COVID-19 Update - The Rowland Company is open to support you.


Our customer is a large shipyard operating over 400 cranes and the operation is over 100 years old. A number of these cranes and brakes are now obsolete. This makes maintenance extra tough.

They had one brake which required continuous attention and still couldn’t meet the current requirements. They turned to us for a solution.


A careful review of the application revealed that the biggest challenge was a lack of space. A tight envelope eliminated most of the current brake designs.

After researching a significant number of designs, we came up with a caliper disc hoist brake for the application. This approach with a disc brake provided increased torque and thermal capacity. Its compact design allowed us to meet their envelope restrictions.

By upgrading the hoist brake, the yard will be able to use this crane well into their next 100 years.
