Counter Balanced Truck








Crown’s new, innovative C-5 gas-powered counterbalance truck can lift up to three tonnes and is designed to meet customers’ high expectations in terms of productivity, power and control, while addressing the two main challenges facing customers:
1. Lowering total costs of ownership:
In this product segment, the main challenge is to cut costs by reducing maintenance and increasing uptime – achieved in the C-5 by its extremely robust, reliable and energy-efficient Crown-built LPG engine and rugged powertrain. The highly durable full-circle power brake eases disc replacement and reduces the build-up of dirt, dual-radiator cooling combines precise ventilation with radiator cleaning to prevent overheating from build-up of debris, all of which significantly reduce maintenance costs. The On-Demand CoolingTM option includes a 5-year/10,000-hour extended warranty on the powertrain.
2. Operator confidence and comfort:
Contented operators get more done. Comfort, confidence and safety were Crown’s primary considerations when developing the C-5, focusing on increased satisfaction and productivity. The highly innovative hard cabin sets a new standard with its automotive comfort, perfect ergonomics and unprecedented all-round visibility.
1. Engine & Brakes:
The Crown-built 2.4-litre industrial engine and rugged powertrain offer an unprecedented lifespan and longer service intervals. Internal balancing shafts and rubber mounts virtually eliminate engine vibration. The gear-driven valve train avoids costly belt replacements or chain adjustments. The fully enclosed circle power brake eases disk replacement and reduces build-up of debris. The standard hill-hold function prevents the truck from rolling down inclines without constant pressure on the brake pedal.
2. Cooling:
The dual-radiator cooling system improves heat management by providing separate cooling for engine and transmission. Crown’s unique On-Demand CoolingTM (ODC) option combines precise ventilation with radiator clearing. With each engine start, the fan automatically reverses to remove debris from the radiator.
3. Hard Cabin:
The fully enclosed cabin with clear-view doors, two-way sliding windows, front and rear wipers and heater offers car-standard driving comfort in all weather conditions. The exceptionally large windows and curved front windshield allow unparalleled 360-degree vision and unobstructed upward view. ISO-mounts virtually eliminate cabin vibrations. The heater is integrated in the right-hand door making the truck easily accessible from both sides.
4. Control:
Crown’s proven Intrinsic Stability System™ continuously monitors the degree of tilt and fork height, automatically adjusting truck functionality as required.
Pushing lift trucks and their engines to the limit is a fact of life in modern operations but can lead to lost productivity or costly damage. Research showed that customers demanded a better IC truck with the power, control and reliability to perform under the toughest conditions, year after year. Crown spent thousands of hours researching and understanding customer needs, testing trucks in demanding indoor and outdoor applications to overcome the most persistent problems that typically plague gas trucks:
The C-5 creates a new benchmark in its segment. To create a game-changing gas-powered lift truck, Crown combined reliable engine, braking and cooling technologies into a robust and durable truck, resulting in increased uptime and less maintenance and repair costs.
Operator satisfaction is a key factor for Crown when developing innovative truck solutions. To provide an optimum operator workspace and car-standard driving comfort, Crown developed the highly innovative hard cabin which truly sets new industry standards.
Furthermore, Crown also applied decades of expertise with counterbalanced trucks to ensure static and dynamic stability with the C-5. The Crown Intrinsic Stability System combines engineering, manufacturing and integrated technology to proactively ensure optimal safety and performance.
Customers benefit from the Crown C-5 in terms of productivity, durability, reliability, stability, operator confidence and safety. They get an extremely robust and powerful truck with an exceptionally long life-span – even in the toughest applications. Less maintenance, dependable uptime and the truck’s versatility add up to lower cost of ownership.
Customers’ feedbacks confirm the valuable benefits of the C-5: Joel Back from Gold Metal Recycling in Texas states: “The worst thing about our environment is the amount of dust and debris in the air. With our other forklifts, operators were manually clearing the radiators at least once a day. I lose $1,000 a minute when the forklifts processing the bailers are sitting in the maintenance bay. My maintenance costs for the C-5s are comparably lower than my other forklifts. I haven’t had any over-heating issues or axle or brake problems. The same can’t be said for the other forklifts in my fleet.”
Kevin Cooper from Terex Trucks Motherwell adds: “The C-5 is very powerful with enough torque to easily deal with inclines, even when carrying heavy components. Our drivers in particular love the C-5. The cabin is spacious, easy to access and well built, while the suspension seat ensures a very smooth and comfortable ride. Driver feedback tells us the truck is very stable, remaining smooth and controlled even on rough ground.”

