Lbs Grooved Wire Rope Quad Beam Crane Drum Non Standard Custom

LBS Grooved Wire Rope Quad Drum For Beam Crane Non-Standard Custom

There are two kinds of hanging beam cranes: one is a double deck trolley composed of the upper rotating trolley and the lower walking trolley; The upper trolley is composed of trolley rotating mechanism, double drum, double lifting mechanism and spreader. The second is a single trolley, double drum, double lifting point lifting mechanism, rotary spigot and other components. The lifting mechanism realizes the rising and falling of the billet, and the upper rotating trolley or rotary spanner realizes the 90° rotating stacking of the billet. In the production practice, it is found that these two kinds of cranes have complex structure, and the sling will have large deflection and sway in the process of high speed operation, and the work efficiency is low and the performance is poor. A quadruple reel design solves this problem.

In the design of lifting mechanism, the selection of pulley group ratio not only has great influence on the selection of diameter of wire rope, pulley and drum, as well as the calculation of static torque of low speed shaft of reducer, but also directly affects the effective working number of wire rope on drum, and then affects the distance between steering pulley and drum. The closer the distance is, the greater the deflection Angle of the wire rope in and out of the pulley and reel, and vice versa.
The wire rope winding system has 4 ropes, and one end of the rope head is fixed on the quadruple reel by wire rope pressing plate. The four ropes are arranged symmetrically in both directions. The two longitudinal ropes are symmetrically wound into the rope groove inside the drum, wound out from the opposite direction of the drum, and pass through the respective steering pulley and spreader pulley in turn. The other end is connected with the rope head fixing device to form two longitudinal symmetrical lifting points. The two transverse ropes are symmetrically wound into the rope groove outside the drum, wound out in the same direction from the drum and pass through the respective spanner pulley, and the other end is connected with the rope head fixing device to form two transverse symmetrical lifting points. The four lifting points were positively cross distributed.

First, the wire rope is not sorted out before hoisting, and the wire rope is checked by itself, and the wire rope with a higher proportion of broken rope should be replaced in time. Second, do a good job of fixing the winch, the base of the winch is unstable, and the winch is prone to displacement when lifting. Show ropes. Third, when lifting, adhere to the wire rope and drum into a 90 degree Angle. The above is to avoid the method of small winch wire rope chaos. There are many parts on the winch. The effect of different parts is different, and the fault response method will be different

the use of environment:

1. Outdoor use is allowed;

2. The altitude does not exceed 2000M;

3. Ambient temperature -30℃ ~ +65℃;

4. It is allowed to work under rain, splash and dust conditions.

This LBS reel model is: LBSZ1080-1300

Represents the diameter of the Ribas drum is 1080mm, the length is 1300mm,

Provide wire rope laying service, in the site with the ship winch wire rope chain connection or drilling rig, crane link cable laying operation, to better protect the wire rope.

Winch drum is an important part of oil rig winch, winch drum

One end of the wound wire rope is fixed at the drum rope socket through a rope clip, and the other end

The guide wheel of the sky car is introduced into the trolley pulley group, and the trolley pulley group is installed

Equipped with hooks, faucets and drill pipe strings. When the winch works, it is wound

The steel wire rope on the drum realizes the action of winding and releasing the rope through positive and negative rotation of the drum

The drum bears the fast rope tension of the wire rope, and the drum structure must meet the strength

Outside, but also to ensure that the wire rope winding neatly.

With the development of oil drilling winches in recent decades, winches appear more

The transmission form and the structure form, but the winding rope rule of the winch drum is not change, our company developed LEBUS rope groove has obvious advantages. LEBUS rope groove double line form, suitable for multi-layer winding, can effectively reduce or avoid steel wire Rope disorder phenomenon. In the design process of the drawworks drum, the drawworks drum has a large opening range Small, bottom diameter selection, position of guide block, rope socket structure, rope groove spacing, rope groove the spiral Angle of the parallel section and the climbing section will affect the effect of drum rope winding, becauset this, the study of winch drum structure and characteristics, will help to reduce or avoid oil field field hoist drum disorderly rope phenomenon, prolong the use of wire rope and drum life.

When the split type drum fence skin is installed, the split fence skin sleeve is wrapped on the smooth slotless drum, and is closely connected with the drum through bolts or welding, so that the original smooth surface of the drum outside the surface becomes the form of lebus double folding rope groove, which is convenient for the application of winch modification or replacement of the drum.

Early introduction the advanced technics form domestic and foreign,after years R&D,our company had a major breakthrough in lifting machinery's multilayers spooling field and obtaied the production patent of LBS groove in 2010.Meanwhile we created our brand -LBS. At the prosent, the company have formed a stable and serialized production mode.
