3.7.1 Where the lifting appliances are to be assigned a class in the Register Book the Initial Surveys are to be carried out in accordance with 3.2 or 3.3 as appropriate. When the required reports on completion of the survey have been received and approved by the Committee, certificates of classification of the lifting appliances will be issued.

3.7.2 It is the responsibility of the Owner to ensure that all surveys necessary for the maintenance of class are carried out at the proper time and in accordance with the instructions of the Committee. The Society will give timely notice to an Owner about forthcoming surveys by means of a letter or quarterly computer print-out. The omission of this notice, however, does not absolve the Owner from his responsibility to comply with LR's survey requirements for the maintenance of class.

3.7.3 Periodical Surveys for the maintenance of class are to be carried out by LR's Surveyors in accordance with 3.4.

Certificates of class maintenance in respect of completed Periodical Surveys will be issued to Owners on application.

3.7.4 It should be noted that the intervals between Periodical Surveys of lifting appliances are determined by Statutory Regulations and deferments cannot exceed those permitted by 3.5.

Survey

Where weathertight seals are fitted satisfy yourself that their general condition is satisfactory and check their effectiveness using a water spray test or other suitable method

(i) Re-testing of the lift or ramp is necessary at 4 or 5 yearly intervals as appropriate and when repairs have been carried out affecting the strength or as required by the Surveyor

(ii) It is essential that the lift or ramp is operated at each survey throughout the full operational range for each mode of operation and to check that the limit switches, interlocks, guards and safety devices operate satisfactorily

Survey

(i) Check that the reeving of wire ropes and chains, and the arrangement of hydraulic cylinders is as shown on the appropriate plans

(ii) Check that the plate indicating the allowable load mounted inside the lift is in agreement with the appropriate plan and as indicated in the 'Register of Ship's Cargo Gear and Lifting Appliances (i) Determine that sheaves, sprockets and guide rollers, etc., are free from cracks or scores and that

they are free to rotate

(ii) Survey rope grooves for scoring and sprockets for signs of abnormal wear, hooking, etc.

(iii) Check that lubrication arrangements are in working order

(iv) Check axle pins and bearings with regard to deformation and excessive wear (i) Survey condition of ropes

(ii) Check for broken, worn or corroded wires. In general, the rope is to be replaced if the number of broken, worn or corroded wires exceeds the limit given in Table 9.3.2

(iii) Survey terminal fittings, splices, etc., with particular attention to broken wires at ferrule connections.

Any serving on splices is to be renewed for this examination

(i) Survey the chain, which is to be sufficiently free from grease and scale, etc., to enable a satisfactory examination to be made

(ii) Check for deformation, wear or other defects. If links require renewal the chain is to be suitably heat-treated and re-tested. Replaced links are to be of equivalent material and strength to the original

(iii) Confirm that material is recorded on the test certificate. The certificate should distinguish between mild steel, higher tensile steel and alloy steel

(i) Survey for leaks and check condition of hydraulic pipes

(ii) Check pistons, pivot pins and bearings, etc., for excessive wear and deformation (iii) Determine that sheaves are free from cracks or scores and are free to rotate (iv) Check that mounting brackets are free from deformation cracks or damage (I) Check that the landing and car doors operate satisfactorily

(ii) Check that interlocks on the doors operate effectively

(iii) Survey the door and check that its fire resisting capacity is unimpaired

(i) Examine the car and counterweight for damage which could affect their operating efficiency or carrying capacity

(ii) Check that brackets for sheaves, guide rollers, wire terminals, etc., are secure and in good order (iii) Survey the car and check that its fire resisting capacity is unimpaired

(i) Check that the lift trunk and well are free from debris or damage which could impair the satisfactory operation of the lift

(ii) Check that trunk has not been damaged, is suitably ventilated and is totally enclosed such as to prevent passage of smoke and flame from one deck to another

(i) Check that the car and counterweight guides are not worn or distorted and that the joint plates are secure

(ii) Check that brackets attaching guides to trunk are in good order (iii) Check that buffers are in good order and supports are sound

Check that over-running devices and brakes are operating satisfactorily and are in good order

Check that safety gear for preventing the car from falling is secure and in good order (i) Check that escape hatches, ladders, etc., are free from obstruction and in good order (ii) Check that the emergency telephone and warning system operate satisfactorily (iii) Check that all warning notices, etc., are legible and secure

(i) Re-testing is necessary at 4 or 5 yearly intervals as appropriate and when repairs have been carried out affecting the strength or as required by the Surveyor

(ii) It is essential that the lift is operated at each survey to check that limit switches, interlocks and safety devices operate satisfactorily
