STILL completely redesigns the bestselling electric forklift, the RX 20
FSDF member STILL completely redesigns the bestselling electric forklift, the RX 20, a powerhouse machine which electrifies operating companies and operators
With the launch of the distinctive silver-orange RX 20, STILL previously “hit the mark” with operating companies and operators of electric forklifts back in 2005. Over 80,000 units have been produced since this time, which speaks for itself. The Hamburg intralogistics specialist has now completely redesigned its bestseller, made significant improvements regarding compactness, ergonomics, performance and precision and has equipped it with smart assistance systems. Operating companies can not only look forward to a wider range of applications for this popular electric forklift, but also excellent handling performance with optimum efficiency. At the same time, operators can enjoy an unrivalled level of comfort.
“With the new RX 20 electric forklift family, we are setting a new standard in the market and are proving how the perfect interplay of all relevant truck characteristics can be used to achieve optimal handling performance and high availability. Today, we can already offer our customers the efficiency required to meet the challenges of tomorrow”, explains Thomas A. Fischer, Managing Director Sales, Marketing and Service (CSO) at STILL GmbH. “At the same time, we have paid attention to low operating costs in the selection of the components, thereby setting new standards in relation to the Total Cost of Ownership (TCO).”
The new RX 20 family consists of a total of 13 truck types, seven of which are 3-wheel trucks and six which are 4-wheel trucks and is designed for loads of 1.4 to 2 t with a load centre of gravity of 500 mm. The smart all-round trucks are ideally suited for combined indoor and outdoor use and quick and safe transportation of goods with a maximum driving speed of 20 km/h, even over longer distances. As a result, their performance can easily match that of trucks with combustion engines. The RX 20 also proves its capabilities when stacking pallets in high racks. For example, the RX 20-16L, lifts a load of 1.6 t with a maximum lift speed of 0.53 m/s to a height of up to 7,900 mm.
The efficient powerhouse was designed for a variety of applications and is the first choice wherever high handling performance and availability are key in tough 2 or 3-shift operations, such as in logistics, mechanical engineering, automotive, chemicals, rubber and plastics industries as well as in food retail. Due to its extremely compact design, it is of particular interest for applications where small working aisle widths are important due to narrow travel paths, such as beverage stores, building material stores, warehouse marshalling areas when loading and unloading lorries, containers and drive-in racks as well as block storage.
Here, the improvements can be found in the detail:
Power and performance are top priorities: The truck has a completely new drive module. Integrated in this are two encapsulated maintenance-free three-phase traction motors with active cooling, as well as a new generation of converters. This not only provides strong and reliable performance, but also maximum climbing capability on ramps. The front-wheel drive also provides the RX 20 with excellent traction. Depending on the rated capacity, the truck can drive on ramp slopes or inclined drives with a gradient of up to 20% at maximum load. As part of this, improvements have been made to acceleration, driving performance, lifting speeds as well as electric braking (reverse). The trucks are significantly more agile than their predecessors as a result.
To ensure that the truck always provides the performance demanded by the respective application, the customer can select between optimal energy efficiency or high handling performance at the press of a button. Speed, acceleration, as well as electric braking when changing drive direction can be adjusted in each driving programme.
High agility and compactness: The new RX 20 is considerably more compact. With this truck, STILL has implemented the requirement for a minimum working aisle width and clearance height together with a maximum size workplace. The extremely agile RX 20-14C and RX 20-16C are the perfect choice for customers who require particularly compact trucks with capacities of 1.4 or 1.6 tons. The agility of the trucks is based on an extra short truck frame which results in a small working aisle width while providing a large battery capacity (625Ah) at the same time.
A combination swing axle improves the working aisle widths for the 4-wheel trucks. Compared to their predecessors, the working aisle width of the 3-wheel trucks has been reduced by up to 29 mm and that of the 4-wheel trucks by up to 171 mm.
The new RX 20 trucks are already suitable for use in containers at their standard height of 2,035 mm. For use with particularly low gate clearances or in freight cars, the truck is also available with an overhead guard height of only 1,949 mm.
