National Crane Service

Prerequisites:

Shall have successfully completed the Mobile Hydraulic and Mobile Electrical modules of the E-Training program.

Content:

This program assumes no basic service and operational knowledge of National Boom Truck crane systems. We start the course with an in-depth review of boom truck terminology and technologies so the students can relate to individual components and systems.

Programs covering the National load charts are used to expose the students to how load charts are constructed and how to properly read and interpret them. Load moment indicating systems operation and function will be covered with an emphasis on proper use, programming, and how the system functions.

Sessions on National hydraulic and electrical systems will expose the students to schematic layout and symbols with focus on individual circuits as to their purpose and function within the overall system. This will give students a working knowledge of a fully functioning National crane and the foundation to learn proper troubleshooting techniques and test procedures.

Machine hands-on sessions will allow the students to experience how National boom trucks function, proper set up and operation, hydraulic and electrical component identification and troubleshooting task and techniques.

The final portion of the course will be focused on proper Machine Maintenance techniques along with proper use of Machine Delivery Forms and Maintenance Inspection Forms.

Benefits:

Upon course completion the student will be able to:

• Have the basic understanding of how to read and interpret load charts and explain them to operators during machine deliveries.
• Have an understanding of operation and setup of a National crane and understand proper programming and operation of the LMI systems.
• Have a full understanding of National hydraulic and electrical symbols, components and schematics.
• Troubleshoot possible crane system problems by utilizing hydraulic and electrical schematics and service manuals.
• Perform and report basic maintenance and inspections using procedures recommended by the manufacturer.
