1.0 Introduction
Keystone ENERGY TOOLS
This manual contains operation and maintenance
instructions for the Keystone Energy Tools (KET) MGG
series, bottleneck and center latch elevators for
handling 18 degree external upset drill pipe with
assembly drawings and complete parts breakdown. It
provides a guide for proper field use, disassembling
and repair.
(KET) MGG series elevators are designed to fit the
contour of 18 degree type drill pipe. They are balanced
making them easy to handle as well as easy to latch
on or take off at any point below the upset of the pipe.
MGG series elevators are made of high alloy-heat
treated steel and designed to meet or exceed API
specifications.
The MGG elevator is only intended for lifting of
veridical pipe and not intended for use on horizontal
pipe. (See diagram on page 3). Lifting of horizontal
pipe is NOT PERMITTED by the manufacturer.
If the operator considerer to use the elevator for other
operations other than the intended use (for example:
lifting of horizontal pipe), it is mandatory to make an
additional risk analysis.
The MGG series elevators include safety features such
as guarded operating handles to help prevent injury to
operators and an extra handle at the rear of the
elevator for easier, safer operation.
⚠WARINING: These handles are the only places
the tool can be handled safely during operations.
The MGG series elevators incorporate a latch land
safety latch lock combination. The size range of the
MGG elevator is as illustrated in the table
provided.(See Figure 1)

NOTE ⚠WARINING labels have been installed at
critical areas on the tool. Familiarize yourself with their
message and locations before proceeding to operate
equipment.
See Safety Instructions Page 4
CE Marking
The tool complies with the Machinery Directive
98/37/EC and 2006/42/EC
This operating manual is a part of the technical
documentation for the product.
The EC Declaration of Conformity is delivered
together with the product. Keep these instructions and
the associated documents for later use.

2.0 Operation
Keystone ENERGY TOOLS
As with any manual operated elevator, the MGG series
is easily installed by the user. Perform the actions
described below after the elevator is hoisted to the rig
floor and properly positioned.
•Remove cotter pins and nuts from the link block
bolts and then remove the bolts from the elevator.
•Lift the bottom of the link blocks and hook the small
end of the links through the link blocks and link
arms. (See figure 3)
•Lower the link blocks and re-install the link block
bolts, nuts and cotter pins.
The operation of the MGG series elevator is
straightforward.
The door is opened by gripping the latch lock and pulling
outward. This automatically releases the latch and latch
lock assembly so the elevator can be positioned on the
pipe. When the elevator is properly closed around the
pipe, the latch locks automatically.
(See Figure 4 & 5)

When installing the upper and lower link block bolt, castle nut, and cotter pin, the bolts must be
inserted from the front of the elevator so that the head of the bolt is on the latching side of the elevator,
and the castle nut and cotter are on the hinge side of the elevator.
See the illustration below, showing the correct and incorrect method of installing the upper and lower
link block bolts on the IB-G Series Elevators.
⚠WARINING : Failure to follow these installation requirements can cause severe bodily injury and/or
death.

3.0 Maintenance & Inspection
Keystone ENERGY TOOLS
To ensure optimum performance, perform the below-listed daily checks.
•Visually inspects for cracks, loose fits or connections, elongation of parts, and other signs of wear,
corrosion or overloading.
•Loose or missing components, deterioration, proper lubrication, and adjustment.
•Check for worn hinge pin, latch pin and latch lock pin. These may inhibit proper closing of the door and
latch lock engagement.
•Check for proper operation of Latch Stop mechanism. Latch should not stop against the door when closed
but have no more than ¼” of standoff from the door. Check springs for damage, deformation, and lack of
tension.
•Check link block bolts for nuts and cotter pins.
Below is a diagram of each elevator maintenance location located on the MGG elevator. See
figure 5.

3.0 Maintenance & Inspection
Keystone ENERGY TOOLS
The owner/user of the equipment should develop schedules of inspection based upon experience,
manufactures recommendations, and one or more of the following factors:
Environment
Load Cycles
Regulatory requirements
Operating time
Testing
Repairs
Remanufacture
Proof Load Test shall be performed only once following manufacture or remanufacture. This is by applying
a load equal to 1.5 times the rated load for a period no less than 5 min. A proof load test shall be followed
by surface NDT no earlier than 24 hrs. after proof of testing.
Lubricate the elevator regularly during usage and storage to prevent corrosion. Use an extreme pressure, multi-
purpose, lithium base grease of No. 1 or No. 2 consistency or a lubricant that meets MIL-SPEC-A907E.
***When greasing of pins make sure the pump grease until it comes out of both ends.***

4.0 Repair
Keystone ENERGY TOOLS
The MGG series elevators incorporate lock bars to retain the hinge & latch pins. All latch springs operate off the
spring stop pin.
DISASSEMBLY PROCEDURE
•Remove the latch lock assembly and latch spring by driving or pressing out the lock bar and driving out the
latch pin from the bottom of the elevator.
•Remove the latch lock from the latch by removing the Teflon nut and drive or press out the bolt.
•Remove the hinge pin by driving it out from the bottom of the elevator, shearing the lock bar in the process and
remove the latch pin in the same manner. As an alternative method, the lock bar can be drilled in the center,
then split by using a chisel and removed. In either case the lock bar must be discarded.
•If either link block is to be replaced, remove the link block bolt and cotter pins.
•If the door lug pin is damaged, drive or press it out from the bottom of the lug.
•Reassemble by reversing the above steps.
•Install new lock bars on hinge and latch pins.
•After assembly, ensure that full spring tension is available to close the latch & lock. The latch spring should
contact the spring stop pin which in turn transmits the spring force to the latch.
•Check the latch for proper engagement with the door lug pin by holding the body and door apart (such that the
latch contacts the lug on the door) and attempt to pry the latch open. After minimal of the latch the hook on the
latch should engage with the door lug pin stopping the travel of the latch.
•Check link block bolts, nuts, and cotter pins.
