Products classified under HTS 8431.31.00.20
Skip Hoist Cable Sheave Pulley
Cast iron pulley with grooved sheave for guiding hoist ropes in skip hoist mechanisms, ensuring smooth vertical movement of material skips. Tailored for high-load mining applications, it qualifies under HTS 8431.31.0020 as a principal part of skip hoists.
Skip Hoist Skip Bucket Hinge Pin
High-tensile alloy steel pin for hinging the dump mechanism on skip hoist buckets, enabling controlled unloading of materials. Precision-machined for skip hoist pivot points, HTS 8431.31.0020.
Skip Hoist Overwind Protection Sensor Mount
Machined mount for limit switches detecting skip overtravel in hoist systems, preventing accidents. Dedicated to skip hoist safety, HTS 8431.31.0020.
Skip Hoist Deflector Plate
Wear-resistant deflector plate directing material into skip bucket during loading. Specific for skip hoists, HTS 8431.31.0020.
Skip Hoist Tension Weight Roller
Roller assembly maintaining constant rope tension via counterweight in skip hoists. HTS 8431.31.0020 part.
Skip Hoist Shaft Guide Shoe
Sliding guide shoes reducing lateral movement of skips in hoist shafts. Mining-specific, HTS 8431.31.0020.
Skip Hoist Control Pendant Station
Rugged pendant control box with buttons/joystick for skip hoist operators. Mechanical enclosure for 8428 parts, HTS 8431.31.0020.
Skip Hoist Bucket Assembly
A heavy-duty steel bucket designed specifically for skip hoists used in mining and construction to transport bulk materials vertically. It features reinforced edges and attachment points for cables or chains, classified under HTS 8431.31.0020 as a part solely for skip hoists within heading 8428 machinery.
Skip Hoist Guide Rail Section
Precision-machined steel rail segments that guide the skip bucket along its vertical path in skip hoist systems for industrial lifting. Essential for alignment and stability in mining operations, this part is classified under HTS 8431.31.0020 due to its principal use with skip hoists of heading 8428.
Skip Hoist Safety Brake Lining
High-friction composite brake linings custom-fit for skip hoist emergency stop mechanisms, preventing uncontrolled descent in vertical material transport. Designed solely for skip hoist braking systems in heading 8428, per HTS 8431.31.0020.
Skip Hoist Counterweight Frame
Structural steel frame assembly holding concrete counterweights in skip hoist systems for balancing heavy material loads during ascent/descent. Principally used with skip hoists of 8428, thus HTS 8431.31.0020.
Skip Hoist Rope Anchor Clamp
Forged steel clamp for securing hoist ropes at the skip bucket or headframe in skip hoist installations, rated for extreme tensile loads. Exclusive to skip hoist rope terminations under heading 8428 parts, HTS 8431.31.0020.
Skip Hoist Loading Chute Liner
Abrasion-resistant liner plates made of manganese steel for the loading chute of skip hoists, protecting against wear from falling ore. Tailored for skip hoist material entry points in mining, classified HTS 8431.31.0020.
Skip Hoist Door Interlock Mechanism
Electromechanical interlock assembly preventing skip hoist shaft door opening unless skip is positioned correctly, enhancing safety. Integral safety part for skip hoists of 8428, per HTS 8531.31.0020—no, 8431.31.0020.
Skip Hoist Head Sheave Bearing Housing
Heavy cast steel housing for self-aligning bearings in the head sheave of skip hoists, supporting rope guidance at the top structure. Specific to skip hoist top assemblies in heading 8428, HTS 8431.31.0020.
