Ideal for almost any industrial setting or heavy duty operation where strength, safety, and movability are required. Compared to a heavy steel gantry crane, which is awkward and difficult to move; an eme mobile gantry crane is light, easy to assemble, and portable. Due to the lightness and portability, these cranes can be used for many jobs in several different locations. All eme 3 ton gantry cranes and 5 ton gantry cranes can be taken down and reassembled with just two people in less than 15 minutes, which allow for quick movement of the crane within a single building, or transporting via a pickup truck to other locations.

Standard Gantry Features and Models

Ground-Up eme Gantry Crane Assembly
eme Gantry Crane Assembly Step 1 eme Gantry Crane Assembly Step 2 eme Gantry Crane Assembly Step 3
Step 1
  • Remove bolts from top two holes in Cheek Plates. Loosen nuts but do not remove bottom nuts/bolts on Cheek Plates.
  • Lay both Gantry Legs face down with the Slant Strut on the ground.
  • Grasping the Beam Handle, lift the Beam up and slide between the Cheek Plates.
  • Line up the rear hole in the Beam with the Top Hole in the Cheek Plates.
  • Slide the 5/8x5-1/2 in. bolt through the Cheek Plates and Beam.
  • Install the washers and nuts on the bolt.
Step 2
  • Pull first leg up into position as shown in photo
  • Line the front hole in the Cheek Plates with the 3rd. hole in the Beam
  • Slide the second 5/8x5-1/2 in. Bolt through the Cheek Plates and Beam
  • Install the washers and nut on the bolt.
  • Tighten all four Bolt-Nut assemblies so the Cheek Plates firmly grip the Beam.
Step 3
  • Install Beam Trolley on Beam. Move Trolley up the Beam and Lock to Beam.
  • Repeat Step 1. Raise Beam and place Beam between Cheek Plates.
  • Line up rear hole in Beam with Top Hole in Cheek Plates.
  • Slide 5/8x5-1/2 in. bolt through Cheek Plates and Beam.
  • Install washers and Nut on bolt.

Step 4
  • Repeat Step 2. Pull second leg into position so Cheek Plates line up with 3rd hole in the Beam.
  • Install 5/8x5-1/2 in. bolt through Cheek Plates and Beam.
  • Tighten Bolt-Nut assemblies as in Step 1.
Step 5
  • Assembled Gantry Crane should look like unit in photo.
  • Unlock casters to roll Gantry. Use swivel locks to lock casters to steer Gantry.
  • Before Assembly or Knockdown of Gantry, lock casters at 90 degrees to the Beam (see Photo).
  • Lock Casters for swivel and roll when lifting or lowering loads.
Clear-Span Adjustment (Setting Clear-Span on the Ground)

Normally the gantry legs are attached at the end of the beam. This provides the greatest Clear-Span (distance the Beam Trolley can roll on the beam between the Cheek Plates).

On occasion the lifting application may need to reduce the space between the legs due to reduced floor space. It will be necessary to set the legs in from the ends of the beam so the beam sticks out past ore or both legs. The following method allows the gantry to be assembled in the standard way of assembling the gantry crane (see above for assembly method).

Gantry Crane Clear Span Adjustment Example

Place the legs with the Slant Struts on the ground. Raise the leg up and place a piece of 2x4 under the Cheek Plates. Calculate how far down the beam the Leg must be set to accommodate the reduced floor space (the holes in the Beam are spaced 8" apart and the Cheek Plates cover 3 holes). The photo shows the Cheek Plates lined up with the 4th. Hole from the end of the beam. This has reduced the Clear Span by 24" (3x8") and has moved the leg in 24". If this is done at the other end of the beam then the Clear Span will have been reduced a total of 48" and moved the legs in 48" in total. On a 15 ft. Beam this will mean the Clear Span has been reduced from 12 ft. (the Cheek Plates are each 18" long for a total of 36" or 3'). The clear span will now be 8 ft. (12'-4' = 8'). The Casters will now be 8 ft. apart and the Beam will stick out past the legs by 24 in. on each end.

Any of the holes in the Beam can be chosen but there must be 2 more holes in the Beam so the Cheek Plates can be fastened to the Beam.

Once the Cheek Plates have been fastened to the Beam at each end the Gantry can be assembled in the normal fashion (see above).

Photo on the right shows Beam propped up on a tall support. This is an exaggeration to show the leg and Beam off the ground.
