The invention discloses a novel ladder truck. The novel ladder truck comprises a base plate. A support frame is fixed to the base plate. Ladder-like pedals are fixed to the support frame. The bottom of the base plate is provided with rollers. The rollers are prepared from a composite material. The pedals are prepared from an alloy material. The alloy material is coated with a protective layer. The novel ladder truck has good roller wear resistance, mechanical properties and ageing resistance. The pedals have good toughness, high strength, the protective layer, good acid and base resistance, good water resistance and organic solvent resistance.
