摘要:
An elevator system is a one-shaft double-car elevator system and includes a floor-recognition abnormality detector to detect, with respect to one of the cars, a floor recognition abnormality that at least one of a car position and floor information cannot be normally recognized, a terminal-floor driving mechanism to make, on the basis of a notification of floor-recognition abnormality information detected by the floor-recognition abnormality detector, the other one of the cars travel to a terminal floor in a direction opposite to a direction toward the one of the cars, and a floor-recognition-abnormality correcting-operation mechanism to perform, on the basis of terminal-floor traveling information from the terminal-floor driving mechanism, a floor-recognition-abnormality correcting-operation to correct the floor recognition abnormality of the one of the cars; therefore, an operation to recover from the abnormality can be safely performed without collision of the cars.

A wind turbine tower with an elevator system and a method to install the elevator system is provided. The tower for a wind turbine comprises includes an elevator system including guide wires. The guide wires are connected to a guide wire fixture arrangement. The tower includes a platform that is arranged in the area of the lower end of the tower. The platform comprises an opening to allow the guide wires to pass through the opening. The platform includes a connection means, to detachably connect the guide wire fixture arrangement to the platform during transportation and installation of the tower. The platform includes a hoist system to lower the guide wire fixture arrangement through the opening in the platform into a space below the tower to extend the guide wires through the opening in the platform.

A height access device enables motorized access to the driving station of a tower crane atop a mast formed of superposed mast elements. It includes a lift cabin installed inside the mast of the crane and movable vertically along the mast. The height access devices further includes a working platform positioned above and separably connected to the lift cabin. A coupling device provides a non-permanent connection of the working platform to the lift cabin and immobilizes the working platform relative to the mast at a required height. The height access device enables the crane driver to ascend and descend with the lift cabin alone when disconnected from the working platform and with the lift cabin and working platform together, particularly during the assembly and dismantling of the mast.
摘要:
An apparatus designed for climbing poles, trees and other such columnar objects. The apparatus is a remote-controlled work station that provides a scaffold for mounting semi-robotic articulated arms and video cameras. The articulated arm has a quick-release coupler on an end thereof that is able to repeatedly and releasably couple attachments thereto, such as saws, blades, and other pruning objects. The device includes an expandable frame that may be opened and closed to fit around the vertical structure to be climbed. The frame has horizontal and vertical supports, drive system compression supports, and wheels. A drive system is mounted to each of the drive system compression supports. The drive system includes motorized tracked-climbers that are maintained in contact with the vertical structure to be climbed via adjustable independent suspension. The suspension uses adjustable spring shocks and drive system slide rails to connect the frame to the drive system.

A system and method for interfacing a destination entry system (2) with existing security infrastructure of a space is disclosed. The destination entry system (2) may include at least one destination entry device (22) configured to receive a destination request from a user and an interface device (26) to facilitate communication between the destination entry system (2) and a security system (27). The interface device (26) may be configured to receive credentials of the user from the security system (27), co-relate the credentials with areas within a space that the user is authorized to access, identify which one of the at least one destination entry device (22) originated the destination request from the user and communicate the authorized areas and the identified one of the at least one destination entry device (22) to the destination entry system (2).
摘要:
An elevator system includes an elevator car located in a hoistway. One or more belts are operably connected to the elevator car to drive and/or support the elevator car along the hoistway. The one or more belts are routed over one or more sheaves. The one or more sheaves include an outer surface rotatable about a central axis and a flange located at at least one lateral end of the sheave. The sheave further includes a tracking compensator to limit lateral motion of the belt along the outer surface to prevent the belt from contacting the flange.
摘要:
An elevator includes a car and a counterweight suspended on hoisting ropes which are driven by a drive machine. The counterweight has a first side facing the elevator car path and a second side opposite to the car path. The counterweight includes at least one connecting passage between the first and second side of the counterweight. With this solution, air pressure built between the car and the counterweight when passing in the elevator shaft is reduced and the travel comfort is improved.

The disclosure is related to systems and methods regarding transit and movement of people. The Articulated Funiculator is a continuous and connected system of trains that moves people in mass. The trains lie horizontal at specific floor levels (designated as stations) in tall buildings or underground levels (designated as stations) in mining operations and underground subway stations. The Articulated Funiculator transitions from horizontal alignments at the stations to vertical, slanted or curved alignments between the stations, albeit the passengers remain horizontal in a standing position. The Articulated Funiculator captures the energy from the braking, dynamic braking’ of the trains and stores it. The stored energy is then used to accelerate the Articulated Funiculator. This re-use of energy makes the Articulated Funiculator sustainable.

An elevator includes a hoistway, and an elevator car and a counterweight vertically movable in the hoistway. The elevator includes at least one first stationary mounted rope wheel positioned in proximity of the upper end of the hoistway, and at least one second stationary mounted rope wheel positioned in proximity of the upper end of the hoistway, the at least one first stationary mounted rope wheel and the at least one second stationary mounted rope wheel being horizontally spaced apart and rotating on different vertical planes of rotation, and a roping, including at least one belt-shaped rope interconnecting the elevator car and counterweight and including a rope portion extending between the car and counterweight, which passes around the at least one first stationary mounted rope wheel and around the at least one second stationary mounted rope wheel, and at least one intermediate stationary mounted rope wheel, positioned at a distance apart from the at least one first rope wheel and the at least one second rope wheel to rotate on a plane of rotation that intersects the plane of rotation of the at least one first rope wheel and the plane of rotation of the at least one second rope wheel, and arranged to guide the portion of the rope extending between the at least one first rope wheel and the at least one second rope wheel to pass from the plane of rotation of the at least one first wheel to the plane of rotation of the at least one second wheel along the plane of rotation of the at least one intermediate stationary mounted rope wheel.
