Description

With the introduction of the S line as a special element of the new EFG Series 5 electric fork lift trucks, Jungheinrich has expanded the ‘Pure Energy’ technology concept via the 48-V and 80-V motors into the 3.5 to 5.0 tonnes capacity classes. ‘Pure Energy’ enables a reduction of up to 20% in energy consumption (in comparison with the preceding model). Consequently, it is now possible for a truck in this class to complete two shifts with a single battery charge.
With the introduction of S line, two important customer requirements have been met:

1. The requirement for high residual capacities – particularly in connection with attachments and
2. the requirement to increasingly use emission-free trucks outdoors – as a replacement for trucks powered by internal combustion engines.

The ergonomics have also been designed with Jungheinrich’s typical focus on an operator-oriented workstation: A day’s work is made easier with controls which can be intuitively adjusted and many storage options.
The Series 5 is completed with the SnapFit lateral battery exchange system. SnapFit guarantees the reliable, simple and quick repla%ment of batteries.

Innovations

Pure Energy technology package

Pure Energy comprises three components. 4th generation 3-phase AC technology, compact electronics and compact hydraulics. The current 3-phase AC technology optimises the coordination of hardware and software, bringing them to a new, optimum level of efficiency. The result is maximum throughput with the lowest consumption and two-shift operation on one battery charge.

Parameter steering

With parameter steering, steering support is dependent on the travel program. At low speeds, support from the electrical steering is high – the operator needs to make fewer movements of the steering wheel. At higher speeds, the steering support diminishes. The advantages are: a) minimising unwanted steering movements, b) more legroom due to more compact design and c) further improvement in energy efficiency and throughput.

S line

With the introduction of 3-phase AC technology in electric counterbalanced trucks, these will increasingly be used outdoors and as an alternative to trucks with internal combustion engines, particularly in Europe. In addition, applications will become more specific and, consequently, attachments will be tailored more precisely to applications. The S line offers the necessary range of features needed by customers for difficult indoor and outdoor applications as well as costly attachments.

Market relevance

Energy saving of at least 20% compared with preceding model
In addition to maximum throughput for the lowest possible consumption (as per Andersom Testing comparison test), the aim was to achieve two-shift operation on one battery charge for the first time in the 3.5 to 5 tonnes class.

Adaptation to changing market/customer requirements
Another main aim of the development project was the adaptation of the series to changing market conditions. Due to a) the tightening up of emission regulations, b) customer requirements for lower carbon footprints and c) a more favourable Total Cost of Operations, electric counterbalanced trucks are being considered more frequently for applications where, until now, conventional diesel or LPG trucks would have been used. This demands flexibility regarding the attachments and truck characteristics which have been further optimised for outside use. All this has been achieved with the S series.

Lateral battery exchange with SnapFit
Quick battery access is the most frequently expressed customer requirement for battery handling on common pedestrian pallet trucks. The SnapFit battery exchange system, previously designed for EFG Series 2, 3 and 4, has now also been installed for Series 5.

Customer benefits

The main benefits for the user are improved cost-effectiveness, reliability and ergonomics.
The new EFG Series 5 offers improved energy efficiency and throughput. With two-shift operation now possible on one battery charge and the associated lower Total Cost of Operations, running costs are reduced and cost-effectiveness is increased.
With the SnapFit battery exchange, the excellent visibility and the wide variety of assistance systems the forklift truck is designed to provide a high level of safety.
Due to the infinitely and intuitively adjustable controls (armrest, steering wheel), the many storage options and a space-saving steering column, the EFG Series 5 enables the operator to work comfortably and without becoming fatigued.
