable does the construction elevator 44KVA need?
- 44 kva should choose 16 + 2 * 3 * 6 square cable, 16 of the 30 ℃ safe carrying capacity is 78 a cable Current I = P/U / 1.732 = 44000/380/1.732 is approximately 67A The construction elevator will not only carry the engineering materials but also the higher frequency, the load calculation will be calculated according to the continuous working system. The cable should be used for the YGTZ special cable.
- Q:Why is the construction elevator open on one side and the other on the other
- Double door is feeding door, double door to the outside of the other's role is to prevent someone broke into the cage after elevator start circle accident, because outside over the door of the cage has a travel switch, when someone will ring into the cage opened the cage door, travel switch action at this moment, the elevator power cuts, you won't get elevator lay down this kind of thing. The door is open only when the lift is off the ground, as is said upstairs.
- Q:6 layer of brick and concrete construction project, have tower crane still need construction elevator?
- Tower crane is used for heavy lifting, long pieces, small machinery and materials must be used in the construction elevator.
- Q:What are the requirements for the construction elevator
- So for safety device factory test is very strict, before delivery by the statutory inspection unit for torque measurement, critical speed measurement, measuring the amount of spring compression, each with the test report, after assembly to the construction lifter for drop test under rated load, and the site to use the elevator must be every three months to conduct a drop test. For safety device to the factory for two years for safety device (delivery date), must also be sent to the statutory inspection unit to carry on the test, after testing once a year.
- Q:Does the new approach builder need a localizer test report
- Need, not for safety device testing qualified report, inspection agency will not issue the inspection report, in the construction of elevator installation supervision and inspection report, there is a specifically for, for safety device must have testing qualified report, to be certified.
- Q:How many guides are in the construction elevator
- 1 guide frame is 1508cm, the highest can be 400 meters
- Q:There are two 18-story buildings under construction and tower cranes.
- In this case, you do not need to install the construction elevator at the main stage. After the main body is finished, install the tower crane, reinstall, mainly for decorate the vertical transport of the stage.
- Q:A lift motor is 7.5 KW, and the frequency converter sends current 4.2 A, which has A heating resistance in the converter, and how the charge is calculated when the lift is full. Or consider the power of the converter and the power of the thermal resistance.
- Use electricity in the field (1) lifting equipment class: tower crane 2, construction elevator 3; According to the table, K = 0.3 cos phi = 0.7 tg phi = 1.02 JC = 40% (temporary load) Pe = 2 times 63 + 3 times 11 = 159 (kW) And then power: PS = 2 times Pe = 2 times 159 = 201 (kW) Pjs1 = K * PS = 0.3 * 201 = 60.3 (kW) Qjs1 = tg phi by Pjs1 = 1.02 times 60.3 = 61.5 (kVA)
- Q:The working principle of construction elevator
- How the elevator works: The main bearing structure is self-formed system, which is low on construction. It more driven by force, drive devices are installed on the hanging basket, through the gear and rack drive system, the mutual cooperation, so as to realize the rise and fall of the elevator.
- Q:The difference between the derrick and the construction elevator?
- Derrick is with the hoist rope hoisting, referred to as goods for SSB100 type, with construction lifter model does not allow the manned, deadweight is one tons, construction lifter is said cargo amphibious ladder, with gear and rack driving, weight is 2 tons, you can have a look at the GB/T 10054-2005, the construction lifter, with clear rules.
