Clark S25C Specifications
The Clark S25C represents a well-engineered solution in
the 5000 lb capacity LPG forklift class, offering a balanced combination of
power, efficiency, and maneuverability. Powered by the FORD 2.5L LPG Tier-4
engine with 69.7 hp, this model delivers reliable torque for lifting and
maneuvering loads up to 5000 lb (2500 kg) while maintaining fuel efficiency
suitable for demanding indoor applications. Its compact design, combined with a
tight turning radius of 81.1 in (2.06 m), allows for excellent maneuverability
in congested warehouse aisles and tight spaces.
The S25C is equipped with cushion tires, providing stable performance on
improved surfaces common in warehouse environments. Operators benefit from
ergonomic features including hydrostatic power steering, an adjustable
full-suspension seat, and hood-mounted hydraulic levers with low input force
that reduce fatigue during extended shifts.
The interactive 5.6" LCD SMART dash display provides real-time diagnostics,
password protection, and audible and visual warnings, keeping operators informed
of service needs. Force-cooled wet disc brakes reduce total cost of ownership
with constant oil flow around the brakes at all times. The fully welded heavy
gauge frame, nested I-beam upright, and 6-roller carriage with external
side-thrust rollers ensure durability and stability.
The Clark S25C is a rider-seated forklift powered by an LPG engine. It has a
load capacity of 5000 lb at a 24 in load centre, equivalent to 2500 kg at a 500
mm load centre. The distance from the drive axle centre to the fork face is 16.1
in or 409 mm. The truck has a wheelbase of 56.3 in or 1430 mm. Its service
weight is 8380 lb or 3801 kg, with axle loadings shifting from 2822 lb or 1280
kg on the front and 5558 lb or 2521 kg on the rear when unladen, to 11,383 lb or
5370 kg on the front and 1997 lb or 932 kg on the rear when carrying a full
load.
The Clark S25C is powered by the FORD 2.5L engine, a
sophisticated four-cylinder LPG power unit known for its reliability, fuel
efficiency, and advanced electronic controls.
The engine is a four-cylinder LPG engine with a displacement of 152 cu in or
2488 cc. It features a 4-cylinder dual overhead cam design, variable valve
timing (VVT), sequential multi-port fuel injection, timing chain-driven
camshaft, and automatic belt tensioners. It produces a rated power of 69.7 hp at
2500 rpm, equivalent to 52 kW at 2500 rpm. The engine meets Tier-4 emission
standards. Some sources indicate a displacement of 141 cu in. Fuel Tank: The
liquid fuel tank capacity is 15.9 US gal.
The engine employs a forced lubrication system. Routine maintenance, including
oil and filter changes, is mandated at specific hourly intervals as outlined in
the periodic maintenance schedule to ensure longevity and performance.
Engine temperature is regulated by a pressurized liquid cooling system with an
open core radiator that reduces engine heat and operates more efficiently.
Regular inspection of coolant levels and condition, as well as monitoring the
radiator, water pump, and hoses for wear and debris, is part of standard
preventative maintenance.
The drivetrain is engineered to provide smooth power
delivery and precise control, essential for maneuvering loads efficiently in
warehouse environments.
Transmission: The S25C is equipped with an automatic powershift transmission.
The transmission and axle are separate, simplifying service and reducing the
length of service calls. The transmission type is HY (hydrodynamic). The
powertrain protection monitoring system alerts the operator when the powertrain
temperature rises, ensuring the truck does not overheat.
Travel Speed: This forklift achieves a laden travel speed of 11.2 mph or 18.1
km/h, and an unladen speed of 11.5 mph or 18.5 km/h.
Axles: The front axle is a drive axle with 2 driven wheels, designed to bear the
majority of the load during lifting operations. The rear axle is a steer axle
with 2 wheels, which pivots to maintain ground contact. Both are robustly
constructed with proven steer axle design.
Brakes: Service braking is handled by force-cooled wet disc brakes, providing
reliable and progressive deceleration essential for safety. A constant flow of
oil around the brakes at all times reduces maintenance and extends lifespan
compared to traditional drum brakes. The parking brake is hand-operated
mechanical type.
