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:The elevator is banned from using elevators for more than a class of high winds
More than 6 levels of wind are forbidden to be removed and used. More than 4 levels of wind are not allowed to rise, and more than 6 winds are prohibited.
Q:The construction elevator is commonly used in the process of the project
The construction elevator is commonly used in the process of the project. It is best to give a time period You're just saying one of its USES, I want to know what is the stage of what is going on in the project
Q:How many guides are in the construction elevator
A guide frame on each side of the construction elevator, which is formed by using the section of the standard section in section 1.
Q:How does the elevator operate
The application of the construction elevator has gained popularity over the years, and has attracted many employees. The construction elevator is a highly skilled industry, so it is required that the professionals must master certain expertise. Here is a knowledge of how to operate a lift machine, hoping to help you.
Q:The construction elevator can only go up can't come down what happened
Look at the contactor connectionThe drop contactor does not absorb
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 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:There are differences between the construction elevator and the construction elevator
The principle is different, the construction elevator operates in the litter box. The elevators are short for construction elevators, which are very high in the safety and performance of large facilities that can be used on the site. The construction elevator should be a dual-use lifting device.
Q:What is the meaning of double straps in the construction elevator?
One component of the elevator's drag system is the weight of the car. The other side of the car is connected to the top of the car by dragging a wire rope. It can be used for the energy saving of the elevator towing system, because the elevator load optimization is calculated by the theory calculation. The elevator should be calculated before the weight is weighed: the calculation principle is that the weight is equal to the weight of the car and half the load.
Q:Why is the construction elevator not up to the roof
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.
