Main Parts of Building Hoist 


● Adopts the most advanced VF (Siemens, Schineider, Yaskawa) speed control device and microcomputer programmable logic controller.

 

● China famoust brand motor and Nord motor are both available


 

● 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.

 

● Standard cage size is 3.2x2.5x1.5m, customized cage size can be met.   

 

● Lifting speed can be divided into three level low, medium and high. The speed selection depends on the height of building.


● The system applies the special software for hoists developed by our company, making the operation more safe and 

reliable.

Q:Is the construction elevator a special equipment
The construction elevator is a special equipment. Special equipment is related to life safety, greater danger of boilers, pressure vessels (including gas cylinders), pressure pipes, elevators, lifting machinery, passenger ropeway, large-scale amusement facilities and field special motor vehicles (factory) in these eight types of equipment. In order to guarantee the safe operation of the special equipment, the state of all kinds of special equipment, in three stages: from the production, use, the examination has strict rules, is a whole process supervision. According to a 2013-2017 China special equipment inspection testing industry market foresight strategic planning and investment analysis report statistics, by the end of 2011, the national special equipment comprehensive inspection agency has reached 545, including quality inspection department inspection institutions, industry inspection institutions and enterprises self-checking, in addition to type testing institutions, nondestructive testing institutions, cylinder inspection institutions, etc.
Q:How many kw is the sc construction elevator
There is no fixed standard, which is widely adopted, 3X11KW, which is 33 kilowatts. The power of the motor is determined by the speed ratio of the decelerator. The most common lifter is 33 kilowatt, the speed ratio 1:16, 33 meters per minute.
Q:The maximum allowable deviation of the vertical is the vertical degree when the construction elevator is installed
5 kinds of circumstances. 1: the height of the elevator guide frame is less than 70 meters, and the vertical deviation should not be greater than one in 1000 of the height of the guide frame. (assuming the rail frame is 70 meters high, the deviation cannot be greater than 70mm) 2: the rail frame is greater than 70 meters and is less than 100 meters, and the deviation is less than or equal to 70 mm. 3: the guide frame is larger than 100 meters and is less than 150 meters. The deviation is less than or equal to 90 mm. 4: the guide frame is larger than 150 meters is less than or equal to 200 meters. The deviation is less than or equal to 110 mm. 5: the guide frame is greater than 200 meters, and the deviation is less than 130 mm. This is based on the requirement of 5.2.2.1 from GB10054 to 2005. (it used to be a direct copy.)
Q:Safe use of construction elevator
In the case of passenger and carriage, the loading shall be uniformly distributed, and the overload shall be strictly prohibited.

Wind up above 6, should stop using the elevator and bring the cage down to the ground. There must be good protection on both sides of the transportation channel. Floor door should be in a normally closed state, its height should conform to the requirements of the specification, anyone shall not open or head out of the door, when the floor door open, the driver shall not start the elevator. Ensure that the communication device is in good condition and the driver should be able to start the lift after confirming the signal. The driver should immediately execute any emergency stop signal on the floor of the operation. The elevator should be installed on a separate ground protection and lightning protection device.

Another 9 meters per wall, the most suitable installation time is a building at least 12 meters, which can be installed at 21 meters in the evening.
Q:What is the safety device for construction elevator?
Safety guard, safety hook, safety switch (limit switch, limit switch, break cord switch), braking system, overload protection device etc.
Q:The construction elevator always jumps
