Crane Hoist Gearbox

The crane hoist gearbox is the core transmission unit for lifting systems. It converts motor speed into torque, ensuring smooth and safe operations. Whether applied as an EOT crane hoist gearbox, an overhead crane hoist gearbox, or a gearbox hoist tower crane, it delivers stable performance under heavy loads. Made from alloy steel with precision ground gears, it resists wear and reduces noise. For demanding jobs, the crane main hoist gearbox and EOT crane main hoist gearbox provide reliable torque support and long service life.

Product Support

Hanko Heavy Industry has decades of experience in manufacturing crane components. Each gantry crane gearbox goes through raw material inspection, heat treatment, and precision machining. Before delivery, sampling inspections by batch are conducted, including ultrasonic testing, magnetic particle inspection, and a load test with no less than 1.1 times the rated load. We are manufacturers of gantry crane gearbox, offering both standard and customized solutions. Our ISO-certified factory, strict quality control, and professional engineering team guarantee safety, durability, and international compliance.

Swivel Crane Hooks

Swivel crane hooks allow loads to rotate freely, reducing wire rope stress and improving accuracy.

Single Crane Hook

The single crane hook is the most common lifting component in hoisting systems. Compared with double hooks, it provides a simple, cost-effective solution for medium loads.

Overhead Crane Hook

The overhead crane hook is a vital lifting component for bridge cranes, gantry cranes, and other overhead lifting equipment.

Mobile Crane Hook

A mobile crane hook is a vital component that connects the crane to the load. Designed for heavy-duty use, it ensures strength, safety, and efficiency.

Forged Crane Hook

A forged crane hook is a key lifting component that ensures both operator and load safety.

Eot Crane Hook

The eot crane hook connects crane and load, ensuring safety and efficiency during lifting. It works with hoist and trolley systems and supports crane main hook and auxiliary hook lifting.
