Bonfiglioli is now offering a novel access platform drive system
5073 Bonfiglioli is now offering new electrical traction solutions for aerial platforms. These now offer electrical drive capabilities for telescopic boom, articulated boom, vertical and scissor type lifts. The firm says these drives are highly energy-efficient electric traction solutions for aerial platforms, which integrate motor and gearbox. This allows customers to benefit from electric traction technology as installation is easy and flexible due to compact component dimensions, while maintenance and repair needs are minimised and energy consumption is reduced along with emissions and noise. These last two factors are of particular importance to machines of this type, which often have to operate in environments where strict emission and noise limits may be in force. The new Bonfiglioli technology is designed for use with articulated and telescopic boom types, and vertical and scissor platform lifts with service heights from 5-27m. The drives are rugged and durable and can be used on models designed for site use on rough ground, or for indoor applications in tight spaces. The systems feature a two or three stage gearbox with an integrated mechanical clutch that offers reduction ratios of up to 1:95. The gearbox is coupled to a low voltage induction motor that has been specially developed for traction power and control applications. The low voltage, three phase induction motors are highly versatile and are available in voltages from 16-53V, and in various sizes for a wide range of power and size requirements. Features include an integrated temperature and speed monitoring system, an electronically controlled brake and the option of fitting a temperature sensor to suit specific needs. When integrated with a 24-80 V DC battery system and a low voltage control unit, the new technology ensures greater energy efficiency by controlling travel speed more effectively. The result is reduced energy wastage, better travel speed control, and increased gradability and traction. The same gearbox can be coupled to motors of different power ratings to meet design requirements and respect external shape and size restrictions, while various motor-gearbox coupling options are also available.
A new platform line has been launched by CTE, the B-Lift 390 High Range, a truck-mounted high range telescopic platform which is able to meet the requirements of various markets. The platform reaches 39 m of working height with 26.3m of maximum outreach and 450kg of maximum loading capacity. It has a telescopic boom (4 elements) with main boom and 3 telescopic extensions and H stabilisation system.
JCB will launch 427 and 437 wheeled loaders at Bauma, powered by Stage IIIB/Tier 4 Interim Cummins engines. First seen in prototype form at last year’s Intermat show, the two loaders are powered by the Cummins QSB6.7 engine, which offers a 9.4% increase in torque over the previous model. This drives through a lock-up converter and customers can choose a standard four-speed or optional five-speed transmission, which delivers a 16% drop in fuel consumption. In-cab noise levels have been reduced to just 68dB(A

Dana Rexroth Transmission Systems, the joint venture Dana and Bosch Rexroth, is to launch the R2 hydromechanical variable transmission (HVT). The modular transmission uses both a hydrostatic drive and a mechanical gearbox to deliver fuel savings of up to 25% compared to a torque converter transmission. Designed to work with engine outputs of 134-193kW (180-260hp), the R2 is suitable for use in wheeled loaders, motor graders, lift trucks and a variety of off-highway applications.
