Outlook dimension installation schematic diagram
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:Can a construction elevator use a single cage
- Seriously, a construction elevator in wuhan just happened, and 19 people died. Go and see!
- Q:What about the energy efficiency of the escalator
- Variable frequency construction elevator energy saving effect general. Frequency conversion is not energy efficient. The difference between the frequency and the common machine is the smoothness and speed of the operation. Frequency conversion speeds up to 90m / 1 minutes and the average is only 35m / 1 min Frequency conversion when parking is slow down and stop Ordinary is directly stop delay parking and adjustment made door light who bow Angle decyl with brush spring connection will be better. The frequency conversion requires the site voltage to be strictly a little bit looser than the voltage requirement Energy consumption is: according to the elevator drive mechanism for general three transmission two kinds of the elevator are three 11 kw motor, that their energy consumption are 3 x 11 = 33 kw is hours each hanging basket consumes electricity 33 degrees, the actual power consumption will be bigger.
- 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
- Q:Safe use of construction elevator
- 1, seek professional installation. 2, pay attention to safety when using, don't worry, because the elevator is not as fast as the elevator. 3, if there is a broken part, change it quickly, don't delay and feel free
- Q:How many meters or how many layers should the construction elevator be installed?
- In the guangdong area, the first installation and acceptance of the equipment will be below 7 levels, and more than 7 floors will be charged for the inspection. 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:The working principle of construction elevator
- The construction elevator is a kind of common name, its standard name should be the construction elevator, this is a kind of crane machine equipment. Construction lifter adopts modular structure, because it is used in construction process, the elevator needs to be constantly shift with the construction project, therefore its structure must be easy to disassembly and assembly. For example, after the site is used, the elevator is disintegrated and transported to another site for reassembly of construction elevators. So how does the construction elevator work? The construction elevator mainly carries the structural self-forming system, and the construction dependence is low. It more driven by force, drive devices are installed on the hanging basket, through the gear and rack drive system, the mutual cooperation, so as to realize the rise and fall of the elevator. You may have seen gear and rack in the mechanical clock, the gear is round, the rack is straight, and the two bite together to achieve the motion. The elevator work that is common in our residential and commercial buildings is different from the construction elevator. Most of the elevator parts are fixed in buildings, which are mainly carried by buildings. Its movement is achieved through wire rope.
- Q:How does the construction elevator add up
- You can use a ready-made high-altitude operating platform and a high-altitude working platform
- Q:How large a leakage protector is used for the construction elevator
- If it is 33KW, direct start, single cage, 160A, leakage action current 50ma-75ma, movement time 0.1 s, electrical machine leakage protector. The best.
- Q:The maximum allowable deviation of the vertical is the vertical degree when the construction elevator is installed
- The development of the elevator is in a peak state, because most of the manufacturers or individuals to improve the utilization efficiency of space, more options for multistory buildings, which also need a device to convenient up and down by the goods. Due to the common elevator cost is high, bearing capacity is low, not suitable for carrying dozens of tons or hundreds of tons of cargo, so developed a high bearing capacity of hydraulic lift to assist in the production and transportation of goods. The elevators are both safe and super loadable, and convenient for maintenance, making the special industry grow faster.
- 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
