LIST OF TECHNICAL TESTS & CHECKS CARRIED OUTAnnex to inspection report no. …………../…………………..
Crt. No.
Description of operations carried out If technical requirement is fulfilled
Control procedures applied Observations
Yes No N/A Visual Tested Measured1. Elevator identification 1.1
1.2
● Check of registration plate and the existence of CE marking: Manufacturer name: …………………………………………………………….…..Model :. ……............................................., Type: ............................................., Serial no..: ............................................., Year of fabrication: ...............................,Qnom. (rated load) = ............................. kg, No. of persons: ….........., No. of stops = …............, No.of accesses = .........…..,- with 1 speed: V rated = ...... m/s, with 2 speeds: V rated/slow = ......../…….. m/s,- wirh variable speed ● Check of warning / emergency signs
2. Technical inspection2.1 - technical book of elevator
- if the maintenance work is carried out by an ISCIR’s authorized company - if the maintenance personnel is trained - degree of elevator preparation for technical inspection
2.2 Under going inspection
2.2.1 ● Check of safety components (identification): - landing doors locking devices ......pcs. - safety gears ......pcs. - overspeed governors ......pcs. - end limits safety switches (devices) ......pcs. - hydraulic buffers ......pcs. - rupture valves ......pcs. - electric safety contacts (safety circuit breakers) ......pcs.
2.2.2 ● Functional testsNew elevators - check of landing doors locking devices - check of electric safety devices (contacts, circuit breakers etc.) - ckeck of end limits safety switches (devices)- check slippage of ropes - check of overspeed governor - check of counterweight’s safety gears - check of car alarm - check of emergency lighting system
