FAQ Topics / Cranes

We have an elevated, one time job in our crowded plant. I have been asked to explore using our 12 ton overhead crane (not the hoist) to connect boatswains’ chairs and retractable lifelines to in order to reach the job site and complete the task. No room for lifts or scaffolds. Any reason we should not do this?

Looks like a plan to me. If you’re bold you can go for the beam trolley; if very bold go for the hook. Condition: all locked out for the lifeline and chair use. Do a drawing to help guide and then recall what you did.

Have you had any experience using an overhead crane beam as an anchor
point. I am working with a client locally and it seems that may be an
option. I have attempted to identify an OSHA letter of interpretation addressing this issue but have not had any luck. Any advice would be greatly appreciated.

I have always recommended an overhead bridge crane as an
anchor point for fall protection below with a few conditions primarily lock-out of the crane controls before lifeline use. You can get to almost every part of the structure in the area of the crane.

First the question of the bridge: no problem adequate welding support is required.

Second the trolley: Again adequate welding support is required.

Third the hook: Some are violently on both sides of the question. There are some OSHA standards and interpretations related to attachment to the
hoist hook 1926.502(d)(23). If lock out is done reliably and maintained then I see no problem and it is quick to install without welding which has its own set of issues.

We work with big stainless steel silo tanks. I’m wondering if we can use our over head crains as a fall arrest for a temparary place to tie off. We are working on another solution, but the crane is our only option for the short term. I understand we need to lock-out tag-out the crane.

In order to use the crane solution required are a written program; a training program with curriculum written; evidence that the training was delivered and to whom. Names of your duly appointed Competent and Qualified Persons must be included in the documentation.
