Load arrester: holding a load before it falls

A load arrester works like a self-retracting lifeline, but for equipment: its cable follows the load during handling and locks instantly if the load falls. It secures, for example, a part lifted by a hoist, equipment suspended during maintenance or a load handled above an occupied area. KRATOS SAFETY offers the SENTINELS range, from 250 kg to 1000 kg.

Choosing a load arrester

  • By weight: the maximum allowable load (250, 300, 400, 500 or 1000 kg) must cover the mass of the load and its lifting accessories.
  • By height: a cable length of 10 to 20 m, chosen to cover the full travel of the load.
  • By environment: models usable in explosive atmospheres (ATEX zone 1) are suited to petrochemicals and offshore.
  • By frequency: the number of cycles per day stated in the user instructions must match the pace of the activity.

An integrated energy absorber reduces the forces transmitted to the structure when the load is arrested, and a multi-pawl system limits the distance the load falls.

Standards and regulations for load arresters

A load arrester is not PPE: it protects people and installations around the load, and must never be used to hold a person. It falls under machinery regulations, currently Directive 2006/42/EC. ATEX versions are certified to EN ISO 80079-36 and 80079-37 (non-electrical equipment for explosive atmospheres). Each unit comes with its own declaration of conformity, accessible via the QR code on the label; the user instructions, technical data sheet and inspection guide are in the Documents tab.

Maintenance and inspection

  • Before each use: extend the cable, check locking and the condition of the housing and connector.
  • Periodic inspection by a competent person, using the inspection guide and at the frequency set by the user instructions and the regulations for lifting equipment.
  • After a load has been arrested: withdraw from service until inspected by the manufacturer or an approved repairer.
