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:What's going on with the decline in construction lift
Check whether the brake contactor and normal, contactor adhesion conditions will decline, brake pads have the problem not only rise to fall, fall in the same slide. If the contactor is ok, you can see that there is a groove on the brake pad, and it is only replaced if the brake is not damaged, such as cracking. If it's a frequency conversion elevator, if you're down, see if the converter has any fault code, if you have a consulting manufacturer. The assumption is that the anchuan frequency converter, which may be a real SE failure, means that the timing error is not normal for controlling the contact of the receiver.
Q:There are two 18-story buildings under construction and tower cranes.
Do not have a regulation, as long as the benefit construction organization, installation does not install construction lift machine all can. It should be explained that the construction elevator has manned and pure cargo.
Q:Where is the location of the elevator in the project
Construction elevator location setting, need to take into consideration the situation of the scene and the layout of the building, should consider the following factors: To facilitate the conveyance of material transportation, choose the more spacious rooms in the layout of the floor as import and export; The outside of the elevator is as spacious as possible, with construction channels and materials. The construction materials are minimized in the floor, usually in the middle of the flat. The construction personnel are handy; Monomer building expansion joints at the junction, traffic between unit set up by the elevator capsules export operation platform is completed, so the corresponding reduced floor wall body of the reserved hole lien expansion joints
Q:The construction of more than many floors must be used for construction elevators
The average height is more than 12 stories. 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 is the construction elevator installed
The construction elevator should choose a good position first, do the elevator foundation, at the same time make the wall in the setting process. This one has the corresponding elevator basic drawing, should the professional personnel carry on setting up and disassembling.
Q:The construction elevator should have those procedures
The construction elevator is short for construction. It is an important equipment in high-rise building construction, and construction site accident hazards easily, because it can cause many major accidents, injuries in the inspection should be listed as a key to check the content.
Q:How many guides are in the construction elevator
The guideway hydraulic platform is a non-shearing hydraulic platform, which is suitable for the transport of goods between low floors. The product hydraulic system sets the emergency anti-falling, the upper and lower door interaction chain each floor and the elevating platform work mesa both can set the operation button, achieves multi-point control. The hydraulic electric appliances have optional safety configuration: emergency stop, overload alarm, deceleration adjustment block, leakage proof overload protection, etc. The product structure is strong, the load is large, the elevation is stable, the installation maintenance is convenient, is the economical and practical low floor space to replace the elevator's ideal cargo transport equipment. According to the installation environment and usage requirements of the platform, the different configuration can be selected for better use. Features: minimum height of 150-300mm, suitable for unexcavated pit, at the top without lifting, is the preferred lifting device for transporting goods between lower floors.
Q:How much cable does the construction elevator 44KVA need?
44 kva? What elevator, convert the high piezoelectric 44kva to power 35.2 KW, current 80A16 square cable
Q:How to save the elevator accident
The elevator is an important vehicle in high-rise buildings, and if a failure occurs, passengers may be trapped, falling, and other hazardous accidents. Emergency point When the elevator is not normal, the legs are slightly bent and the upper body is tilted forward to cope with the possible impact. When the elevator is suddenly stopped, don't walk out the door easily, in case the elevator suddenly starts. When trapped in an elevator, stay calm and immediately use an elevator alarm bell, a walkie-talkie or telephone to contact with the relevant personnel and wait for outside help. If the alarm doesn't work, you can call loudly or intermittently tap the elevator door. If a fire broke out on the way, the elevator should stop at the nearest floor and escape quickly from the stairs.
Q:What is the safety device for construction elevator?
Safety guard, safety hook, safety switch (limit switch, limit switch, break cord switch), braking system, overload protection device etc.
