On-site portable line boring
Line boring is a common technique used on large structures such as harbour cranes. It is a
machining technique used to enlarge an existing hole. A hole may be
worn-out for example, making that part of the crane non-functional. We can carry out this kind of work while modernising or repairing the harbour crane.
Line boring using a unique welding method
In cooperation with welding engineers, Liftcom has developed a welding method that allows welding up shaft holes with a welding robot in outdoor locations without using mixed gas. A major advantage over electrodes is that welding in can be performed faster, better and smoother. Moreover, weather influences, such as wind and rain, play a smaller role when using this welding method.
We can apply the following line boring techniques:
- Longitudinal line boring: we are going to drill a deeper hole using the existing hole. The existing circle remains the same size in diameter.
- Flat line boring: we are going to widen the existing hole. The existing circle becomes larger in diameter, but not deeper.
The benefits of our services
- Range - between 150mm and 450mm diameter standard, larger upon consultation;
- Accuracy - any tolerance required;
- Deployment - anywhere in the world.
How do we proceed with line boring?
1 – Determining the desired size of the hole to be bored;
2 – Setting up the portable line boring drill tool;
3 – Broach the existing hole.
