摘要： An extension ladder includes sub-ladders and cushions. Each sub-ladder includes a rung s connected to two tubes. The tubes of each sub-ladder are telescopically connected to the tubes of an adjacent sub-ladder. Each cushion includes an air bag and a slow-release unit. The air bag includes an open end with a channel. The air bag of each cushion is inserted in a corresponding tube. The slow-release unit is operable to slowly release air from the air bag and includes a restraint and a membrane. The restraint is connected to the open end of the air bag. The membrane includes an aperture and is movable arranged between the restraint and the open end of the air bag, with the aperture in communication with the channel.

摘要： A ladder is provided which may include a positioning system, a fall arrest system, or both. In one embodiment, a rope and pulley system is provided wherein a first end of the rope is coupled to a base section of the ladder, a second end of the rope is coupled with a fly section of the ladder, and the rope extends between a plurality of pulleys. In one particular embodiment, the rope extends between five different pulleys, two being coupled with the fly section and three being coupled with the base section. At least one portion of the rope may extend along the side of the ladder (e.g., along the side of a rail of the fly section) while another section may extend up the front of the ladder between the rails and in front of the rungs. A fall arrest mechanism, or an ascender device, may be coupled with the section of rope extending up the ladder between the rails and in front of the rungs.

摘要： The present invention relates to an apparatus for providing ascent assistance comprising: a motive force generator; a motive force applicator operably linked to the motive force generator, and, in use of the apparatus, an object to which the motive force applicator applies a motive force, and a control mechanism comprising a load sensing means and a haulage force application means; said control mechanism being formed and arranged so as to control the motive force generator in a first, calibration, in which it detects a load applied to motive force applicator by the object and said haulage force is determined as a percentage of the applied load; the control mechanism being operable to switch the operation of the motive force generator into a second, assisted ascent mode. The invention further relates to a method for assisting a user in an ascent when working at height.

摘要： Disclosed is a modular safety ladder comprising a number of rungs connecting a first and a second guide rail, and an upper ladder module and a lower ladder module, said modular safety ladder being able to be arranged in an un-assembled configuration, in which said upper ladder module is un-attached to said lower ladder module, and an assembled configuration, in which said upper ladder module is attached to said lower ladder module, wherein each ladder module comprises a first and a second guide rail portion, and a rung connecting the first and second guide rail portions, wherein the modular safety ladder further comprises a spacer, the spacer in the assembled configuration being positioned to space apart the first guide rail portion of the upper ladder module from the first guide rail portion of the lower ladder module, and a tightening device which in the assembled configuration upon activation pulls said ladder modules towards each other, wherein at least a part of the spacer in the assembled configuration is positioned between a surface of the first guide rail portion of the upper ladder module and an opposite surface of the first guide rail portion of the lower ladder module so that tightening of the tightening device will squeeze or pinch or compress said at least a part of the spacer between said surfaces.

摘要： A centrifugal brake mechanism for a controlled descent device, and a drum device employing it, are described. The mechanism comprises a circular wheel configured and operable to rotate about an axis of rotation thereof, an axle extending along and rotatable about the axis inside a central cavity of the wheel and having two or more parallel shaft rods extending inside the cavity substantially perpendicular to the axis of rotation, a gear system for transferring rotations of the wheel into counter-rotations of the axle, one or more brake elements each having pass-through bores for slidably mounting over the two or more parallel shaft rods, springs mounted over the parallel shaft rods between the brake element and the axle, and a friction enhancement mechanism for increasing friction forces between the brake elements and the inner wall the wheel responsive to increase in angular velocity of the wheel.

摘要： A vertically orientated ladder apparatus allowing a climber to adopt an improved climbing stance wherein the climber's arms are poised economically in front of the climber within the climbing passage; the climber's legs are spread for the lateral stability of the climber so as to reduce the tendency of the climber falling sideways; and the climber is substantially upright such that the climber's centre of gravity lies substantially between the opposing steps (11) so as to allow the climber to release the climber's grip on the hand rails (14) while remaining balanced and supported by the legs of the climber. Opposing steps (11) are level or staggered. Embodiments include three or four stiles (12, 15).

摘要： A ladder supporting arrangement for stabilizing a ladder during use, comprising an elongated base member (10) mountable to a portion of a base ladder (2), and an elongated top member (35) which is configured to receive a portion of a working ladder (3). The arrangement is configured to be connected to the base and working ladders (2, 3) in such a way so that the working ladder (3) extends away from the base ladder (2) during use. The base member (10) is further configured to rotate about a pivot (45) connecting the base member (10) and the top member (35) in order to adjust the position of the working ladder (3) with respect to the base ladder (2).
