`
`extension or retraction of multiple telescoping assemblies is provided. The telescoping
`
`assemblies connect the main frame of a slipform paver to a side member of the
`
`slipform paver. Each telescoping assembly has a telescopic lock associated with the

`
`Abstract (English): A self-propelled construction machine includes a plurality of
`
`swing legs, each swing leg being supported from a ground surface by an associated
`
`crawler track steerably connected to an outer end of its associated swing leg. Pivotal
`
`Drawing
`
`movement of a swing leg may be accomplished by steering the associated crawler track through a non-zero steering angle until
`
`the lateral movement of the crawler track achieves the desired pivoting movement of the associated swing leg.
`
`DWPI Abstract
`
`Abstract-DWPI Novelty: The construction machine (10) comprises a machine frame (12) with a first swing leg (14A) and
`
`pivotally connected to the machine frame. The first and second ground engaging units include drive motors. A set of steering
`
`sensors detects steering angles of the ground engaging units relative to the swing legs. A first lock selectively locks and unlocks
`
`the first swing leg in pivotal position. A second lock selectively locks and unlocks the second swing leg in pivotal position. A
`
`controller includes a swing leg pivot mode.
`
`Abstract-DWPI Detailed Description: An INDEPENDENT CLAIM is included for a method for operating a self-propelled
`
`construction machine.
`
`Abstract-DWPI Activity: -
`
`Abstract-DWPI Mechanism: -
`
`Abstract-DWPI Use: Self-propelled construction machines, such as slipform paving machines.
`
`Abstract-DWPI-Advantage: The controller includes a swing leg pivot mode configured to allow each of the first and second swing
`
`legs to pivot relative to the machine frame in response to steering of the ground engaging unit connected to each swing leg
`
`while the machine moves in the direction of forward operation. The algorithm calculates the exact movement of the swing leg
`
`which will result from the steering of the track, and then actively facilitates the movement of the swing leg by that same
`
`amount, which ensures the compensation of the frictional forces in the swing leg assembly.

`
`Abstract (English): A scraper device for a milling drum mounted in a construction
`
`machine at a machine frame between lateral walls with a milling drum axis, with a
`
`two-part scraper blade arranged in a height-adjustable fashion behind the milling
`
`drum when seen in the direction of travel, the lower part of which can glide over the
`
`ground surface milled off by the milling drum, where the lower part of the scraper
`
`Drawing
`
`blade is adjustable in height when in operating position, it is provided that the upper part of the scraper blade is attached, at
`
`the upper end, to swivel about a swivelling axis parallel to the axis of the milling drum.
`
`DWPI Abstract
`
`Abstract-DWPI Novelty: The vehicle has a scraper blade (10) located behind a milling drum (6). The scraper blade has a lower
`
`portion (12) made to slide relative to an upper portion (14). A lifting actuator (22) is connected in between the upper and lower
`
`portions in order to make the lower portion slide relative to the upper portion. A swiveling actuator (30) is connected in
`
`between the upper portion and a portion fixed relative to the machine frame. The swiveling actuator is configured to pivot the
`
`scraper blade upward about a swiveling axis (18) parallel to the axis of the drum.

`
`Abstract-DWPI Mechanism: -
`
`Abstract-DWPI Use: Road milling vehicle for road construction work.
`
`Abstract-DWPI-Advantage: The swiveling of scraper blade is performed automatically without requiring any manual operation.
`
`The wear and tear of the scraper blade is reduced by reducing the pressure applied on the surface of scraper blade. The
`
`swiveling device is provided with an operating device which is arranged, in a space-saving state, at the upper end of the upper
`
`scraper blade. The operating device is arranged appropriately in order to obtain a large swiveling angle. A small swiveling radius
`
`is achieved because the lifting cylinders and the scraper blade are not required to provide any additional lifting path for an
`
`additional swiveling movement even after the completion of actual lifting movement. The design height of swiveling device is
`
`made low by arranging the operating device horizontally.

`
`Abstract (English): A method to determine a slip state of the compactor roller of
`
`a soil compactor caused by an oscillation motion of a compactor roller, comprising the
`
`steps:
`
`a) Preparation of an acceleration quantity related to the oscillation motion of the compactor roller
`
`b) Based on the acceleration quantity, preparation of an acceleration frequency spectrum,
`
`c) Based on the acceleration frequency spectrum, determining the slip state of the compactor roller.
`

`
`DWPI Abstract
`
`Abstract-DWPI Novelty: The method involves providing acceleration variables in connection with an oscillating movement (O) of
`
`a compressor roller (10) of a soil densifier based on acceleration of the roller in a direction parallel to a surface of a to-be-
`
`compacted subsoil (12). An acceleration frequency spectrum is provided based on the acceleration variables by using Fourier
`
`transform i.e. quick Fourier transform. A slippage state of the roller is determined based on the acceleration frequency
`
`spectrum. A slippage indicator representing the slippage state of the roller is measured.

`
`Abstract (English): A construction machine according to the disclosure comprises
`
`a primary drive configured to generate waste heat and one or a plurality of machine
`
`components, the machine components being arranged in the area of the primary
`
`drive of the construction machine. At least one of the machine components is
`
`Drawing
`
`arranged in a housing including at least one flow passage through which ambient air is sucked using underpressure or which can
`
`have ambient air supplied thereto using overpressure so that an air current is created.
`
`DWPI Abstract
`
`Abstract-DWPI Novelty: The machine (1) has a primary drive (2) configured to generate waste heat. Multiple machine
`
`components (4) are arranged in an area of the primary drive. A housing accommodates one of the machine components and
`
`includes a flow passage through which ambient air is sucked using underpressure or ambient air is supplied using overpressure
`
`such that air current is created. A fan generates pressure difference that creates the air current. The primary drive includes a
`
`cooling device for generating the pressure difference. The housing includes cooling fins that extend into the flow passage.
`
`Abstract-DWPI Detailed Description: The machine components are selected from a group consisting of electric or electronic
`
`components, hydraulic components, tanks and arbitrary components. The primary drive is an internal combustion engine.
`
`Abstract-DWPI Activity: -
`
`Abstract-DWPI Mechanism: -
`
`Abstract-DWPI Use: Construction machine e.g. road finisher and feeder (all claimed), for use in hot regions at a construction
`
`site.
`
`Abstract-DWPI-Advantage: The fan generates pressure difference that creates air current to be variably adjustable with respect
`
`to a flow rate according to a preferred variant, so that the machine is adapted to prevailing conditions manually through user
`
`inputs or automatically on the basis of parameters measured by sensors according to requirements, thus ensuring trouble-free
`
`operation of the construction machine even at high ambient temperatures. The machine ensures that air current flows across a
`
`largest possible area of an inner wall of the flow passage when an air inlet and an air outlet are arranged on opposite sides of
`
`the flow passage and/or of the housing, thus enhancing improved heat exchange, and achieving equivalent result through
`
`juxtaposed arrangement of the air inlet and the air outlet by extending a path along which air current flows between the air

`
`inlet and the air outlet using the flow passage. The flow passage is configured as the double-wall, so that waste heat of the
`
`primary drive does not arrive at the internal space of the housing when wall elements of the housing that face the primary drive
`
`are configured as double-walled elements, thus ensuing additional protection against overheating for the components in the
`
`housing and thermal loads from sides, and hence saving installation space if space available is restricted. The machine
`
`eliminates thermal bridges counteracting cooling effect from a machine frame or engine case when the housing is thermally
`
`decoupled at fastening units.
