Introduction
Slewing variable-reach trucks (as defined in ISO 10896-2) are known by a variety of terms including
“rotating telehandlers” and “multi-purpose rotating handlers”.
For unique applications, these trucks can be equipped with a variety of attachments (for example, jibs,
winches, jibs with a winch and clamp, mowers and sweepers).
Users need to take into consideration that certain features and characteristics of these trucks are
unique and require specific methods for use and training of operators. In addition to general user
requirements, these specific methods are also covered in this document.
