The Franna AT-20 is an articulated pick and carry crane. It lifts a load and drives with it, no outriggers needed to set up. If you're taking on a used AT-20 that arrived without any paperwork, this full manual set puts every document for the machine in one download, so you can start work instead of chasing single books.
What this manual set helps you do
- Operate the crane using the operator manual, which covers the instrument panel, controls, service intervals, recommended lubricants and the weekly lubrication points.
- Order parts from the parts manual, which has exploded views and part numbers for assemblies like the boom assembly kit, hydraulic plumbing and the electrical assembly.
- Repair the boom, extension cylinders and fall block with the service manual, including the hydraulic service sections and the manual extension setting.
- Trace faults through the schematics, which hold the hydraulic and electrical drawings.
- Verify load charts and inspection forms before a machine goes back out on hire or on site.
Who this is for
A workshop or service company taking on an AT-20 will get the most from it. You get repair procedures, parts breakdowns and drawings for the same machine in one place. Rental fleet managers use it the same way, with one set for operators, mechanics and the parts desk.
