Disassembly and assembly of milling shafts quickly and safely.

Disassembly and assembly of milling shafts quickly and safely.

The disassembly or assembly of mill shafts is a common operation in sugar cane mills, generally done to maintain shafts that suffer constant wear due to the aggressiveness of the process.

This operation is considered risky, as it is an axle that has a weight that can vary from 10 to 40 tons and is moved most of the time by crane without standardized devices.

The milling shaft has its center of mass displaced and without an appropriate device, the risk of accidents increases a lot.

Know what these risks are?

Breakage of the steel cable due to wear caused by contact with sharp corners of the milling shaft. Improper catch and prohibited by the rules.

When the shaft is moved with the gear still in place, the center of mass is displaced and the load may tilt, significantly increasing the risk of accidents.
In plants in general today, the transom-type devices used were not designed with the center of mass in mind, and do not have documentation.

A shaft grip with an inadequate device can cause an accident. It is very common today to use a single device to move different sizes of milling shafts even without knowing the capacity limits of the device.

Handle made on shaft ends or on smooth surfaces with cable inclined beyond the 45° “allowed by standards”.

Lack of training/qualification of the operator who will handle the handle. The operator must know the rules, he must know how to evaluate the wear on the accessories used for the handle.
Every accessory used must have an identification plate with the project number, inspection date, and manufacturer identification.

If you see the need for an assessment of your operation, we at Movequip are available for a technical visit, or even for a virtual meeting where we can help you with solutions designed to eliminate the risks in this type of operation.
