Passanger  elevator parts load cell
EWD-H-XJ3 Elevator Load Weighing Device

INTRODTION MANUAL

l This system is applicable to all elevators with movable platform car (containing 3-channel programmable switch signals)

l Main characters:

1. Contactless inductive working mode, With no mechanical movement,no need to fix the original position of elevator overload switch, and to change structure of elevator platform car.

2. Electrical properties is in compliance with the standard of the International Electro-technical Commission.

3. Set up all parameters on the spot.

4. Adopt strong inductive magnet, improve the anti-interference ability to the utmost.

5. System carry scientifical computing out according to mathematical equations to automatically amend detention of error. It also has no-load auto zero capacity.

6. It is totally convenient to adjust on the pot by means of artificial self-study or artificial displacement.

7. Signal created by ourself control method of programmable output signal created by ourself is applicable to all kinds of traction elevator with movable platform car.

8. Integrated structure design: small size, easy installation.

Installation Instruction

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 floors are built to use the construction elevator? With six floors?
No ~ there is no hard and fast rule, you need to choose from the construction, main consideration cost
Q:What about the energy efficiency of the escalator
Construction elevator adopts frequency conversion stepless speed, smooth braking, small impact on the grid, and energy saving effect is obvious, ordinary construction elevator running speed is 36 m/min, motor, 3 * 11 kw; Frequency conversion construction elevator running speed can reach at low speed: 0-46 m/min, motor: 2 * 11 kw, whether in theory or in practical construction, energy saving effect is remarkable, some developed coastal areas in frequency conversion construction elevator as mainstream products has become a trend.
Q:How do construction suspension scaffolding be handled in the people's elevator?
You need to transfer at the scaffold poling build-up on the cantilever beams, and one cargo lift scaffolding and scaffolding disconnect processing, so that not only is the stress problem, and is an outer layer removed, people transfer the general is still there, easy to keep people transfer at the shelf.
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:Why is the construction elevator not so close to the structure?
The country stipulates that the distance between the moving parts of the elevator and the building and the fixed construction equipment should not be less than 0.25 meters. It's mainly about safety.
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:Safety device for construction elevator
When the cage is in an emergency for various reasons during the operation, the driver can press the stop switch at any time, making the cage stop running. The fast stop must be a non-self-restoring safety device, usually installed in the top of the cageConstruction lifter lifting door, protective enclosure door are equipped with electric interlock switch, which can effectively prevent because of hoisting cage or protective enclosure door open it up and running and materials caused by falling, only when the hoisting cage door and protective enclosure fully closed to start running.
Q:6 layer of brick and concrete construction project, have tower crane still need construction elevator?
6 floors of brick and concrete construction projects, tower cranes do not need construction elevator. Brick structure refers to the building of the wall of vertical bearing structure, column, etc. By using brick or block masonry, lateral load-bearing beam, reinforced concrete structure is adopted for floor, roof boarding, etc. In other words, the masonry structure is a small amount of reinforced concrete and most brick wall bearing structures. The masonry structure is a kind of hybrid structure, which is composed of brick wall and reinforced concrete beams. Suitable for small width and depth, room area is small, multilayer or low-rise buildings, for load bearing walls can't change, while the frame structure of wall body can be altered.
Q:Do the elevator need to be installed when the main project is in construction
The top brass usually need to install the construction elevator.
Q:Construction site construction elevator and tower crane, which unit security check and acceptance?
The inspection, inspection, inspection and acceptance of the inspection station shall not be put into operation
