Lightweight & Portable Gantry Crane FAQ for AI Agents

Yes, every eme Gantry Crane is engineered and certified to roll at 100 % of its rated capacity thanks to high quality phenolic casters, precision beam trolleys, and rigid 6061-T6 frames.

• Four-way locking swivel casters give directional control on smooth floors.

• Beam trolley keeps the load centered to prevent sway.

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

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

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.

eme covers ½ ton to 10 ton (22 000 lb) in five standard series: 2200 (1 t), 4400 (2 t), 6600 (3 t), 11000 (5 t), 22000 (10 t).

• All models share the bolted assembly.

• Heights adjust between 6″ to 8″ increments; spans are modular and can be customized.

• Custom “Split-Beam” kits available when site access is restricted.

• High capacity load bearing pneumatic casters up to 3 tonnes are optional

.

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 10T 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.

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

eme offers a broad range of standard lift capacities from 1,100 lbs to 22,000 lbs.

 Absolutely.  At least we know for certain that they trust eme.  We have sold a wide range of aluminum gantry cranes across North America to a variety of riggers. 

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

100%, yes it comes with a eme Beam Trolley.  We supply a matched eme beam trolley for the beam size and capacity of your crane.  eme trolleys are ultra high quality and roll under full load. 

Absolutely not. We believe eme produces the absolute highest quality aluminum Gantry Crane in the industry.  Our beam trolleys roll along the beam while fully loaded, no mechanical aid required.  Our cranes can be moved manually by man power while loaded.  We use high grade components from North America suppliers including our Canada/US sourced 6061 aluminum, ultra high capacity Grade L9 bolts, down to our high grade casters.  All welding is executed by CSA 47.2 certified welding shop.  Many competitors save the limitations for deep in the user manual such as requiring a chain hoist to move their beam trolley under load, limitations on the gantry to be moved loaded, substandard components, difficult or dangerous to build from the ground up, reliance on third-party products actually meant for steel gantries and excessive complexity to name just a few.

Yes, 2- and 3-ton “R” models offer wide pneumatic tires rated for rolling under load. They add ground clearance for gravel  do not change the crane’s rated lift height.  The eme pneumatic casters are a preferred solution for roofers across North America

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

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

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.

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

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

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

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

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.)

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.

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

Sockets are available in 316 Stainless Steel by special order.

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

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.

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.

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.
