Safety
CAUTION: Practice safety in the operation and maintenance and use only approved
safety methods, materials and tools. Keep hands away from any pinch point or
undesignated areas; use only the provided handles for operating the elevator.
WARNING: Elevators which have experienced wear beyond established wear criteria set
by OEM, or are found to have cracks must be replaced or repaired by a BVM authorized
repair facility.
WARNING: Only original BVM parts may be used. Elevators are produced from cast
alloy heat treated steel and must not be welded in the field. Improper welding can cause
cracks and brittleness in heat-affected areas which can result in dramatic weakening of the
part and possible failure. Repairs involving welding and/or machining should be
performed only by a BVM authorized repair facility. Using an Elevator that has been
improperly welded or repaired is dangerous.
NOTE: The owner and user together with the manufacturer should jointly develop and
update inspection, maintenance, repair and remanufacture procedures consistent with
equipment application, loading, work environment, usage and other operational
conditions. These factors may change from time to time as a result of new technology,
equipment history, product improvements, new maintenance techniques and changes in
service conditions. Alternatively, BVM recommends using the Periodic inspection and
maintenance Categories and Frequencies as mentioned in API RP8B Table 1.

EN D 022 Rev D Page 2 of 12
Load test
WARNING: BVM elevators are load tested after manufacture or repair. Load testing is
mandatory on elevators which have not been load tested before. Load testing is required
on elevators which have been overloaded, for example jarring operations or operations
that have induced elevators to high accelerations or high impact loads. In addition, after
the load test, an annual inspection should be performed.

Description
The BVM “Y” Series center latch slip type elevators are used for handling a variety of small
casing (YC, MYC, & HYC) and tubing (LYT, MYT, YT, & HYT) with the proper size slips

EN D 022 Rev D Page 3 of 12
and slip setting ring installed. The slips are easily changed. The BVM elevator comes in sizes
ranging from 1.315” through 7-5/8”, with a capacity of 20, 40, 75, 125, 150, & 200 tons.
Elevators are made from alloy steel; load tested and are magnetic particle inspected.
CE Marking (if applicable):
Operation
The latch and safety latch lock of the Y elevators lock automatically when the elevator is closed
around the pipe by using the front handles. To open the elevator, simply pull the latch lock
handle out and swing the elevator halves apart. The load causes the slips to set when the
elevator is raised, pushing down on the slip setting ring. Proper inspection, operation, and
assembly are key to prevent dropped objects.
Installation:
1) Remove cotter pin and nut from link block bolt and remove link block bolt.
2) Lift the bottom of the link block and hook the small end to the link through the link
block and link arm.
3) Lower the link block and re-install the link block bolt, nut and cotter pin.
4) Repeat this procedure on the other link block.
5) To remove, simply reverse the installation process.
Warning:
•Ensure all slip inserts are free in the up position when latching the elevator.
•Elevators are manufactured to operate only in a vertical direction (within 15°) and
should NEVER be used for laying down on the ground for picking up pipe or tubing.
•The load rating of the elevator should never be exceeded. Both the static and dynamic
loads must be calculated to ensure safe working loads.
•Be sure to use the handles provided for opening and closing the elevator. Keep hands
away from all other areas when the elevator is in use.
•Check the latch and latch lock for full engagement when closed around the pipe.
•Make sure the Y elevators are used with the correct size, tubing or pipe (per
specifications). Oversized pipe could result in the elevator latching partially or not at all.
Undersized or oversized pipe could cause uneven stress distribution, inadequate load-
bearing area, and possible elevator failure or dropped tubulars.
•Elevators are made from cast alloy steel and should not be welded in the field. Improper
welding can cause cracks and brittleness in repaired area and can result in drastic
weakening of the Elevator and Parts and possible Failure.
•Repairs which involve welding and or machining by others that is not authorized by
BVM will void the warranty.
•Using an Elevator which has been improperly welded can result in serious bodily harm
and property damage.
•Never use the elevator other than what it is intended for: size and tonnage, which is
clearly marked on elevator.
•Use the ears for lifting the elevator, not the handles.

