the following 13 items for the installation by WOS methos • • • • • • • • • • • • • 1-Install safety barricades blocking the hoistway opening to prevent any objects from flying or falling from the entrance opening 2-Install a protective cover to traction sheave and governor in machine room 3-Install a 90cm or more high safety handrail with intermediate handrail bar and kick plate to the upper/lower work platforms and install a removable gateway to the area facing to the hall 4-Install the ceiling to prevent any objects flying to upper work platform 5-Install a wire netting or curtain to the area facing to the CWT in the upper/lower work platforms to prevent the contact with CWT 6-Install a red warning lamp in the machine room to indicate that the power for elevator operation in on 7-Install an alarm buzzer in the machine room and car to inform the car operation 8-Install a key switch for the operation so that other workers cannot operation the car without permission 9-Use wire ropes which are cut into the predetermined length and inserted into the rope socket at both ends 10-Install a stopper on the CWT to prevent the CWT block from deflecting from the CWT guide rail 11-To install rail brackets in order with moving the gondola upward, install a contact segment for the overrun stop switch the the guide rail to prevent the bottom guide shoe from moving upward over the installation position of rail bracket is set 12-Install a nameplate to safety handrail in which the cautions such as maximum load, and the prohibition of work in upper/lower worker platforms at the same time are written 13- A chief installer using this method shall be the trained worker who participates in the classroom lecture and practical skill education held by the elevator manufacturer, and shall supervise and administrate the work SAFETY WORK STANDARD FOR ELEVATOR OPERATION • • • • • • • • • 1) Turn off before work Incase of elevators set side by side, check that the power of the appropriate elevato is turn off + Fatal accident case During the cleaning of sheave, a worker was pinched his finger by sudden movement of elevator because he turned off the power for the wrong elevator set side by side There is also a danger of electric shock 2) Do not touch the operating traction machine, governor, hydraulic pump motror, hydraulic V belt ect Fatal accident cases When one worker operated the car in low speed ridden on the car and stopped it, the other woker who cleaned ropes was caught by the sheave with a waste cloth Worker’s fingers ware caught between V belt and pump pulley in hydraulic elevators 3) Don’t enter pit or get on car top during automatic operation When a worker entered the pit during automatic operation , tha doors closed and the car ran downward 4) Take measures to prevent traction machine and governor operation during the work around them Turn off the power manually, and also turn off the governor switch for elevators with machine room or pit switch for machine-room-less elevators SAFETY WORK STANDARD FOR ELEVATOR OPERATION • • • • • • • • • • Before break releasing, change the operation mode to manual and turn off the power 6) In case the work is perfomed in machine room and the car seperately, use a comunication device such as intercom to give signals or instruction Check the elevator number, and receiver shall repeat signals signals and instruction Do not operate the elevator until receiver’s repetition or respond 7) After turning off the power, arrgane wires the inside the panel A worker got an eletric shock by touching the charging section during the arrangement of wires inside the panel 8) Do not perform the adjustment of hydraulic pipes during the work in hoisway When the oil leaks from pipes, the car goes down 9) During troubleshooting, not touch the main circuit for at least 30 seconds even if the power is turned off Check voltage by a tester and such before touching it Even of the power is turned off, the main circuit, espacially around inverter, is still charging electricity for a short time 10) In case of power failure, turn off the power after switching to manual mode and wait for the recovery of power supply After recovery of power supply, the car with emergency landing device or under automatic operation starts moving suddenly CAUTIONS FOR THE WORK ON CAR TOP • • • • • • • • 1) Do not assume that the car is always in expected position where the door opens when getting on the car top Fatal accident case When the door was fully opened at one push, a worker fell off by closing a balance Open the door a little and check if the car is on right position when a worker opens the door with the unclocking key Before getting on the car top, turn switch in car operating panel to manual and turn off all the switches on the car top from by keeping the hall door open Turn off the operation switch, door switch, and switch the mode from automatic to manual - Turn the switch in car operating panel to manual - Open the hall door 3) Do not stick out any body part from the handrail during operation After checking that all the body is inside of handrail, operate the car - Fatal accident case A worker’s head was caught between the handrail and the CWT while he was working with positioning his head to CWT side because he pushed UP button on the potable switch by mistake though he was going to push DOWN button 4) Give signals before operation, confirm the direction and check the partner’s repetion Inform which elevator is subject to operate in case of elevators set side by side Give signals such as “Slow up” “Slow down” and check the repetion CAUTIONS FOR THE WORK ON CAR TOP • • • • • • • • • • • • • 5) Do not work on the car top while the car is in automatic operation - A car starts moving without any calls in automatic operation The top clearance of the machine-roomless and hydraulic elevators is short 6) Keep in mind that if car moves upward, CWT moves downward Check the crossover point to prevent a worker from being pinched by CWT 7) Do not operate the car in case a worker on the car top cannot hear the signal from the machine room, pit and inside of the car - In case a worker cannot hear the signal, hypothetical judgment may cause a fatal accident In case he feels any danger, stop the work and restart the work after checking the safer way with other worker 8) For the signals for the low speed operation low speed operation “slow up” “slow down” For high speed operation, use “high speed up” “high speed down” 9) Do not jump to accident car directly In case moving to adjacent car, get out to the hall once and then ghet on the adjacent car A worker was almost to pinched when the car moved suddenly Also there is danger of falling 10) In case of elevators set side by side, not lean over to other elevator side 11) In case of parallel work, adjust the car position so that wokers on the car top can check each other by sight 12)During inspection, if a worker is instructed to wait at the top floor during operation inside the car, wait there and switch the operation mode to manual after landing CAUTIONS FOR THE WORK ON CAR TOP • • • • 13) In case leaving the car by the halt of work, turn off all the switches inside the car then close and clock the sevice cabinet of the operating panel Close the hall door so that unauthorized person cannot

car, then close and lock the service the cabinet on the car operating panel CAUTION FOR WORK IN THE PIT • • • • • • • • • • • • *Check if this floor is the bottom floor Fatal accident case A worker fell down to the pit from the intermediate floor because he assumed to be at the bottom floor Turn on the light of the car and pit * Do not go in the pit while the elevator is in automatic operation Stop the car the upper floor, turn the switches in cae operating panel as follow: Operation Switch OFF ; Auto/Manual switch Manual, door switch OFF Anh close hall door In case a worker goes in the pit, turn off the pit switch and switches inside the car *Basically, not perform any work during operation However, if it is nescessary to operate the car during the inspection and the work in the pit * To go in or out the pit, pay attention to the treads of leader to be slippery with oil an such * In case of the work in the pit with operating the car manually, communicate with the workers surely and pay special attention to the movement of car, governor tension sheave, CWT, traveling cable, and ropes etc , governor, puly căng cáp (tension sheave), CWT, cáp di động, dây cáp … Safety check and
