Gary E. Kilpatrick, PE, DFE is a certified operator for four crane types:

1. The Telescoping Boom Crane Fixed Cab (TSS) also known as a Boom Truck or Neck Breaker. This crane is mounted onto a 30-foot-long flatbed truck and has A-Frame type outriggers and can have rear end stabilizers. This crane is driven by the crane operator over the road to the work destination.
2. The Telescoping Boom Crane Swing Cab (TSS). This crane is referred to as the Rough Terrain (RT) Crane and is also referred to as the Cherry Picker. It has two drive steer axles with large pneumatic tractor type tires. The crane’s cab is offset from the boom and rotates with it. This crane must be mounted to a large flatbed tractor trailer truck and carried to its work destination. This crane uses counter-weights that attach behind the boom and cab on the superstructure. The counter weights must be transported to the crane’s work site on flatbed tractor trailer trucks.
3. The All-Terrain (AT) Crane. This crane can have four, six or eight drive steer axles with large pneumatic tractor type tires. The boom tip can trail the crane’s carrier with a boom dolly to support the lower load block and boom tip. The crane operator must have a Class A CDL to drive this crane over the road. This crane has two cabs, one mounted to the crane’s carrier for driving the machine over the road to its work destination. The other cab is mounted to the crane’s superstructure for crane operations and the cab is offset from the boom and rotates with it. This crane uses counter-weights that attach behind the boom and cab on the superstructure. The counter weights must be transported to the crane’s work site on flatbed tractor trailer trucks.
4. The Lattice Boom Crawler Crane. This crane has bull dozer type tracks below the carrier to propel it around the work site. The superstructure is mounted over the carrier and incorporates the lattice boom and crane cab. The cab is offset from the boom and rotates with it. This crane uses counter-weights that attach behind the boom and cab on the superstructure. The counter weights must be transported to the crane’s work site on flatbed tractor trailer trucks.
