Adjustments of crane brake bands

Adjustments of crane brake bands, another interesting job done in shipyard after vessel departs from dry dock.

Nowadays I revising my old article and I remember my experiences on board commercial or offshore vessels as hydraulic troubleshooter.

About brake bands job

During my attendance on the vessel for brake band adjustments, I had the opportunity to work together with a senior colleague and learn valuable troubleshooting tips. Specifically, I gained a better understanding of how hydraulic systems work and how to adjust various types of hydraulic equipment.

In most cases, after a vessel departs dry dock there are usually some pending jobs that still need to be completed. Unfortunately, in this case, the cargo cranes were left unchecked due to time limitations during the dry dock period.

So..we had to do a crane inspection and adjustments of crane brake bands.

First, we made a visual inspection of the crane then checked the crane operation.

We found some problems on the brakes. We had to troubleshoot the brake for luffing and hoisting winch.

For luffing winch, the brake bands were worn out. However, we had to adjust the brake bands until it could install new ones.The parameters indication were wrong – the mechanical device was in the wrong position.

I proceeded according to technical book and adjusted the brake. All the times I use the guidance of the manual of the equipment and I recommend it.

The problem with adjusting of crane brake bands is access work. The access work for this mechanical job is limited like all the cranes, space is very narrower, is grease all over the place and is slippery.

Adjusting the crane brake requires two people.. One man is operating the crane joysticks and the other one is riding the winch adjusting the brake.

Note: If the brake bands are worn out, attempting to adjust them would be useless
