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:There are differences between the construction elevator and the construction elevator: The principle is different, the construction elevator operates in the litter box. The elevators are short for construction elevators, which are very high in the safety and performance of large facilities that can be used on the site. The construction elevator should be a dual-use lifting device.

Q:6 layer of brick and concrete construction project, have tower crane still need construction elevator?: 6 floors of brick and concrete construction projects, tower cranes do not need construction elevator. Brick structure refers to the building of the wall of vertical bearing structure, column, etc. By using brick or block masonry, lateral load-bearing beam, reinforced concrete structure is adopted for floor, roof boarding, etc. In other words, the masonry structure is a small amount of reinforced concrete and most brick wall bearing structures. The masonry structure is a kind of hybrid structure, which is composed of brick wall and reinforced concrete beams. Suitable for small width and depth, room area is small, multilayer or low-rise buildings, for load bearing walls can't change, while the frame structure of wall body can be altered.

Q:Helped wall bar how to set up, and several layers of set a, two width, wall rod need a few meters long, what shape is the embedded parts, how much of a steel bar, Angle and wall vertical or have?: Direct contact with the elevator company, and they give you a plan for the construction of a pre-buried piece, and the parameters of each elevator are different,

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:How does the driver of the construction elevator do the search for a sudden power failure: When the elevator is running in an abnormal condition, it should stop immediately and take effective measures to bring the ladders down to the ground floor. When the electric is out of control in operation, the stop button should be pressed immediately. The stop button is not allowed until the failure is ruled out.

Q:Construction site construction elevator and tower crane, which unit security check and acceptance?: Inspection by the quality supervision bureau special equipment inspection department.

Q:For example, what records do you want to have a third party monitoring?: The elevator overhaul formalities; First report to the local special court, after the approval of the major repair, the major repair unit should have a major repair record to leave the record of party a, including the replacement parts or the procedure that changes. Then the local special inspection hospital will be required to check again.

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:The construction elevator is commonly used in the process of the project: Basically: completed from the main body - - complete completion

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. Note: the installation of the construction elevator is required before the installation of the local quality and technical supervision bureau. After the installation, the safety record is made in the safety record in the use of the safety record.
