FAQs

Quick answers to the common questions asked about our products.

gantry cranes

Can the eme Gantry Crane be moved while under load?

Yes, every eme Gantry Crane can be moved while under its full-rated lifting capacity.

Can I make customizations to the eme Gantry Crane?

Yes, the way we manufacture the eme Gantry Crane makes it highly customizable. Here are a few of the many customizations available:

  • Lift range
  • Lift capacity
  • Leg adjustment interval
  • Beam width adjustment interval
  • Castor type
Can you adjust both the beam clear span and beam height?

Yes, the beam clear span and beam height are adjustable on all eme Gantry Cranes.

How long does it take to setup an eme Gantry Crane?

For our standard models under 5T, it typically takes to 2 operators ~5 minutes to set up. For our higher capacity models and higher lift height models it takes approximately 15 minutes to set up. We offer an optional come-along system for our taller and higher capacity models.

Will my aluminum eme Gantry Crane get damaged if I need to ship it to different locations?
The eme Gantry Crane is extremely sturdy. However, for customers that ship frequently, we created our custom steel shipping pallet. Unlike wood pallets that become damaged quickly, the eme Steel Shipping Pallet perfectly secures the eme Gantry Crane and can be reused over and over.
Is the eme Gantry Crane tested before it is shipped to me?

Yes, every single eme Gantry Crane is Proof Loaded and tested prior to shipment at or above OSHA requirements. eme Gantry Cranes between 1/2T to 5T are Proof Loaded to 150% of Rated Lifting Capacity. Our 7.5T and 10-ton Gantry Cranes are Proof Loaded to 125% of Rated Lifting Capacity. You will receive a Certificate of Test with the serial number of your eme Gantry Crane certifying that it had been tested prior to shipment. Safety is a high priority for us at eme.

Do I get engineers stamped drawings with my eme Gantry Crane?

Yes.  We include Engineers Stamped Drawings that cover the design of your crane with each crane shipped.

What is the standard lifting capacity of eme Gantry Cranes?

eme offers a broad range of standard lift capacities from 1,100 lbs to 20,000 lbs.

How is the maximum working clear span determined for an eme Gantry Beam?

The maximum working clear span is 3 feet less than the length of the eme Gantry Beam.

What type of capacity chain hoists can be used with eme Gantry Cranes?
Manual or electric chain hoists can be used with eme Gantry Cranes. The chain hoist must not have a higher rated lifting capacity that the eme Gantry Crane with which it is being used.

davit cranes

Do I receive any engineering or safety documentation with my eme Davit Crane?
Yes. There is an engineer-stamped drawing and Certificate of Test supplied with every piece of eme‘s equipment. All eme Davit Cranes are made of aircraft-quality aluminum. All Davit Cranes are tested to 150% of Rated Capacity prior to shipment from our manufacturing facility.
What is an eme GEN II Davit Crane?
In 2011, we redesigned our Davit Crane, making it lighter for greater ease of use. This includes both the 1100 and 2200 Series.
What are the assembled weights of eme's GEN II Davit Cranes (Chain Hoist Model)?

The assembled weights are:

  • Gen II 1100CH – 38 lbs.
  • Gen II 2200CH – 45 lbs.
  • Gen II 1100W – 65 lbs. (includes winch, cable, hook)
  • Gen II 2200W – 68 lbs.
  • 3300CH – Variable
Is the winch removed after use of the winch models?

No, the winch stays permanently attached to the eme GEN II Davit Crane.

Do the eme GEN II 1100CH and eme GEN II 2200CH Davit Cranes with the chain hoist break down into smaller pieces?

These models fold up into a compact package, with no disassembly required. The 3300CHCU (not a GEN II), due to its weight, is designed to have the arm detach from the Davit top.

Does the eme GEN II 1100W Davit Crane break down into two pieces?

No, the eme GEN II 1100W Davit Crane does not break down. The Davit arm remains attached to the Davit top.

What are the minimum assembled lifting heights of the eme GEN II 1100CH and eme GEN II 1100W Davits?

The minimum assembled lifting height is 80 in/2.02 m for both.

Why are the dimensions for the lifting height under the chain hoist approximate?

The dimensions are approximate because different models of chain hoists have different hook to hook dimensions.

How can I increase the lifting height of the eme GEN II Davit Cranes?

Use a Custom Top Mount Socket (up to 60 in./1.52 m in height) or increase the length of the Davit Crane Arm.

What type of chain Hoists can be used with the eme GEN II Davit Cranes?

Electric or manual chain hoists can be used with all of the eme GEN II Davit Cranes. Hoists must not have a rating greater than the rating of the Davit Cranes – (1,100 lbs./500 kg. to 2,200 lbs./1,000 kg.)

Why would a Variable Radius Arm (VRA) be used?

A VRA would be used with an existing eme GEN II Davit Crane to lift UV light arrays for easy maintenance of this critical disinfecting equipment. It has the range of physical coverage of a costly overhead bridge crane, but with a cost of less than 30 percent of this piece of equipment.

sockets

What types of Sockets are available from eme?
  1. Flush Mount (cast-in-place – new construction)
  2. Flush Mount (cored hole – locked in place with resin)
  3. Top Mount – 8 in. to 42 in.
  4. Side Mount – Flush to 42 in.
  5. Heights can be customized
Does eme supply Stainless Steel Sockets?

Sockets are available in 316 Stainless Steel by special order.

Are caps available for the Sockets?

Yes, Top Mount Socket, Side Mount Socket and Flush Mount Socket caps are included for all sockets.

What is the best location for a Socket?

eme Sockets can be placed as close as two inches from the edge of a tank or wet well, using a Top (end) Mount Socket. Side Mount Sockets and Flush Mount Sockets are also available. eme recommends that customers consult a professional engineer or another qualified professional for direction when installing Sockets.

Does eme install Sockets?

No, eme does not install Sockets. It is the responsibility of the customer to arrange for installation. We suggest that customers:

  1. Obtain a site plan from a qualified person (i.e., a professional engineer) for the location in which they expect to install the Sockets.
  2. Have a qualified person or company install the Sockets.
  3. Use eme-recommended anchors, adhesives, etc. that will handle the loads and forces imposed on the Socket(s) by the eme Davit Cranes.
Should a drain be provided for Top Mount or Flush Mount Sockets?

If possible, a drain line should be installed to remove water or moisture that may collect at the bottom of the Socket tube. The individual doing the site plan should determine whether a drain line can be installed. All eme Sockets are provided with a drain hole at the bottom of the Socket tube.
