• Two limit switches are installed to automatically cut off the motor power when the crane reaches its forward or aft limits.
• Mechanical Stoppers are fitted at the forward and aft ends of the crane rails. They act as a failsafe to prevent the crane from damaging the forward and aft bulkheads or casing if the limit switches fail. Rubber or spring buffers may also be added to absorb impact forces and reduce the risk of damage.

• Inspect the crane, rails, mechanical stoppers, and support brackets for wear or damage.
• Ensure limit switches are functional and properly aligned.
• Check the condition of the gear case oil and renew it as required.
• Inspect and maintain wire ropes and safety latches.
• Ensure the Safe Working Load (SWL) is clearly marked and adhered to.
• Verify the validity of the crane's test certificate.
• Perform motor overhauls and measure insulation resistance.
• Conduct brake tests and emergency stop function checks.

Provide instructions to Junior Engineers:

• Not exceeding the SWL of the crane.
• Ensuring mechanical locks are removed before operating the crane.
• Using proper Personal Protective Equipment (PPE).
• Prohibiting personnel from standing beneath the crane during operation.
