Quadruple drum lifting mechanism characteristics
In order to ensure the reliable operation of the lifting mechanism, double brakes are set in the mechanism, each brake can individually brake the full rated load, and its coefficient is 1.25. Due to the inclined design of the wire rope and the possible partial load when lifting billets, the wire ...Read more -
Design of winch rope arranger
In the process of winding the wire rope with the winch drum, especially in the multi-layer winding, we often encounter the problem of poor rope arrangement effect. In view of this situation, our company designed the winch rope arrangement device. The plan is as follows: (1) Rope Angle detection a...Read more -
Instructions for the use of LBS sleeves
(1) The flange of the drum must be kept perpendicular to the wall of the drum under all conditions, even under load (2) In order to avoid the “job-hopping” or “deviant” phenomenon of the wire rope, the wire rope must maintain enough tension, so that the wire rope can alway...Read more -

Service conditions of Lebus groove
1.The flanges of drum shall be perpendicular to drum wall at any conditions,even under the load. 2.The rope must be kept under tension in the process of spooling so that the rope will be crushed against groove wall. When spooling can not meet this condition，a press roller shall be used.It is gen...Read more -
Lebus sleeve is a more efficient approach
Lebus is a very popular rope groove in the lifting industry，LEBUS groove makes the wire rope winding smooth, load evenly distributed between each layer, practice has proved that this technology greatly prolongs the service life of wire rope, data shows that can prolong the life of wire rope more...Read more -
Winch lubrication and its importance
Friction, lubrication theory and lubrication technology are the basic work in winch research. The study of elastic fluid dynamic pressure lubrication theory, the popularization of synthetic lubricating oil and the proper addition of extreme pressure additives in oil can not only improve the beari...Read more -
Features and operating conditions of LEBUS grooves
LBS rope grooves are composed of straight rope grooves and diagonal rope grooves for each round of the drum, and the position of the straight rope grooves and diagonal rope grooves for each round is exactly the same. When the wire rope is wound in multiple layers, the position of the crossing tra...Read more
