The Characteristics Of The Grooves
1. It has specifically groove to make wire rope spooling orderly and uniform strength on every layer.
2. It can be calculated the exact forces that the rope imposed on the drum.
3. The spooling is totally under control,which prevents lower layers being crushed or pinched by upper layers
4. With the groove,the continuous groove in the drum is parallel to the flange except for two crossover points on each Revelution where the groove moves across the drum half a pitch to give a pull pitch of movement for each pitch.
Advantages of LEBUS grooves
Double folding rope 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 than 500%, reduce wire rope damage, improve safety, and reduce the mechanical equipment for rope replacement downtime.
Product application:
1. Crane machinery: The bridge lifting machine, Tower crane, Gantry crane,Crawler crane winch
2. The petroleum industry: Oil drilling rig, Petroleum tractor hoist, Petroleum workover rig, Trailermounted pumping unit winch , Logging winch, etc
3. Offshore Marine machinery: Offshore petroleum crane winch, Mooring winch, Traction winch, Man-riding winch, Anchor winch, Hydrologic winch
4. The construction machinery: Building wipe wall winch, Winding hoist, Windlass
5. Mining winch: Dispatching winch, Prop-pulling winch,Sinking winch, etc
6. Engineering machinery: Cable winch, Tower crane, Piling machine, Hydraulic winch
Product advantage:
LBS grooved drum, solved the problem of wire rope spooling.
Compared with ordinary cordless groove (smooth) drum and helical rope groove drum, LBS rope groove has obvious advantages in the multi-layer wire rope spooling, LBS special groove system makes the spooling of wire rope smooth, and the load of each layer evenly distributed, extend the service life of rope, reduce the wire rope damage, improves the safety of the operation of the equipment, and reduces the problem of mechanical equipment shutdown for changing rope.
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 generally recommended that the tension of the rope should be at least 2% breaking tension or 10% working load.
3. The fleet angle range should generally never be more than 1.5 degrees and not less than 0.25 degrees.
4.When the wire rope released from the drum goes around the sheave,the center of sheave should be over the center of drum.
5.The rope must be kept round,not loose,even under the maximum load.
6.The rope must be anti-rotation structure.
7.Pls measure the change of rope diameter under different load.
