Product Description:

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: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: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,
Q:How many meters must be installed in the construction elevator search?
There is an elevator quota in the budget quota, but how many floors can be priced?
Q:6 layer of brick and concrete construction project, have tower crane still need construction elevator?
Very cow! Six floors of brick and concrete construction projects have tower cranes. No construction lifts are needed.
Q:The construction elevator can not operate during the use of several stages of wind power
11, when the wind speed exceeds 20m/s and the bad weather, such as hail, not use the lift." I'm a construction elevator This is the norm It's about a six-stage wind by 20m/s.
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:How do construction suspension scaffolding be handled in the people's elevator?
The shelf of the discharge platform is separated from the outer scaffolding and set up separately! Can't connect together
Q:How many people are there for construction workers
Different models of different sizes, small can multiply 10 people, this time see a big, can take 14 people
Q:What is the need for the sc200/200 construction elevator cable?
The company now USES 3X25 + 2x10 cables
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.
