The invention relates to a device (10) for safe access to a confined space, comprising: a rectilinear support strut (12), two arms (14, 16) each fixed rigidly to an end (12a) of the strut, at right angles thereto and in opposite directions. A first arm (14) comprises at least one anchoring element (18), the second arm (16) being provided with at least two pulleys (20, 22) whose axis of rotation is at right angles to the plane defined by the strut and the arms. The anchoring element (18) and the two pulleys (20, 22) are arranged so as to allow the passage of a cordage of the anchoring element to the pulleys without interfering with the strut and the first and second arms. The strut (12) has at least one fixing member intended to cooperate with an opening (84) of the confined space in order to ensure the fixing thereof.

A control device that controls an electric hoisting machine includes: a tension sensor that detects tension of a pulling member; a mode input unit that inputs a mode switch signal to switch between a winding mode and an unwinding mode; and a control unit that controls the operation of a electric motor. The control unit, when set in the unwinding mode, controls the electric motor in accordance with a detection signal from the tension sensor to cause the rotating body to be inversely rotated when the tension of the pulling member is not less than a predetermined threshold value, and to prevent the rotating body from being inversely rotated when the tension of the pulling member is lower than the predetermined threshold value.

An apparatus for installing and removing glass panels and methods of using the apparatus are disclosed. The apparatus includes a base portion, a back support structure secured to the base portion, and a glass adjustment system moveably coupled to the back support structure. Methods for using the apparatus to install and remove glass panels from, for example, ice rink boards, are also disclosed.

A maintenance apparatus, in particular for lifting and moving components of a system for processing semiconductor devices. The apparatus comprises a beam and an arm with means for lifting a component, the arm being mounted to the beam via a connecting unit and so as to be pivotable in a horizontal plane, wherein the connecting unit is displaceable along the beam, and wherein the arm is displaceable perpendicularly to the beam, and wherein a load accommodation means is provided on the pivotable arm.

A lifting apparatus for a facility combining magnetic resonance imaging apparatus and radiotherapy apparatus inside a purpose-built structure having a fixed wall, the lifting apparatus comprising a wall-mounted articulating jib crane which is selectively moveable between a stowed state and a free state in which it is operable as a crane, in which substantially all of the load-bearing parts of the crane are made of non-ferromagnetic metal, and in which guides are mounted to the wall to receive and to releasably hold the crane in a fixed position relative to the wall when the crane is in the stowed state.

A lifting apparatus for mounting on an upper edge of a wall to transfer an item from a location on a first side of the wall to a location on a second side of the wall. The lifting apparatus may include a wall mounting assembly configured removably mounting on a portion of the wall including and adjacent to the upper edge of the wall. The wall mounting assembly may include a saddle structure configured to create a receiving space for receiving the upper edge of the wall and a portion of the wall adjacent to the upper edge of the wall. The lifting apparatus may also include a davit assembly mounted on the wall mounting assembly and configured to facilitate lifting of an item adjacent to a wall on which the wall mounting assembly is mounted.

An apparatus for installing and removing glass panels and methods of using the apparatus includes a base portion, a back support structure secured to the base portion, and a glass adjustment system moveably coupled to the back support structure. The glass adjustment system couples to the glass panels. The apparatus is used to install and remove glass panels from, for example, ice rink boards.
