Demag ATT 400-3L All Terrain Crane Operator Manual

The Demag ATT 400-3L is a multi-axle all terrain crane. It drives to site on public roads, then sets up and lifts with its telescopic boom. If a used crane came in without the book in the cab, or a relief operator is taking over, this operator manual is the document that goes back with the machine.

What this manual helps you do

• Learn the driving controls and instruments, so a new operator can find every switch and warning light.
• Follow the safety rules before setting up on outriggers and starting a lift.
• Plan the setup sequence, from preparing for travel through to counterweight and rigging.
• Read the load charts and load moment limiter information before working the boom.
• Check the daily maintenance points and carry out the lubrication and care the operator is responsible for.

Who this is for

A crane operator uses it to get familiar with the controls and the working routine on this machine, especially when taking over a crane they haven’t run before. A fleet manager keeps it on file so every ATT 400-3L has its operating rules and daily checks documented.
