Sturdy material handlers for demanding materials handling tasks

SENNEBOGEN material handlers are designed for manifold applications and available with modular undercarriage solutions (mobile, crawler, stationary, rail and optionally heightened with pylon). With equipment lengths up to 40 m, numerous attachments and quick-coupling systems the machines are extremely versatile. All types are optionally available with either diesel engine or electrohydraulic drive.

In the different variants with I. C.-engine a KTR coupling type BoWex FLE-PAC combines an engine with a hydraulic pump. The torsionally rigid curved-tooth flange coupling has to meet a number of requirements – its primary task is to transmit the power reliably to allow the material handlers to perform the pending operations as requested. The coupling hub is made of steel, the flange toothing of carbon fibre reinforced nylon. This material combination provides the coupling with high dimensional stability even with temperatures up to 130 °C allowing for a long and maintenance-free permanent operation thanks to optimized coefficient of friction in the tooth combination. Due to its high torsion spring stiffness the coupling in addition makes sure that critical resonances are not generated, thus considerably contributing to the protection of the adjacent components and the overall power pack.

Mining vehicles for special operations


The machine plant Hermann Paus Maschinenfabrik develops special purpose vehicles for mining and tunnel construction. The product range comprises service and lifting platform vehicles, loaders, dumpers, shearing scalers and track maintenance vehicles.

The universal vehicles type MinCa are used for passenger and materials transport as well as for special operations and are able to take load capacities up to 3.0 t. The variable transport concept of this series provides for a basic vehicle the base platform of which different setups such as dynamite transport vehicles, water tank, fire engine, loading crane and platform or a service unit can be mounted on.

The I. C.-engine and variable displacement pump for the hydrostatic drive of the setup are connected by a KTR coupling. The connection is primarily responsible for reliable power transmission. Depending on the setup and requirements, either a torsionally rigid flange coupling type BoWex FLE-PA or a highly flexible flange coupling type BoWex-ELASTIC is installed here.

If the mining vehicles are used for stationary applications with a poor content of fresh air, the drive switches to electric mode. A torsionally flexible jaw coupling type ROTEX combined with a bellhousing features the connection between electric motor and hydraulic pump.

The cooling of charge air, cooling water and hydraulics is performed by a cooling system of the MMC series by KTR. The multiple circuit cooler is specifically selected for the vehicles of the MinCa series and approved for ambient temperatures up to 45 °C.

Wheel loaders for manifold applications


The eye-catching weycor wheel loaders by Atlas Weyhausen are used in construction industry, agriculture, garden and landscaping, materials handling or recycling. Currently the portfolio includes 16 different types of wheel loaders with standard shovel capacities from 0.32 m³ to 2.5 m³ and an engine power from 33,5 HP (24.6 kW) to 218 HP (160 kW). Having a service weight of 7,000 kg and a shovel capacity up to 1.5 m3, type AR530 is one of the medium size types in the portfolio. The wheel loader is equipped with a water-cooled 4-cylinder DEUTZ engine series TCD 3.6 L4 High Torque with 3.6 litres capacity and a maximum power of 55 kW.

KTR was charged with selecting the cooling system. A triple-circuit combined cooler type MMC is used for cooling charge air, cooling water and hydraulics. Another KTR component is mounted on the flywheel side. Here a BoWex flange coupling type FLE-PAC connects the flywheel to the hydraulic pump. The curved-tooth gear coupling serves for compensating for the displacement in the drive train. Subject to its high torsion spring stiffness it prevents critical resonances in addition, thus significantly contributing to protecting the adjacent components and the overall power pack.

Between nostalgia and environmental protection

The redesigned “New Bus for London” started service in February 2012. In line with the city’s goals of boosting London’s green image as well as noticeably reducing emissions, the most striking feature of the new buses was the new diesel hybrid motor retrofitted with the Vantage Power’s B320 Hybrid Retrofit system.

Subsequently, Vantage Power’s retrofit systems aim at fuel savings of up to 40 percent by way of state-of-the-art lithium ion battery packs and advanced control system technologies.

The system’s powertrain uses a KTR BoWex 80 HE mounted between the combustion engine and electric generator. The flange coupling is designed to produce 136 kW engine output and a torque of up to 700 Nm. Its task is to dampen non-uniform circulation arising from the engine and to transmit the torque efficiently. The retrofit system generates power for the electric drive and conforms with Euro V and VI standards, produces less noise and vibration while promising a purely electric cruising range of four kilometres.
