Smart Excavators: Lift Yourself to Fix a Chain!- Good tools and machinery in daily work

Witness the unique ability of an excavator to lift part of its own body using its hydraulic arm. This technique is particularly useful for performing maintenance, repair or removal of heavy and bulky chains (tracks) without the need for external lifting equipment.

The function is to use the hydraulic system of the arms (boom and arm) and attachments (bucket, etc.) as levers to lift a portion of the machine's undercarriage (lower frame with tracks) off the ground, allowing access for maintenance or repairs.

This self-lifting capability is a very practical design feature on track excavators. It demonstrates the machine's independence in performing maintenance in the field, saving time and money compared to calling in other machines to lift it.

The excavator operator can place the bucket or end of the arm in the proper position on the ground or a firm pad, and then carefully extend the hydraulic cylinder of the arm to push down and lift the side of the machine. The use of additional beams or jack stands under the raised frame is highly recommended for safety during the work.
