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: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:What is the meaning of double straps in the construction elevator?
- One component of the elevator's drag system is the weight of the car. The other side of the car is connected to the top of the car by dragging a wire rope. It can be used for the energy saving of the elevator towing system, because the elevator load optimization is calculated by the theory calculation. The elevator should be calculated before the weight is weighed: the calculation principle is that the weight is equal to the weight of the car and half the load.
- 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. When the elevator runs to the top and lowest levels, it is strictly forbidden to stop at the collision or lower limit. 7. The driver for leaving hanging basket and while going off work, should be hanging basket fell to the ground, to cut off the total power supply, and the door is locked point, prevent other undocumented workers start the hoisting cage without authorization. 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. It is strictly forbidden to do maintenance work under the condition of the elevator. If maintenance is required, the power supply must be cut off and the sign of "check in, shut off" will be hung in a prominent place.
- Q:How many people are there for construction workers
- The elevator is a vertical elevator with electric motors, which is equipped with box pods for multi-storey building and carrying goods. There is also a terrace, which is running continuously on the crawler, commonly known as escalator or automatic walkway. A fixed lifting device for the floor. Vertical elevator has a car, running on at least two columns of the vertical or Angle is less than 15 ° between the rigidity of rail. The size and structure of the car is convenient for passengers to enter or unload cargo. Traditionally, the elevator is the general term for vertical transportation in buildings, no matter how they are driven. Speed can be divided into low speed elevator (1 m/s), rapid elevator (1 ~ 2 m/s) and high speed elevator (2 m/s). Hydraulic elevators were introduced in the mid-19th century and are still being used in low-rise buildings. In 1852, the United States developed a safety elevator for wire rope lifting. In the 1980s, there was further improvement in drivers, such as the electric motors, which were driven by worm gears to turn the winding drum and balance weight. At the end of the 19th century, the friction wheel drive greatly increased the lift height.
- Q:How much cable does the construction elevator 44KVA need?
- 44 kva? What elevator, convert the high piezoelectric 44kva to power 35.2 KW, current 80A16 square cable
- Q:The elevator is banned from using elevators for more than a class of high winds
- According to the safety requirement is level 6, please adopt!
- 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:Construction elevator positioning should consider which problems
- First make sure that the whole fence can be put down, and there should be no other extension of the fence that does not interfere with the lifting up and down of the cage Considering the length of the wall support, ensure the effective adjustment of the enclosed wall Then consider the installation of the wall support Consider whether access to the building is appropriate Some sites have been put into buildings directly, and some sites have considered scaffolding between them
- Q:Why is the construction elevator not up to the roof
- The free end of the construction of the lift height is only 7.5 meters high, general construction elevator drive now is the case, so the hoisting cage height and drive around 4.5 meters high, the other national standard construction elevator ceiling limit moves, drive above about 1.8 meters away from the top of the rails. So it's the free end of the construction elevator that can't satisfy the roof. As long as they can set up effective adhesion measures, they can also get on the roof.
- Q:The difference between the derrick and the construction elevator?
- You want the picture to still want to explain, the words to go to baidu search all can. The derrick is not to be multiplied by the person, the setting height is not more than 30 meters, now most of the place begin to phase out the use of the derrick, because the safety coefficient is low. The construction elevator can carry cargo, set up a height of 150 meters, and can carry a weight of 1-3 tons
