Clark GTS30L Specifications
The Clark GTS30L is a 3.0-tonne (6,614 lb) capacity,
LPG-powered, seated rider forklift, engineered for powerful and reliable
performance in demanding material handling applications. As a core model in
Clark's GTS-Series, this forklift is designed for versatility in industries such
as warehousing, distribution, manufacturing, and logistics. Powered by the
durable Mitsubishi 4G64 engine with a PSI fuel system, it delivers responsive
power and smooth operation.
Its robust construction, pneumatic tires, and advanced hydraulic system ensure
productive, safe, and efficient operation. Operator comfort and safety features,
including hydrostatic power steering that eliminates kick-back and
maintenance-free wet disc brakes, contribute to exceptional handling confidence
and reduced operator fatigue.
The Clark GTS30L is a counterbalanced pneumatic tire forklift truck designed for
versatility and safety. It operates on LPG and is controlled by a seated
operator. Its rated load capacity is 3000 kg (6614 lb) at a 500 mm (19.7 in)
load centre. The load distance from the drive axle centre to the fork face
measures 460 mm (18.1 in), and the truck has a wheelbase of 1700 mm (66.9 in).
The service weight of the truck when unladen is 4220 kg (9304 lb). When fully
laden, the axle loading on the front axle is 5740 kg (12655 lb) and on the rear
axle is 1060 kg (2337 lb). When unladen, these figures shift to 1650 kg (3638
lb) on the front and 2570 kg (5666 lb) on the rear.
The main element of the Clark GTS30L is the Mitsubishi
4G64 engine, a four-cylinder LPG unit with a PSI (Power Systems Incorporated)
fuel system. It has a total displacement of 2.4 L (143 cu.in). The engine is
rated to produce 51.6 kW (69.2 hp) at a rated speed of 2650 rpm. The PSI fuel
system ensures precise fuel delivery and reliable starting. The 4G64 engine is
known for its durability and smooth power delivery.
The system is designed to support continuous operation in demanding conditions.
The engine employs a forced lubrication system with full-flow filtration to
protect internal components. Liquid cooling is maintained by a belt-driven
centrifugal water pump and a radiator designed for efficient heat dissipation.
The cooling system is engineered to maintain optimal operating temperatures
during extended use.
Transmission: The GTS30L is equipped with a proven
drivetrain designed for durability and smooth operation. The transmission allows
for smooth direction changes, enhancing operator efficiency and reducing
fatigue. The specific transmission type is not detailed in the source material.
Travel Speed: The forklift achieves a maximum travel speed of 18.3 km/h (11.4
mph) when fully laden and 19.5 km/h (12.1 mph) when unladen. The reverse speeds
are consistent with forward speeds, ensuring reliable maneuverability in both
directions.
Axles and Brakes: The truck uses a drive axle configuration with two driven
wheels on the front (2x2). The service brake system features wet disc brakes,
providing reliable stopping power for both laden and unladen operations. These
brakes offer strong braking effect with minimal maintenance requirements.
The electrical system operates at 12V. The system is
responsible for starting the LPG engine and powering all lights and operator
interface components. The system features moisture-resistant electrical
connectors for durability.
The Clark GTS30L is fitted with pneumatic tires,
designed for traction and comfort on various indoor and outdoor surfaces. It has
four wheels in total, with the front two being the driven wheels. The front tire
size is 28x9x15-14PR (711 mm x 229 mm x 381 mm). The rear tire size is
6.50X10-12PR (165 mm x 254 mm). The front tread width measures 1029 mm (40.5 in)
with variant widths of 1109 mm (43.7 in) and 1204 mm (47.4 in). The rear tread
width is 904 mm (35.6 in). The body and frame are constructed of fully welded
heavy gauge steel for durability.
The Clark GTS30L features hydrostatic power steering that eliminates steering
kick-back, making steering easy and reaching full lock with just a few turns of
the steering wheel. The steering axle has pivotal bearings mounted in rubber
steel elements for durability and vibration dampening. The spherical bearing
mounted short tie rods are adjustment-free and guarantee precise and continuous
driving in a straight line. The double acting steer cylinder ensures precise and
direct steering. A priority distributor ensures steering priority in all
conditions. The mast and fork carriage can tilt forward by 6 degrees and
backward by 10 degrees to facilitate load handling and secure transport.
The hydraulic system is a core component for lift and
tilt operations. It features a full-flow reverse filter that filters the oil to
the tank at each reverse flow, while rough particles are filtered directly via a
suction filter to prevent contamination, ensuring a long service life for all
hydraulic components.
A high-capacity pump provides adequate oil
supply for the upright and the hydrostatic steering. Load handling is
controlled via a load-sensitive and precise control valve. A safety
valve provides extra safety and prevents uncontrolled lowering of the
load at all times. Operating pressure for attachments is not detailed in
the source material, with rated flow for attachments not specified.0
The Clark GTS30L is equipped with a lifting system
designed for durability and visibility. With the mast fully lowered, the height
to the top of the mast is 2180 mm (85.8 in). The free lift, which is the height
the forks can rise before the mast itself begins to extend, is 110 mm (4.3 in).
The maximum lift height for the standard
configuration is 3195 mm (125.8 in), at which point the mast extends to
a total height of 4415 mm (173.8 in) including the load backrest. The
fork carriage is DIN 15173 class III and has a width of 1041 mm (41.0
in) with variant widths of 1143 mm (45.0 in) and 1549 mm (61.0 in).
Alternative mast configurations may be available for different lift
height requirements.
Load Capacity - 6,614 lb (3,000 kg)
Load Centre - 19.7 in (500 mm)
The lift speed for the 3000 kg (6614 lb) rated load is
0.52 m/s (102 ft/min) when laden and 0.56 m/s (110 ft/min) when unladen.
Lowering speed is controlled at 0.54 m/s (106 ft/min) for laden and 0.50 m/s (98
ft/min) for unladen conditions. The maximum drawbar pull, a measure of tractive
effort, is 19200 N (4317 lbf) for a laden truck and 7855 N (1766 lbf) for an
unladen truck.
The overall length of the truck, including the forks,
is 3842 mm (151.3 in). The length from the front face of the backrest to the
fork face is 2772 mm (109.1 in). The overall width of the truck is 1250 mm (49.2
in) with variant widths of 1330 mm (52.4 in) and 1629 mm (64.1 in). The standard
forks have dimensions of 45 mm (1.8 in) thick, 122 mm (4.8 in) wide, and 1070 mm
(42 in) long.
The height of the standard overhead guard is 2180 mm (85.8 in). The seat height
is 1219 mm (48.0 in). The coupling height for towing is 360 mm (14.2 in). Ground
clearance minimum below the mast is 150 mm (5.9 in). At the centre of the
wheelbase, ground clearance is 165 mm (6.5 in).
For maneuvering in aisles, the right-angle stacking aisle width for pallets
measuring 1000 by 1200 mm (39.4 by 47.2 in) with the 1200 mm (47.2 in) side
across the width of the truck is 4135 mm (162.8 in). For pallets 800 by 1200 mm
(31.5 by 47.2 in) with the 1200 mm (47.2 in) side along the length of the truck,
the required aisle width is 4340 mm (170.9 in). The outer turning radius is 2480
mm (97.6 in), and the internal turning radius is 852 mm (33.5 in). The total
operating weight of the truck is 4220 kg (9304 lb).
