Automatic Lubricating System for Demolition Excavators


  • Large reservoir for very long operating times without refilling
  • Particularly economical operation: Grease from large containers
  • Optional lubricant level monitoring for highest security
  • Tried-and-tested technology with desmodromic pump elements
  • Also with hydraulic drive


  • BEKA HAMAX EP consists of a grease pump with reservoir (capacity 2 – 16 kg) up to 3 pump elements PE-120 or PE-170 (fixed or variable).
  • To protect the pump against vibrations, it is installed directly at the excavator.
  • The lube point at the tool is connected to the pump by a high-pressure coupling and a high pressure hose.
  • As soon as the hammer is activated, the pump supplies the lube point with chisel paste.
  • The output is regulated by an adjustable pump element.

BEKA HAMAX Special Feature
Desmodromic activation of the pump elements for highest operational reliability in a wide temperature range from -35 up to +80° C.

Electronic Control
The electronic control unit in the SEP-8 monitors the lubricant level in the reservoir. If the level is too low, the pump is switched off and a fault message is generated.

A start release relay can be integrated optionally: With start release relay it is not possible to start the machine if the reservoir is empty.

A very important feature especially for rental machines.
