Abstract: The maritime transfer system is for crewmember safety when transferring to and from a vessel to a small oil or gas production platform that otherwise has only a swing rope for transfer. The system includes a platform extension permanently affixed to the platform, and a motor and winch installed on the extension. The motor and winch operate a cable that extends to a davit, the davit and cable suspending a car or gondola therefrom. Control is provided by a remote control switch installed on the distal end of a freely suspended control cable. In this manner, the car may be raised to the platform when not in use, the control hanging from the control cable for access from the crew vessel when needed. The crewmember may then carry the control with him or her in the car as it is raised and lowered to and from the platform.

The system incorporates at least one hoist attached to the work platform and in electrical communication with a hoist control system that may have a data transmitter to transmit data to a remote location, a data receiver to receive data from the remote location, and/or a monitoring and diagnostic system to monitor and record at least one of a plurality of operating characteristics of the hoist. The hoist control system may also include a GPS tracking device that transmit a hoist location and may prevent operation of the motor if the hoist location is not in an authorized area of operation. The hoist control system may further include a safety lock out system that requires authentication of an operator prior to the hoist control system causing movement of the hoist system.

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.

Abstract: An emergency escape apparatus for elevator is disclosed. In response to power outage manually pulling an actuation rope will pivot a pivot bar counterclockwise to rotate front and rear cams, press front and rear cams onto front and rear actuation members respectively, lower a pinion to be in mesh with a gear on a front of a drive sheave, press pressing rollers onto hoist ropes, activate a bar member to deactivate a brake, close a switch, and activate a backup motor to turn the pinion and the drive sheave through the gear, thereby lowering a car until a safe floor is reached. In another operation speeding the car will automatically enable an electromagnetic actuator to pull the actuation rope and activate a main motor to lower the car.

Abstract: Provided is an elevator escape device. In response to a stop of the elevator due to power outage, a trapped person may press a switch to activate a backup generator, and either a backup electromagnetic contact is enabled if the backup generator functions normally or the person manipulates a handle to activate a slow movement assembly if the backup generator malfunctions. Thereafter, the brake is disabled by contacting a first detent a return assembly operates to return a slow movement assembly to its nonoperating position via a control assembly wherein electromagnetic contacts are short-circuited sequentially by contacting corresponding electromagnetic contacts, the car slowly arrives at a nearest correct floor, and the trapped person may to open a door to escape.

Abstract: Disclosed is a return mechanism for elevator escape device. The return mechanism mounted at a wall of a car and comprises a drive sheave, upper and lower secondary sheaves, a wheel coaxially disposed with the drive sheave and located on an inner wall of the car, a lever including a lower pivot end, a positioning bar, an upper end at the drive sheave, and a groove, a link having one end defined by the groove and a roller at the other end, a support for permitting the link to slide therethrough, a catch, and projecting return members. In a case of car failure, a trapped passenger is able to continuously rotate the wheel for escape in which the mechanism can automatically return to its original position by moving the link backward after the roller contacting the return member.

Abstract: An emergency safeguard system for elevator includes an emergency push-button disposed in the elevator car applied to cooperate with an auxiliary control panel and an auxiliary door opening system, furthermore, on the elevator car and in the elevator shaft are provided with photoinduced system and positioning and direction judging system, such that the stranded users are able to extricate themselves from the elevator car under an automatic and safety program.

Abstract: An elevator including a cage configured to ascend and descend along a guide rail in an elevator shaft, a drive unit configured to move the cage up and down, and an emergency stop device configured to urgently stop the cage when the cage descends at an extraordinary speed. The emergency stop device including an emergency stop mechanism provided at a lower end portion of the cage and configured to engage the guide rail, thereby urgently stopping the cage, a link mechanism provided at the lower end portion of the cage so as to be located close to the emergency stop mechanism and configured to actuate the emergency stop mechanism on receiving an external input, and a speed detector configured to detect the descent of the cage at the extraordinary speed and correspondingly to apply the external input to the link mechanism.

Abstract: An improved top of car inspection station includes warning circuit for providing a warning signal whenever the elevator car is in the inspection mode and the emergency stop switch is deactivated and the mechanic is not commanding the car to move.

Abstract: An emergency lifting or lowering device of an elevator includes a transmission toothed wheel fitted to a top of a passage receiving a carriage of the elevator. The transmission wheel has teeth locking into an adjacent one of several toothed wheels arranged in a low. The toothed wheels are each associated with a reeling member having first end portions of steel ropes of the elevator wound therearound. The emergency lifting or lowering device further has an emergency switch disposed in the carriage member, and electrically connected to an emergency power to activate the transmission wheel in order to lift or lower the carriage member to a nearest floor when a main motor of the elevator stops due to power failure.
