Refuel International manufactures high lift hydrant carts to service wide body aircraft. The carts are high flow performance with a balanced venturi system that ensures the maximum flow through the aircraft-fuelling adaptor. The total parked height of the cart is 54 inches; with the platform extended, the floor working height above ground is over 150 inches. This unique boom permits the platform to be lowered to the ground with the hoses still connected to the aircraft without fuel interruption.