EN D 022 Rev D Page 4 of 12
•Only use the elevator within the specified temperature rating, which is -4°F to 150°F
unless otherwise specified.
Note: If an elevator is used despite the above warnings BVM voids all warranties.
Maintenance
Safety should be practiced at all times when servicing the equipment always use BVM
Corporation, approved safety methods, material and tools. Always wear protective gear for
eyes, head and hands.
1. Check for worn hinge pin, latch pin, latch lock pin, and their mating parts. These may
hinder proper opening and closing of door, latch and latch lock.
2. Check for proper operating of latch stop mechanism. Latch should not stop against the
body when engaged.
3. Open elevator and check hinge pin for wear by checking the radial play between the
body and door.
4. Check latch pin for wear by checking the radial play between the latch and body. Close
elevator and check that the latch and latch lock mechanisms function properly. Open
and close elevator several times, check for proper latch and latch lock function each
time. Check for proper operation of latch stop mechanism.
Caution:
•Do not use any elevator if the Latch and Latch lock do not function properly.
•Use only parts manufactured and sold by BVM Corporation
•Re-machining of parts should be performed only at BVM Corporation. Improper
machining could result in increased stress (Decreased Load carrying capability) or
improper alignment of component parts. Either condition could be hazardous to
personnel and equipment.
•Bodies and Doors should be matched by trained BVM personnel. For this reason, a
body or door from one elevator should never be exchanged with a body or door from
another elevator.
•Always wear gloves and eye protection when grinding, striking or handling parts.
•Do not use any elevator with wear in hinge pin, latch pin, and lock pin areas. Wear in
these areas will cause latch and latch lock to function improperly and may cause failure.
Lubrication
Lubricate the Elevator regularly during usage and storage to prevent corrosion. Use an extreme
pressure, multipurpose, lithium-based grease of No. 1 or No 2 consistency and multi-weight
motor oil.
1. Lubricate on a regular basis when in use.
2. Oil or grease hinge, latch and latch lock pin
3. Grease hinge and latch pin through grease nipples.
4. Grease underside of link arms.

Magnetic Particle Inspection (MPI)
Carry out MPI according to ASTM E709 or ASME BPVC sub section A, article 7 and
subsection B, article 25; determine the type of defects and the degree by comparing defects to
ASTM E125 reference photographs to the acceptance criteria.
Only cracks may develop and as such need to be reviewed. All other indication types have been
addressed by the manufacturer during production. As such, the elevator has left the factory with
indication (if at all) which were deemed acceptable. All cracks which have developed in service
are relevant and need to be examined.
Evaluation of indications:
Relevant indications: Only those indications with major dimensions greater than 1/16 Inch
(1.6mm) and associated with a surface rupture shall be considered relevant. Relevant indications
are indications that results from, discontinuities within the test part. Non relevant indications are
indications that results from excessive magnetizing current, structural design or permeability
variances within the test parts. Any indication believed to be non-relevant shall be regarded as
relevant and shall be re-examined to determine whether an actual defect exists. Linear
indications shall be considered as those having a length of more than three times the width.
Rounded indications shall be considered as those having a length less than three times the width.
A lined indication shall be considered as a group of three more indications which touch an
imaginary straight line connecting any two of the group.

Wear data
The inspection data and maximum wear tolerances are only valid if the equipment is in
otherwise good condition and has not been mis-used, does not exibit excessive wear, cracks or
other defects. Additionally any weld repairs – not done at a BVM authorized repair facility –
shall require examination and re-certification by a BVM authorized repair facility before being
used further. These data and tolerances only apply to certain critical components and cannot on
their own determine the overall condition of the equipment or its suitability for continued use.
These data and tolerances are what is required to retain 100% ratings.
