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.
Deutz used bauma to show two hybrid projects it is currently working on, including a hybrid drive for excavators and an innovative start/stop system for compact wheeled loaders. The hybrid drive is based on using a 160kW Deutz TCD 6.1 L6 engine with an integrated motor-generator. The engine is linked to an on-board electrical power network that uses super capacitors, a power inverter and an electric slew motor, allowing components to harvest, store and use electrical energy, specifically for slewing functio
Sandvik claims that its 18.9tonne CH550 cone crusher offers customers good material shape and low operating costs in a range of material applications. A development of the company’s Hydrocone design, the CH550 can be configured for either secondary or tertiary crushing applications with a wide performance range.
ZF has chosen a pair of radial hydraulic motors for use in its compact single-speed hydrostatic transmission, the 2HC85, which has been developed for compact wheeled loaders up to 100kW and 10.5tonnes operating weight. For high-torque start-up, the transmission sends oil to both motors and demands maximum stroke to travel from 0-16kph, before isolating one motor and then using 100% oil flow through the remaining motor to propel the machine to its maximum travel speed of 42kph. ZF said radial motors afford a
