Fork contact can scratch finished products, tear packaging, deform pallets, or create maintenance work. Protection-sleeve performance depends on material grade, fit, wall thickness, load, movement, contaminants, temperature, and inspection intervals.
当社は製造しています 特注成形ポリウレタン製荷重・フォークブレード保護スリーブ for industrial マテリアルハンドリング equipment. Formulation, hardness, wall thickness, surface, dimensions, and retention can be matched to warehouse logistics, food processing, steel service centers, automotive assembly, and other applications.
Application Examples for Custom Polyurethane Fork Sleeve Selection and Validation
Successful fork protection projects match polyurethane formulation, hardness, geometry, and retention to actual operating conditions. The following application examples show what to review and how to validate a candidate design without assuming a universal result.
Application Example 1 – Warehouse Automation

Daily operating hours
Engineering Review
Review the fork profile, load, product surface, schedule, and retention needs before selecting:
How should polyurethane, rubber, and nylon be compared for fork protection sleeves?
Compare specific grades for abrasion, tear behavior, cushioning, friction, temperature, chemical exposure, marking risk, fit, and cost. No material is universally superior; test representative sleeves with the actual fork, load, product surface, and operating conditions.
How is polyurethane-to-metal bond integrity controlled?
Bond integrity depends on core design, cleaning, surface preparation, bonding system, casting, cure, edge geometry, load, and environment. Define the expected failure mode and inspection or test requirement; no bond should be guaranteed without application data and validation.
How is non-marking performance checked for polished or painted products?
Request a non-marking formulation and test it on the actual aluminum, glass, paint, or other finish under representative load, sliding, temperature, cleaners, oils, and dwell time. Inspect for residue, color transfer, indentation, and scratches before production approval.
How are thickness and hardness selected for heavy-duty fork sleeves?
Use load, fork profile, contact area, available clearance, product sensitivity, impact, sliding, temperature, and wear allowance to select wall thickness and hardness together. Confirm fit, deformation, grip, and product protection with a representative trial.
What compliance or electrical requirements can be specified for polyurethane sleeves?
Food-contact, restricted-substance, antistatic, or electrical requirements depend on the exact formulation, test method, supplier records, destination market, and application. State the required standard and acceptance limits before quotation, then review the applicable declarations or test reports for the selected material.
How are protection sleeves retained on forklift tines?
Retention may use a controlled interference fit, mechanical stop, fastener, or another design approved for the fork and duty. Provide blade width, thickness along the taper, length, tip profile, clearances, load direction, and operating movement, then verify installation and removal on the actual fork.
Can fork sleeves affect forklift capacity, clearance, or load center?
A sleeve adds thickness and may change clearance, load position, visibility, grip, and handling. Confirm the proposed sleeve with the forklift, fork, and attachment manufacturers and the site safety authority; never operate outside the equipment rating or approved handling procedure.
