WinnerLifting makes slings for years,especially for the polyester flat webbing slings.
Not limited to European countries,we also provide slings for America and many other countries.
You can find slings of different safety factors here,like 4:1,5:1,6:1,7:1 even the one especially for Australian market--8:1.
Plus,usually our slings have different colors distinguished by its lifting capacity,however there are also the single yellow color with red lines in the middle for the American market.
Let's see what WinnerLifting could bring to you!

It is understood that equal-wall thick screw pumps are widely used in the oil field as a high-efficiency machining equipment. However, in the manufacturing process, how to uniformly inject 6 mm thick rubber into the inside of a pump tube with a diameter of 10 cm and a length of more than 7 meters has been a problem.
In response to this problem, good news came from Qingdao University of Science and Technology. The associate professor Zong Dianrui led the team to develop a low-temperature continuous extrusion process and a LCE108-type screw pump rubber stator molding unit that took 5 years to allow continuous extrusion and injection molding and vulcanization molding to be performed on the same equipment. The equal wall thickness stator screw pump manufactured by this technology has now entered the stage of industrialization.
When this low-temperature continuous extrusion process is applied to the production of large-scale engineering rubber products, it has better performance than ordinary rubber injection machines. It overcomes the intermittent production restrictions of ordinary injection molding machines and vulcanizing cans, and allows extrusion plasticization, injection molding, and vulcanization molding to be continuously performed on the same equipment, thus creating the “intermittent production of large-scale polymer injection productsâ€. "Continuous production" of the new mode of production.
According to reports, the equal wall thickness stator screw pump is produced using this equipment and technology, which makes up for the shortcomings of the conventional screw pump stator technology and improves the downhole pump efficiency. It has been applied in many companies.
