Wheeled Radial Telescopic Stacker

Also known as a tire-mounted ship loader, the wheeled radial telescopic stacker is a high-efficiency bulk handler for mines, ports, building-materials sites and grain storage. It fuses mobility, radial rotation, boom telescoping and height adjustment into one machine, offering an advanced alternative to fixed stackers. The same unit stacks, transfers and loads vessels.

Key Features and Engineering Highlights

Technical Specifications

Combined stacking and ship loading

The unit conveys material along a telescoping boom that also tilts and rotates radially, so it both builds large land stockpiles and reaches into vessel holds. Hydraulic outriggers stabilise it during the precise discharge phase.

Because no fixed foundation is needed, an operator can shift the machine between berths or from a stockyard to a quay, making one asset cover multiple duties.

Models and reach

RWS1036/RWS1042 (1000 mm belt) and RWS1236/RWS1242 (1200 mm belt) span 36 m and 42 m, discharging at 15.1-17.6 m over a 7-23° working angle. Bulk volume reaches 67,942 m³ at 500 or 700 t/h.

The telescopic-plus-liftable design forms large conical or linear piles and, on the quay, loads barges through to Capesize vessels when paired correctly. It links with a mobile ship loader for crawler-based duties.

Applications and materials

Suited to bulk stacking, transfer and ship loading at mines, ports, docks, building-materials sites, sand yards, grain silos and mixing plants. It handles coal, ores, fertilizer, grain, aggregate, palm kernel shell, wood chip, cement clinker, dry bulk, fly ash, sulphur, asphalt, gypsum, sand and soybeans.

In ports it is a direct answer to the question of how to load vessels without fixed infrastructure; see our guidance on radial telescopic ship loading.

• Port and dock ship loading
• Grain silos and fertilizer stores
• Mine and building-material yards
• Sand, aggregate and clinker transfer

Selection and operation tips

Pick boom length by the largest vessel or pile you must reach; the 42 m unit at 17.6 m discharge covers deep holds and tall cones alike. Use outriggers on every set-up before loading.

Run the telescopic motion to limit free-fall and dust at the hold, and rotate radially to fill multiple holds from one berthing position.

Frequently Asked Questions

What reach and height does it offer?

Boom lengths 36 m and 42 m, discharge heights 15.1-17.6 m, working angle 7-23°.

What is the stockpile or load volume?

Up to 67,942 m³ of bulk at 500 t/h (1000 mm belt) or 700 t/h (1200 mm belt).

Can it load ships without fixed structures?

Yes. Wheeled travel and outriggers let it serve different berths and vessels with no civil foundation.

What materials can it handle?

Coal, ores, fertilizer, grain, aggregate, clinker, fly ash, sulphur, asphalt, gypsum, sand, soybeans and more.
