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:How to save the elevator accident
Take escalator safety knowledge Passenger escalator before to keep checking your shoes clothing habits should fasten shoelaces wear skirt drag clothing such as optimum rolled up against the edge of the elevator, comb plate drag or stuck passengers carry baggage increase the risk of escalator accident now need extra or simply choose to take the stairs Escalator self-help hair accident? Every escalator, the stop button and denier hair escalator accident near the button passenger safety awareness should be kept between the first button escalator automatic stop energy efficiency to reduce accident damage Take escalator Cheng Shen fall should use to protect themselves as to avoid the rot slip or fall high neck should hands fingers crossed by strongly impact the dangerous clasped, protect brain neck elbows forward cover bilateral temporal pour knees bending forward as far as possible to protect the chest abdominal viscera side found important discoveries escalator before the sudden fall should the horse stopped footstep simultaneous for help inform passengers will forward near the accident should maintain a stable mood calm reason for avoiding the accident hair running blind hair stampede damage
Q:The working principle of construction elevator
SC type construction lifter is a kind of elevator on the gear, rack drive, is mainly used in high-rise building construction, cargo transportation, the elevator can be very convenient to install and remove; It can increase with the increase of the building. There is a single cage and double cage construction elevator, and the single-cage construction lift can be a double cage lift after adding a cage and other parts. If a heavy device is configured, its payload can be doubled. The SC type construction elevator has a very reliable electrical and mechanical safety system, which is a safe and efficient vertical transportation.
Q:How large a leakage protector is used for the construction elevator
If it is 33KW, direct start, single cage, 160A, leakage action current 50ma-75ma, movement time 0.1 s, electrical machine leakage protector. The best.
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: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:The difference between the derrick and the construction elevator?
Derrick is with the hoist rope hoisting, referred to as goods for SSB100 type, with construction lifter model does not allow the manned, deadweight is one tons, construction lifter is said cargo amphibious ladder, with gear and rack driving, weight is 2 tons, you can have a look at the GB/T 10054-2005, the construction lifter, with clear rules.
Q:How many floors are built to use the construction elevator? With six floors?
No use on the 6th floor, use longmen well frame transportation material
Q:When building tall buildings, the machine that USES to lift concrete to wait for tall building
It should be the ground pump, the center is the tower crane, the construction face is the concrete pump of the cloth machine to the construction method. The advanced cloth machine is the arm bracket of the pump car, can operate with the remote control, is as convenient as the pump car.
Q:How does the construction elevator add up
With the popularity of construction lifter to use, but knowledge of the user of this kind of special equipment, and makes the construction lifter in use process safety accident frequency is higher and higher, it is necessary to everyone together to discuss how to eliminate the safety hidden trouble as possible. This paper makes a concrete analysis on the use of the construction elevator during the use of the elevator.
Q:How many floors do you need to install a construction elevator?
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.
