Clark C25L Specifications
The Clark C25L is an LPG-powered forklift that delivers
a compelling balance of power, efficiency, and versatility for general material
handling operations. Its core strength lies in the proven Mitsubishi 4G64
engine, a four-cylinder powerplant providing dependable torque and reliability
for continuous use. The machine rolls on pneumatic tires, offering excellent
traction and shock absorption for uneven surfaces and outdoor terrain.
Operator control is facilitated through features like hydrostatic power steering
and a fully-welded, heavy-gauge frame for stability. The C25L is equipped with a
range of lifting systems including standard, Hilo, Triplex, and Quad
configurations, designed for productive operation across various applications.
This model is equipped with clear-view uprights available in Standard, Hilo,
Triplex, and Quad versions, featuring extra-wide masts, narrow center cylinders,
and optimized mast design for excellent visibility. It rolls on pneumatic tires,
offering excellent stability and traction for outdoor use. The distance from the
centre of the drive axle to the fork face is 17.9 in (455 mm). The wheelbase is
63.8 in (1,620 mm).
The total service weight of the truck is 8,390 lb (3,805 kg). When fully laden,
the axle load distribution places 12,350 lb (5,599 kg) on the front axle and
1,560 lb (706 kg) on the rear axle. In an unladen state, the front axle load
3,580 lb (1,625 kg), and the rear axle load 4,810 lb (2,180 kg). The overhead
guard height is 85.2 in (2,165 mm). The seat height is 44.8 in (1,139 mm). The
coupling height is 16.1 in (410 mm).
The Clark C25L is powered by the Mitsubishi 4G64 LPG
engine, a robust and reliable powerplant specifically designed for industrial
operation. It is a four-cylinder engine with overhead camshafts and a total
displacement of 143 cu in (2,350 cc).
This engine produces a rated power of 74 hp (55 kW) at 2,600 rpm. ECU-controlled
ignition timing provides increased torque. Lubrication is provided by a
pressure-fed system ensuring all moving components are adequately lubricated.
Cooling is managed by a liquid-cooled system designed to maintain optimal
operating temperatures. An electronic tachometer is standard equipment.
The drivetrain of the C25L is engineered for precise
control and long-term durability.
Transmission: It is fitted with a two-gear automatic transmission with gearbox
oil cooling. The transmission type is designated as W.
Travel Speed: The forklift achieves a laden travel speed of 13.3 mph (21.4 km/h)
and an unladen travel speed of 13.7 mph (22.0 km/h).
Axles: The drive axle is located at the front. The rear steer axle is robust
with proven steer axle design.
Brakes: The service brake system is hydraulic.
The electrical system is engineered to reliably support
the engine, safety features, and lighting. It operates on a standard 12-volt
architecture. The system powers the starter motor, engine control systems, and
all essential lighting components for safe operation. Increased safety is
provided through power failure protection to prevent uncontrolled lowering of
loads.
The chassis provides a rigid and durable foundation,
constructed from heavy-gauge steel with fully welded frame construction to
support all major components under load stress. Wheels and Tires: The C25L is
fitted with pneumatic tires. Available with dual tyres on the drive axle to
improve traction and stability.
Front: 7.00 x 12 - 14 PR
Rear: 6.00 x 9 - 10 PR
Track Width:
Front: 39.1 in (994 mm) standard, up to 42.3 in (1,074 mm) with dual tyres.
Rear: 35.6 in (904 mm)
Drive Configuration: The vehicle utilizes a 2-wheel drive configuration, with
the two front wheels serving as the driven wheels.
Steering: The steering system on the Clark C25L is a hydrostatic power steering
system that provides smooth and effortless control during low-speed maneuvering
and in confined spaces. The double acting steer cylinder ensures precise and
direct steering. A priority distributor in the hydraulic system ensures steering
priority in all conditions.
The hydraulic system is responsible for powering the
lifting, tilting, and any auxiliary functions. It utilizes a full-flow reverse
filter which filters the oil to the tank at each reverse flow. Rough particles
are filtered directly via a suction filter, thereby preventing them from
entering the oil circuit, ensuring a long service life for all hydraulic
components. A high-capacity pump provides adequate oil supply for the upright
and the hydrostatic steering. A large 12.4 gal (47 L) hydraulic oil tank allows
the use of numerous attachments. The system operating pressure for attachments
is up to 2,030 psi (140 bar). The hydraulic system capacity is 12.4 gal (47 L).
The main hydraulic pump has a rated flow of up to 9.2 gpm (35 L/min) for
attachments. Load handling is controlled via a load sensitive-response and
precise control valve. A safety valve provides extra safety and prevents an
uncontrolled lowering of the load at all times. The mast tilts forward by 8
degrees and backward by 10 degrees. Tilt cylinders are mounted in pendulum
bearings with an integrated tilt lock valve that prevents excessively rapid or
unintentional forward tilting of the lifting system.
The standard mast configuration is available as a
2-stage (Standard), Hilo, Triplex, or Quad upright design depending on
application requirements. Excellent visibility is provided by extra-wide masts,
narrow center cylinders, and optimized mast design. Angled mast rollers and a
robust 6-roller fork carriage with hook suspension ensure durability.
Mast Height (Lowered): 85.2 in (2,165 mm). Free Lift: 4.3 in (110 mm). This
feature allows for lifting loads at low heights without increasing the overall
mast height, a valuable function when entering trailers or working under
low-clearance structures. Maximum Fork Height: 130 in (3,300 mm). Mast Height
(Extended) (with LBR): 153.5 in (3,900 mm).
