Please note container delivery by flatbed, low-boy (low-bed) trailer, or chassis requires a forklift or crane at the delivery site. Alternatively, you can arrange for pick-up at Interport using a trucking company of your choice.


    How should I prepare the ground for delivery? arrow

    A 20-foot container requires 60-feet of straight running room (no bends), 12-feet wide. A 40-foot container requires 120-feet of straight running room for delivery by tilt-bed truck (no bends), 12-feet wide. For the height, a minimum of 14-feet of overhead clearance is needed for containers on a chassis/tilt-bed or on a low-bed (low-boy) so as not to hit wires, etc. If the trucking company cannot make delivery, customer will be responsible for all related trucking and transportation costs.
