Large Tonnage Stable Rope Arrangement Cranes Used Hydraulic Winch: Specifications, Ordering and Support Questions

The following questions and answers are drawn from documented product information for the Large Tonnage Stable Rope Arrangement Cranes Used Hydraulic Winch (LBS series Grooved Winch Drum) supplied by Shijiazhuang Junzhong Machinery Manufactruing Co., Ltd. Each answer is limited to what is supported by confirmed product materials; specific pricing, delivery lead times, and project-specific parameters should be confirmed directly with the supplier.

What is the Large Tonnage Stable Rope Arrangement Cranes Used Hydraulic Winch, and what is it designed for?

The LBS series slot-type (Lebus groove) winch drum is an engineering winch built for stable, multi-layer rope winding under large-tonnage conditions. Its primary functions are retrieving and releasing ropes and lifting heavy objects. Documented applications include marine and offshore platform cranes, oil workover and drilling winches, logging rope winding equipment, wall-wiping machine winches, and helicopter motor winches, as well as general civil construction, mining, water conservancy engineering, forestry, docks, and factory installation projects.

What are the key technical specifications?

The product is catalogued under type specification LBSSPW-202309006 and carries the LBS brand. Key parameters from the confirmed product sheet:

Specific configurations beyond these ranges can be discussed with the manufacturer.

What certifications does the winch hold?

The product has the following certifications: ISO 9001, CCS (China Classification Society), and ABS (American Bureau of Shipping).

What is the rope groove type, and why does it matter for crane applications?

The drum uses a Lebus groove design (referred to as LBS slot type in product documentation). The Lebus groove pattern guides the rope into a stable, repeatable layer-by-layer arrangement during winding and unwinding. This is particularly important in large-tonnage crane and lifting applications where uncontrolled rope stacking can cause uneven drum loading, accelerated rope wear, and unsafe spooling behaviour.

Can the winch be customized to match a specific crane or project requirement?

Yes. The product sheet explicitly states that specific specifications can be customized according to requirements. Parameters open to discussion include rope capacity, rope diameter, winding direction (left-hand or right-hand), color, and overall configuration. The supplier operates a CNC Center production facility and has documented experience adapting the LBS series for varied industrial environments. Buyers should contact Shijiazhuang Junzhong Machinery Manufactruing Co., Ltd. directly to discuss project-specific needs.

What are the minimum order quantity and supply capacity?

The product listing records a minimum order quantity (MOQ) of 1 piece for the winch unit. The published supply ability for the broader LBS product range is listed as up to 10,000 pieces per month. FOB pricing is indicated in the range of US $0.5–$9,999 per piece depending on configuration; exact pricing for large-tonnage or customized units should be confirmed by quotation.
