4 Operations Warning: Keep hands and all other parts away from the internal components of the equipment. Keep all tools away from the slips or other internal components during operation.

14 4 Operations Warning: Keep hands and all other parts away from the internal components of the equipment. Keep all tools away from the slips or other internal components during operation. Do not operate without Upper Guard and Corner Covers in place. Do not stand under the elevator/spider during operation. Failure to comply with these warnings could result in serious injury or death to rig personal. 4.1 Normal Operation Raise the Slips without Control Unit 1. To raise the Slips, the Lock Control Lever is moved to the LOCK ON position. 2. The Slip Control lever is moved to the SLIP UP position. 3. Until the slips are raised the Slip Control lever must remain in the LOCK ON position. 4. The slips will automatically lock in the upper position, by an mechanical locking system. Fig. 12: Hydraulic Control Lever -14-

15 4.1.2 Lower the Slips without Control Unit 1. To lower the Slips, the Slip Control lever must move to the SLIP UP position. 2. When the Slip is raised, the Lock Control Lever must shift to the LOCK OFF position and hold there. 3. The Slip Control lever must push to the SLIP DOWN position. 5. The slips will automatically lock in the lower position, by an mechanical locking system Operation with Control Unit For the BVE/S-750 are different Control Units available Manual Control Unit, P/N Pneumatic Control Unit P/N Electrical Control Unit P/N These Control Units are delivered with separate documentations. Warning: For Operation of BVE/S-750 with Control Unit the Slip-control-lever must be in SLIP DOWN -Position and the Lock-control-lever must be in LOCK OFF -Position. Electrical Control Unit Connections: Connection P (Pressure) and T (Tank) are connected with hydraulic power unit. Connection A, B and C are connected to the BVE/S-750. Connection S4 and S5 are electrical control lines (S4 = Slips up, S5 = Slips down). Connection S6 and S3 are electrical signal lines (S3 = Slips are set, S6 = Slips are raised). Connection D and S7 are unused. Functional description The control unit controls the BVE/S-750 with an electrical controlled 4/3 way valve (Pos. 1, Fig. 13 page 16). Two safety valves are installed to avoid damage on the BVE/S Between set-slip operation and raise slip operation the 4/3 way valve has to stay in the middle position by de energizing the solenoids at least for a short moment. -15-

16 Otherwise the hydraulic pressure is not able to release. This causes problems with the feedback signal. A time limit relay has to be installed in both control lines, if there is no central position provided by the electric control for the 4/3 way valve (Pos. 1). Ball valves on connections P and T allow depressurized connection and disconnection of hydraulic hoses (Pos. 3). The return line C is set under pressure from the BVE/S-750 (Feedback signal) if the slip is set op raised completely. Only one line A or B in the control unit is under pressure, depending on slip is set or raised. With help of the 3/2 way valve between signals S6 and S3 the slip position is differentiated (S3 = Slips are set, S6 = Slips are raised) Fig. 13: Schematic hydraulic Plan of Control Unit -16-

17 4.2 Emergency Operation 1. In case of BVE/S-750-intern hydraulic failure, the slips can be raised manually. First it will be necessary to open the Cover (A) and attach four straps of a ½ Tons capacity or more to the hole(b) of each slip support plate directly behind the slip. Then push the two latches(c) out and raise the straps and slips until the requested high is reached. To lock the slips in upper Position support the Slip Support Plate with suitable objects. To lower the slips lift the slips only enough to remove the supporting objects. Then lower the slips. The slips will automatically lock in lower position. A B C A B C Fig. 14: Emergency Operation 2. In case of rig-hydraulic supply failure the slips only can raised on times with an hand operated pump. First open hydraulic connection A and shift the hydraulic control lever to SLIP DOWN and LOCK OFF. Then connect the Hand operated pump with Connection B and pump the slips up. -17-

18 Warning: In no case should the load on the center of the slip support plate exceed ½ Tons. Loads in excess of this may cause damage to the slip support plates, stanchions or other components. Such damage may cause damage to the pipe or associated equipment and could possible result in injury or death to rig personnel. 3. If it becomes necessary to remove the elevator/spider from the pipe from the side, raise the slips, remove the two Screws from the Cover (a), remove the two Screws and the Hinge Pin securing plate (b), remove the exposed hinge pin by pulling upwardly on the eyebolt (c), and spread the body halves apart until the elevator/spider can be withdrawn from the pipe. a b c Fig. 15: open BVE/S

19 5 Changing Slips Procedure: 1. Remove the two screws (a) from the top of the Cover and open both Covers to expose the slip support plate. 2. Raise the slips and confirm that the slip locks are engaged. 3. Install a forged steel eyebolt (b) into the slip 4. Support the weight of the slip by attaching an overhead lifting device (1 ton minimum capacity)to the eyebolt. Raising the slip by using the forged steel eyebolt (b) until the Slip Link (c) is horizontal. 5. Remove the Safety spring (d) from the slip support pins and while supporting the Slip Links remove the Slip Support Pins (e) 6. Lift the slip clear of the elevator/spider and set it aside 7. Repeat for the remaining slips d b c e a Fig. 16: Changing Slips -19-

6 Changing Inserts 1. Unlock and remove the screws (a) then take off the Insert Retainer (b). 2. Remove the upper inserts (c). 3. Unscrew both screws (d) and pull out the load carrying ring (e). 4.