New battery concept ensures large range and availability: The 48-volt electric forklifts with standard chassis can now accommodate batteries with 625 Ah in circuit A- or B-, so the operating company can continue to use existing battery pools and exploit the advantages of the respective battery depending on the application profile. STILL has achieved this high level of battery variance due to its dual battery tray which is unique on the market.
The dual battery tray means that the customer is ideally equipped for the future, as new battery technologies such as Lithium-ion batteries can be used. This efficient technology is particularly suitable for extremely intensive applications which require maximum range.
With a Li-ion battery (49 kWh), the RX 20 has the largest range in its class. The customer can even swap between lead acid and Li-ion batteries as required. Like in predecessor models, a key success factor for the RX 20 is the quick and easy lateral battery exchange using a pallet truck. Journeys from and to the central charging station are no longer required. The time gained can be used for productive work.
An eye-catcher with a modern and streamlined design: STILL has placed a lot of emphasis on high-quality materials and a sturdy design. On the exterior, plastic parts have mainly been replaced by steel. As an example, the battery door has been reinforced and all headlights and safety lights are protected by robust steel sheets.
Perfect circumferential view reduces accidents: The mast has also been optimised by STILL, who have skilfully combined powerful lift with optimal visibility through the mast. Rigid and torsion-resistant mast profiles ensure safe and quick load handling, even with heavy loads with higher residual capacities. The RX 20 offers an outstanding view of the load, not only with the telescopic mast but in particular with the triplex mast. The new masts are characterised by a slender nested profile package as well as the use of C-profiles in the outside mast. The lift cylinders are positioned behind the profiles. This provides the driver with a clear view, both through the mast as well as past it on the sides.
The overhead guard was also designed for an optimum circumferential view. All overhead guards profile struts are narrower than the eye distance of the driver, so as not to obstruct their vision. The unimpeded upward view, facilitates quick and safe storage and removal even in high rack levels.
Increased ergonomics ensure fatigue-free and productive work: “The individual and user-friendly truck design including the driver’s workplace is extremely important, as this has a direct influence on the handling performance, occupational safety as well as the motivation and work performance of the driver”, remarks Fisher.
The workplace of the RX 20 offers the driver substantial freedom of movement. This already starts with the effortless access via the large step. The height of the foot-well is lowered by approximately 60 mm, and the driver’s workplace is lower by 50 mm. The cabin height in the interior has been increased by 16 mm and provides plenty of headroom even for tall drivers. A large handle, a non-skid rubber mat and a non-slip step edge increase safety when accessing and exiting the cab.
The foot-well is very generous and STILL has also paid attention to providing a lot of free space around the pedals, ensuring safe operation is possible even with large work safety boots. The pedals are low and arranged at almost the same height, to minimize footwork when operating the pedals. Service technicians are also pleased about the increased foot-well. For maintenance, they only have to loosen one metal sheet, which already gives them complete access to the parts to be serviced.
The RX 20 is also easy on the ears. STILL has made considerable improvements to the noise level of the trucks. In particular, it was possible to significantly reduce the noise of the lifting and steering pumps. A wide range of storage options complete the new driver’s workplace concept.
Precision increases safety and performance: STILL EASY Control, a newly developed display and control unit acts as a safety and communication centre. The fully graphical colour display with automatic brightness control is protected by a scratch-free surface. At a glance, the driver not only sees all truck parameters, such as driving speed, tilt angle, battery status, energy consumption etc but thanks to the menu-guided control and favourites buttons, they can also directly access driving and lift programmes, the battery remaining run time display and many other functions, even when wearing work gloves. A drive direction indicator on the display increases handling performance and safety.
Numerous assistance functions, including a display of the stability status on the screen, as well as a speed reduction when the fork carriage is raised not only improve safety but also contribute to precise load handling, which further increases the handling performance. Familiar assistant functions such as Curve Speed Control, which automatically adjusts the curve speed to the steering angle, are also used in the RX 20.
“Assistance systems will become increasingly important in future, to further increase the efficiency of truck operations”, explains Fisher. As a result, our engineers are always on the ball to develop additional smart solutions.”
