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.
Liebherr has developed a hybrid drive system for its HS8300HD heavy duty cycle crawler crane. The 350 tonne machine generates electrical power from its hydraulic free-fall winches, which offer up to 50 tonnes of line pull. Under this Pactronic system surplus energy is stored in a hydraulic accumulator and regenerated to assist the engine, reducing fuel consumption. This reuse of energy also cuts emissions from the machine.
According to Haulttoe, its new HT 23 RTJ platform offers a wider working envelope than previous designs in its size class. Platform working height is 22.5m, while its horizontal outreach is 18.3m, around 1m higher than competing units. A dual load system is available as an option, allowing a lifting capacity up to 450kg while the machine is said to offer a high lifting speed, taking just 56 seconds to reach full height and increasing its productivity in this product segment. It also offers high manoeuvrabi

The new 673 telescopic crawler crane from Sennebogen is said to be powerful, efficient and stable in operation. The machine offers a lifting capacity of 70tonnes crane while its telescoping boom is said to maximise versatility for an array of lifting applications. The new 673 R-HD is said to be rugged and durable and is the first telescopic crawler crane in the firm’s new E-series. Key features include stability and ease of transport, as well as fast set-up times. For on-road transport the crane is less tha
