1. Hazards 1.1 Hazards in normal operation When the elevator is activated, everyone must maintain a sufficiently safe distance. During incorrect use of the elevator, danger of life-threatening injury exists.

When the elevator opens and closes, there is an increased danger of being injured, near the body and the latch. The elevator must never be used without bushings. Before working on the bushings, make sure that no hydraulic pressure is applied to the elevator and that the connecting lines are uncoupled.

WARNING This product could be hazardous if improperly used. It must be properly installed and maintained in order to function properly. Do not weld or alter without Blohm+Voss Oil Tools’s prior authorization. If replacement parts are needed, they have to be ordered from Blohm+Voss Oil Tools.


5

1.2 Hazards caused by misuse and improper use Both the utilised bushing segments must always be labelled with the same seriel number and pipe size (see Fig.1). Even when the bushing size is the same, bushings with different serial numbers must never be used. There exists the danger that the elevator will rise and/or the pipe will fall out due to different amounts of wear.

Fig. 1: Labelling of bushings Non-approved exchange of the hydraulic connections and components, or use of “non-B+V components“, will void any warranty for the correct functioning of the elevator and safety devices (closing signal).

1.4 Repair Any repair not performed by Blohm+Voss Oil Tools, should nevertheless be done in accordance with their methods and procedures or with their agents. All repairs should be done only by authorized and instructed personnel. Minor cracks or defects, which may be removed without reducing the safety or operation of the elevator, can be removed by grinding (see Fig. 2 critical areas).

After the repair, the parts should again be inspected by an appropriate method to ensure that the defect has been completely removed.

ATTENTION PLEASE ! IMPORTANT:

Remember to use only genuine B+V Replacement Parts and

Accessories. Otherwise, Blohm+Voss will not be responsible

for the proper operation of B+V Elevator.

The cylinders are installed in the hydraulic areas of the elevator in a protected way. 3.4 Closing signal unit When the bodies are completely closed and latched, the closing signal in the elevator is actuated.


12

4. Start-up 4.1 Installation of the elevator into the elevator links

Fig. 5: Link assembly Remove the cylinder bolts from the cylinder covers and cylinder bodies. Install the elevator into the elevator links. Make sure that cylinder connections, screws, castle nuts and cotter pins are assembled correctly.


13

4.2 Connecting the hydraulics to open and close the elevator The elevator has three connections on the rear (A, B and C).

Connection A: The hydraulic pressure at connection “A“ closes the elevator Connection B: The hydraulic pressure at connection “B“ opens the elevator Connection C: When the elevator is completely closed via connection “A”,

connection C applies an hydraulic pressure, depending on the pressure in "A".

Fig. 6: Hydraulic connections

Important:

Before connecting the hydraulic power equipment to the

elevator, clean all the couplings carefully !

4.3 Installing and removing the required bushing A bushing consists of two parts in the elevator bodies (see Fig. 1). The bodies and the latch must be open in order to equip the elevator with the required bushing. Make sure that both bushing segments are the same size and have the same serial number.

C B A


14

Important:

Before working on the bushings, make sure that no hydraulic

pressure exists on the elevator and that the connecting lines

are uncoupled !

The elevator must never be used without a bushing ! Removal of the bushing The screws on the top have to be removed. Screw handles into the bushing segments (see Fig. 7).

Fig. 7: Handling of bushings Installation of the bushing Before installing a new bushing, the seating area in the elevator must be cleaned and lubricated. Fix the segments with the screws on top of the elevator. Install the safety wire to secure the screws.


15

5. Service and Maintenance A regular preventive maintenance program should be established for all elevators. These written maintenance procedures should be given to the crew or maintenance personnel. Care should be taken that all warning labels are not missing, damaged or illegible.

Important:

For service and maintenance activities, make sure that no

hydraulic pressure exists on the elevator and that the

connecting lines are uncoupled !

5.1 Lubrication The elevator needs to be lubricated regularly on the following points.

Fig. 8: Grease points on the elevator Grease point 1: on top and bottom of the hinge pin (2 nipples each) 2: on top and bottom of the latch pin (2 nipples each) 3: lubricate springs daily 4: check and lubricate latch opening arrangement daily 5: on top of the retainer for plunger (1 nipple).


16

5.2 Functional test of the feedback signal The function of the feedback signal has to be checked daily. 5.3 Screw Securing All screws are normally secured by mechanical bolt lock or with a safety wire. All other screws are secured by metal adhesive (eg Loctite).

6. Inspection Every inspection should be done in accordance to API 8B. Before starting an inspection, remove all foreign materials (dirt, grease, oil, scale, etc.) from all surfaces. Field inspection of the elevator in an operating condition should be made by the crew or supervisor, daily! 6.1 Frequency of Inspection It is important to check the elevator daily and perform a semi-annual inspection. 6.2 Routine Daily Field Inspection Visual field inspection of the elevators in an operating condition should be made by the staff or the supervisor daily. Elevators should be daily visually inspected for cracks, elongation and other signs of wear, corrosion or overloading. If any elevator is found to show cracks, excessive wear, etc., remove the elevator/bushing from service. Procedure: Examine all elevators to determine whether the latch and the latchlock mechanism are functioning properly. Lubricate hinge pin, latch pin, latch lock and link contact surfaces every day. 6.3 Semi - Annual Field Inspection A thorough on the job shutdown inspection should be made on a periodic basis or as special circumstances may require. After a field inspection, it is advisable to record the extend of testing and testing results. Conduct the periodic semi - annual or critical load inspection in the field by the crew with the supervisor.


17

6.4 Critical Load Inspection Critical loads may be experienced, for example severe loads, impact loads such as jarring, pulling on stuck pipe, etc. If critical loads are unexpectedly encountered, conduct the inspection immediately after such an occurrence. 6.5 Dismantling Inspection Generally, when the equipment returns to base, warehouse, etc., carry out the elevator - inspection immediately. Furthermore, check it prior to it is being sent on the next job. The elevator/bushing should be dismantled and inspected in a suitably equipped workshop for excessive wear, cracks, flaws or deformations. Corrections should be made in accordance with recommendations which have to be obtained from Blohm+Voss Oil Tools Oil Tool Division. Welding of the castings should be done only by Blohm+Voss Oil Tools or an authorized service company. When need is shown in a field inspection, dismantle the elevator/bushing and arrange an inspection in a suitably equipped workshop. Inspect the 18° taper for uniformity and depth of wear.

Important:

Wear, uniform or uneven requires a change of bushing !

Hinge pins and springs should be carefully visually inspected for excessive wear and obvious weakness. 6.6 Measuring of wear It is obvious that a visual inspection cannot suffice for most elevator checks. To check the wear of the link ears (see Fig. 9 dimension A) it is necessary to use gauges and compare the results with the Table of Downrate Capacities (see Table 2).


18

Fig. 9: Thickness of top link ears 6.7 Use of Worn Elevators If significant wear is restricted to the top link ears, the elevator has to be downrated in accordance with the Table of Downrate Capacities (see below). sh tons DIM A (mm) CAPACITY (sh tons) 1000 ≤ 229,5 1000 ≤ 226,0 970 ≤ 222,6 950 ≤ 219,2 930 ≤ 216,9 910 ≤ 213,4 900 Table 2: Downrate Capacities The Elevator Bore or it’s bushing must be checked regularly with gauges. The gauges can be ordered from Blohm+Voss. Fig.10: Blohm+Voss 18° and 15° gauge (P/N 600018)
