Forks: Capacity 1000-5000 kg, Width 100-200 mm

Component Specifications

Definition

Forks are the primary load-bearing components of forklift trucks, consisting of two parallel horizontal arms that slide under pallets or loads to lift, transport, and stack materials. They are engineered to withstand substantial vertical and horizontal forces while maintaining precise dimensional stability for safe material handling operations.

Working Principle

Forks operate on the lever principle, where hydraulic cylinders apply force to lift the carriage assembly, transferring the load's weight through the forks' structure to the forklift's mast. The tapered design allows easy insertion under loads while the reinforced heel provides maximum strength at the lifting point.

Materials

High-strength alloy steel (typically ASTM A572 Grade 50 or equivalent), heat-treated to 40-45 HRC hardness, with yield strength of 345 MPa minimum and tensile strength of 450-550 MPa.

Frequently Asked Questions

What are the main types of forklift forks?

Standard forks (non-tapered), tapered forks (for easier pallet entry), block forks (for specific applications), and adjustable forks (with variable spread).

How often should forklift forks be inspected?

Daily visual inspection for cracks and deformation, with formal dimensional inspection every 6-12 months depending on usage intensity.

What causes fork failure?

Overloading, impact damage, fatigue from cyclic loading, improper handling, and material defects.
