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.

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.

"Devil is in the Details"
The CrosbyIP IPSC10 screw style clamp is suitable for use in positioning and turning steel plates and sections. The
pivots (clamp pads) of screw clamps are usually small in size, but actually do all the hard work. When it comes to safety of life and load, CrosbyIP takes care of every little detail of their clamps. The pivots of CrosbyIP clamps undergo a proprietary hardening process, resulting in a strong, yet ductile core and an extremely high surface hardness. To make sure that the pivot keeps the specified hardness and strength, no further surface treatment is done, as this may induce unwanted reactions (such as hydrogen embrittlement).
So, whatever you are lifting or handling, choose CrosbyIP Lifting Clamps

When loads are not properly rigged to the center of gravity, load control and stability suffer; loads and lives are at risk. An eliminator chain sling system can help with this issue, allowing for sling lengths to be adjusted as needed.

Crosby Introduces ROV Release & Retrieve Shackle Line Featuring the Patent Pending Captured Bolt Design
(Tulsa, OK) After years of development and intensive testing by several of the top subsea specialists in the world, the
new Crosby ROV Release and Retrieve Shackles are ready for global release. Featuring an innovative Patent Pending Captured Bolt design, which prevents bolt detaching from the shackle bow, the release and retrieve shackle eliminates the need to have one shackle for releasing a load and one shackle for retrieving a load, and reduces end user liability by eliminating costly post-purchase modifications (i.e., capture barrels, springs, or tether cables). The shackles are available in two different bolt designs: QUIC-Thread (G-2100) and Non-Threaded (G-2110). The QUIC-Thread option requires 60% fewer turns than conventional threaded screw pin type shackles, while the Non-Threaded option touts one of the fastest release and retrieve times in the industry. Designed by the end user for the end user, these best-in-class shackles also feature:
- Forged alloy, galvanized bow with durable API RP 17H color-compliant epoxy finish
- 6 to 1 Design Factor
- Robust captured bolt design - can withstand over 2,000 lbs. of pull-out force
- Galvanized alloy bolt – available in two designs: QUIC-Thread and Non-Threaded
- API RP 17H compliant modular handles available in T, D, F, or Eye versions (sold separately)
- Durable secondary locking latches for added securement
- Eyelets forged into bow for optional tether points
- Monkey Fist(s) included
- Made in the USA
Available in 7 different sizes: 9.5t, 12t, 17t, 25t, 35, 55t, and 85t. These shackles are job site tough and are sure to save you both time and money.
- No costly modifications required (like capture barrels or tether lines), thus reducing end user liability.
- One shackle does it all: releases and retrieves without the need to resurface.
- Both the QUIC-Thread and Non-Threaded bolts greatly reduce the time on the job, saving you costly man hours and vessel time.
