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:Can construction elevators be taken by people or by goods
The construction elevator can be taken either by person or by cargo Material hoist (dragon door frame, well frame) can be carried only, not by person
Q:The construction elevator always jumps
Possible causes include: 1, the area that has broken skin in the line, leak the electric trip. There's something wrong with the switch Loose contact points in the line, and bad contact may also jump. It is best to do a thorough examination before closing the lock, and the forced closing is dangerous
Q:Why is the construction elevator open on one side and the other on the other
Double door is feeding door, double door to the outside of the other's role is to prevent someone broke into the cage after elevator start circle accident, because outside over the door of the cage has a travel switch, when someone will ring into the cage opened the cage door, travel switch action at this moment, the elevator power cuts, you won't get elevator lay down this kind of thing. The door is open only when the lift is off the ground, as is said upstairs.
Q:How is the construction elevator installed
Construction elevator installation 1) the location of the elevator depends on the condition of the site and the equipment, so as far as possible, stay away from the overhead line and keep the safe distance specified. When the elevator is running, there is a lot of danger and should be avoided. 2) the order of installation is: 3) place the chassis on the base and the base pre-buried bolt, and the platform is placed on the chassis, and the basket is placed in the middle of the chassis. 4) to install the standard section, each installation of two standard sections (usually less than 8m) to be temporarily fixed. The wire rope shall be used for the use of the temporary cable, and the joints and supporting points shall be bolted and not tied with the lead wire. 5) the installation should alternate between the two columns. Node bolt specification must according to the aperture matching, not packing, found that the aperture position at the time, can not arbitrarily expanding, more can't to lead wire bundle, instead to avoid loose node deformation. 6) when installing the standard section, pay attention to the vertical degree of the guide, and the line of the guide line should not appear in the line of folding and too big clearance to prevent the collision from running. 7) when construction site conditions permit, it can be assembled on the ground and then hoisted on the whole to reduce the height of the work. Due to the design of the frame, the stress condition of the construction is only considered, so before the whole moving up, the counter can be temporarily strengthened to enhance the bending capacity of the nodes.
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:What is the height of protecting door protection of construction elevator
Elevator protection door is strict according to the mandatory standard to set up elevator well protection measures for safety technology. The shaft must be set in the range of 1.5 to 1.8, with protective railings or fixed gate and protective railings or fixed doors. 2, elevator well in plus or minus zero layer need to set up the first safety net, every two layers, the upper part of most every 10 m AnQuanPing network design, network security quality must gb5725-1997 "safety net" of standard network, methods must be checked in accordance with the relevant provisions. Installation in the safety net elevator dismantlement, the operator should wear the seat belt according to the regulation. On the floor and roof, a short side hole is larger than 1.5 m, the hole should be set in the requirement of the protective railing, the bottom setting safety net. To set safety warning signs that meet national standards in the elevator shaft. Safety warning signs are clear, warning lights should be set at night. The protective railings and gates shall be marked with yellow and black stripes and shall be manufactured according to the standards of construction safety technical specifications. 5, elevator wellhead protection facilities need to dismantle or change temporarily, and by the project full-time safety sign shall be the responsibility of the project director, and ready to move or change the security countermeasures. To inform all staff at the same time; Recovery after safety facilities must be by the project director, full-time security personnel and other related personnel on-site inspection management, qualified rear can continue to use.
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:The tower crane is on a surface with the construction elevator, and only 2 or 3 meters away. Is that allowed
Cranes and elevators from very close, may be the reason for the sites or the position is not reasonable, so close to the distance as long as you ensure the tower crane and tower crane arm when rotating to the above the elevator after satisfying the end, must keep more than 2 meters with elevator recent distance. Or you can refer directly to the tower crane safety code, GB5144-2006.
Q:The construction elevator relies on what to carry heavy, static hour force point where
The driver of the elevator ladder cage is driven by two or three worm gear reducers, which carry heavy lifting parts, and gravity is carried by the rack. At rest, the force point is in the meshing of the gear and rack. It is the main balance between the rewire rope and the ladder cage and the relative motion. For heavy can improve dynamic performance, a heavy on the ladder cage running more smoothly, when a fall, fall of heavy can slow down the ladder cage speed, it should be said that safety performance is better.
Q:How does the construction elevator add up
The principle is simple Now, the construction of a manned, cargo-carrying construction elevator is a gear rack. You can't understand how to say that you can't understand
