collision avoidance systemAl, a CMCO distributor salesman, trainer and recent safety webinar attendee, asks the following question about applying a collision avoidance system:

Does the age of a crane prevent it from having a collision avoidance system installed? 

Jon Walters, Magnetek trainer and safety webinar presenter, answers:

No. The age of a crane has no impact on whether a collision avoidance system can be incorporated, but there is some basic information that should be considered to ensure it is applied correctly.

Control voltage:

Confirm the necessary control voltage needed so the collision avoidance system can be matched to the existing control voltage. This ensures major changes will not be needed to existing crane control logic.  Magnetek’s collision avoidance systems are designed to operate with control voltages of 12-240 VAC or VDC.

Type of existing crane control:

Is it a contractor control, static stepless control or a variable frequency drive? Determining the existing control scheme defines how the output(s) from the collision avoidance system will be incorporated into the existing control logic. Older cranes may be operating with contactor controls, but still permit the installation of collision avoidance systems.

Type and number of crane motions:

What crane motions will collision avoidance be applied to?  Motions may be:

  • Bridge to obstruction (such as a wall or no-go area)
  • Bridge to bridge
  • Trolley motion to end of travel on bridge
  • Trolley to trolley

The number of motions, along with any “no fly” zones, will determine the number of collision avoidance systems needed.

Distance:

The distance at which a collision avoidance system will “trigger” is determined based on the distances and speeds of the traverse motions in accordance with what is deemed safe for a slowdown and stop function.

The above factors will help determine the configuration of a collision avoidance system that can be added to your crane, which, again, may be implemented regardless of crane age.

We recently received the following question on chain inspection from Slade, a utility crew supervisor working for a water district:

“I was wondering if you carry a “no-go gauge” for Columbus McKinnon chain to inspect gouges, nicks and stretching on the links. Our warehouse personnel struggle to determine the correct gauge for your chain.”

Perry Bishop, our technical trainer, answers: 

We receive this question on chain inspection often, so we thought it would be worthwhile to write a blog to explain the gauges we offer and identify which gauge is the most suitable for the type of chain in question.

For our electric, pneumatic, hand chain hoists and lever tools, we have the following go/no-go gauge:

Go/no-go gauge for CM’s hoist load chain

It is made for CM’s load chain only, such as Star and Disc Grade, and should only be used to measure that style of chain. You can purchase this gauge from your local CMCO distributor under the part #3191.

To find a distributor in your area, simply visit www.cmworks.com and click on the “Find a Distributor” button on the right-hand side of the page.

For our Herc-alloy 800 & 1000 rigging chain (alloy chain slings only) we have the following wear limit rigging chain gauge, part #CWGC.  It is used to check below the hook chain such as HA-800 and HA-1000.

Rigging chain gauge

You can request a rigging chain gauge for free by sending an email to: cmco.live@cmworks.com along with your name, company and mailing address.

A common mistake that happens quite frequently in our industry is that individuals use the wrong gauge on the wrong type of chain. Always ensure you are using the correct gauge and follow instructions on the gauges for proper measuring techniques.

Are Your Shackles Safe for Overhead Lifting?

September 21, 2016






When determining the best shackle for your lifting application, there are many options to choose from. Shackles are typically available in two styles: chain style and anchor style. Chain shackles are best-suited for straight line, single connection pulls because of their U-shape. Anchor or bow shackles have a more generous loop. This allows them to be side […]
