Construction machines such as excavators, cranes and compaction equipment are operated under extreme conditions on construction sites: dust, mud, impact loads, extreme temperatures and long operating hours without servicing opportunities characterise their use. In this environment, drive components must be extremely robust and reliable. A breakdown on the construction site causes not only repair costs but also delays in the building project.
For rotating installations, slewing gears and lifting systems on construction machines, drive elements with high load capacity and robust construction are required that work reliably even under permanent impact and vibration loads.
WMH Herion supplies slewing bearings, bevel gear units and robust drive elements for construction machinery applications. The heavy-duty slewing bearings with integrated toothing are particularly suitable for slewing gears and rotating installations on excavators and cranes.
For chain drives and undercarriages on construction machines, WMH Herion supplies sprockets in robust versions with hardened teeth. The stock programme ensures that spare parts and replacement components for common types of construction machine can be procured quickly.
For construction machines, WMH Herion offers slewing bearings in heavy-duty design for slewing gears, robust bevel gear units for angular drives as well as sprockets with hardened teeth for undercarriages and chain drives. All products are designed for continuous use under mechanical impact loads.
WMH Herion supplies drive assemblies for slewing gears, lifting systems and chain drives on construction machines that are designed for shock-loaded outdoor operation. The systems are designed for the specific load and operating requirements of the construction machine.
What distinguishes WMH Herion as a partner?
Construction machines and earthmoving equipment require drive components with high load capacity, impact resistance and resistance to dust and moisture. WMH Herion manufactures spur gears, racks and couplings that permanently withstand these conditions, in proven standard versions and as custom production to your drawings. Our stock programme with over 12,000 items ensures short delivery times even when the need arises at short notice.
Our engineering and production department is networked directly with technical sales. This means for you: technical questions are answered without detours, special requests are assessed quickly and supply chains are kept stable. From the design to the delivery: ISO 9001 certified, with 100% inspection of safety-critical components.
Which slewing bearings are suitable for excavator slewing gears?
For excavator slewing gears, slewing bearings with a large diameter and high axial and moment load capacity in a geared version are suitable. WMH Herion supplies slewing bearings with external or internal toothing in various diameters that can be used directly as a drive ring for the slewing drive.
Are sprockets for excavator undercarriages available in robust versions?
Yes. WMH Herion supplies sprockets in robust versions with induction-hardened teeth for undercarriage applications on construction machines. Various pitches and tooth widths are available, on request also in special dimensions.
Does WMH Herion also supply complete assemblies?
Yes. In addition to individual components, we offer assembled handling axes and complex multi-axis systems, fully assembled, tested and ready for use.
How quickly are standard items available?
Most items from the stock programme are available immediately and are delivered within a few working days. For custom-made solutions, we discuss the delivery time individually.
