What should be marked on the machine when using an excavator to lay pipes in a trench?

When using an excavator to lay pipes in a trench, marking the Standard Weight Limit (SWL) on the machine is crucial for safety and operational efficiency. The SWL provides operators with the maximum load that the excavator can safely lift or handle without risking structural failure or tipping. This is especially important in situations where the machine may be handling heavy pipes, ensuring that the operator does not exceed the safe working limits.

Additionally, maintaining awareness of the SWL helps in planning lifts and selecting appropriate equipment or attachments, thus preventing accidents or damage to the machine. Understanding and adhering to the standard weight limits is a fundamental part of safe excavator operation, especially in environments where loads are being moved and stability is a concern.

In contrast, while the weight of the machine, total depth of the trench, or the number of pipes being installed may be important operational details, they do not directly relate to the safe lifting and handling limits of the excavator itself. Therefore, these other details are not as critical to the safety and functionality of the machine in the context of laying pipes.
