One of the perceived drawbacks of rear-mount aerial devices is that when positioning the rig, you can lose the length of the vehicle when placing the truck in the front of the fire building due to the turntable being at the rear of the truck. This can be overcome by positioning the center of the turntable with the middle of the objective that you are trying to reach. This will allow for the maximum scrub area on the front of the building, without having the truck block critical access for other incoming units. There are significant operational and placement considerations between the midship- and rear-mounted aerial devices and the truck committee should carefully review these before setting out to develop the specifications for your new truck. If the operational considerations between midship and rear-mounted aerial devices are not fully understood, there are training classes available that can help educate your truck committee on the significant differences that exist.
In the next installment of The Apparatus Architect we will discuss aerial ladder truck design considerations that you may wish to include in your specifications. Knowledge of the components and how they relate to the overall design will help you in developing a comprehensive set of specifications for your next ladder company apparatus.
