Evaluate the condition of your slings

Some slings such as chain slings and metal mesh slings can be repaired when defects are found. Repairs should be performed by the sling manufacturer or an equivalent entity. Until a repaired sling has been fully tested and approved by a qualified person, it should not be put back into service.

Konecranes inspectors and technicians can inspect the slings and other rigging equipment in your facility to determine if it meets OSHA standards. The Konecranes Slings and Accessories Inspection checks non-maintainable load lifting attachments and accessories to identify deficiencies and deviations from local statutory safety and health regulations. The inspection service utilizes radio frequency identification (RFID) tags to record load lifting attachment inspection data and a smartphone app to help quickly and reliably identify attachments.
