Since 1955, when the first synthetic flat hoisting belt was successfully used in the industrial hoisting field in the United States, it is widely used in shipping, metallurgy, machinery, mining, petroleum, chemical, port, power, electronics, transportation, military and other fields. In particular, the synthetic fiber hoisting belt is light to carry, easy to maintain and good chemical resistance, as well as has a light weight, high strength, not easy to damage the hoisting object surface and other outstanding characteristics, it is more and more popular and has gradually replaced the steel wire rope in many aspects.
一、Polypropylene flat sling
Pickling sling is an ideal rigging in the operation. Because of its wide and flat contact surface, it is not easy to damage the sling. Due to its good acid and alkali resistance, it is suitable for hoisting paint products, plastic products, machine tools and after surface treatment of pipes, pipes and so on. The pickling sling has a wide bearing surface, which can reduce the pressure of the surface load; the pickling sling has a smooth outer surface, which will not harm the suspended object, and is portable, soft, high coefficient, long service life, and non-conductive, no electric shock hazard, good resistance to corrosion.
Principles of use:
1、Do not use damaged suspenders
2、Do not twist or twist the sling when hoisting
3、Do not tie the straps in knots when using
4、Avoid tearing the stitching joint or overworking it
5、When moving the sling, do not pull the sling
6、Avoid force or vibration caused by the load of the sling
7、Every sling in use should be carefully checked
8、Tapered fiber has a resistance to inorganic acids, but vulnerable to acid damage
9、Fibre is suitable for places where chemical resistance is possible
10、Nylon has the ability to withstand acid, prone to surface acid damage, in damp, the loss of up to 15%
11、If the sling is contaminated with chemicals or used at high temperatures, consult the supplier for advice
二、Standard flat double buckle sling
Maintenance of lifting belt:
1.The lifting belt should be placed away from heat source (flame and electric welding) or long-term sunlight and ultraviolet radiation
2.The lifting belt should be cleaned once every 3-6 months. For the use of acid and alkali occasions, should be used immediately after the use of cold water or detergent to clean the lifting belt, dry storage
3.The lifting belt should be placed on the shelf after use, should not be placed directly on the ground, to prevent the lifting belt after use mildew, rat bite, etc.
4.For damp lifting belt, to dry after preservation, to avoid damp mildew
End-of-life criteria for lifting belts:
1.Lifting belt is cut, serious abrasions, with a loose strand, local rupture, should be scrapped
2.The surface of the lifting belt is seriously worn and deformed. When the wear reaches 1/10 of the width of the original lifting belt, it should be scrapped
3.Synthetic fiber softening or aging (yellowing) , surface roughness, synthetic fiber spalling, elastic change, strength weakening should be scrapped
4.Lifting belt serious distortion, deformation, fuzzing, should be scrapped
5.Lifting belt mildew deterioration, acid and alkali burn, hot melting or scorch, loose surface in many places, corrosion, should be scrapped
6.The lifting belt with local abrasions or by Sharp Object Scratch, should be scrapped
7.Lifting belt with transverse edge cut off, should be scrapped

三、International flat ring sling
1.It can be divided into single-layer or multi-layer, and the stitching methods are various
2.The size is subject to customer requirements
3.Bearing surface width, can reduce the pressure of surface load
4.It will not harm the suspended object when lifting the object with smooth outer surface
5.Various lifting methods
6.High strength to weight ratio
7.Can be attached to anti-wear protective sleeve and anti-cutting protective sleeve
8.With labels and standard colors to distinguish the load-carrying tonnage, even if the belt wear is also easy to identify
9.Non-conductive no risk of electric shock
