1. As near to install this device in the bottom or the elevator the overload switch location, near the center of the system should be installed on the bearing beam of the elevator to the bottom, induction magnet adsorption in the bottom, and the marking surface of weighing device sensing point;
2. System bracket should be made on the basis of the condition of the elevator, but must use the not easy to deformation material, the better of the thickness is more than 4 mm or with stiffener, to prevent sway;
3. Adjust the device, make the bottom magnet aimed at center of end surface. At the same time must ensure that the device end face and the magnet end face parallel to each other.

- Q:The calculation of the use of electricity in the construction elevator
- 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: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: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:The construction elevator should have those procedures
- 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.
- Q:How many meters or how many layers should the construction elevator be installed?
- Construction elevator is also called construction lifter, alias outdoor elevator or people dual-purpose ladder. The country is not clear how many meters or how many layer must be used, but in some coastal developed cities are now more than 30 meters using construction elevator, some cities also issued relevant rules more than 30 meters must use construction lifter, gantry and hoist is no longer used.
- Q:How is the construction elevator installed
- The construction elevator should choose a good position first, do the elevator foundation, at the same time make the wall in the setting process. This one has the corresponding elevator basic drawing, should the professional personnel carry on setting up and disassembling.
- Q:How to save the elevator accident
- Take escalator safety knowledge Passenger escalator before to keep checking your shoes clothing habits should fasten shoelaces wear skirt drag clothing such as optimum rolled up against the edge of the elevator, comb plate drag or stuck passengers carry baggage increase the risk of escalator accident now need extra or simply choose to take the stairs Escalator self-help hair accident? Every escalator, the stop button and denier hair escalator accident near the button passenger safety awareness should be kept between the first button escalator automatic stop energy efficiency to reduce accident damage Take escalator Cheng Shen fall should use to protect themselves as to avoid the rot slip or fall high neck should hands fingers crossed by strongly impact the dangerous clasped, protect brain neck elbows forward cover bilateral temporal pour knees bending forward as far as possible to protect the chest abdominal viscera side found important discoveries escalator before the sudden fall should the horse stopped footstep simultaneous for help inform passengers will forward near the accident should maintain a stable mood calm reason for avoiding the accident hair running blind hair stampede damage
- Q:What is the main function of elevator motherboard?
- A control system includes light, machine, electric, calculate, calculate the mainboard is mainly responsible for, the equivalent of the human brain, it gathers the elevator running status, corresponding analog signal output, control of elevator running properly and safely.
- Q:How does the driver of the construction elevator do the search for a sudden power failure
- When the elevator in the operation of the midway stop due to power outages or other reasons, the manual can be decreased, 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.
- Q:The construction elevator always jumps
- The construction elevator of our construction site always jump at the start of the building, always can't find the reason, the reason that can be so, have a person encounter this thing But it used to be normal, and sometimes it's jump, start, jump, start, and sometimes you can do it over and over again,
