Tensology has used Crosby Straightpoint’s (SP) Clamp On Line Tensionmeter (COLT) to measure tension on eight .74in (19mm) diameter ropes that lift a very heavy, 50t capacity elevator at a major UK steel facility. Tensology used the COLT, which measures tension up to 11,000 lbf (lb. force) / 5,000 kgf (kg force) and up to 1 in. / 25mm diameter, to verify that each of the eight newly installed ropes were under the same tension. Any variance would have created a safety issue when the elevator was returned to work delivering materials to different levels of the steel-making factory.

As you’ve seen on our Social Media, we have been discussing the importance of the use of latches with hooks for overhead lifting. 

Crane Operator Crushed Between Two Steel Frames When Rigging Failed
The operator of an overhead crane had been using a chain sling attached to the hook of the crane, and was setting it up into a single choker hitch to pick up and turn over the steel frame, that was lying horizontally on two sawhorses. The hook on the sling did not have a safety latch. The operator was standing between the load and another steel frame that was leaning vertically against the shop platform. The chain disconnected from the hook and the vertical steel frame fell towards him. He was crushed between the two steel frames. [Source: OSHA Case Histories – Rigging Accidents- Case History #7]

A newly formed ASME B30.30 subcommittee has been working diligently to develop a new volume specifically for wire rope, hybrid rope, and synthetic fiber rope. The B30.30 subcommittee consists of approximately 25 individuals with considerable industry experience with lifting components, and equipment usage.
