The truck extension set is an interesting way to transform the truck into a tank truck or a fire department ladder truck and to build a trailer. The tank truck features an opening mechanism that fits a 0.33 l can. The extendable 3-part fire ladder on a rotating chassis has a length of approximately 70 cm when fully extended. The truck trailer consists of a wheeled chassis on which the truck bed can be mounted. After assembling the extensions for the tank truck and ladder truck, these are mounted on the truck, with the truck bed needing to be removed first. The truck bed can then be mounted on the chassis to create a trailer. With 3 trucks, a complete fleet of 3 vehicles can be assembled: one truck with a flatbed, one truck as a tank truck, one truck as a ladder truck, and one trailer. The ladder truck has several control modes; by repeatedly pulling the lever, the ladder can be raised. The handle allows the ladder to be turned to the right or left. A special ratchet secures the ladder in the desired position, allowing it to be fully extended. At the end of the ladder, there is a hook to use it like a crane. Like a large fire truck, this model also features a small ladder on the side, enabling the firefighter to quickly climb onto the truck. The trailer has realistic leaf spring suspension that absorbs shocks during travel. Under the drawbar, the trailer has a stand, allowing it to be parked independently of the truck. The model is assembled without glue. Please note: The UGM-11 truck is not included.
