Forklift for construction and outdoor use
Outdoors, the ground, ramps and dust matter more than the catalogue capacity.
Power
For sites and yards, diesel is usually chosen for power and fast refuelling. LPG is a cleaner alternative if you alternate with ventilated sheds.
Tyres
Air-filled tyres absorb irregularities better and improve grip in mud and gravel. Solid tyres last longer on hard ground but are stiffer.
Ground clearance and ramps
Look at the ground clearance and maximum gradient on the data sheet and compare them with your real ramps.
Engine protection
A large air filter and a good radiator reduce wear in dusty conditions. Ask about maintenance of both.
