Product Description:

900ttransportation and erection integrated machine adopts a three-pronged designingmode with elevation, transportation and erection. It is used to transport anderect prestressed reinforced box girders of 32m, 24m, and 20m (if necessary, itcan also erect non-standard box girders between 20 and 32m) in the high-speedrailway and passenger line. It can pass the hole with the whole set of boxgirders through the tunnel of 250km/h our 350km/h. It can erect girders attunnel portal or even inside the tunnel, the method of which is the same withtasks without tunnels. It can move and erect on the normal pavement, roadbed orfinished box girders without damning anything. It can erect girder on either sideof the girder yard without the problem of transferring sites. Compared withpresent launching girder, it can erect the beam smoothly without the auxiliarymachine, which is of less weight, simple form, needless to be anchored, easyoperation and high efficiency; easy operation in the entire machine’s spantransformation, and has a stronger adaptability for the operating conditions.

Accordingto different mechanical structures, there are 900t Single-beam TransportationAnd Erection Integrated Machine and 900t Double-beam Transportation AndErection Integrated Machine.

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 working principle of construction elevator
The construction elevator is a kind of common name, its standard name should be the construction elevator, this is a kind of crane machine equipment. Construction lifter adopts modular structure, because it is used in construction process, the elevator needs to be constantly shift with the construction project, therefore its structure must be easy to disassembly and assembly. For example, after the site is used, the elevator is disintegrated and transported to another site for reassembly of construction elevators. So how does the construction elevator work? The construction elevator mainly carries the structural self-forming system, and the construction dependence is low. It more driven by force, drive devices are installed on the hanging basket, through the gear and rack drive system, the mutual cooperation, so as to realize the rise and fall of the elevator. You may have seen gear and rack in the mechanical clock, the gear is round, the rack is straight, and the two bite together to achieve the motion. The elevator work that is common in our residential and commercial buildings is different from the construction elevator. Most of the elevator parts are fixed in buildings, which are mainly carried by buildings. Its movement is achieved through wire rope.
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:Is there a specification requirement for the floor door of the elevator to the floor? How high
The door locks must be in the direction of the elevator, and the people on the floor are not allowed to move at will, only the driver will be able to move. The other is that the height of the door must be 1.8 meters high, so that the workers' heads don't reach out to the danger.
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:The construction elevator can only go up can't come down what happened
It hasn't risen yet, how it has fallen! Is it a brain teaser?
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:Whether the construction elevator is a dual-purpose elevator
Very simple check, the construction elevator is in the construction site, not completely closed, and the human cargo is used commonly in the mall and the factory, is completely closed.
Q:Why is the construction elevator open on one side and the other on the other
Open the door, commonly known as the feed door, usually open up, and add weights to both sides. Only if the construction ladder stops at the bottom. If the door is double open, the room must be left with half a door (> 1.3 m) to open the door completely. If it is a single open door that opens up, you can save space in the cage. Double door, namely, two doors, either up or down, the two doors balance weight. It usually arrives on the required floor. There is enough room for double doors.
Q:The calculation of the use of electricity in the construction elevator
Try using the security software. There is a cracked version
