5-7 Ton Forklift Brake Drum — Heavy-Duty Cast Iron

This heavy-duty brake drum is specifically engineered for 5-7 ton capacity counterbalance forklifts, providing the massive friction surface area and thermal mass required to safely decelerate heavy loads in demanding industrial environments such as ports, steel mills, lumber yards, and heavy manufacturing facilities. Cast from high-grade G3000 gray iron with a carefully controlled carbon equivalent and graphite flake morphology, this drum offers superior heat absorption during repeated heavy braking events and rapid heat dissipation through its oversized cooling rib design. The braking surface is precision-machined to a smooth finish (Ra 1.6μm or better) that provides immediate, full-contact brake shoe engagement from the first stop — eliminating the extended bedding-in period that can compromise safety during the critical post-installation phase.

The drum features an extra-thick wall section (30% greater than 3T-class drums) that provides extended wear life and maintains structural integrity at elevated operating temperatures. The center pilot bore is CNC-machined for zero-play fit on the wheel hub, ensuring concentric rotation and eliminating the pedal pulsation and uneven shoe wear that result from hub runout. The wheel stud pattern is precisely drilled with chamfered lug seats for proper fastener seating torque. Deep circumferential and radial cooling ribs are cast into the outer drum surface, significantly increasing the convective heat transfer area and reducing peak brake temperatures during long downgrade descents or frequent stop-and-go operation in high-throughput logistics centers.

Compatible with 5-7 ton forklift models from HELI (CPCD50-CPCD70), Hangcha, Lonking, Tailift, and other domestic and Asian-market manufacturers using drum-type front brake systems. Always replace brake drums in matched axle pairs (both left and right simultaneously) to maintain balanced braking performance. Before installation, verify the drum inside diameter with a micrometer — do not install if the new drum ID differs from the specification marked on the original drum by more than 1mm. Inspect and repack wheel bearings during drum replacement, and replace the hub oil seal if any signs of leakage are present.

Compatible Forklift Models

Each brake drum is subjected to multi-point dimensional inspection, dynamic balance verification, and surface finish quality check before packaging. The machined friction surface is coated with a water-displacing rust preventative that must be cleaned off with brake cleaner before installation. The drum is packed in a reinforced heavy-duty carton with foam padding. 12-month warranty. Installation critical check: after mounting and torquing lug nuts, measure drum runout with a dial indicator at the friction surface — maximum allowable 0.15mm TIR.
