Platforms according to one embodiment of the invention include an extendable mast connected to a skid via a linkage that allows pivoting of the mast with respect to the skid, and preferably does not permit rotation of the mast; at least two actuators connected to the mast; at least one inclination sensor; at least one detection sensor connected to the mast for detecting presence of an object; and circuitry that receives information from the inclination sensors and plumbs the mast. Coupling and actuator mechanisms are disclosed for connecting the mast to the skid in a manner that allows the mast to be stable for accurate use of the sensors, yet easily and quickly deployable for such use, whether the platform is deployed from the bed of a truck or when the skid is on the ground and the mast is fully extended.

  • Patent number: 7568557
    Abstract: A portion of an elevator car electrical system, such as car computer, terminals, communication apparatus, etc., is mounted in an apparatus space integrated into a car roof. The apparatus space is arranged along a car roof edge and utilizes a constructional height required for stiffening the car roof. The portion of the car electrical system is accessible by a moveable cover for service. When closed, the cover forms a standing surface which can be used for servicing in the elevator shaft.

  • Patent number: 7554278
    Abstract: A load-lifting apparatus has one or more prime power sources, one or more energy storage systems and regenerative braking. Regenerative energy is recovered when the load-lifting apparatus lowers its load. The elements of the prime power sources, energy storage devices and electrical components may be distributed to provide stability for the load-lifting apparatus. The general power architecture and energy recovery method can be applied to cranes, rubber-tired gantry cranes, overhead cranes, mobile cranes, ship-to-shore cranes, container cranes, rail-mounted gantry cranes, straddle carrier cranes and elevators. In such an architecture, the energy storage system helps alleviate the power rating requirement of the prime power source with respect to the peak power requirement for lifting a load.

  • Patent number: 7506725
    Abstract: The rolling friction force of ball screw is much small than the sliding friction force of it. Using ball screw as the transmission mechanism for elevator, so as to find the differences of friction forces between rolling motion and sliding motion. Besides, the current of motor has the obvious relationship to the driving force of motor, we use current of motor for ball screw type elevator to monitor the system. And, before the serious damage occurring, the monitor system can find the different form the current of motor, and make the operation for elevator safer.

  • Patent number: 7506728
    Abstract: A connector device (40) for making electrically conductive connections with at least one tension member (32) in an elevator load bearing member (30) includes a spacer member (42) that establishes physical spacing between portions (38) of the load bearing member (30). In one example, each portion (38) includes one tension member (32). A holding member (50) secures the portions (38) in a selected position relative to the connector device. At least one electrically conductive connector member (70) makes electrically conductive contact with at least one of the tension members (32) to facilitate a selected electricity-based monitoring technique for accessing the condition of the load bearing member.

  • Patent number: 7500650
    Abstract: An improved lift system door control or safety circuit utilizes locking devices for the lift shaft doors and lock sensors to monitor the status of the locking devices. The lock sensors are coupled to a lift drive unit control through a data bus, which need not be especially designed as a safety data bus. The lock sensors are repeatedly interrogated at short term intervals. The status of the doors is interrogated on a longer time interval, and such data is also passed to the drive unit control by the data bus. The interrogations are used to determine the operating condition of the locking sensors as well as whether communications or transmission errors are present.

  • Patent number: 7500543
    Abstract: A coupling arrangement for coupling a traction sheave on a motor shaft includes a taper lock bushing and a traction sheave having a tapered bore adapted to receive the taper lock bushing. The taper lock bushing is sized to slidingly engage with the motor shaft and to fit into the tapered bore of the traction sheave. The taper lock bushing is fastened onto the traction sheave via threaded fasteners to result in a compression fit between the taper lock bushing and the motor shaft.

    Abstract: An encoder failure in an elevator drive system is detected and managed. A velocity of the elevator drive system is provided by an encoder signal (60) and compared with a minimum velocity threshold (62). An encoder fault timer is incremented when the velocity is less than the minimum velocity threshold (64). The elevator drive system is disabled when the encoder fault timer reaches a fault threshold time (66).

    Abstract: A lift drive unit has at least one monitoring device for monitoring unallowed raising of a lift cage. The drive unit has a motor unit and a deflecting unit. If a counterweight supported by the deflecting unit, for example rests on a shaft pit buffer, the deflecting unit is unloaded and is raised by means of a spring element of the monitoring device. A sensor of the monitoring device detects the movement of the deflecting unit and switches off the motor of the motor unit via a safety circuit.
