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: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: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:Is the elevator detail a construction plan? Do you have a detailed picture of the elevator?
The construction diagram of the elevator appears to be a qualified elevator construction unit
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 working principle of construction elevator
How the elevator works: The main bearing structure is self-formed system, which is low on construction. 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.
Q:The staff on the construction platform shall not exceed the number of people
Different models have different load rating and platform lift platform size, this depends, suzhou new aluminium alloy elevator, Lin professional aluminum alloy lift platform.
Q:Safe use of construction elevator
1, seek professional installation. 2, pay attention to safety when using, don't worry, because the elevator is not as fast as the elevator. 3, if there is a broken part, change it quickly, don't delay and feel free
Q:Can construction elevators be taken by people or by goods
?yes, you can! It is to pass the authority authority to issue use card to be able to use! Construction lifts are also called elevators
Q:The construction elevator can not operate during the use of several stages of wind power
11, when the wind speed exceeds 20m/s and the bad weather, such as hail, not use the lift." I'm a construction elevator This is the norm It's about a six-stage wind by 20m/s.
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.
