摘要： A safety device of an air balancing hoist according to the present invention is provided to instantaneously brake a reel drum in the manner that a braking pawl mounted to be rotatable on an end cap is pushed to the outside direction of the circumference of a circle by centrifugal force to be locked into a ratchet wheel fixed on the end cap when the reel drum is suddenly fast rotated during a hoisting process. The safety device of the air balancing hoist comprises a housing including a chamber in which compressed air is induced/discharged; a piston connected into the inside of the housing to be slidably reciprocated; a ball screw penetrating the piston and including both ends fixed not to be rotated in the housing; a reel drum rotated along the ball screw upon movement; a ratchet wheel in a ring shape mounted on an inner side surface of an end cap formed at one end of the housing; a braking rotor mounted in the center of the end cap to be rotatable; a braking shaft, wherein one end is fixed on the rotor and the other end is connected with a fixing hole of the reel drum; and a braking pawl, wherein one end is elastically inserted in the braking rotor to be pivotable in the circumferential direction and the other end is fixed by a hinge on the braking rotor.

摘要： A balancing hoist, includes a housing having a chamber accessible from outside. Received in the housing is a piston which is movable by gas pressure in a longitudinal direction and rotates a threaded spindle which projects into the chamber of the housing and carries a nut that securely fixed to the housing. Mounted in fixed rotative engagement to the spindle and movable longitudinally along the spindle is a cable drum on which a load-carrying cable is wound. At least one pawl is provided and configured for rotation in opposition to an elastic restraining force from a radially inward idle position to a radially outward brake position as a result of centrifugal forces, when a rotation speed of the cable drum exceeds a predetermined level, thereby impacting upon a fixed stopper which projects radially inwardly from the housing and slowing down the rotation of the cable drum until it is at rest.

摘要： In order to increase the operational safety and to reduce the rope wear, hoisting/lowering apparatus comprise one or a combination of novel features: an adaptor (3) is provided in order to allow the attachment of accessories (50), preferably by insertion. Possible accessories are e.g. holders having a loop for the attachment of hooks, and single or multiple blocks for the formation of lifting blocks. Substantially, the adaptor is formed of a number of slot-shaped recesses which are transversely traversed by rod-shaped retaining elements (11, 9). One of said retaining elements (9) is displaceably mounted in order to allow the attachment resp. detachment of an accessory (50). Another measure is to provide a rope stop (102) on the traction side. The rope (103) runs through the rope stop (102) and drives a knurled wheel (110). At a given rope speed, the wheel is coupled to a pivotable brake appendix (118) by means of a centrifugal coupling (113, 115). The rope (103) is then squeezed and blocked between the appendix (118) and a counterpart (108). A third measure consists in providing guiding rolls (36, 37) in order to ensure a spiral-shaped travel of the rope (103) which is free of crossings.

摘要： An elevator drive machine includes a speed reduction unit, a driving sheave, and the first and the second driven sheaves formed over the driving sheave and arranged a triangle with the driving sheave. Each of the sheave has ratchet on its periphery, a pawl mechanism is mounted near the sheave. A speed limiter which includes a centrifugal speed limiter engaging with the gear of the first driven sheave and a three-branch lever, is provided on the side of driving sheave and the first driven sheave, When the dropping speed of the cab overruns the given speed, the three-branch lever moves so as to make the ratchet engage with the pawl, thus braking the driving sheave and the first driven sheave, quickly increasing the friction force of driving rope and immediately stopping the cab. It can prevent the rope from sliding on the sheaves, and has advantages of compact construction and low cost.
