A LARGE HYDRAULIC HOSE HAS COME OFF YOUR CRANE AND A LOT OF OIL IS LEAKING. YOU SHUT OFF THE ENGINE DIRECT – BUT WHAT´S NEXT TO DO? 

A SECURITY CHECK OF THE CRANE AND RIGGING HARDWARE MUST BE PERFORMED REGULARLY BY THE CRANEOPERATOR. HOW OFTEN?

YOU WILL HELP A FEW BLACKSMITHS TO LIFT DIFFERENT STEEL STRUCTURES. THEY WANT YOU TO USE SOFT STRAPS / TEXTILE FIBER SLINGS. HOW DO YOU DO?

YOU HAVE HUNG A TWO-LEG CHAIN GEAR IN THE HOOKBLOCK AND YOU SEE THAT THE CHAINS HAVE DIFFERENT LENGTHS. WHICH IS THE MOST LIKELY CAUSE?

WHY IS IT IMPORTANT TO HAVE GOOD ORDER ON YOUR LIFTING GEAR?

WHAT IF THE HYDRAULIC HOSE FOR THE BOOM CYLINDER BREAKS IN THE MIDDLE OF A LIFT SO THAT THE CRANE LOSES HYDRAULIC PRESSURE?

IT’S TIME TO LUBRICATE THE CRANE. DOES THE TELESCOPIC BOOM ALSO NEED TO BE LUBRICATED?

WHICH OF THE FOLLOWING IS THE MAX LOAD / WIDTH  YOU CAN LIFT WITH THIS GEAR
?

A LIFTING GEAR WITH A KNOT ON IT IS PROHIBITED TO USE . BUT WHY? WHAT APPLIES FOR A TEXTILE FIBERSLING?

WHICH OF THEESE CONDITIONS WILL DRAMATICALLY AFFECT THE VALUES ON ANY CRANE LOADCHARTS?
