Introduction
Thank you for choosing Sumner’s GH5T Gantry Lift
to meet your material lifting needs. The GH5T Gantry
Lift has a load capacity of 5 metric tons (10,000 kg) or
11,000 lbs. Following proper procedures for use and
maintenance of Sumner’s GH5T Gantry Lift described
in this manual will provide you with years of dependa-
ble service.
Gantry Components
Sumner’s GH5T Gantry Lift Consists of the below
components. Before attempting to assemble Gantry
Lift be certain that all components are available.
 2 A-Frames
 Cross Beam (4m, 5m, 12’ or 15’)
 Trolley
 Attaching Hardware (6 bolts, 6 nuts & 12 washers)
1. ALWAYS Inspect all equipment prior to use
to make certain it is in proper working order.
2. NEVER use unit If any part of equipment ap-
pears damaged or does not assemble properly.
3. ALWAYS use only Sumner replacement
parts. Any replacement parts not supplied by
Sumner Manufacturing will severely compromise
the quality and safety designed into this unit as
well as invalidate the warranty.
4. As a precaution, ALWAYS wear proper clothing
when operating unit, including hard hat, work
gloves and safety shoes.
5. ALWAYS avoid horseplay around equipment,
and keep bystanders at a safe distance. Do not
allow children to operate this unit and always
keep them out of work areas.
6. NEVER misuse the unit. Perform only the
functions for which the unit is designed. Never
attempt to operate the equipment at more than
the recommended capacity.
7. No riders on unit. This unit was designed for ma-
terial lifting purposes ONLY and is not designed
to function as a personnel lift or carrier.
8. NEVER stand under an elevated load.
9. NEVER exceed rated load capacity.
10. NEVER operate during high winds or electri-
cal storms.
11. NEVER use Gantry lift to support ladders or
other climbing devices.
12. When possible ALWAYS move loads by moving
the trolley on the Gantry cross beam while the lift
is stationary with all casters locked.
13. It is not recommended to move the Gantry lift
with a load. When moving the Gantry lift with a
load be sure to secure trolley in center of cross
beam to evenly distribute the weight across the
unit and lower load as close to the ground as
possible. Move lift by pushing the Gantry, not the
load.
14. NEVER leave a load on the Gantry lift unat-
tended.
15. ALWAYS adjust A-frame heights prior to attach-
ing a load and make certain cross beam is level
prior to attaching a load. See instructions in this
manual on how to adjust A-frame heights.
16. NEVER adjust A-frame heights without first se-
curing trolley to center of cross beam.
17. ALWAYS use Gantry lift on a hard, level,
smooth surface that is free of debris and obstruc-
tions. Be certain the surface the Gantry is on can
support the full weight of the intended load.
18. NEVER move a fully assembled Gantry lift
using a fork lift or other lifting device.
19. NEVER use Gantry lift as an electrical ground.
20. ALWAYS ensure load is not secured to the
ground before attempting to lift it.

2. Assemble Components
1. Lay out cross beam in a cleared area. Position
one A-Frame at either end of the cross beam as
shown.
2. Lift one side of cross beam onto A-frame saddle
and line up outside bolt hole on A-frame with the
outer most bolt hole on cross beam. Place bolt
through bolt hole on A-frame and cross beam
with washers on either side of the bolt. Loosely
tighten so A-frame/Cross Beam joint can swivel
when A-frame is erected.
3. Place trolley onto the opposite end of the cross
beam. Center trolley on cross beam and tighten
with set screws.
4. Lift opposite cross beam end and position onto
second A-frame saddle lining up outside bolt
hole on A-frame with outer most bolt hole on
cross beam.
5. Place bolt through bolt hole on A-frame and cross
beam with washers on either side of the bolt.
Loosely tighten so A-frame/Cross Beam joint can
swivel when A-frame is erected.
6. The supplied Chain Set and Hoist will be required
to erect the A-Frames.
7. Attach the end most hooks on the Chain Sets to
the eyelets on each A-Frame.
8. Attach the Hoist to the Spreader Plates on each
Chain Set.

9. Using the supplied Hoist, raise one of the A-Frames. It does not matter which side raises first.
10. Continue using hoist until either the Cross Beam is fully seated in the A-Frame Saddle or until the unit has
reached a position that allows for easy manual positioning of the A-Frame assembly as shown below.
11. When the Cross Beam is firmly seated in the A-
Frame Saddle, lock both casters by setting the
rolling brake.
12. Using a ladder, place two bolts through the A-
Frame and Cross Beam using washers on both
sides. Tighten all three bolts to that the connec-
tion is secure.
CAUTION
Be certain both casters A-Frame are
locked before erecng
13. Reposition hooks on the Chain Set to the inner
most hooks.
14. Using Hoist, raise second A-Frame and secure in
the same manner as described above.
