There is provided a magnetic clamping device (10) for magnetically clamping to a magnetically attracted material (30). The device comprises at least one permanent clamping magnet (14, 44) for magnetically clamping to the magnetically attracted material wherein the magnet is movable relative to the magnetically attracted material from a position remote from the magnetically attracted material to a clamping position for the clamping of the material by the magnet. The device also includes damping means (22, 24) for damping the movement of the clamping magnet to the clamping position. The damping means biases the clamping magnet away from the magnetically attracted material to assist release of the clamping magnet from the magnetically attracted material. In addition, the device has support means (16, 40, 58) to which the clamping magnet is mounted for the relative movement of the clamping magnet from the remote position to the clamping position and for withdrawing the clamping magnet relative to the magnetically attracted material to release the magnetically attracted material. There is also provided a method for clamping the magnetically attracted material (30) using the clamping device (10). The clamping device may, for example, be a device for securing a load to the magnetically attracted material, a lifting device, a device for holding a work piece in position, or a welding clamp. |
