The National Crane 400B is a telescoping truck crane. It drives to site on its carrier, sets up on outriggers, and lifts with a telescopic boom. This manual is for the operator who just took over the crane, or the one who needs the control layout and setup sequence in front of them before the first lift.
What this manual helps you do
- Learn the crane controls and what each one does before you pick up a load.
- Follow the safety rules, operating precautions and signalmen's responsibilities on the job.
- Check the equipment before making the lift, including the anti-two-block system and winch rules.
- Plan transport of the truck and crane safely, from travel to arrival on site.
- Inspect the crane on the monthly schedule and read the tire load and inflation table.
Who this is for
A crane operator uses it to learn the controls and run the pre-lift checks the same way each time. An operator trainer uses it as the reference for teaching safety, training and lift preparation to a new hand.
