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: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:What is the main function of the construction elevator safety guard
Falling to a certain speed will automatically card death
Q:Safe use of construction elevator
In the case of passenger and carriage, the loading shall be uniformly distributed, and the overload shall be strictly prohibited. When the elevator runs to the top and lowest levels, it is strictly forbidden to stop at the collision or lower limit. 7. The driver for leaving hanging basket and while going off work, should be hanging basket fell to the ground, to cut off the total power supply, and the door is locked point, prevent other undocumented workers start the hoisting cage without authorization. Wind up above 6, should stop using the elevator and bring the cage down to the ground. There must be good protection on both sides of the transportation channel. Floor door should be in a normally closed state, its height should conform to the requirements of the specification, anyone shall not open or head out of the door, when the floor door open, the driver shall not start the elevator. Ensure that the communication device is in good condition and the driver should be able to start the lift after confirming the signal. The driver should immediately execute any emergency stop signal on the floor of the operation. The elevator should be installed on a separate ground protection and lightning protection device. It is strictly forbidden to do maintenance work under the condition of the elevator. If maintenance is required, the power supply must be cut off and the sign of "check in, shut off" will be hung in a prominent place.
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 elevator can only go up can't come down what happened
Does the motor have electricity when it falls? Look at the switch and the line first, then check the controller.
Q:What is the main function of elevator motherboard?
A control system includes light, machine, electric, calculate, calculate the mainboard is mainly responsible for, the equivalent of the human brain, it gathers the elevator running status, corresponding analog signal output, control of elevator running properly and safely.
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.
Q:What are the requirements for the construction elevator
The anti-drop safety device is an important part of the construction elevator, which can be relied on to eliminate the occurrence of the fall accident and guarantee the safety of the crew. So for safety device factory test is very strict, before delivery by the statutory inspection unit for torque measurement, critical speed measurement, measuring the amount of spring compression, each with the test report, after assembly to the construction lifter for drop test under rated load, and the site to use the elevator must be every three months to conduct a drop test. For safety device to the factory for two years for safety device (delivery date), must also be sent to the statutory inspection unit to carry on the test, after testing once a year. So far few inspection, some sites even once every three months to detect don't do drop test, all think that their is no problem for safety device, but once had an accident, repent at leisure. Why not do regular tests and tests? The use of units blindly thinks that not bad is good. Actually good or bad for safety device can only judge by test and inspection in the daily operation is not sure whether it is good or bad, for those who are serving for safety device, or advice for the earlier inspection and regular test, only accomplish know fairly well, to malignant accident prevention rather than cure.
Q:The calculation of the use of electricity in the construction elevator
Try using the security software. There is a cracked version
Q:How does the construction lift fall without electricity
The lockers are finished with the report, unless there is a problem
