Road-mobile unloaders: your terminal on a trailer

Siwertell road-mobile unloaders provide the ideal solution for customers using jetties with minimal infrastructure, especially when they have operations at more than one location.

They can handle a wide range of dry bulk materials at capacities of up to 500t/h and have a totally-enclosed conveying line, offering flexible, environmentally-friendly, economical operation.

Road-mobile units are based on screw conveyor technology. The folding structure is mounted on a semi-trailer for rapid self-propelled transportation between ports. It takes only 30-45 minutes to complete the unfolding operation. Packing away is equally rapid and these tasks can be carried out by a single operative.

Alternative installations available

Some customers need small unloaders, but without the full road-mobile capability. The unloader can be installed on a fixed gantry or on a foundation turret. These configurations require the ship to be moved along the jetty during unloading operations. If a degree of in-port mobility is required, a gantry-mounted unloader can be equipped with self-propelled rubber wheels or steel wheels for installation on rails.

Economical and environment friendly

Siwertell’s screw-conveying system provides continuous, high-capacity through-ship performance, cutting unloading times and shipping costs. Energy costs are very low per metric ton handled. An enclosed system eliminates spillage; therefore there is no loss of material or clean-up costs. Maintenance and spare parts expenses are kept to a minimum as Siwertell road-mobile unloaders are largely based on readily-available standard components. Staffing costs are low as only one person is required to operate a Siwertell road-mobile unloader.

A model to suit all operations

Siwertell road-mobile unloaders are available in three different sizes – the Siwertell 5 000 S, 10 000 S and 15 000 S – the largest offering an unloading capacity of up to 500t/h for discharging ships up to 15,000 dwt.
