Product questions
What does the base price include?
The base configuration uses mechanical control. Wireless remote control, proportional control and load-moment equipment are optional upgrades. Tax, freight and destination charges are excluded.
Is the class designation the lifting capacity at every radius?
No. WT12.0 is a 12 t class machine with a listed rated load of 12 t at 2.3 m. Capacity changes with reach, boom and outrigger configuration. Request the applicable load chart before selecting a machine.
Can the crane work indoors?
The listed electric motor can be used where the required three-phase supply is available. Check door width, transport height, floor rating, ventilation and outrigger loads before planning an indoor lift. Do not run a combustion engine in an enclosed working area.
Can you quote delivery to my country?
Yes. Send the destination country and port together with the required configuration. The quotation confirms equipment price, tax treatment, packing, freight, engine documentation and delivery arrangements.
How are optional configurations confirmed?
Select one control package and one load-moment package, then any compatible additional options. Remote-dependent packages require remote control. Changes to the engine or boom are confirmed with a revised specification and load chart before ordering.
