A road milling machine includes a machine frame, front wheels or tracks, rear wheels or tracks, and a milling drum supported from the machine frame between the rear wheels or tracks. The front wheels or tracks are mounted on pivoting columns. Steering levers are attached to the pivoting columns. A steering tie rod includes a connecting part and a projecting arm. The connecting part is connected to the steering levers. A steering cylinder is connected to a free end of the projecting arm.

A milling machine includes a frame, a housing, a milling drum mounted on the frame within the housing and a drive assembly. A positioning assembly is provided for moving the drive assembly between a first position which is laterally outside the periphery of the machine housing and a second position which is laterally inside the periphery of the machine housing, and for locking the drive assembly in at least the first and second positions without requiring the operator to manually manipulate a locking pin.

The present invention relates to a method for positioning a milling drum box of a ground milling machine, in particular of a road milling machine, a recycler or a stabilizer, arranged on a machine frame relative to the ground, comprising the steps of: detecting the presence or absence of a ground contact, in particular in a region located in the front or a region located in the rear in the working direction (a), of at least one side plate of the milling drum box of the ground milling machine, and controlling a lifting and/or a lowering of the machine frame depending on the detected presence or absence of a ground contact. The present invention also relates to a ground milling machine for carrying out the method.

A milling machine can include a frame; a cutting rotor attached to the frame, the cutting rotor including a plurality of cutting bits positioned along a length of the cutting rotor; a plurality of temperature sensors positioned to determine a temperature proximate one or more of the plurality of cutting bits; a spray system coupled to the frame and including a spray bar having a plurality of nozzles configured to spray a cooling fluid on the cutting rotor; and a controller to receive the temperatures of the one or more cutting bits, the controller configured to determine whether more or less cooling fluid is needed for the cutting rotor based on the temperature proximate the one or more cutting bits.

A milling attachment is attachable to a host vehicle so that the host vehicle provides propulsion of the milling attachment. The milling attachment has a milling drum, a discharge baffle, and a baffle actuator. The milling drum is adjustably positioned vertically to determine milling depth. The discharge baffle is positioned rearward of the milling drum and pivotally adjustable to maintain a desired space between the milling drum and the discharge baffle at any of the vertical positions of the milling drum. The baffle actuator causes the pivoting of the discharge baffle. The milling attachment may further comprise a hood with a bit access hatch that provides access to the milling drum. The milling attachment may also further comprise a connection securing assembly for securing the milling attachment to the host vehicle by securing a bucket of the host vehicle within a bucket slot in the milling attachment.

A machine service set position control system is used on a machine that includes a frame, traction devices connected to the frame, a power source connected to the traction devices and configured to rotate the traction devices, a drum chamber connected to the frame, a milling drum rotatably supported within the drum chamber and configured to engage with a ground surface, and a rotor drive train connected to the milling drum and configured to rotate the milling drum to mill the ground surface, the rotor drive train including a gearbox. The service set position control system is programmed to determine a position of at least the rotor drive train and selectively operate a rotor drive train actuator connected to the rotor drive train based on the determined position to move the machine into a machine service set position allowing easy access for a technician to perform service.

In a self-propelled construction machine, in particular cold milling machine, recycler or surface miner, for working ground surfaces, comprising a milling drum supported at a machine frame and a conveying device arranged at the machine frame which accepts the milled-off material from the milling drum during the working operation and, on a continuously revolving first transport belt, unloads it, in conveying direction, onto a point of discharge at a discharge end along a parabolic trajectory, it is provided for the following features to be achieved: as a minimum, the last section of the conveying device as seen in conveying direction comprises no less than one continuously revolving cover belt arranged above the transport belt, said cover belt extending essentially parallel to the transport belt and resting against the milled-off material on the transport belt at least in a partial section of the length of the transport belt.

A ventilation system and method for a cold planer are provided. The ventilation system includes a settling box inside a water tank. The settling box includes a body. The body includes at least one sidewall defining an air inlet having a first cross-section to accept dust and fumes generated by a milling drum operation of the cold planer but to reject particles from the milling drum operation at or above a predetermined size. The settling box further includes an air outlet having a second cross-section less than the first cross-section of the air inlet. The ventilation system further includes an outlet pipe connected to the air outlet, a fan and a cleaning system. The fan is configured to pull air from below the air inlet into the settling box, through the air outlet and to the outlet pipe.

A cutting tool holding mechanism includes a base, a handle and a locking assembly. The base includes an abutting portion, a receiving groove, at least one limiting groove and at least one limiting hole. The limiting hole is disposed at the base and communicated with the limiting groove. The handle abutted against the base includes a sleeved portion and a plurality of positioning surfaces. The locking assembly includes a packing ring, a locking screw, a locking member and a guiding bolt. The locking member received inside the limiting groove includes a screwed hole and a guiding groove. The guiding groove disposed at one side of the locking member and is aligned with the limiting hole when the locking member is disposed inside the limiting groove. The guiding bolt is disposed in the limiting hole and is abutted against the guiding groove to inhibit the locking member from rotating.

A rock claw for attaching to a corner of a demolition hammer, the rock claw including a first wall having a first inner side surface, a second wall having a second inner side surface joined to the first inner side surface along a first intersection, and a third wall having a third inner side surface. The third inner side surface is joined to the first inner side surface along a second intersection and the third inner side surface is joined to the second inner side surface along a third intersection.
