Crown Equipment Cushion Tire Lift Trucks MAX50 - Manual (Page 5)

FUEL SYSTEM
Gasoline, LPG, or Dual-Fuel systems are
available. The gasoline fuel tank is integral to
the truck frame.
• In-tank mounted gasoline fuel delivery
pump, fuel-level sensing unit, pressure
regulator and fi lter are standard.
• LPG fuel system uses single-point, throttle
body fuel injection. A removable 33 lb.
fuel tank is available with a fold back tank-
mounting bracket.
COOLING SYSTEM
The high-capacity aluminum radiator is
designed with an effi cient thermal transfer
fi n and integral oil cooler for the transmis-
sion torque converter.
• High-volume cooling fan uses fl exible plastic
blades and shroud for maximum air volume
and noise abatement.
ELECTRICAL SYSTEM
Standard instrument package and operator
conveniences:
• 12-volt electrical system
• 50A alternator with built-in IC regulator
• Key-lock, anti-restart ignition switch
• High-torque, low-amp starter motor with
planetary gear reduction
• Waterproof electrical connectors
• Electric fuel gauge, water temperature
gauge, LCD hour meter
• Indicator lights for Neutral/Return to
Neutral, Low Oil Pressure, Low Battery/
Alternator Output, Check Engine Warning,
Hydraulic Lock (Operator Presence), and
ECCS Status Code
• ECCS Service Support Tool connector for
rapid system diagnostics
HYDRAULIC SYSTEM
The Hydraulic System features an integral
reservoir, direct drive gear pump and fully
fi ltered system.
• Large hydraulic fl uid reservoir integral to
the truck frame reduces heat buildup in
the system.
• Load sensing valve in the hydraulic circuit
reduces the fl ow of oil to the power steer-
ing system when steering wheel is idle.
FRAME
An all-welded assembly with heavy-gauge
steel and integral hydraulic and fuel tanks
provide exceptional durability.
• Welded front cross-member and bolted
drive axle increase frame rigidity.
• Loads are transferred directly from the mast
to the drive axle and onto the fl oor without
being transmitted through the frame,
reducing frame stress.
• Wide, open step is designed into the
frame assembly without compromising the
structure.
DRIVE AXLE
A heavy-duty, cast steel drive axle housing
supports the load and chassis without placing
a load on the free-fl oating axle shafts.
A fl ange is mounted to the truck frame to
improve load distribution and reduce
frame fl exing.
TRANSMISSION
Hamech single-speed, powershift transmis-
sion is specifi cally designed for industrial
applications.
• Column-mounted electrical shift lever gives
the operator easy directional control without
removing a hand from the steering wheel.
• Optimized stall ratio for torque converter
provides high torque without sacrifi cing
travel speed.
• A modulating control valve absorbs initial
pressure spikes during initial engagement
and directional change. This improves shift-
ing capabilities and prolongs the life of the
entire drive train.
• Transmission oil is double-fi ltered by a 125-
micron mesh on pickup, and a 35-micron
cartridge on the return line.
• Transmission oil cooler is integral with
the radiator.
• Inching control and auxiliary brake pedal
combination allows the operator precise
truck positioning with positive control.
BRAKES
Hydraulic brakes are self-energizing and
self-adjusting.
• Brake fl uid reservoir is located under the
console cover for fast, easy inspection and
maintenance.
• Heavy-duty brake backing plate and thick
brake drum provide reliable braking action
and reduced heat.
• Mechanical parking brake has two-stage
latching mechanism for positive engagement.
STEER AXLE
Fully Hydrostatic Power Steering is standard.
• Heavy-duty fabricated steer axle has dou-
ble-acting, double-ended power steering
cylinder and no drag links or tie rods.
• Steering stops are machined into the
steering cylinder to reduce stress impact
on steering linkages.
• Grease fi ttings on all linkages are acces-
sible without lifting the truck.
MAST, CARRIAGE, LBR AND FORKS
High-visibility mast assembly has a 4-roller
carriage that is available in two-, three-, and
four-stage Free Lift, Free View designs.
• Sealed bearings require no maintenance.
• Angle-mounted bearings and a shaped rail
fl ange prevent excessive wear and friction,
while maintaining correct side thrust
clearance.
• ITA Class II carriages accept a variety of fork
sizes and common load-handling attachments.
• 48-inch-high load backrest is standard for in-
creased load control and operator protection.
• Single or double auxiliary hydraulic-function
internal hose routing is available.
OPERATOR COMPARTMENT
A unique suspension compartment isolates
the operator from the fl oor surface and from
engine vibration, for greater operator
comfort and productivity.
• Comfort seat has built-in lumbar support,
retractable seat belt, lateral restraint sys-
tem, and fore and aft adjustment.
• Hydraulic control levers are positioned for
optimum access and ease of use. Inter-
national symbols on the contoured grips
indicate the function.
• Tilting steering console has small-diameter
steering wheel and electronic instrumen-
tation. Tilt is infi nitely adjustable, with
extended room between the engine cover
and console.
• Wide-open fl oorboard has suspended
brake and inching pedals with ribbed rub-
ber pads for comfort and safety. Integral
accelerator mechanism has a transfer roller
for smooth operation.
• Full-width rubber fl oor mat provides a
large, non-slip surface and reduces noise,
vibration and heat.
• Open step in the frame with a traction
surface and a large handgrip provide easy
entry and exit for the operator.
• Standard headlight/turn indicator control
lever is mounted on the steering column
for easy use.
• Full-width overhead guard provides excel-
lent visibility for high stacking and meets or
exceeds ITSDF requirements.
SERVICEABILITY
The engine and transmission can be easily
accessed for daily inspection without the use
of any tools.
• Single-piece, all-steel engine cover and
seat support is fully insulated to reduce
noise and heat transfer.
• Engine cover has gas-fi lled cylinder with
an automatic locking device to assist in
opening and to prevent the cover from
unexpectedly closing.
• Engine cover is shaped for easy access
into the engine area for maintenance
and service.
