UGears Fire Truck Wooden Model Kit. UGEARS. The UGears Fire Truck Wooden Model Kit is a beautifully designed and ingeniously engineered self-propelled wooden model. It's fun to build and operate, and functions just like a real life fire and rescue truck complete with ascending ladder that transforms into a crane with hook! When fully extended, the retractable 3-section ladder is 70cm in length. Turn it to the right or to the left, or press the lever to lift it up and down!
