1. Ship Unloaders

Ship Unloaders

TAKRAF is able to assist across a wide-range of ship and unloading machines catering to various material types, required tonnages and even vessel sizes and types.

Grab-type ship unloaders are particularly well-suited to both sea and inland import ports that discharge a number of different material types as the grab system can work across various materials. These unloaders have proven themselves over decades of operation and are extremely reliable.

Our machines are all specifically designed to our client's requirements and incorporate various solutions according to their specific application.

Grab-type ship unloaders are able to handle all bulk material across the entire range of different particle sizes and/or material properties; including, amongst others, coal, iron ore, bauxite, limestone, phosphate, petroleum coke, various fertilizers, potash and sulphur. In fact, these machines, if fitted with hooks or spreaders, can even assist with the unloading of general cargo or containers.

Discharge of material from the vessel is intermittent and is usually into a machine-mounted discharge hopper, although this can be specified differently according to requirements. Once in the hopper, the process is then continuous as a belt conveyor then transports material to the relevant storage area.

Grab-type ship unloaders are offered in the following versions:

Grab ship unloader with cable operated grab trolley (GSU)

These machines are designed with a seaborne arm that can be raised and lowered together with a cable-operated grab trolley. The drive winches that manage all working movements, ie. grab lifting, grab lowering, grab opening and closing, cross travel, boom lifting and lowering are all mounted in the main structure. Due to the relatively small mass of the grab, high trolley speeds and accelerations can be achieved.

Basic technical data:

  • Load capacity: 12,5 t to 60 t
  • Unloading capacity: 400 t/h to 2,600 t/h
  • Rail gauge: 7 m to 28 m
  • Vessel size: 10,000 DWT to 350,000 DWT

Grab ship unloader with trolley mounted winches (GVB)

These machines are designed in such a manner in which the motors for the grab actions and cross travel are housed in the trolley, whilst the driving winches for lifting and lowering the boom are mounted in the main structure.

Basic technical data:

  • Load capacity: 30 t to 85 t
  • Unloading capacity: 400 t/h to 4,500 t/h
  • Rail gauge: 30 m to 90 m
  • Vessel size: 10,000 DWT to 350,000 DWT

Continuous Ship Unloaders

These machines are particularly well-suited to import ports that discharge bulk material, especially those that discharge high volumes of material.

A bucket-chain elevator is employed to effectively claim all material from the ship's hold and transfer to a conveying system. Since unloading is continuous, these machines are highly efficient and are able to discharge significant volumes in a short space of time.

Due to the enclosed nature of these machines, they significantly reduce the environmental footprint, specifically dust emissions, and are well-suited to operating in particularly sensitive areas.
