A dual platform bed system has an associated machine for transferring material sheets from one platform bed to another. There are associated methods for both transferring and processing sheets on either or both platforms. Placing the platform beds adjacent one another reduces both human worker requirement and human and machine down time.

A blade drive shaft assembly (100) for a road saw comprising a shaft (120), a first mounting plate (125), a spacer removably fitted (126) on the shaft (120), a second mounting plate (127) removably fitted on the shaft (120), a mounting plate fixing adapted to secure the second mounting plate (127) to the shaft, a first circular saw blade mounted between the first mounting plate and the spacer (126), and a second circular saw blade mounted between the second mounting plate (127) and the spacer (126), wherein the first mounting plate (125) is integrally formed with the shaft (120) from a single piece of metal. A road saw incorporating the assembly is also described, as well as a method of forming, filling and compacting a trench and a method of making a blade drive shaft assembly.

A machine for milling pavement such as a rotary mixer or road planer includes a cutting rotor that is vertically adjustable with respect to the frame and that is accommodated in a rotor enclosure. The milling machine may be associated with a visual camera network having one or more cameras located about the milling machine with a field of view toward the rotor enclosure and work surface. An image augmentation system can generate a reference line augmentation to superimpose over one or more visual images obtained by the cameras and display the augmented images on a visual display.

A road milling machine includes a machine frame, at least three travelling devices, a milling drum, and at least one hydraulic drive system. The hydraulic drive system includes at least one hydraulic pump, at least one hydraulic fixed displacement motor for driving at least one driven travelling device, and one each hydraulic variable displacement motor for driving the remaining travelling devices. A first gearbox is arranged between the fixed displacement hydraulic motor and its associated travelling device. One each second gearbox is arranged between each of the hydraulic variable displacement motors and their associated travelling devices. The transmission ratio of the first gearbox is lower than the transmission ratios of the second gearboxes and/or the displacement volume of the fixed displacement motor is smaller than the maximum displacement volume of the variable displacement motors.

The invention relates to a quick-change holder for a quick-change chisel holder system for fastening a rotationally symmetrical milling chisel to a milling roller of a road milling machine, comprising a quick-change holder body, a chisel shank receptacle running along a longitudinal center axis in the quick-change holder body for receiving a chisel shank of the milling tool, a quick-change holder cone, which is formed by the quick-change holder body, lies in extension of the chisel shank receptacle, and for this purpose is designed to be clamped in an at least partially complementary holder receptacle of a basic holder of the quick-change chisel holder system, a tension means bearing arranged on the quick-change holder cone and designed to engage a tension means, with which the quick-change holder cone can be clamped on the basic holder in the direction of a cone axis of the quick-change holder cone, wherein the chisel shank receptacle and the tension means bearing are designed in such a way that the longitudinal center axis and the cone axis lie in a common plane and are angled relative to one another in this common plane. Furthermore, the invention relates to a quick-change chisel holder system and a milling roller.

Embodiments disclosed herein are directed to a system for removing road material. In an embodiment, the system may include a milling drum and at least one pick mounted on the milling drum. The pick may include polycrystalline diamond at least partially forming one or more working surfaces of the pick.

A milling system for a milling machine includes at least one cutting assembly configured to be coupled to a drum. Each of the cutting assemblies includes a base portion and an impact portion. The base portion includes a standoff coupled to the drum, a first base block coupled to the standoff, and a second base block coupled to the standoff at a position upstream of the first base block in a direction of rotation of the drum and at angle from the first base block. The impact portion includes a cutting bit and a tool holder coupled to the first base block, and a protective element coupled to the second base block.

The present invention relates to a chisel holder system comprising a milling chisel, a chisel holder and a clamping device, in particular a clamping screw. The present invention further relates to a milling drum and a ground milling machine having a chisel holder system.

The self-propelled construction machine according to the invention, in particular road-milling machine, recycler, stabiliser or surface miner, comprises a machine frame 2, which is supported by a chassis 1, which has wheels or tracks 1A, 1B. A milling drum 4 is arranged on the machine frame. The wheels or tracks 1A, 1B and the milling drum 4 are driven by a drive unit 8. Furthermore, the construction machine comprises a control unit 19 for controlling the drive unit 8 and a signal-receiving unit 18 for detecting at least one measurement variable M(t) which is characteristic of an operating state of the milling drum 4. The construction machine is characterised in that the rotational speed of the milling drum 4 is adapted, on the basis of at least one measurement variable M(t) which is characteristic of a critical operating state of the milling drum, to the operating conditions of the construction machine in such a way that the milling drum is operated in a non-critical operating state. The adaptive open-loop control of the milling drum rotational speed allows the construction machine to be operated at an optimum operating point with respect to the milling drum rotational speed.
