Abstract: The present invention relates to an aerial ladder truck to allow the height of a rear end of an extensible ladder, which is a connection end thereof connected at the rear of a bed of the truck, to be freely adjusted so that articles may be loaded in a space below the extensible ladder and above the truck bed.
Abstract: The present invention relates to a self-propelled type crane that has outriggers, provided at both ends of the front area and both ends of the rear area of the vehicle body, inclined downward from the top to the outside, thereby helping simply manufacture each outrigger with one cylinder, helps prevent each outrigger from falling down while the crane is operated to lift heavy loads, reduces electrical loss by operating only one of the electric motors and one of the hydraulic pumps when a small amount of power for operation is needed, and increases power output by using both the two electric motors and the two hydraulic pumps when a large amount of power for operation is needed.
