Clark S32CL Specifications
The Clark S32CL is a 3.2-tonne (6,500 lb) capacity,
LPG-powered, seated rider forklift, engineered for reliable performance in
demanding indoor material handling applications. As a core model in Clark's
cushion tire line, this forklift is designed for maneuverability in warehouses,
distribution centers, and manufacturing facilities.
Powered by the advanced Ford 2.5L LPG engine
featuring variable valve timing and sequential multi-port fuel
injection, it delivers responsive power while maintaining fuel
efficiency and meeting Tier 4 emission standards. Its robust
construction, force-cooled wet disc brakes, and nested I-beam upright
ensure durability and operator confidence during complex maneuvers with
heavy loads. Proven steer axles and enhanced cooling systems contribute
to productive, safe, and efficient operation in high-capacity indoor
environments.
The Clark S32CL is a counterbalanced cushion tire forklift truck
designed for versatility and safety. It operates on LPG and is
controlled by a seated operator. Its rated load capacity is 3200 kg
(7055 lb) at a 500 mm (19.7 in) load centre. The load distance from the
drive axle centre to the fork face measures 414 mm (16.3 in), and the
truck has a wheelbase of 1430 mm (56.3 in).
The service weight of the truck when unladen is
4429 kg (9764 lb). When fully laden, the axle loading on the front axle
is 6526 kg (14387 lb) and on the rear axle is 1102 kg (2429 lb). When
unladen, these figures shift to 1281 kg (2824 lb) on the front and 3148
kg (6940 lb) on the rear.
The heart of the Clark S32CL is the Ford 2.5L engine, a
four-cylinder LPG unit with a dual overhead cam design. It has a total
displacement of 2488 cc (152 cu.in). The engine is rated to produce 52 kW (69.7
hp) at a rated speed of 2500 rpm. The engine features variable valve timing
(VVT), sequential multi-port fuel injection, and a timing chain-driven camshaft
for precise fuel delivery and reliable starting. Automatic belt tensioners are
incorporated for reduced maintenance.
The system is designed to support continuous operation in demanding conditions.
The engine employs a forced lubrication system to protect internal components.
Liquid cooling is maintained by a belt-driven centrifugal water pump and a
radiator with wider fin spacing and in-line tubes, offering reduced plugging and
increased air flow. Improved hose clamps create a tighter seal, and a high-flow
fan maintains optimal operating temperatures for longer duration. Extended
maintenance intervals up to 500 hours are achievable.
Transmission: The S32CL is equipped with a proven
drivetrain designed for durability and smooth operation. While specific
transmission details are not fully detailed in the source material, the model
features proven steer axles and cooling systems as standard equipment.
Travel Speed: The forklift achieves a maximum travel speed of 18.0 km/h (11.2
mph) when fully laden and 18.6 km/h (11.5 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. The service brake system features force-cooled wet disc
brakes, providing reliable stopping power for both laden and unladen operations.
The proven steer axles enhance durability and performance.
The electrical system operates at 12V. The system
features an on-board dash with the ability to diagnose and clear engine codes
directly, eliminating the need for external laptops or memorizing pedal pump
sequences. The system is responsible for starting the LPG engine and powering
all lights and operator interface components. Moisture-resistant electrical
connectors are incorporated for durability.
The Clark S32CL is fitted with cushion tyres, designed
for traction and durability on smooth indoor surfaces. It has four wheels in
total, with the front two being the driven wheels. The front tyre size is 21x9
(533 mm x 229 mm) and the rear tyre size is 16x6-10.5 (406 mm x 152 mm). The
front tread width measures 926 mm (36.5 in), and the rear tread width is 920 mm
(36.2 in). The body and frame are constructed of fully welded heavy gauge steel
for durability.
The Clark S32CL features full hydrostatic power steering with proven steer
axles. This system reduces the effort required by the operator to turn the
wheels, especially when the truck is stationary or under load. The mast and fork
carriage can tilt forward by 8 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 external side-thrust rollers for smooth upright
operation. Hydraulic system operating pressure is not detailed in the provided
source material, but the 6-roller carriage design ensures reliable performance.
The system supplies the necessary volume for lift, tilt, and auxiliary hydraulic
functions.
The Clark S32CL is equipped with a nested I-beam
upright design for strength and visibility. With the mast fully lowered, the
height to the top of the mast is 2115 mm (83.3 in). The free lift, which is the
height the forks can rise before the mast itself begins to extend, is 115 mm
(4.5 in). The maximum lift height for the standard configuration is 3165 mm
(124.6 in), at which point the mast extends to a total height of 3824 mm (150.6
in) including the load backrest.
Alternative mast configurations may include three-stage masts offering lift
heights up to 6000 mm (236.2 in) or higher. The fork carriage is DIN 15173 class
III and has a width of 1041 mm (41 in). The 6-roller carriage design and
external side-thrust rollers ensure smooth operation.
Rated load capacity - 3200 kg (7055 lb)
Load centre - 500 mm (19.7 in)
The lift speed for the 3200 kg (7055 lb) rated load is
0.43 m/s (84.6 ft/min) when laden and 0.45 m/s (88.6 ft/min) when unladen.
Lowering speed is controlled at 0.47 m/s (92.5 ft/min) for laden and 0.43 m/s
(84.6 ft/min) for unladen conditions. The maximum drawbar pull, a measure of
tractive effort, is 20261 N (4555 lbf) for a laden truck and 7024 N (1579 lbf)
for an unladen truck.
The overall length of the truck, including the forks,
is 3501 mm (137.8 in). The length from the front face of the backrest to the
fork face is 2431 mm (95.7 in). The overall width of the truck is 1155 mm (45.5
in). The standard forks have dimensions of 50 mm (2.0 in) thick, 125 mm (5 in)
wide, and 1070 mm (42 in) long.
The height of the overhead guard is 2105 mm (82.9 in). The seat height is 1113
mm (43.8 in). The coupling height for towing is 310 mm (12.2 in). Ground
clearance minimum below the mast, when the truck is laden, is 85 mm (3.3 in). At
the centre of the wheelbase, ground clearance is 110 mm (4.3 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 3760 mm (148.0 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 3960 mm (155.9 in). The outer turning radius is 2147
mm (84.5 in), and the internal turning radius is 545 mm (21.5 in). The total
operating weight of the truck is 4429 kg (9764 lb).
Routine maintenance is centered on the reliable Ford
2.5L LPG engine and the hydraulic system. Key maintenance items include regular
engine oil and filter changes, hydraulic oil checks and changes, and
transmission fluid checks. The engine features extended maintenance intervals up
to 500 hours, reducing downtime and maintenance costs. The cushion tyres require
periodic inspection for wear. The force-cooled wet disc brake system requires
inspection of fluid levels and component wear.
