A 1-A:10-B:C rated 2.50 lb (1.13 kg) dry-type fire extinguisher is mounted inside the
cab, between the door and the operator's seat.
A single-blade windshield wiper is installed to remove moisture from the windshield.
The wiper is driven by an electric motor that is controlled by a lever on the steering
column. A windshield washer system is installed to spray a cleaning solution onto
the windshield. It consists of two nozzles (one on each side of the wiper arm), a
canister, and pump. The electric pump draws the solution from the canister and
forces it through a hose to the two nozzles that spray it onto the windshield.
The carrier cab also features a hot-water heater and a roof-mounted air conditioning
unit. The cab heater circulates hot engine coolant through a heat exchanger. Hot
air is blown out of the heater into the cab by a variable speed blower motor. The air
conditioning unit is comprised of a self-contained evaporator and condenser coil
unit, a remote engine-mounted compressor, and a control panel which allows the
operator to control temperature and fan speed.

Superstructure Cab Assembly. The superstructure cab contains all controls and
indicators for craning operations and traveling on the job site. The cab is all-steel,
acoustically-treated, and fully enclosed with tinted safety glass windows throughout.
Access to the cab is via a sliding door which features a latch handle and keyed
lock. Grab handrails are provided beside the door opening to aid the operator in
getting in and out of the cab.
The superstructure cab has a skylight with a tinted safety glass window. A
manually-operated skylight wiper is provided to remove moisture from the skylight.
The cab seat is mounted on a track assembly, allowing it to be adjusted to a
comfortable distance from the steering wheel and front console. The seat has a
lever at the front of the bottom cushion to adjust the tilt of the seat back. An armrest
on each side of the seat houses the hydraulic remote controls used to control the
crane functions. The armrests swing up beside the seat and latch in place to make
it easier for traveling and entering and exiting the cab. A safety device in the
armrests disables the controllers when the armrests are in the latched position. In
addition to the safety device in the armrests, a tape switch incorporated in the cab
seat, deactivates the controllers when the operator leaves the seat.
A 1-A:10-B:C rated, 2.5 lb (1.13 kg) dry-type fire extinguisher is mounted in the cab,
under the operator's seat.
A single-blade windshield wiper is installed to remove moisture from the windshield.
The wiper arm is driven by an electric motor which is controlled by a two-speed
switch located on the front console panel. A windshield washer system is installed
to spray a cleaning solution on to the windshield. It consists of two nozzles (one on
each side of the wiper arm), a canister which is located beneath the cab, and a
pump assembly.
