OPERATOR CAB
Description
The Bobcat loader has an operator cab (ROPS and
FOPS) as standard equipment to protect the operator
from rollover and falling objects. The seat belt must be
worn for rollover protection.
Check the cab, mounting, and hardware for damage.
Never modify the cab. Replace the cab and hardware if
damaged. See your Bobcat dealer for parts.
ROPS – Roll-Over Protective Structure per ISO 3471 and
FOPS – Falling-Object Protective Structure per ISO
3449, Level I. Level II is available.
Level I
Protection from falling bricks, small concrete blocks,
and hand tools encountered in operations, such as:
motorway maintenance, landscaping, and other
construction sites.
Level II
Protection from falling trees, rocks: for machines
involved in site clearing, overhead demolition, or
forestry.
Never modify operator cab by welding, grinding,
drilling holes or adding attachments unless
instructed to do so by Bobcat Company. Changes to
the cab can cause loss of operator protection from
rollover and falling objects, and result in injury or
death.
