Product Description:
Ship building gantry crane is a kind of great lifting capacity, large span, high lifting altitude, multi-function, high efficiency of gantry crane, is special for the fragmented transport, end-to-end joint and turning operation of large ship hulls. Ship building gantry crane is used in the place of manufacturing of ship and dock.
In the past ten years, with the development of large-scale ship building, Shipyard gantry crane for sale, ship building gantry crane is the rapid growth of demand. Compared with the traditional portal crane, large ship building gantry crane has the obvious advantage of the installation and transportation of hull sections. It spans the dock (berth), can provide on-site assembly service at the coverage plane in the dock, not only has the lifting, horizontal transport function, but also can implement hull air turnover, adjusting the fragment to the welding position of ship required.
Features:
1. It have multiple functions of single hanging, hoisting, turnover in the air, slight horizontal turnover in the air and so on;
2. The gantry falls into two categories: single girder and double girder. To rationally utilize materials, the girder adopts optimum design of variable section;
3. The gantry rigid legs with a single column and double column type for customer choice.
4. The upper trolley has two main hooks, which are separately fixed at both sides of the main beam, but the lateral movement can be individually or simultaneously 0 - 2m.
5. The lower trolley has a main hook and auxiliary hook, which fixed below at the center of the two girders;
6. Both the upper trolley and the lower trolley can cross each other for operation;
7. All the lifting mechanism and travelling mechanism adopts frequency conversion speed regulating;
8, On the top of the girder at the side of rigid leg is equipped a jib crane to accomplish maintenance of upper and lower trolley;
9. In order to prevent the storm attack, such safe and reliable anti-wind devices as rail clamp and ground anchor are equipped.

- Q:Is the construction elevator the same as 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 1-5 tons, running speed is 1 to 60 m/min.
- Q:Construction elevator positioning should consider which problems
- First make sure that the whole fence can be put down, and there should be no other extension of the fence that does not interfere with the lifting up and down of the cage Considering the length of the wall support, ensure the effective adjustment of the enclosed wall Then consider the installation of the wall support Consider whether access to the building is appropriate Some sites have been put into buildings directly, and some sites have considered scaffolding between them
- Q:For example, what records do you want to have a third party monitoring?
- Important parts replacement needs to be changed to the qualification, the procedure is like the new ladder, according to the new ladder standard test.
- Q:Where is the location of the elevator in the project
- Hard to answer, I think should combine the construction plan, adjacent to roadway facilitate material transport, and combining with the construction progress, do not put in sample area, in addition to combined with the construction interface classification and so on into consideration, to say.
- Q:The construction of more than many floors must be used for construction elevators
- The construction elevator, the average layer height above 12 floors need to be used, the hoist machine is not to go up to use the construction elevator to send a person to carry a few light things upstairs. Pre-installation preparation: After construction, the manufacturer will show the product certificate and provide the instruction manual. According to the technical requirement of installation safety technology checking list according to the construction elevator, the preparation should be inspected. The installation operator should hold the certificate, accept the technical, safety, etc., and make the safety operation rules for the construction lifter. 3, work environment: 1) the power supply must meet the requirement of power supply. 2) no electricity, gas welding or other obstacles to the operation of the crane are prohibited within the part of the elevator installations. 3) the platforms and channels that enter the building from the suspended cage shall reach the bearing capacity of more than two tons, and have strong protective barriers and protective doors. 4) it is forbidden to use guide rack, attached part scaffold, construction platform and the floor channel stretch, pipeline, rope, rope, banners, flags and other things has nothing to do with the elevator; In the evening homework, there should be sufficient illumination. 6) the doors to the floor will be kept in the door, each with a clear sign of the floor number.
- Q:Gear rack driven
- 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:Is the construction elevator a special equipment
- Belong to special equipment construction lifter, but generally used as home building municipal engineering does not belong to the quality and technical supervision management, but belong to the administration of urban construction. Because the system of quality control unless invited, shall not be involved in military, aerospace, nuclear industry, mine, municipal, sea, railway locomotive hoisting machinery management.
- Q:How many kw is the sc construction elevator
- There is no fixed standard, which is widely adopted, 3X11KW, which is 33 kilowatts. The power of the motor is determined by the speed ratio of the decelerator. The most common lifter is 33 kilowatt, the speed ratio 1:16, 33 meters per minute.
- Q:Should a fire extinguisher be equipped in the construction elevator?
- The dual-purpose construction elevator should be needed
- Q:When does the construction elevator take off?
- If the elevator is installed later, can the construction elevator be demolished at this time? It should not be removed because the elevator is used by the local technical supervision bureau. The unused elevator will be fined 5-200, 000 fine and the elevator installation unit will be revoked. No one will take that risk! It is usually done on rooftops, indoors and outdoors, and the materials have been transported upstairs. It is best to be able to remove the elevator when it is finished, so it doesn't affect the progress.
