elevator  parts low cost load cell
Type ECW-P2 Elevator Load Weighing Device

INTRODTION MANUAL

This system is applicable to all elevators with movable car platform in need of overload signals. This device is of extremely high performance-price ratio. This appliance is to overcome the inherent disadvantage of the mechanical overload switch and to replace it.

Main characters:

1. Working in a contactless and inductive way. No mechanical movement itself. Being directly installed in the original place of overload switch. No necessity of changing the mechanism of elevator car.

2. Adopting strong inductive magnet, improving the anti-interference of the system to the utmost.

3. The electrical property is in compliance with the standard of the International Electro-technical Commission (IEC).

4. Rated relay dynamic open, overload relay -dynamic close and output-break are easy for customers to use.

5. More accurately positioning, small overall size, easy installation and adjustment, simple structure and low price.

Technical Specification:

Overall Size

Column of Φ24×83 mm

Working Principle:

This system weighs the elevator car load based on the principle of the elastic deformation of movable elevator car platform caused by loading with the HALL sensor measuring the change of displacement, fulfilling the aim of load weighing.

Installing Method:

Adjustment

1. Please refer to the above figure to install this device with the connecting support (made by the customer himself) closing the middle part of the car platform as near as possible.

2. Let the magnet adhesive on the car platform with the marking-face right facing the induction point of the device.

3. Install and adjust this device so that the magnet on the car platform aiming at the center point of its upper face. Meanwhile, assure the end face of this device in parallel with that of the magnet.

4. When elevator is of rated load, adjust this device up and down to make the indicator just turn green, yellow one (red one +green one) turn down , at this time, fasten this device and the adjustment is finished.  

5. At the time of overload, indicator of this device keeps yellow (green+red)

Q:The staff on the construction platform shall not exceed the number of people
Depending on the actual situation, different quality of platform specifications will affect the number of people manned. Hope can help you.
Q:Is the elevator detail a construction plan? Do you have a detailed picture of the elevator?
The construction diagram of the elevator appears to be a qualified elevator construction unit
Q:The elevator is banned from using elevators for more than a class of high winds
When the wind speed is more than 13 meters per second, the installation and disassembly is forbidden. When the wind speed exceeds 20m/s and the weather, such as hail, the elevator should not be used. This is the norm M/s is about 8, and 13m/s is about 6
Q:When building tall buildings, the machine that USES to lift concrete to wait for tall building
It should be the construction elevator. Construction elevators are often called construction elevators, but construction lifts include a broader definition, and construction platforms are part of the construction elevator series. Simple construction elevator is by car, driving mechanism, standard section, attached to the wall, chassis, fence, electrical system and so on several parts, manned cargo construction machinery is a frequently used in construction, because of its unique enclosure structure make it take up both comfort and safety, construction elevator is usually used with tower crane on the construction site, the average load in 1-3 tons, running speed is 1 to 60 m/min. The construction elevator of our country is more and more mature, and gradually goes to the international.
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 does the construction elevator add up
With the popularity of construction lifter to use, but knowledge of the user of this kind of special equipment, and makes the construction lifter in use process safety accident frequency is higher and higher, it is necessary to everyone together to discuss how to eliminate the safety hidden trouble as possible. This paper makes a concrete analysis on the use of the construction elevator during the use of the elevator.
Q:How to adjust the weight limit of the construction elevator
You're talking about a weight monitor! There are a lot of models and not a good idea.
Q:What's going on with the decline in construction lift
Check whether the brake work is valid.Check to see if there is any problem with holding the brake.
Q:Should a fire extinguisher be equipped in the construction elevator?
A fire extinguisher will be required for the 500kg of manned cargo construction elevators at 500kg or more.
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.
