What is a trolley line? What is its classification and use?

Slippery wire is also called slide wire or slide wire. Simply put, the trolley line is a system for powering mobile devices. Mobile devices mainly refer to mobile devices such as cranes, cranes, hoisting machines, electric hoists, and elevators.

Sliding lines can be divided into TLHX single-pole trolley wires, multi-pole C-type M-type trolley wires, TLGH high-temperature steel body trolley wires, TLGJ tube-type trolley wires, and TLWJ seamless wire-sliding wire according to the use environment.

Unipolar safety conductors have a large cross-sectional area and a large amount of current, which is much larger than multipoles. The magnitude of the load current is also determined. The single-pole trolley wire is suitable for a large power crane workshop, and the multi-pole trolley wire is also used in a small power workshop.

The use of different conductor materials, unipolar slip conductor of aluminum alloy conductor, multi-polar conductor of the copper conductor, the two conductors are different, it determines the resistance of the two are different, of course, the two conductive losses are Relatively small.

At present, unipolar trolley wires are widely used, which greatly improve the degree of protection and insulation and are safe and reliable. TLHX single-pole trolley wire is mainly used for large-tonnage equipment, multi-pole trolley wire is mainly used for small-tonnage cranes, and high-temperature steel trolley wire is mainly used in places where the environment is relatively harsh, especially when it is used frequently. environment of.

EVA Marine Diamond Sheet

EVA marine diamond sheet is a new development from the EVA Faux Teak Sheet, showing a new special look from the straight grooves surface finished. Durable and shock absorbent, it provides not only an exceptional traction surface but also lessens the fatigue brought on by prolonged standing and working on hard decking and platforms.

eva marine diamond sheet

Made from marine grade UV resistant, closed cell, high density EVA foam material, it stands perfectly even in a strong sunlight area. And the EVA foam material makes it softer and more comfortable for people standing there bare feet than real wood or synthetic flooring. Some would concerned if the boat mat would be not durable to use since it is made from foam material. Well, it may not hard like real wood or PVC flooring, and compete the durability with those two, but with a higher density EVA foam, we are able to compete with other suppliers who try to compromise the density to reach to a lower price.

The sheet comes in 190cm x 70cm, user can cut the sheets into size to fit the shape of boat decking, then just peel and stick since the sheets we offer is with 3M adhesive on the backing. It can be applied on boat decking of course, and other like swim platform pad, helm station pad or simple seat pad.
