Bulk Material Handling Engineering

Conveyor Systems

Lassing Dibben has completed many bulk material handling systems involving stockpiling, material transfer, shipping, and receiving for mining, pulp and paper, aggregate, cement, and other industries. Yard conveyors and in-plant systems have been developed using our extensive experience and standards.

Projects, including Pipe Conveyors, Loop Belts, Belt Feeders, Flexible Wall Conveyors, and other special design material handling equipment are part of our experience. It is an ongoing mandate within Lassing Dibben to maintain a leadership role in the bulk material handling field and this requires complete knowledge and experience in all means of material handling.


Lassing Dibben has designed radial, fixed pivot, mobile luffing and slewing stackers for the mining, aggregate and cement industries internationally. The company is also called upon to periodically inspect these units. Existing designs can provide cost and time saving solutions in many new applications.


Radial, luffing, slewing, fixed and mobile stacking conveyors for ship loading of wood products, ores, aggregates, etc. have been designed by Lassing Dibben. Our experience also includes projects involving grab cranes and receiving systems from self unloading ships and barges as well as lightering operations. These systems have included deck mounted and dock mounted conveyors up to 102″ belt widths.

Marine Applications

Lassing Dibben has worked for some of the leading ship owners and builders around the world and has designed award winning (Schreyer Award 1989) articulating boom deck mounted ship unloading gear. Several innovative designs have developed from our work. Lassing Dibben has also design loop belt systems for self unloading vessels.


Lassing Dibben is often called upon to come up with a number of concepts at the initial stage of a project and the related estimated costs for each. After the selection of the preferred concept, a more thorough cost estimate can be performed. Often this leads to the preparation of design drawings and specifications which are used for the construction phase of the project. Many of our completed projects originally started out as feasibility studies.
