Description
High-Strength · Safety-Certified · All Crane Hook Types · Custom Hook Block Solutions
A crane hook block is the complete lower load-bearing assembly of a hoist mechanism, integrating a forged steel crane hook, pulley sheave system, cross beam, side plates, and bearings into a single structural unit. Our hook blocks are purpose-engineered for Electric Overhead Traveling (EOT) cranes and gantry cranes across a full range of industrial applications.
Manufactured at our own facility in China and exported directly to customers in 60+ countries, our hook blocks cover SWL from 1T to 500T with all major crane hook types available — single hook, double hook, swiveling hook, ramshorn hook, and grab hook. Every unit ships with a crane hook safety latch as standard, undergoes static proof load testing at 2× SWL, and is supplied with full certification documentation.
Whether you are specifying a new crane build, sourcing OEM-compatible replacement blocks, or developing a crane hire fleet, our factory-direct supply chain delivers engineering quality at competitive pricing — without distributor margins.
Advantages
Closed-die forged from 34CrNiMo6 or equivalent high-strength alloy steel. Superior fatigue resistance and toughness versus cast alternatives. Full material traceability (EN 10204 3.1 certs).
Every crane hook includes a spring-loaded forged safety latch. Meets EN 13157, ASME B30.10, and AS 4991 latch device requirements. Non-latched hooks only on documented exemption.
Sheave grooves machined to exact rope diameter tolerance. Reduces rope wear and extends wire rope service life. Groove profiles available for 6×19 and 6×37 rope constructions.
Every assembled hook block is static proof-loaded at twice its Safe Working Load before shipment. Load test certificate issued with each unit as standard.
Designed to FEM 1.001 and DIN 15401/15402. Duty classes M1 through M8 specifiable at order stage. ASME B30.2 configurations available for US/Canadian projects.
We manufacture and sell direct. No distributor, no agent markup. Typical saving versus channel pricing: 15%–35%. Volume pricing tiers available for crane OEMs and EPC contractors.
Dimensionally compatible replacements for Demag, Konecranes, ABUS, SWF, Street Crane, and other major OEM brands. Provide part number or dimensions for compatibility confirmation.
Wooden case export packing with anti-rust treatment. FOB, CIF, DDP terms. Experience with LC, T/T, and open account. Shipping documents in English, Spanish, or Arabic on request.
