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 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:The tower crane is on a surface with the construction elevator, and only 2 or 3 meters away. Is that allowed
Congratulations, it's a tragedy when you want to start the tower
Q:The construction elevator relies on what to carry heavy, static hour force point where
The driver of the elevator ladder cage is driven by two or three worm gear reducers, which carry heavy lifting parts, and gravity is carried by the rack. At rest, the force point is in the meshing of the gear and rack. It is the main balance between the rewire rope and the ladder cage and the relative motion. For heavy can improve dynamic performance, a heavy on the ladder cage running more smoothly, when a fall, fall of heavy can slow down the ladder cage speed, it should be said that safety performance is better.
Q:Safety device for construction elevator
1. The governor To prevent the hanging basket construction elevator overspeed or fall and set up a safety device, is divided into a unidirectional and bidirectional type two kinds, the one-way speed limiter can only along the direction hoisting cage falling within the speed limit, two-way speed limiter can up and down along the hoisting cage speed effect on two directions. The speed limit shall be tested for performance in accordance with the prescribed time limit. 2. The buffer spring Buffer spring in spring seat connected to the base frame, so that when hanging cage fall accidents, reduce the impact of the hanging basket, at the same time ensure crane cage and weight drops landed into flexible contact, slow down the hoisting cage and the impact of weight landing. The buffer spring has a cone winding spring and a cylindrical spiral spring. Usually, there are two or three cone coiled springs or four cylindrical coils on the base of each cage.
Q:The construction of more than many floors must be used for construction elevators
The average height is more than 12 stories. Construction elevators are often called construction elevators, but construction lifts include a broader definition, and construction platforms are part of the construction elevator series. Simple construction elevator is by car, driving mechanism, standard section, attached to the wall, chassis, fence, electrical system and so on several parts, manned cargo construction machinery is a frequently used in construction, because of its unique enclosure structure make it take up both comfort and safety, construction elevator is usually used with tower crane on the construction site, the average load in 1-3 tons, running speed is 1 to 60 m/min. The construction elevator of our country is more and more mature, and gradually goes to the international.
Q:Do the elevator need to be installed when the main project is in construction
In the construction of the main body, the construction elevator should be installed. The general construction is about 15 meters. The construction elevator is commonly called the construction elevator, but the construction elevator includes a broader definition and the construction platform belongs to the construction elevator series. Simple construction elevator is by car, driving mechanism, standard section, attached to the wall, chassis, fence, electrical system and so on several parts, manned cargo construction machinery is a frequently used in construction, because of its unique enclosure structure make it take up both comfort and safety, construction elevator is usually used with tower crane on the construction site, the average load in 1-3 tons, running speed is 1 to 60 m/min. The construction elevator of our country is more and more mature, and gradually goes to the international. 3, building main body engineering means based on the above foundation, accept, for all the top load and construction project, maintaining structural integrity, stability and safety of bearing structure system.
Q:How long does the construction elevator do a crash test
You don't have to do it now. Go straight to the test center. A site is tested once
Q:Should a fire extinguisher be equipped in the construction elevator?
A fire extinguisher will be required for the 500kg of manned cargo construction elevators at 500kg or more.
Q:How many guides are in the construction elevator
A guide frame on each side of the construction elevator, which is formed by using the section of the standard section in section 1.
Q:The calculation of the use of electricity in the construction elevator
The full load is 7.5 KW. The output current is 4.2 A, is the converter 7.5 KW?
