Bill,

Articulated trucks are great but don't fall for the B.S.
A 1600mm aisle might be theoretically possible using sideshift and a bit of shunting but you are better to go for wider aisle for better efficiency and a truck that has the right shape like the Flexi which has no corners to hit the racking. Specified correctly with a good truck there is less damage and greater speed than with a reach truck. It is people trying to squeeze the aisles too tight that gets articulated a bad name. It is a good policy to use the BITA GN9 standard - i.e. 100mm clearance each side.
