Single Jib Portal Crane

Single Jib Portal Crane introduction

Single jib portal crane is the simplicity of mobile harbour cranes, which conforms with Harbor portal crane technical specifications, harbor portal crane safety specification, crane design standards. The single jib portal crane is extensively used for the handling of cargos such as coal, ore on docks and also used to loading and unloading of other cargo ship, etc. The main parameters of the single jib portal crane is shown in the following table:

Components of Single Jib Portal Crane

Single jib portal crane mainly consisted of steel frame, material lifting mechanism, slewing mechanism, crane traveling mechanism, spreader device, i.e. grab, container spreader, magnet, and hook, electrical equipment and safety accessory equipment, etc.

The steel structure of single jib portal crane are made of jib and A-frame, slewing platform and gantry frame, etc.

Single Jib Portal Crane

How It Works

1. Cargo Engagement – The crane’s hoisting device (hook, grab, or spreader) attaches to the load.
2. Lifting – The hoist mechanism raises the load smoothly.
3. Slewing – The jib rotates to position the load over the target location.
4. Traveling – The portal structure moves along rails to extend coverage.
5. Lowering & Release – The load is placed precisely, and the lifting device is released.

This process ensures fast, safe, and efficient cargo handling in demanding marine and industrial environments.
