Scraper Floor Drives from Hydromot – Frequently Asked Questions

What is a scraper floor drive and what is it used for?

A scraper floor drive, also called a hydraulic reduction gearbox, is specifically designed for the powerful movement of scraper floors. It is mainly used in modern agriculture and industry, e.g. in:

  • Forage wagons and silage trailers
  • Slurry tankers
  • Conveyor belts and silage conveyors

What are the advantages of Hydromot scraper floor gearboxes?

  • High performance and torque transmission even at low input speed
  • Robust cast iron design for long service life
  • Flexible installation options for different machines
  • Low maintenance due to wear-resistant materials

Are Hydromot scraper floor gearboxes compatible with products from other manufacturers?

Yes. Our gearboxes are designed to be interchangeable with those from common manufacturers such as Berma or Rögelberg. This gives customers maximum flexibility in spare parts and maintenance.

What materials are scraper floor drives typically made of and why?

  • Housing: Cast iron for maximum stability and load capacity
  • Gears: Precision-engineered steel for wear resistance
  • Seals & Bearings: Special seals and needle bearings for long service life
  • Hydraulic motors: Alloy steel with precision flange mounting

What are the technical specifications of scraper floor gearboxes?

  • Gear ratios: 1:3 up to over 1:40 (e.g. 1:35.7 or 1:8.15)
  • Torque: Up to 10,000 Nm (depending on model 900–5000 Nm)
  • Input: Hydraulic motor with 25 mm shaft and SAE A flange

Maintenance:

  • Regular oil changes (SAE 80W-90 / SAE 90 EP)
  • Check for leaks
  • Inspection of bearings and seals

How to select the right scraper floor gearbox?

Important selection criteria are:

  • Required torque and gear ratio
  • Hydraulic motor size and displacement
  • System pressure and oil quality
  • Matching output shafts and flange types
  • Safety reserves for loads and temperature
