摘要： A self-braking pulley is disclosed for controlling a rate of extraction of a tether wound upon the pulley. The pulley includes a spool for receiving a tether, the spool being arranged to rotate about an axle of the pulley as the tether is removed therefrom. The pulley further includes a braking assembly for applying a braking force to the spool and a drive assembly which is engagable with the spool via an engagement member. The engagement member is arranged to rotationally couple the spool with the drive assembly for driving the braking assembly, in dependence of a rate of rotation of the spool about the axle.

摘要： An abseiling device includes an annular spool with an inner surface, the spool being rotatable around a central axis. The spool includes an annular gear around its periphery with gear teeth facing the central axis. A line is wound around the spool, with one end fixed to the spool and the other end having an attachment mechanism. The device also has a shaft which is co-axial with the central axis and a centrifugal brake attached to the shaft. The centrifugal brake includes brake pads for applying a breaking force to the spool. The device also has a brake gear attached to the shaft, the brake gear being rotatable with the shaft, and a compound gear. The compound gear includes a first gear for engaging with the brake gear and a second gear for engaging with the annular gear. The first gear has a greater number of teeth than the second gear. When the spool is at rest the brake pad extends around over 80% of the circumference of the inner surface of the spool.

摘要： A fall protection device includes a frame, a rotation unit, a safety belt, a braking plate, a braking block and a restoring spring. The frame includes a first lateral plate, and a stopping block is formed on an exterior surface of the first lateral plate. The rotation unit is rotatably disposed with the frame. The safety belt is wound around the rotation unit. The braking plate is engaged with the rotation unit and includes an interior surface which faces the exterior surface of the first lateral plate. The braking block is pivotally disposed on the braking plate and located between the interior surface of the braking plate and the exterior surface of the first lateral plate. The present invention could ensure the braking block to abut against the stopping block as the braking block is at an expanding position, and thereby to improve a reliability of the lockup function.

摘要： A descender system, typically for use in a fall arrest system, for enabling a suspended body to be lowered includes a rotatable descent line drum, and a release element arranged in a restraint configuration to inhibit the descent line from being deployed and in a release configuration to permit the descent line to be deployed. A rotating brake applies a braking force to the rotatable descent line drum; a gear train connects the brake to the drum. The gear train is provided in a substantially watertight sealed space. Typically, a substantially watertight seal is provided between a backplate of the rotating drum and a chassis of the device. Typically, the substantially watertight seal is of a material that is deformable/compressible, preferably at temperatures at or below −20 Celsius.

摘要： A brake assembly for use with a retractable lifeline assembly comprises a brake hub, a pressure plate, a first friction disk, a brake plate, a second friction disk, and a lock nut. The brake hub includes a flange extending outward from an at least partially threaded shaft. The pressure plate is positioned on the at least partially threaded shaft proximate the flange. The first friction disk is positioned on the at least partially threaded shaft proximate the pressure plate. The brake plate is positioned on the at least partially threaded shaft proximate the first friction disk. The second friction disk is positioned on the at least partially threaded shaft proximate the brake plate. The lock nut is threaded onto the at least partially threaded shaft, and the lock nut is set to a desired torque at which the brake plate slips prior to final assembly of the retractable lifeline assembly.

摘要： An assembly includes first and second ropes and a suspension element. The first rope is securable to a first attachment in a work area. A person can be coupled to the first rope. The second rope is available for lowering the person. The suspension element is secured in a securing region. A force-transmitting coupling is creatable between the second rope and the suspension element. The first and second ropes are coupled to each other over a first lowering region. The second rope is decoupleable non-destructively from the first rope from an end of the first lowering region. A person can be lowered in a second lowering region by the second rope. The weight of the person in the second lowering region is transferable from the second rope via the suspension element to the securing region.
