Traction winch system sheaves absorb high line pull loads by allowing the cable to work in a formed groove at the required minimum bend diameter.

. According to Ashby et al. Department of the Navy was reorganized as. It depends on lifting height frequency of use and even the rope diameter as to the type of wire rope most suitable for.

When the wire rope need to wind many layers the LBS groove can fix the crossover point of the upper rope and the lower rope through crossed groove which could control the crossover point and make it finished in the crossed groove. Rope drums with grooves cut directly into themWinch drum with flange the LBS groove is cut directly into the body of the drum according to customers requirements the flanges are either welded or screw-bolted. WINCH DRUMS FOLLOWING LIGHTWEIGHT DESIGN PRINCIPLES P.

Many crane models have a two sided grooved drum one part of it is left the other right lay grooved. This applies to smooth as well as to grooved drums. Pitch circle diameter is 27m and the Totals FPSO winches length between flanges is 17m.

Known for the design of the winch drum the shell of which is made with a spiral groove and a smooth part the fastening of the ends of the ropes to which fasteners installed in performed on the smooth part of the screw holes AS. Each vessel has two 400t capacity winches.

This single-layer effect is significant when compared with high line pull conditions in a conventional drum winch in which cable works on itself as a result of multiple layer wraps. Empty winch weights range from 300 lb.

3 the selection of materials in engineering design involves. As an example a grooved drum made for 14-inch rope may have a pitch of 250 inches. The GWG Grooved drum winch ensures very specific rope spooling higher capacity models are equipped with two speed gearing for ease in handling heavy loads.

1 over the actual wire rope diameter. However heavy tensile loads will result in severe pinching of the wire rope and galling of the drum groove especially with a lubricant-starved 304 stainless wire rope. If a rope of this size were to be operated on a drum with a 250 inch pitch crowding would occur and the rope would be forced out of the groove.

Lebus also adjusted the level winders which is a mechani-cal rope guide system and changed the gear ratio to match the number of pitches on the Lebus groove. The drum V-groove design which is not consistent with the recommendations of the Wire Rope Users Manual maybe acceptable for light loads. These are being produced in Le Creusot France by NFM Technologies.

Drum core Flanges Shaft Etc. Applications with deflection angles of more than 15 use 60 opening. The side-by-side two drum unit aboard the icebreaker Nathaniel Palmer The term Single Drum Winch can be a misnomer since two or three Load Drums can be combined on a single structure in side-by.

The valving to your winch design should work such that air or oil to your air or hydraulic motor should be provided BEFORE air or oil reaches and releases the band or disc brakes otherwise when hoisting or pulling up a slope you can have an overrunning load in which - should your brakes be released BEFORE your motor inlet ports are FULLY pressurized -. For normal applications use 35 to 45 opening. Winch loads are light and infrequent.

Opening angles below 35 must be avoided. It is composed of two parallel grooves and two crossed grooves in each circle of the winch drum. Lebus Grooved Winch Drum With Sleeves.
