Lifting point
Also known as: lifting lug, attachment point
In machine safety, a lifting point is a designated location on a machine or part intended for the attachment of lifting equipment. It is designed and rated for the loads it has to carry.
- Machine safety
- Technical documentation
In one sentence
A lifting point is a designated, rated location for attaching lifting gear, and it only works as intended with the stated method and angle.
Example
An injection molding tool has four marked threaded holes for eyebolts; the instructions give the eyebolt size, the maximum sling angle and warn that the housing flanges are not lifting points.
How it applies
- Machine safety: Loads fall when people improvise attachment points. Designate lifting points for every configuration that must be lifted, including heavy parts removed during maintenance.
- Technical documentation: Mark lifting points on the machine and show them in the instructions with the mass, the center of gravity, permitted sling angles and required accessories. A safety sign or marking at the point helps.
- Maintenance: Lifting points can corrode or be damaged. The maintenance manual should say how to check them before use.
- Evidence: Design calculations or load tests show the rating of each point.
Lifting point vs. safe handling
A lifting point is a feature of the machine. Safe handling is the method that uses it, together with the right equipment, people and sequence.
