Simulated bog-down system and method for power tools. One power tool according to an example embodiment includes a power source and a motor selectively coupled to the power source. The motor includes a rotor and stator windings. The power tool includes an actuator configured to generate a drive request signal and a power switching network configured to selectively couple the power source to the stator windings of the motor. The power tool includes an electronic processor coupled to the power source, the actuator, and the power switching network. The electronic processor is configured to detect a load on the power tool and compare the load to a threshold. The electronic processor is configured to determine that the load is greater than the threshold, and to control the power switching network to simulate bog-down in response to determining that the load is greater than the threshold.

A method for placing at least one duct/communication cable below a road surface in an area. The area comprises a first layer and a second layer, the first layer being a road layer, such as asphalt or concrete, and the second layer being a bearing layer for the first layer and being located below the first layer. The method comprising the steps of cutting a micro trench in the area through the first layer into the second layer, placing at least one duct/communication cable in the micro trench so that that duct/communication cable is placed below the first layer, and filling the micro trench so as to restore the road surface.

Disclosed is a machine for forming saw cuts into sidewalk concrete slabs, the machine comprising a frame, rubber tracks attached to the underside of the frame to self-propel the machine in a travel direction along a sidewalk during use, and a cutting assembly mounted to the frame. The cutting assembly comprises a saw for forming saw cuts, a linear actuator for moving the saw at a depth into the sidewalk, and a screw drive motor to move the saw to form the saw cut in a direction perpendicular to the travel direction. While road repair machinery has the luxury of more space, machines for sidewalks are smaller and tighter. The machine in accordance with the teachings of this invention uses a newly designed cutting assembly to keep the size of the machine useable for sawcuts in sidewalks.

A vibration suppressing handle arm (600) for an early entry concrete saw, the handle comprising a joint separating the handle into a first elongated part (120) and a second elongated part (140), wherein the first and second elongated parts are arranged pivotable with respect to each other about the joint, wherein the first part (120) has an elongation direction configured to align with an elongation direction of the second part (140) to form an elongation direction of the handle when the handle is in an unfolded position, the handle further comprising a resilient element arranged to resist but not prevent pivoting by the first elongated part (120) and the second elongated part (140) about the joint.

The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement for making a trench in the ground, a consolidation and laying means being arranged behind the blade arrangement, for clearing and safe-guarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. A blade assembly comprising compartments for cooling fluid and air.

A carriage (50) for a wall saw that includes a saw head and a motor-driven feed unit with a guide slide and a feed motor. The carriage is made up of a base frame (51) with a supporting frame (55) and a receiving plate (56), a guide frame (52) with a handle (58), and a chassis (53) with a first axle (64), a second axle (66), and at least three wheels (65, 67). At least one wheel (65) of the chassis (53) is designed to be connectable to a gearwheel (45) of the guide slide (26) in a force- and torque-transmitting manner with the aid of a connection device.

The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement (2) for making a trench (5) in the ground, a consolidation and laying means (3) being arranged behind the blade arrangement (2), for clearing and safeguarding the trench (5) from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. A blade assembly comprising compartments for cooling fluid.

A portable tile cutter includes a main unit having a base frame and a guard connected to the base frame, a cutter blade pivotally mounted at the guard, a driving unit connected to the guard and operable to rotate the cutter blade, a first handle connected to the driving unit, and a second handle connected to the guard and providing a grip. The component parts of the portable tile cutter are so arranged that moving one or both the driving unit and the second handle can achieve adjustment of the gap between the first handle and the grip of the second handle. Thus, the portable tile cutter can fit different users having different body sizes.

The proposal is for a separating blade for the material-removing machining of a mineral-containing hard material, wherein the separating blade is designed to be set in rotation by means of a drivable flange arrangement, and wherein a liquid coolant can be supplied to the separating blade for a machining mode. According to the invention, in an inner volume of the separating blade that is surrounded by parts of the separating blade, an inner structure for providing a flow path, through which the coolant can flow, between an inlet point and an outlet point is formed in such a way that, in the connected state with the flange arrangement, an outflow of portions of the supplied coolant from the inner volume is prevented along the flow path during the machining mode of the separating blade, thus ensuring that no coolant reaches the machining section on the outside of the separating blade.

A method for controlling a wall system when creating a separating cut in a workpiece between a first and a second end point is disclosed. The wall saw system includes a wall saw having a saw head, a pivotable saw arm, a saw blade and a blade guard. The separating cut is carried out in a plurality of main cuts. The pivoting movement of the saw arm in a main cutting angle is carried out in at least two steps with at least one intermediate angle, where a free cut of the saw blade is carried out in the respective intermediate angle between the pivoting movements of the saw arm.
