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 to set up the construction elevator?
Direct contact with the elevator company, and they give you a plan for the construction of a pre-buried piece, and the parameters of each elevator are different,
Q:What procedures and procedures will be required to re-use after the construction elevator overhaul?
The elevator overhaul formalities; First report to the local special court, after the approval of the major repair, the major repair unit should have a major repair record to leave the record of party a, including the replacement parts or the procedure that changes. Then the local special inspection hospital will be required to check again.
Q:Whether the construction elevator is a dual-purpose elevator
The construction elevator is being operated on; And a person's elevator is automatically controlled; The construction elevator is directed by the rack, which is seen in the rack, and the noise is large. The escalator is not a rack, it is usually guided, and the rails are invisible. Construction elevators are rudimentary; And the elevator is complicated.
Q:The construction of more than many floors must be used for construction elevators
Elevator drivers must be trained in special safety technology, qualified for examination, and will be on duty. Strict drunken work. The driver must be familiar with the performance, construction, maintenance and maintenance of the elevator, and fill in the mechanical resume and the required reports in time. No inflammable, flammable goods and other sundries shall be piled up in the vicinity of 5m in the construction elevator, and no ditch, pits, or groove shall be dug in this area. The floor feed of the elevator should be set up for protection. When the cage is repaired, if the parts are removed and the weight of the ladder is below the weight, the ladder cage must be locked in the rail. It is strictly forbidden to use the shaft of the construction elevator to support the cable line and other items not related to the elevator. A tower crane or other lifting machine that is built on the same site shall be more than 5m above the elevator and should be properly protected against collision. After the construction elevator is installed, it must be checked and approved by the relevant personnel.
Q:How to save the elevator accident
The elevator is an important vehicle in high-rise buildings, and if a failure occurs, passengers may be trapped, falling, and other hazardous accidents. Emergency point When the elevator is not normal, the legs are slightly bent and the upper body is tilted forward to cope with the possible impact. When the elevator is suddenly stopped, don't walk out the door easily, in case the elevator suddenly starts. When trapped in an elevator, stay calm and immediately use an elevator alarm bell, a walkie-talkie or telephone to contact with the relevant personnel and wait for outside help. If the alarm doesn't work, you can call loudly or intermittently tap the elevator door. If a fire broke out on the way, the elevator should stop at the nearest floor and escape quickly from the stairs.
Q:Is there a specification requirement for the floor door of the elevator to the floor? How high
The door locks must be in the direction of the elevator, and the people on the floor are not allowed to move at will, only the driver will be able to move. The other is that the height of the door must be 1.8 meters high, so that the workers' heads don't reach out to the danger.
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:How many floors are built to use the construction elevator? With six floors?
No ~ there is no hard and fast rule, you need to choose from the construction, main consideration cost
Q:Can a construction elevator use a single cage
Seriously, a construction elevator in wuhan just happened, and 19 people died. Go and see!
Q:Can construction elevators be taken by people or by goods
The construction elevator can be taken either by person or by cargo Material hoist (dragon door frame, well frame) can be carried only, not by person
