Building Hoist Features


● 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.

Q:What is the height of protecting door protection of construction elevator
Currently tunnel door is no national standard, the only industry standards and enterprise standards, is important when choosing the tunnel door manufacturers see manufacturers have tunnel door production qualification and testing report. Formal manufacturer all have these qualifications, such as lei Chen group, tunnel protection door, explosion-proof door the qualification is very complete, you can be important consideration.
Q:What is the main function of the construction elevator safety guard
For safety device of construction hoist main effect is in the process of elevator used in times of emergency power, hit the brakes, let hoisting cage security attached on the guide rail frame, prevent the hoisting cage falling!
Q:How many years does the construction elevator usually use?
More than eight years will not give you the advice to get the factory refurbished
Q:How many people are there for construction workers
Different models of different sizes, small can multiply 10 people, this time see a big, can take 14 people
Q:Can construction elevators be taken by people or by goods
According to GB 26557-2011, "a vertical guide for people with vertical navigation". 5.6 lift cage 5.6.1 general When the maximum number of passengers can be carried, the maximum amount of the ceiling shall be calculated according to the area of 0.2 square meters per person, and the weight should be calculated at 75 kg per person.
Q:The safety officer shall be responsible for the work of the construction elevator
(1) the use of dual-use functions of the construction elevator, the installation and removal of the professional personnel issued by the competent department of construction administration shall be undertaken by the professional personnel. The personnel who have passed the training, qualified for the examination and obtained the certificate of the post shall be operated and repaired. (2) the capacity of the concrete base culture cooperation should not be less than 150kPa, the tolerance of 10mm and the drainage facility should be allowed. The distance between the guide bracket of the elevator and the wall of the building should be suitable, and the smoothness should be stable. (3) the lifter is used to control two directions, and the vertical control is 0.05%. Each floor shall have a platform, a passage, a fence and a protective door. No obstacles can be found. (4) the elevator that is installed in a dark place, and the passage shall be illuminated and a floor display lamp and floor number; A closed barrier should be set up in the well.

The lifter should undergo a fall test every three months and the fall test should be adjusted when the fall test exceeds 1.2 m. Every time it falls, the receiver should be repaired once.
Q:What is the safety device for construction elevator?
A lot of 1, anti-drop safety device 2, upper and lower limit 3, extreme limit 4, buffer spring 5, line door limit switch Single line door limit switch 7, ceiling switch 8, enclosure door lock 9, single door lock The door lock is on and off There are also many electrical safety protections
Q:How does the driver of the construction elevator do the search for a sudden power failure
There are clear rules for the safety of construction machinery (JGJ33-2001). 6.12.17 when the elevator is running in an existing abnormal condition, it should stop immediately and take effective measures to reduce the cage down to the ground level, and keep running after the failure. When the electric is out of control in operation, the stop button should be pressed immediately. The stop button is not allowed until the failure is ruled out. 6.12.20 when elevator in the operation of the midway stop due to power outages or other reasons, can be manually, the end of a motor brake electromagnet manual release slowly shake handshandle pull outward, slowly slide down the ladder cage, ladder cage fall shall not exceed the rated speed, manually drop must be conducted by professional maintenance personnel manipulation.
Q:What is the need for the sc200/200 construction elevator cable?
The sc200/200 construction elevator cable line should not be below 120 square. Man's ladder 33KW, 5 * 33 = 165KW The tower is 45KW one, 2 * 45 = 90KW The pressure slag welder is estimated to be 25KW Touch welder 1OKW, 5 * 10 = 50KW Other facilities such as mixer, temporary illumination etc. 30KW Total power: 165 + 90 + 25 + 50 + 30 = 365KW One square cable is 5 minus 7A, 380V is 1KW is equal to 2A. That's 730A 730A divided by 5-7 calculates that the cable line should not be less than 120 square.
Q:Construction elevator positioning should consider which problems
The construction elevator is short for construction. It is an important equipment in high-rise building construction, and construction site accident hazards easily, because it can cause many major accidents, injuries in the inspection should be listed as a key to check the content. Based on past accidents and on-site inspections, we often find topics that we think should be examined in a critical area
