The housings including a groove configured to receive a bearing and a shaft extending at least partially through the base and housing. A tip device is also provided which includes a base, a rotatable support frame having: a first support configured to receive a pressure side of a wind turbine blade, a second support configured to receive a suction side of a wind turbine blade, and an opening, the opening configured to receive a portion of a wind turbine blade.

In some embodiments, a cutting system including a movable blade or a reciprocating blade operably coupled to a motor is disclosed, wherein the cutting system comprises a diverting feature. In some embodiments, a diverter proximity relative to the movable blade or reciprocating blade is selected to facilitate diversion of a material during cutting. In at least one embodiment, the movable blade may be movable blade for an oscillating tool. A cutting system according to the present invention may be coupled to a container, for example, a residential trash container or a residential recycling container.

A wind turbine blade handling apparatus for rotating and lifting a blade. The apparatus includes a root device having a root support member with a concave upper surface and rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; a base, and a scissor-lift mechanism with intersecting struts which converts from a lowered position wherein the struts are disposed in a generally coplanar configuration, to an elevated position wherein the struts are disposed in an angled configuration.

A wind turbine blade rotating and braking apparatus comprising: a root device including: a root support member having an upper surface with a radius of curvature and configured to receive a portion (e.g. root) of a wind turbine blade, rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; braking mount on the sides of the root support member; and a braking mechanism (e.g. strap or band) fixedly attached to the first mount, releasably attached to the second mount and extending above the blade to apply a braking force to the blade. Once applied, the braking force can be maintained by a locking pin.

A test bench for screwdrivers comprises a hydraulic brake unit (11) provided with a coupling (12) for a screwdriver to be tested and angle and torque measurement transducers (15). The brake unit (11) is supplied by a proportional electrovalve (16) under the control of a PID controller (19) which receives an electrovalve control signal (22) from a control unit (26) so as to follow braking curves depending on the angle of rotation and/or torque measured. The bench comprises a memory (21) for storing different sets of parameters for the PID controller (19), which can be selected by the control unit (26) so as to have different control characteristics. A method for controlling the bench is also described.

A support frame for a power tool includes a top configured to support a table top and a bottom arranged opposite and parallel to the top. The bottom is configured to support the support frame on a surface when the support frame is in a first position. The support frame further includes a side arranged between the top and the bottom and configured to support the support frame on the surface when the support frame is in a second position. When the support frame is in the first position and the second position, the table top is spaced apart from the surface.

A method for configuring an assembly workstation, the assembly workstation having container receptacle devices configured to receive an associated material container, each container receptacle device having a first data carrier, the material containers having a second data carrier, the assembly workstation having a first position determination device configured to ascertain one of (i) a position of a hand of a worker and (ii) a marking connectable to the hand, the first position determination device being connected to a control device, the method comprising: capturing a reference position corresponding to a reference point on a container receptacle device that is touched by the hand of the worker; reading out first data from the first data carrier associated with the reference point; reading out second data from the second data carrier associated with the reference point; and storing the reference position, the first data, and the second data.

A wireless charging system for power tools and other devices includes a charging module, docking frame, and tool holder. When a device is placed on a charging surface of the charging module, the charging module is configured to wirelessly charge the device. The charging module can be mounted within the docking frame or the tool holder via a mounting interface, and the tool holder can be affixed to a rigid surface. The docking frame can also be attached to a rigid surface, or can be mounted within the tool holder as an intermediate piece. The tool holder is configured to support the charging module such that the charging surface is at an angle. This configuration optimally locates the device relative to the charging module and allows the charging surface to act as a resting surface for the device between operations.

A modular work station includes a platform supporting a stem, a power tool coupled to the stem and supported for movement relative to the stem, and a table removably coupled to the platform. The table includes a first working surface and a second working surface opposite the first working surface. The table is further selectively coupled to the platform in a first orientation and a second orientation. The first working surface faces toward the power tool while the table is in the first orientation, and the second working surface faces toward the power tool while the table is in the second orientation.

A wind turbine blade suspension and rotation device capable of raising and lowering the blade includes a blade housing configured to receive a blade and having at least one guide on an exterior surface; a base; a first telescopic frame disposed on a first side of the base; a second telescopic frame disposed on a second side of the base; at least one adjustable strap, the adjustable strap disposed between the adjustable frames; wherein the at least one strap extends through the guide on the exterior surface of the housing to suspend the blade.
