Biomass Silo Discharge Systems – Ladder-Type Unloading Scraper – Project Reference.
Industrial equipment manufacturing to customer specifications | Biomass handling systems | Steel and mechanical assemblies
MAXIMUS FAB manufactures ladder-type biomass discharge mechanisms designed for installation at the bottom of silos and biomass storage bunkers. These assemblies form an important part of fuel discharge systems, moving wood chips and other biomass materials towards the discharge point.
Manufacturing is carried out according to technical documentation provided by the customer, taking into account the specified structural, manufacturing and assembly requirements of each project.
These projects demonstrate MAXIMUS FAB’s manufacturing capabilities in specialist steel and mechanical assemblies for the energy sector and biomass handling applications.
Ladder-type scrapers – an essential component of biomass discharge systems
In biomass-fired boiler plants, fuel is commonly stored in silos or purpose-built storage bunkers. Mechanical discharge systems installed at the bottom of these storage units help move the fuel towards the discharge opening.
A ladder-type scraper consists of interconnected structural and moving components that convey the stored material towards the collection point. Depending on the installation layout, the mechanism can operate together with a scraper chain conveyor, which transfers biomass to the downstream fuel-feeding equipment.
A typical process arrangement is:
Biomass silo → ladder-type scraper → scraper chain conveyor → fuel-feeding system → boiler furnace.
The manufacturing quality of the scraper assembly is important for the correct fit and interaction of its components with the other equipment in the installation.

Manufacturing to customer technical documentation
MAXIMUS FAB manufactures ladder-type scraper assemblies based on technical documentation supplied by the customer. This cooperation model allows equipment manufacturers and system integrators to outsource specialist components to an external manufacturing partner.
Depending on the project documentation and agreed scope of supply, manufacturing may include:
- fabrication of the scraper’s steel structure;
- manufacturing of moving components and mechanical assemblies;
- production of connecting, supporting and mounting components;
- preparation of subassemblies for further installation;
- manufacturing inspections within the agreed scope;
- preparation of completed equipment for transport and delivery.
Each project is carried out in accordance with the applicable technical documentation and the agreed manufacturing requirements.
Manufacturing accuracy and component fit
Scraper mechanisms operating at the bottom of biomass silos require careful attention to structural geometry, component alignment, connection quality and conformity with the supplied drawings.
Depending on the design, important manufacturing considerations include:
- compliance with specified dimensions and tolerances;
- correct fabrication of structural components;
- accurate positioning of holes, mounting points and interfaces;
- weld and connection quality;
- preparation of assemblies for installation;
- suitable protection and securing of equipment for transport.
When manufacturing to customer documentation, clear communication between the customer and the manufacturer is essential, together with an agreed definition of quality requirements and inspection scope.

From manufacturing to delivery
Industrial equipment projects involve more than fabrication alone. Completed assemblies must also be prepared for handover and transport.
For ladder-type biomass scrapers, key considerations include production planning, assembly completeness, transport preparation and conformity of the delivered equipment with the agreed project scope.
Photographs documenting manufacturing and delivery provide a practical overview of the project and the equipment produced. They also demonstrate MAXIMUS FAB’s experience in manufacturing components for industrial biomass discharge and fuel-handling systems.
