Superior rigidity makes the hoist dust-proof and water-pfoof; Severe environment and work condition are acceptable; Simple structure and few components Adopt Janpanese FEC chain; To greatly enhance the performance of the fatigue and wearresistance. Limit protection adevice can avoid overload occerring; Hook bolt can prevent the rigging accidently from slip; Moter is equipped with thermal protection device; limit contactors are set in the machine.

Q:What are the specifications for the rigging?
Because the demand is more difficult to buy, to ask the producer of several wire rope, please note in the purchase, purchase invoice must indicate the name of wire rope, such as phosphate coated wire rope, prevent illegal infringement of their legitimate rights and interests of enterprises, in addition, patent products are generally in the rope on the outer packing of a patent spraying mark, warranty due the main technical indicators, such as the phosphating film type and film weight (have an important impact on the weight of phosphating film size, wear resistance and corrosion resistance of the service life of the wire rope, for reference only)
Q:What does the inspection of rigging involve?
At present, the wire ropes can detect the broken wires and wear of the wire ropes and display them digitally.
Q:Types of slings for slings
Slings are mainly made of metal slings and synthetic fiber slings in two main categories.
Q:Why are the suspension bridges a main cable, even a n multi sling, not a bridge directly from the tower?
Cable-stayed bridge, also called cable-stayed bridge, is a bridge that uses many cables to directly pull the bridge on the pylon. It is a structural system composed of a pressure tower, a tensile cable and a bent beam. It can be regarded as a multi span elastically supported continuous beam instead of a pier. The utility model can reduce the bending moment in the beam body, reduce the height of the building, lighten the weight of the structure and save the material.The cable-stayed bridge is composed of pylon, main girder and stay cable.
Q:Requirements and matters needing attention in hoisting
We often encounter equipment installation, transport and installation work, whether the derrick is lifting or hoisting machinery should pay attention to the following points: (1) the indigenous construction equipment for handling mobile rolling method, the rolling rod thickness should be consistent, should buetow annual row width is 50cm long, no gloves in rollers. While loading and unloading piping shall not be greater than 20 degrees slope, raceway erection should be smooth, solid, joints staggered, the rolling speed is not too fast, when necessary to use ropes.(2) in the course of installation, if problems are found, measures should be taken in time, and then continue to be hoisted after treatment.(3) large tower equipment for hoisting derrick, hoists joint operation, the hoist hoisting speed must be roughly the same, to ensure that the tower body of each suspension force roughly uniform, avoid the tower stress uneven deformation.
Q:What's the catch?
Slings are ropes made of wire or synthetic fiber, used for hoisting.
Q:What are the installation steps for crane beams?
Installation of crane beam elevation as a negative deviation, between surface and column bracket crane beam flange into the iron plate. But the shim shall not exceed three layers and shall be placed under the end of the crane beam or under the stiffener, and the area of the shim shall not be less than 60% of the part of the contact area between the crane beam and the bracket.
Q:Is the sling the same thing as the rigging?
I have also struggled with this concept before, and I consulted the professionals specializing in rigging. I say you should be able to understand the sling, lifting heavy rigid fetching device operation means, that is to say can directly take hanging items, mainly include: grab, clamp, suction and special sling and rigging, etc.; refers to the lifting items, tie hook combination device with flexible. In the article, usually made from high strength flexible parts (steel wire rope, lifting chain, artificial fiber tape) with end ring, hook, shackle assembly.
Q:Does the pressing rope have any influence on the tension value of the wire rope?
Lifting equipment commonly used wire rope varieties of phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope.
Q:What is the influence of lifting angle on rigging?
Slings are usually steel wire ropes or chain slings. Wire ropes have manganese phosphating coating, steel wire rope, galvanized steel wire rope, manganese phosphating coating, steel wire rope is new technology product, and fatigue life is three times of smooth steel wire rope.