The C-5 is Crown’s first combustion-engine machine on the European market. The new four-wheel forklift with LPG engine is available with load capacities up to three tonnes and is equipped with an industrial, energy-efficient 2.4-litre engine with very low vibration levels.
At first glance, the C-5 looks like a true Crown: idiosyncratic, robust and accessible. Years ago, the brand was the first one with an extremely curved cabin columns offering the driver maximum space – both optically and in practice – when entering and exiting. The additional step is spacious and fitted with good anti-slip matting complete with a dirt wiper on the edge. The test team think the step could be slightly lower. Foot space is genuinely huge, completely free of obstacles and equipped with a perfectly fitted thick rubber mat. Acceleration and braking pedals are well arranged and positioned. The brake is extremely wide and offers a combination of braking and inching for precision manoeuvring. This feature is designed to ensure a smoother transition between driving and inching, which is still quite abrupt. Separate pedals for braking and inching are available at no surcharge.
The optional “Seatbelt-interlock” on the C-5 means the operator can no longer simply climb on board and drive off without belting up. This makes Crown a leader in terms of compliance with the regulations, as this feature will be compulsory for all forklifts two years from now. Driving and working with the C-5 is stress-free. The machine responds directly and operating characteristics are intuitive. The hydraulic levers are arranged on the dash and permit simultaneous operation. Thanks to their position and shape – and the fact that the heater is integrated in the right-hand cabin door – the driver can also enter and exit the truck from the right.
Thanks to the intelligently rounded contours of the dash and the slimline steering column, the cabin makes an extremely spacious impression. The seat is well-formed and comfortable. The steering column tilt is steplessly adjustable. A height adjustment feature would further enhance user-friendliness. The low counterweight, the high seat, the forward position of the driver, the angled cross-struts and the open mast design ensure an excellent view. This is even the case with forklifts with fully closed cabin, like the one in the IFOY test. With its transparent doors, sliding windows on both sides that can be opened to both the front and the rear, screen wipers at front and back, and heating system, the cabin offers car-like comfort levels even in extreme weather conditions.
The proprietary Crown engine technology in the C-5 is special. It uses robust materials for a long service life and low costs. Instead of lightweight aluminium parts, the engine is made of cast iron and steel; a maintenance-free transmission replaces timing belts and chains. Two balancing axles and a specially cushioned suspension system render the engine virtually vibration-free. In a demonstration using a full glass of water on the top of the engine, the C-5 moves from a standing start to full speed without spilling a single drop. Crown has developed the “Power Brake” for its braking system. This inhibits the full circular area of the brake discs, thereby preventing dust and wear. Crown offers a 10,000-hour or five-year warranty on engine and powertrain, provided that the forklift is equipped with On-Demand Cooling (ODC).
When put through its paces on the IFOY test circuit, the C-5 showed itself to be a powerful and smooth machine. Although the inching feature takes some getting used to, the test scores were stable. Productivity is slightly better than average for this class, while energy consumption is slightly higher. It makes little difference whether the truck is operated in “Economy” or “Productivity” mode, and even the limitation from 20 to 15 km/h hardly makes a difference. The truck is even more energy-efficient in “Fast” mode if it uses roll-out without having to step on the gas. In the view of the test team, the sound proofing could be better at full speed.
All in all, the first encounter with the Crown’s new “trump” is a positive one. The forklift is spacious, easy to operate and comfortable. The machine has above-average power and meets the high expectations. There is room for improvement as regards the inching pedal and engine noise at full speed; a height-adjustable steering column would be ideal.

Counterbalanced trucks with a load capacity of 3 t are a popular choice among customers, and this is a segment in which gas-powered machines are well represented. Consequently, the developed innovations are of significance for a large customer base. At the same time, Crown appears to have designed its new C-5 specifically for very heavy-duty tasks. Quote: “an extremely robust and powerful truck with an exceptionally long life-span”, “bigger axle and bearing diameter”. The outcome of these development goals is a truck with a far higher weight than comparable forklifts in the segment. However, the higher weight basically also means higher energy consumption and hence higher CO2 emissions in daily operation. In times of increasing environmental awareness, this tends to limit the number of potential customers.
The innovative character of the Crown C-5 is not due to the novelty of a single key component but the result of multiple individual improvements that need to be considered separately.
With regard to the full-circle disc brakes, the customer benefit is said to be extended maintenance intervals. This only applies in comparison with conventional drum brakes, however. A whole range of counterbalanced trucks are already fitted with maintenance-free multi-disc brakes.
The engine boasts a number of extremely high-quality components such as the balance shafts and an additional oil cooler. The advantages for the customer include a smooth-running engine, reduced maintenance requirements and long service life.
The cooling system appears to be extremely sophisticated. Whether this added effort pays dividends for all customers is open to question. At the same time, however, the reverse-action fan has the advantage that it automatically cleans the radiator during operation when the truck is used in highly soiled environments.
The full cabin listed in the entry for the award has big windows and features intelligent details, such as the grip with horn button for reversing. The “Intrinsic Stability System” is a proven – and hence not a new – feature.
Full-circle disc brakes are a well-known brake type and have also long been used in industrial trucks (e.g. lift trucks). This type of brake generally works in the same way as a single-disc clutch of the kind used in cars.
The engine components are of high quality but have long been used in vehicle engines.
The so-called on-demand cooling system is also state of the art for automotive engines. What is new in forklift trucks, however, is the reverse action of the fan to clear debris from the radiator.
The way the technical innovations have been implemented makes an intelligent and solid impression.
