A National Crane 300C is a telescoping crane mounted on a truck. You drive it to site, set it on outriggers and lift. If a 300C has come into your yard without the book in the cab, or a relief operator is taking over, this manual is the document that sits with the machine and tells the operator how to run it.
What this manual helps you do
- Check the crane before each shift using the inspection and weekly inspection sections.
- Learn the truck cab controls and get familiar with the crane's equipment layout.
- Follow the crane set up sequence before you put a load on the hook.
- Read the rules for operating the winch and how the anti-two-block system works.
- Use the standard hand signals so the operator and the signal person are speaking the same language.
Who this is for
Crane operators, especially a new or relief operator picking up a 300C for the first time. Also owner-operators and hire companies who want the operating rules, crew responsibilities and daily checks on file for whoever is in the seat.
FAQ
Q: What do I receive and how is it organised?
A: One PDF file, 148 pages, in English. It runs from the introduction and safety through inspection, safe operation, controls, set up and system operation, then on to service, trouble diagnosis and the three section boom.
Q: Which machine does it fit?
A: It is for the National Crane 300C truck crane. The title wording on the manual is "300C Series Telescoping Crane Owner's Manual", publication number CTRL037-02.
Q: How does it fit my job?
A: It gives the operator one place to look for the safety rules, the set up steps, winch and anti-two-block guidance, and the routine care like hydraulic oil, tire load and inflation, and rope replacement. Keep it with the crane and hand it to whoever is running it.
Put it in the cab file, and the next operator has the controls, the set up sequence and the daily checks in front of them.
