Hoist unit general overhaul

A cost-effective alternative to hoist replacement

Machinery components experience fatigue and wear-and-tear whenever a crane is working. As time passes, the theoretical service life of a hoist unit decreases, and the wear on components could result in certain hazards.

Regulations require that power-driven rope and chain hoists, as well as crane hoist units, be taken out of operation when the theoretical duration of service has elapsed, unless a general overhaul is carried out to allow further use of the equipment.

A general overhaul should be performed on hoists when the remaining Safe Working Period (SWP) is less than 10%. If you are not able to determine the remaining SWP for your hoist unit then a special assessment should be carried out after 10 years of service life to determine if the hoist is a candidate for an overhaul.

Benefits of a General Overhaul

  • Satisfies regulatory requirements helping you stay compliant
  • Helps maintain equipment performance and availability
  • Helps increase safety and reduce downtime by replacing parts before they wear out and thereby contribute to equipment failures
  • Can help reduce unplanned downtime
  • Genuine spare parts can help provide the same quality level as a new hoist
  • Can be coordinated around your production schedule

For Konecranes and Demag wire rope hoists and chain hoists

A Konecranes General Overhaul (GO) includes a complete package of genuine parts that must be replaced during a GO. A Konecranes Service technician will also check the other components of the hoist and suggest repair or replacement as needed.

The hoist will be fully tested according to regulations and the GO is documented in the hoist test and inspection booklet. After an overhaul is performed, the way that your hoist unit works, its performance values and expected service life are comparable with a new one.

The general overhaul can be performed either in the Konecranes Repair Centre or on-site at your facility.
