A clamp for use with a cutting machine, the clamp comprising: a clamp frame; a low profile clamp head operatively connected to the clamp frame, wherein the clamp head has a clamping surface for pressing on a work surface of a work piece to hold said work piece; and a fixing element, operatively connectable to the clamp frame, for providing a clamping force to the clamp head by fixing the clamp to a support base for the work piece. In embodiments, the clamp head may have a low profile clamp head, made of plastic to prevent damage to a cutting bit.

A collar flange assembly clamping tool is disclosed, including an axle having a long axis, and a pair of arms mounted on the axle. At least one of the arms is slideable along the long axis. Each arm includes a primary axis perpendicular to the long axis of the axle, a proximal end portion, and a distal end portion with a tab. The proximal end portion includes a clamping device that moves in a direction perpendicular to the primary axis of the arm and the long axis of the axle.

A clamping unit (1) for clamping a workpiece, with an electric drive, and a gearbox unit having an arrangement of rolling elements (9). The gearbox unit is used to convert a rotary motion of an actuating element into a translational motion. By means of translational motions of the actuating element, clamping elements (5) can be moved into a clamping position in which a workpiece is clamped with clamping elements (5), and into a release position in which clamping elements (5) release the workpiece.

A removing apparatus includes a main body, an operation member, and two connection members. The main body has a main arm, and a first and second side arms on two ends, so as to form a C shape, with a combination bore on one end of one side arm away from the main arm. The operation member is on another side arm and axially movable, with another combination bore on one end of the operation member. Each connection member has a base portion, with an insertion portion extending from the one lateral side of the base portion to be combined with the combination bore. Each connection member has a large and a small column portions connected in a stage shape to form a stage face. Sleeves of different sizes can be combined with the lateral side or the stage face of the connection member for removing objects.

Systems for cutting cylindrical workpieces such as pipe are described. The systems include a clamping assembly and can be used in various methods. In one method, the clamping assembly and a cutting tool or saw is used on a rotating workpiece. In another method, the clamping assembly and a cutting tool or saw is used on a stationary workpiece. Also described are frames that can be secured to the clamping assembly.

A carrying device is provided. The carrying device includes a stand, an upper clamp connected to the stand, a lower clamp assembled to the stand, a manipulation mechanism assembled to the stand and interlinked with the lower clamp, and a supporting column assembled to the lower clamp. The manipulation mechanism can drive the lower clamp to move relative to the upper clamp, and the upper clamp and the lower clamp jointly define a receiving space therebetween. The supporting column is movable relative to the lower clamp, so that the carrying device can be adjusted in a first clamping mode or a second clamping mode. When the carrying device is in the first clamping mode, the supporting column is located in the receiving space and faces toward the upper clamp, so that the supporting column and the upper clamp can jointly clamp a plate part of a first structure.

Systems and methods for a dual sided clamp. More specifically, a clamp with a channel configured to receive a level on a first side of the clamp, and a triangular shaped cutout configured to receive a shaft associated with different sized valves on a second side of the clamp.

A corrugated band clamp is configured to effectively secure a sleeve around a pipe. The corrugated band clamp comprises an elongate member having a first lateral side and an opposing second lateral side. Typically, at least a portion of the length of the elongate member comprises a corrugated portion and at least a portion of the length of the elongate member comprises a non-corrugated portion. The corrugated portion of the elongate member enables the corrugated band clamp to effectively secure sleeves on pipes with non-parallel surfaces. In addition, applications of the corrugated band clamp system, methods of manufacture and methods of use are provided.
