Final answer:
Special-purpose forklifts include the Telescopic Handler Forklift and the Rough Terrain Forklift, designed for tasks that require extra reach and for operation on uneven surfaces, respectively.
Step-by-step explanation:
There are several types of forklifts used in various industries, each designed for specific tasks and environments. While there are many forklift classifications, when it comes to special-purpose forklifts, the types often referred to are the Telescopic Handler Forklift and the Rough Terrain Forklift. The Telescopic Handler Forklift, also known as a telehandler, is designed with a boom and extendable arm, making it suitable for jobs that require a reach, such as in agriculture or construction. The Rough Terrain Forklift is built with large pneumatic tires and a powerful engine, which allows it to operate efficiently on uneven ground and outdoor settings.
These special-purpose forklifts are typically found in environments where standard forklifts are not suitable. Their design incorporates hydraulic and mechanical lever systems to enable them to handle heavy loads, as depicted in figures referencing heavy machinery like backhoes.
