1 Solution Specifications Freight Elevator Technical Equipment Data Equipment-No. Freight #1 Rated Load lb Rated Speed 150 fpm Travel Height 40 ft 0 in Number of floors All Proposals offered shall be comprised of design, manufacturing, supply and installation of following unit(s). Besides the technical specification we would highlight the key inclusions mentioned below. Offered Components Power Freight Traction Controller Hoist Motor Miscellaneous Existing freight doors to be retained and reused, new door interlocks to be provided as needed. Provide microprocessor-based control system to perform the functions of safe elevator motion. Included shall be all of the hardware required to connect, transfer and interrupt power, and to protect the motor against overloading. Each controller cabinet containing memory equipment shall be properly shielded from line pollution. The microcomputer system shall be designed to accept reprogramming with minimum system down time. All high voltage (110V or above) contact points inside the controller cabinet shall be protected from accidental contact in a situation where the controller doors are open. A new hoist motor shall be provided. The motor will be designed to stand the loads encountered for elevator service, sufficient capacity to operate with the contract load and speed without overheating, and will be rated in accordance with the standards of the IEEE. New Traveling Cable, Hoistway Wiring, Car Top Handrail Guides Governor New roller guides shall be provided. The car safety will be activated by a new speed governor located overhead, driven by a governor rope suitably connected to the car safety. The governor will be equipped with rope grip jaws designed to clamp the governor rope so as to actuate the car safety upon a predetermined over speed downward. The governor will be set at not less than 115% of specified rated car speed and not more than the maximum governor tripping speed specified in the code for the specified rated car speed. The rope grip jaws must be positively tripped within the permitted range of speed. The governor rope-tripping device will be so designed that no appreciable damage to or deformation of the governor rope will result from the stopping action of the device in operating the car safety. The governor over speed switches will conform to ANSI

2 A17.1 Code requirements and be so located and enclosed that excess lubricant will not enter the switch enclosure. Upon activation of the safety switch, the switch will remain in the open position until manually reset. The governor will be accurately adjusted and sealed with tripping speed specified. Date tags indicating the test date will be applied. Governor Ropes Hoist Ropes Rope Gripper Signalization Included Options A new governor cable(s) compatible with the specifications for the new governor will be provided. The governor cable is to pass over the governor sheave and under a weighted tension device at the bottom of the hoist way. During normal operation of each elevator, the governor rope will run free and clear of the governor gripping jaws, cable guards and all other stationary parts. A metal tag will be attached to the top of the car-releasing carrier, giving the diameter, material of cable, and with date of cable installation. Tags will be attached in an approved manner. New hoist cables shall be provided. The hoisting cables will be designed for elevator service, compatible with the hoist machine, and having a factor of safety at least equal to that specified in the ANSI Code. A new rope gripper over speed device shall be provided. The rope gripper shall prevent the car from striking the hoistway overhead structure due to a failure in the hoist motor, brake, coupling, shaft, gearing or control system. The rope gripper will be set to detect an ascending car over speed condition at a speed not greater than 10% higher than the speed at which the car governor is set to actuate. The device will also detect unintended car movement away from the landing with the hoistway door not in the locked position and the car door not in the closed position. The rope gripper will be designed so that no appreciable damage to, or deformation of, the cables will result from the stopping action of the device. Once activated by unintended movement or car over speed the device will remain activated until manually reset. New signalization in the hall and car shall be provided as required. 1 pc.

Specify delivery lead time in proposal. Downtime period Specify down time per unit in proposal. CLARIFICATIONS

3 Contractors shall be responsible for all Permitting. All elevator equipment provided shall meet all applicable ASME A17.1 code requirements including all emergency phone requirements. Proposals shall include all inspections and testing as required by the Authority Having Jurisdiction as well as the fees associated with them.
