5t Hydraulic Winch Wireline & Accessories for ZJ40 Truck-mounted Drilling Rig

1

Wireline of 5t hydraulic winch (Z02200000002AA)

High-carbon steel wire (65Mn) with galvanized surface; multi-strand twisted structure; tensile strength ≥1860MPa, compliant with API-9A.

1. Fatigue breakage from repeated bending during winching; 2. Abrasion from contact with winch drum and pulleys; 3. Corrosion from on-site humidity and drilling fluid mist.

1. Rotate wireline regularly to distribute wear evenly; 2. Clean and lubricate with wire rope grease weekly per API-9A guidelines; 3. Avoid overloading (max 5t, per winch rating).

2

Wireline (P9990029AA)

High-strength galvanized steel wire; compact twisted structure; anti-rust coating; wear-resistant core for load-bearing stability.

1. Surface wear from friction with rough surfaces; 2. Strand breakage from sudden load surges; 3. Coating peeling from chemical exposure (drilling fluids).

1. Inspect for broken strands weekly (replace if ≥3 strands in one lay); 2. Avoid sudden starts/stops during winching; 3. Use chemical-resistant lubricant to protect the coating.

Wireline (4400200014)

Stainless steel (304) reinforced steel wire; corrosion-resistant; flexible structure for adaptability to winch drum rotation.

1. Fatigue from cyclic load cycles; 2. Bending damage from excessive drum tension; 3. Pitting corrosion from saltwater (for onshore/offshore hybrid operations).

1. Maintain proper drum tension to avoid over-bending; 2. Conduct non-destructive testing (NDT) monthly; 3. Rinse with fresh water after saltwater exposure and reapply grease.

Line clamp 14KTH (4400200116)

Malleable cast iron (KTH350-10); heat-treated for toughness; zinc-plated surface for anti-corrosion; precision-threaded fasteners.

1. Thread wear from repeated tightening/loosening; 2. Deformation from excessive clamping force; 3. Corrosion from on-site moisture and debris.

1. Tighten to specified torque (per API-8A) to avoid over-clamping; 2. Replace if thread wear or deformation is detected; 3. Clean and reapply anti-corrosion spray quarterly.

2

Lantern ring WT14 (4400200246)

Carbon steel (Q235A) with powder coating; wear-resistant inner surface; high-temperature resistant material for hydraulic winch working conditions.

1. Abrasion from wireline sliding during winching; 2. Coating peeling from impact with debris; 3. Deformation from misalignment with wireline.

1. Align with wireline to reduce sliding friction; 2. Inspect inner surface weekly for wear; 3. Install a protective sleeve to prevent debris impact.

3

Shackle S-BX6.5-7/8 (4103200049)

Alloy steel (20Mn2) with forging treatment; quenched-tempered for high strength; galvanized surface; precision-machined pin.

1. Pin wear from rotational movement; 2. Fatigue cracks from heavy load cycles; 3. Corrosion from drilling fluid and humidity.

1. Inspect pin tightness before each use; 2. Conduct NDT semi-annually to detect hidden cracks; 3. Never use worn shackles (replace if pin play exceeds 0.3mm).

4

Single leg chain sling (5m chain）

Alloy steel (35CrMoA) chain links; heat-treated for wear resistance; galvanized surface; load-bearing capacity matched to 5t winch.

1. Link wear from friction with lifted equipment; 2. Fatigue damage from repeated load bearing; 3. Corrosion from on-site moisture and chemical contaminants.

1. Inspect chain links for wear weekly (replace if link diameter reduces by ≥10%); 2. Avoid dragging the sling on rough surfaces; 3. Store in a dry, dust-free area when not in use.

Are these wirelines interchangeable with other 5t winch models?

No. These wirelines (Z02200000002AA, P9990029AA, 4400200014) are custom-matched to the 5t hydraulic winch of ZJ40 truck-mounted drilling rig. Interchange with other models may cause load mismatch and safety hazards, violating API-9A standards.

How often should the single leg chain sling be inspected?

Inspect weekly for link wear, cracks, or corrosion; conduct NDT semi-annually. Replace immediately if any damage is found, per GB/T 2585-2008 chain sling safety standards, to avoid load failure.

What lubricant is suitable for the winch wirelines?

Use API-9A compliant wire rope grease (ISO VG 150), which offers wear resistance and corrosion protection. For humid or chemical-exposed environments, choose water-resistant and chemical-resistant grease to extend service life.
