Soil compactor

A soil compactor includes at least one compactor roller supported on a machine chassis to be rotatable about a roller axis of rotation. The at least one compactor roller is supported in its two axial end areas respectively via a suspension assembly on the machine chassis to be movable with respect to the same. ... Hamm Ag

Earth working roller

. . An earth working roller for use in an earth working machine comprising a roller drum (30), which extends in a direction along a roller axis of rotation (d), surrounds a roller interior (34), and has an essentially circular outer circumferential contour, wherein a substrate breaking configuration (38) is provided on the outer circumferential surface (32) of the roller drum (30), characterized in that the substrate breaking configuration (38) comprises a plurality of impact bars (40) along the roller drum (30) essentially in the direction of the roller drum axis of rotation (d), as well as a plurality of breaker bars (44) along the roller drum (30) in an essentially circumferential direction.. . ... Hamm Ag

Construction machine

A construction machine includes a system area rotatable about an axis of rotation with respect to a machine frame. On the rotatable system area is at least one sensor, a data transmission unit with at least one transmission antenna, and a first data transmission arrangement for transmitting data from the at least one sensor to the data transmission unit. ... Hamm Ag

Soil compactor

. . Soil compactor including a compaction drum rotatably supported by a compaction roller frame, wherein the compaction drum frame comprises two longitudinal members arranged in a direction longitudinal to the compactor on both sides of the compaction roller and supporting said compaction roller, and, connecting the two longitudinal members together, two cross members arranged in a direction perpendicular to the compactor and along both sides of the compaction roller, wherein the compaction roller frame is connected to a compactor main frame via one of the two cross members, and wherein at least one sight opening is provided within the other of the two cross members.. . ... Hamm Ag

Soil compactor and method for compacting substrates

A soil compactor comprises at least one compacting roller (18, 22) rotatable about an axis of rotation, a temperature detecting device (42) for providing temperature information representing a temperature of a substrate (u1, u2, u3) in the area of the soil compactor (10), a sprinkling device (24, 28) assigned to at least one compacting roller (18, 22) for sprinkling this compacting roller (18, 22) with fluid, and a control device (40) for controlling at least one sprinkling device (24, 28) and/or for generating a sprinkling indicator on the basis of the temperature information.. . ... Hamm Ag

Method for determining the compaction state of substrate

A method for determining the compaction state of a subgrade to be compacted using a roller compactor comprising at least one compactor drum having an oscillation-inducing arrangement and rotatable about a drum axis of rotation comprising the following steps: during at least one period of oscillating movement of the compactor drum, repeatedly determining the acceleration of the compactor drum in an first direction, representing a first acceleration value; in association with each first acceleration value, determining an acceleration of the compactor drum in a second direction representing a second acceleration value in order to provide acceleration value pairs, each consisting of a first acceleration value and a second associated acceleration value; and for at least one oscillation period, defining a compaction state value representing the compaction state of the subgrade based upon the period of oscillation determined for said acceleration value pairs.. . ... Hamm Ag

Device for detecting the motion of a compactor roller

A device for detecting the motion of a rotatable compactor roller about a compactor roller axis of rotation includes at least one motion sensor and an energy supply for the at least one motion sensor. The energy supply includes a generator having a stator and a rotor rotatable about a rotor axis of rotation with respect to the stator.. ... Hamm Ag

Soil compactor

A soil compactor, including at least one compactor roller, which is free to rotate about an axis of rotation of the roller, with a plurality of roller segments, which follow one another along the direction of the axis of rotation of the roller, wherein, in each case, at least one electromotive drive for producing an oscillating torque is assigned to each roller segment.. . ... Hamm Ag

Seat for a construction machine, and construction machine

In a seat for a construction machine, comprising a seat console, a device for lateral displacement of the seat in a transverse direction relative to the direction of travel of the construction machine, and a seat rotating device, it is provided that a stop limiter device is operative to limit the maximum allowable rotational angle of the seat in a variable manner, each time in dependence on the set position of the lateral displacement of the seat.. . ...
