According to ASME B30.5, which type of crane must have seat belts provided?

The requirement for seat belts in specific types of cranes is intended to enhance operator safety, particularly in situations where there may be increased risk of tipping or sudden movements. The mention of single control station wheel mounted cranes reflects the unique operational characteristics and stability challenges faced by these machines.

Single control station wheel mounted cranes are designed for operation on public roads and varied terrain, which makes it critical for the operator to be secured while driving or operating the crane. Seat belts help prevent the operator from being thrown from their seat in the event of a sudden movement, contributing significantly to safety during operation.

In contrast, other types of cranes listed generally operate in different environments or have design features that inherently reduce the need for seat belts. For example, mobile cranes and rough terrain cranes can also present safety risks, but their design and operation usually incorporate other safety measures. Static tower cranes, on the other hand, are stationary and operate from a fixed position, which may eliminate certain risks associated with mobility. Thus, the specification of seat belts for single control station wheel mounted cranes reflects a targeted approach to enhancing safety for those specific operational conditions.
