A device for raising a temporary wall to enclose an area includes a main body, a drive wheel attached centrally to the main body, a motor mounted on the main body and configured to drive the drive wheel, and a hook portion attached each end of the main body. Each hook portion has an arm member extending from the main body, a wheel support member extending from the arm member, the wheel support member extending substantially parallel to the main body, a wheel attached to the wheel support member on a surface facing the main body, and a depth adjustment mechanism configured to adjust a depth of the device by adjusting a length of the arm member. The device also includes a width adjustment mechanism configured to adjust a width of a gap between the wheel support members and a loop member attached to the main body.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

In a lifting and transporting device for lifting a load (13) and for transporting the same transversely to the lifting direction (8), for use in the production of a screwed flange connection (35), in order to bring a tensioning tool (13) into a tensioning position in which it is in engagement with a screw bolt connection (18) to be pretensioned, or into a transport position in which it is out of engagement with a screw bolt connection and can be transported to the next screw bolt connection, wherein the flange (36a, 36b) extends horizontally, comprising a frame (2) for picking up and for lifting a load (13), a holding device (3) for holding the load, wherein the holding device is movable relative to the frame in the lifting direction (8), and comprising a hoisting device (4) for lifting and lowering the holding device (3) with the load (13) attached thereto, wherein the frame (2) is mounted on a first and a second support bearing (5, 6) and the first support bearing (5) is designed for abutment against the flange upper side (14), the frame (2) is designed to extend from the flange upper side (14) along the flange face (15) to below the flange underside (16), the second support bearing (6) is designed for abutment against the flange upper side (14) or against the flange face (15), the holding device (3) is equipped to hold the tensioning tool (13) below the flange underside (16) with the engaging means directed upwards, and the hoisting device (4) is equipped to lift the holding device (3) with the tensioning tool (13) attached thereto from a lowered transport position into a tensioning position.

A stand-alone multipurpose lifting device includes an elongated vertical support section having a planar base section with an upper end including a substantially U-shaped receiving bearing including a plurality of pivot slots on either side of the U-shaped bearing and an angled elongated lever arm section. The lever arm section includes an angle strengthening gusset and a detachable extension arm and handle including a receiving sleeve for fitting over and receiving the end of the lever arm section. A device for cracking a seal formed around a manhole cover includes a horizontal cross bar section including a bottle jack holder recess, a bottle jack retaining means, two opposed leg sections, support struts between the horizontal cross bar and leg sections and a jack cap section including two lifting eyes including a hook and lifting chains for attaching to a manhole lifting arm detachably connected to a manhole cover.

A refuse bin includes a liner sealed to a container. An inflatable space is between the liner and the container, and an inlet to the inflatable space conducts a flow to inflate the inflatable space from a deflated state to an inflated state. In the deflated state, the liner lines a cavity for refuse in the container. In the inflated state, the liner extends above the open end of the container. The flow into the inlet pushes the inflatable space toward the inflated state causing the liner to lift the refuse. The refuse bin may further include a lid-lifting mechanism activation by inflation of the inflatable space or an insert that helps shape the liner in the inflated state.

A device for removing polycrystalline silicon rod pairs from a Siemens reactor has a body dimensioned to fit over a single rod pair. Once the rod pair is within the body, the body and enclosed rod pair is removed.

A device for use with one or more lines that includes a unitary rigid body having an annular portion surrounding a central opening and at least four finger sections that extend from the annular portion of the rigid body. A first finger section and a second finger section curve toward each other on one end of the rigid body and terminate in blunt tips that are spaced apart from each other by a gap. Similarly, a third finger section and a fourth finger section curve toward each other on an opposite end of the rigid body and terminate in blunt tips that are spaced apart from each other by a gap. The device maximizes the pulling strength of lines while reducing the possibility of line failure. Also disclosed are methods of using the device for shortening a line, belaying an object, joining two lines together and for forming a V-bridle.
