Motovario, where motion comes to life.
High-Torque, High-Duty Gear Reducers for Bucket Elevators
In bucket elevator applications where continuous, heavy-duty performance is critical, selecting the correct gear reducer is paramount. The Motovario H Series, available from Madacan Africa, is specifically engineered to address high axial and radial load demands, frequent starts/stops, and variable torque conditions commonly encountered in bulk material handling. These helical gear reducers are manufactured with FEM-analysed monobloc housings, ensuring rigid gear alignment and optimal heat dissipation—crucial for prolonged operation in high-temperature industrial zones.
Optimised Gear Geometry for Peak Efficiency
Each unit in the H Series range features carburised and ground helical gears, precision-machined to AGMA and ISO standards. This ensures minimal backlash, reduced friction losses, and superior torque density. Torque ratings span from 150 Nm up to 13,000 Nm, with gear ratios configurable between 5:1 and 600:1, making them suitable for a wide spectrum of slow-speed, high-load elevator systems. Their Class F insulation, IP55 sealing, and thermally stable lubricants make them highly resistant to ingress and ideal for abrasive environments such as mineral processing and cement plants.

Versatile Mounting and Integration Capabilities
The modular design of the H Series allows for foot, flange, or torque arm mounting with horizontal or vertical shaft orientations, supporting diverse elevator head and boot configurations. Their symmetric housing permits dual-direction shaft rotation and facilitates integration into existing elevator layouts with minimal redesign. Shafts are constructed from EN10083/1 42CrMo4 alloy steel and induction hardened to ensure fatigue resistance under cyclic load. This makes the H Series particularly suited to vertically mounted motors driving heavy counterweighted bucket systems.
Extended Service Life and Reduced MTTR
Reliability is further enhanced by double-lip Viton® seals, tapered roller bearings on both input and output shafts, and splash or forced lubrication options that support continuous-duty cycles in Class II Div I hazardous zones. The H Series units are built with maintainability in mind, offering fast Mean Time to Repair (MTTR) through accessible inspection covers and drain/fill plugs. In harsh South African environments, these gear reducers ensure mechanical longevity, operational safety, and reduced total cost of ownership.
