Adjusting Crane Roller Rocker Arms: A Step-by-Step Guide

If you work in the construction industry, you know how important it is to keep your equipment in top condition. One crucial part of a crane that requires regular maintenance is the roller rocker arms. In this article, we will guide you through the process of adjusting your crane’s roller rocker arms, step by step.

Before starting, it’s important to understand what roller rocker arms do. They are responsible for converting the linear motion of the crane’s boom into rotational motion at the load. Properly adjusted roller rocker arms ensure that your crane operates smoothly and efficiently.

Here are the steps to adjust your crane’s roller rocker arms:

  1. First, read the manufacturer’s instructions carefully. Every crane model is different, so it’s important to follow the specific guidelines for your machine.
  2. Remove any panels or covers that may be in the way of the roller rocker arms.
  3. Check the bearings and bushings for signs of wear or damage. If they are damaged, replace them with new ones.
  4. Adjust the tension in the cables according to the manufacturer’s instructions. This can be done using a cable tension gauge.
  5. Make sure that the roller rocker arms are properly aligned with the crane’s boom and counterweight.
  6. Test the roller rocker arms by moving the load through its range of motion. If there is any resistance or uneven movement, adjust the cables accordingly.


By following these steps, you can ensure that your crane’s roller rocker arms are properly adjusted and functioning at their best. This not only extends the life of your equipment but also improves safety on the job site. Remember to always follow safety protocols when working with heavy machinery.