The electrical system operates at a standard 12 volts
with an alternator output of 40 amps. The system powers the starter motor,
lights, and electronic control units. The interactive 5.6" LCD SMART dash
display features password protection, audible and visual warnings, and on-board
diagnostics that keep operators informed of service needs, reducing the number
of service calls required to diagnose the truck. The system includes Controller
Area Network (CAN-bus) communication for enhanced diagnostics and monitoring.
The chassis is a heavy-duty, fully welded steel
structure constructed from the highest quality steel that supports all major
components: the engine, drivetrain, counterweight, and mast.
Wheels and Tires: The truck is fitted with cushion tires, which provide stable
performance on improved surfaces common in warehouse applications. The front
tires are size 21x7 inches, and the rear tires are size 16x5-10.5 inches. Some
sources indicate front tires 18x6 inch and rear tires 14x5 inch cushion. The
wheel configuration features 2 driven wheels at the front and 2 steer wheels at
the rear. The front tread width is 34.8 in or 884 mm, and the rear tread width
is 35.2 in or 895 mm.
Steering: The S25C features hydrostatic power steering, which significantly
reduces the effort required to turn the wheel, especially when the truck is
stationary or moving slowly under load. The steering column has an adjustable
tilt range of 30 degrees, allowing operators of various heights and sizes to
navigate the operator compartment with ease.
The hydraulic system powers the lifting, tilting, and
auxiliary functions such as sideshift. The system is designed for precise load
control and efficient operation with optimized hydraulic operating pressure that
reduces overall fuel consumption. It includes a hydraulic pump, control valves,
lift cylinders, and tilt cylinders. Hood-mounted hydraulic levers with low input
force make operation simple and comfortable. The auxiliary function pressure
relief is 2275 psi, with auxiliary function flow rate of 20 gpm maximum.
The forklift can be equipped with various mast types,
including 2-stage and 3-stage masts. The Clark-standard nested I-beam upright
promotes stability and reliability. The standard mast configuration has a
lowered height of 83.3 in or 2115 mm. It provides a free lift of 4.3 in or 110
mm, enabling lifting in low-clearance areas before the mast sections begin to
extend. The maximum lift height is 130 in or 3300 mm, at which point the mast
extends to a height of 151.7 in or 3854 mm including load backrest.
Some configurations offer maximum fork heights of 189 in with 3-stage masts. The
mast tilts forward by 8 degrees and backward by 10 degrees to facilitate load
handling and secure transport. The fork carriage is DIN 15173 Class II with
6-roller carriage design, with carriage width of 37 in or 940 mm. External
side-thrust rollers on the upright reduce rail spreading, helping maintain full
capacity of the mast. The standard fork dimensions are 1.75 in thick, 4.0 in
wide, and 42 in long, which is 45 mm by 100 mm by 1070 mm.
Rated load capacity - 5000 lb or 2500 kg
Load centre - 24 in or 500 mm
The lift speed with a load is 102.4 ft/min or 0.52 m/s,
and without a load, it increases to 106.3 ft/min or 0.54 m/s. Lowering speeds
are 108.2 ft/min or 0.55 m/s with load and 98.4 ft/min or 0.50 m/s without load.
The truck can generate a maximum drawbar pull of 4628 lb or 20,584 N when laden,
and 1724 lb or 7669 N when unladen. Its gradeability is 33.8 percent when laden
and 18.8 percent when unladen.
The overall length of the truck, including the standard
42 in or 1070 mm forks, is 134.4 in or 3414 mm when measured to the fork face.
The length to the face of the forks is 92.3 in or 2344 mm. The overall width is
41.7 in or 1060 mm. The seat height is 43.8 in or 1113 mm, and the coupling
height is 12.2 in or 310 mm. The height to the top of the overhead guard is 82.9
in or 2105 mm.
Ground clearance, laden, is 3.3 in or 85 mm below the mast, and 4.3 in or 110 mm
at the centre of the wheelbase. The minimum aisle width required for right-angle
stacking with 1000 x 1200 mm pallets crossways is 3670 mm, and for 800 x 1200 mm
pallets lengthways, it is 3870 mm. The outside turning radius is 81.1 in or 2061
mm , with an internal turning radius of 21.5 in or 545 mm. The truck's operating
weight, as specified, is 8380 lb or 3801 kg.
