Maintenance of E.I. in Non Residential building at U.T Chandigarh. (Replacement of existing damaged hoisting rope and defunct PCBs in existing elevator installed in Infosys foundation Red Cross Sarai Building at PGIMER campus, sector 12 at U.T Chandi

Supply, installation, testing and commissioning of following damaged/defunct parts in existing elevators installed in Infosys foundation Red Cross Sarai Building at PGIMER campus, sector 12 at U.T Chandigarh. The following parts are as under:-

Supply, installation, testing and commissioning of Control Panel PCB M1 in the existing elevator. The Control Panel PCB M1 is a sophisticated, multi-functional board central to every aspect of elevator operation, blending processing power, safety features, and communication capabilities. The Control Panel PCB M1 should be imported from the Japan. The main function of the control panel is to control the Power circuit and ARD circuit in the existing elevator. The Control Panel PCB M1 should be of Mitsubishi make only. (Qty 1 No.)

Supply, installation, testing and commissioning of Car Station PCB DOR in the existing elevator. The Car Station PCB DOR (Door Operation Relay) of a lift is an essential part of the elevator control system responsible for managing the opening and closing of the lift doors. The Car Station PCB acts as the communication interface between the lift car’s control panel and the main controller. The DOR circuit or relay on this PCB ensures that the doors operate safely and efficiently by sending signals to the door motor controller based on user commands or system logic. The Car Station PCB DOR should be imported from the Japan. The main function of the Car Station PCB DOR is to open and close the door in the existing elevator. The Car Station PCB DOR should be of Mitsubishi make only. (Qty 1 No.)

Supply, installation, testing and commissioning of 10 mm Rope in the existing elevator. The hoist ropes or lift ropes, are essential components of elevator systems designed to support and move the elevator car within the shaft. These ropes are typically made from high-strength steel wires twisted into strands and then around a core, either steel or natural fiber, to form a robust and flexible cable. The primary function of elevator ropes is to safely handle the weight of the elevator car, passengers, and additional loads while enabling smooth and reliable up-and-down movement. The ropes run over a traction sheave connected to the motor drive system, which controls elevator movement through rotation. For safety, a governor rope is also used as part of an overspeed governor system to prevent the car from moving too fast by activating brakes in emergencies. The approximate length of the rope 35-38 mtr each and the total length of the Nos. 10 mm Rope is 140-150 mtr should be installed in the existing elevator. The rope should be imported from the Korea. The main function of the elevator hoisting ropes is to support, lift, and lower the elevator car and its counterweight within the elevator shaft. The rope should be of KIS Wire make only. ( Qty 140-150 mtr.)

The job includes the cost of dismantling of existing hosting rope control panel & car station PCB’s required to complete the job. The job also includes the cost of labour, making connection and other petty material required to complete the job to the entire satisfaction of Engineer in charge of the work. The above said material of the elevator should be as per equipment no.10011073 and 10011074 mentioned in the quotation only.

The job includes installation, testing and commissioning as required to complete the work in all respect including cost of all material, T& P, Carriage and labour etc. The job also includes cost of all civil work at the site as required at no extra payment.

The complete lift including testing commissioning and safety provision shall conform to various Indian standards and rules with upto date amendments as mentioned below:- i.IS 14665 (Part 1 to 3) 2000. ii. IS 14665 (Part 5) 1999. iii.As per CPWD and relevant IS codes.
