Note: Due to the camera lens curvature, in some of the photos shown below the legs or I-beams may not appear straight. Also, several of the pictures were taken during the testing stages and therefore do NOT have all the required safety labeling. Labeling is/was done prior to shipping. All custom gantries have load tests prior to shipping standard. Shown below in several of the pictures are just a few. We load tested to a minimum of 127% of rated capacity.
The crane above is in a nuclear facility in the Carolinas. Rated cap. 6,000 lbs. and is 15′ under the beam. It also has the ability to have a 2′ cantilever from the legs at the wall end. (Note the adjustable legs)
This custom All-Terrain gantry with crank down jacks is in use at a submarine base located in the north east United States. Not much to tell here, as sub bases are pretty hush hush in describing there uses of equipment.
Seen above and below, this custom 4,000 lb. cap portable gantry crane with attached 4K Thern electric cable winch was designed to meet our customer’s requirements. Due to head room restraints and machinery height, there was no room to under attach a pulley system. Therefore we designed a two part I-beam assembly (shown in the lowest picture), thus allowing us to mount the pulleys inside the I-beams, gaining us the needed headroom. The load would always be picked from the center of the beam, so no lateral movement was required. This aluminum gantry is being used to maintain and repair 25 + robotic machines in Kentucky. (Note: In the lower picture what you see a snatch block. The lifting cable is actually running between the two part I-beam where the pulleys are attached.)
This customer is a large rigging firm located in several U.S. states. They required several custom 8,000 lb. cap. 12′ HUB T-Frame gantries. Note: The flex you see in the upright column created no permanent deformation to the column and was well below the yield and tensile strengths. Aluminum has a large amount of elasticity to it, unlike steel which would have stayed bent. In case you’re wondering, the test load you see here was in excess of 10,000 lbs. Also note that the load is clear to one side and the caster positioned in the worst possible direction.
A special testing platform was built for this custom 3,000 lb. cap. 14′ under beam A-Frame gantry. It needed to ride on two different levels, beyond the limits of min and max adjustments. The far leg has fixed casters only, NOT swivels which allowed us to be able test this gantry in this method. This aluminum gantry is in use at a nuclear facility outside of Chicago, IL. They also purchased another full length upright column and base so that the gantry could be used as a standard 14′ HUB 3,000 lb. cap. gantry. It also required a load test.
Our customer’s requirements were met with this unusual aluminum gantry crane design. Requiring a TOB Max 118″ in height but also required a min. 73″ TOB, do to obstructions in their room. Our design gave this crane 45″ height adjustability. 99% of the small portable aluminum cranes on the market today do not have more than 30″ of adjustment. Now why the jacks? It was set forth by the safety personnel at Intel, that no one employee can lift more than 35 pounds at their facility. In order to raise and lower the gantry heights, it would have been more than the 35 lb. max lift due to the weight of the hoist and trolley. Hoist and trolley had to be attached to the gantry before height adjustment (something do with using ladders at their facility) and could not be removed from the I-beam. (We noted that moving the trolley/hoist from side to side during raising would alleviate that, but that did not matter to safety. No, two employees can share a lift per safety personnel) At the customer’s request, we incorporated jacks they supplied, to make height adjustments.
This particular model gantry was designed specifically for Caterpillar Marine for use in repairing their marine engines in larger cabin cruisers. It is a custom removable leg gantry with rubber foot pads as not to damage the fiberglass hulls. 1″ hole spacings were used on the legs to give it greater adjustability, thus keeping the gantry level during use. The compact design enables them to position it in the confined spaces of the cruisers engine compartments.
Above and below Toshiba Corp. contacted us to design and manufacture 10 custom gantry cranes (shown above and below on the catwalk) to install and maintain pumping equipment for a new hydroelectric dam in Michigan. A Toshiba representative flew out to our manufacturing facility in Elko, NV to verify the following: 1. Retain copies of all aluminum certifications used in the construction of each gantry. 2. Visual conformation of our aluminum tracking methods and handling procedures. 3. Obtain letters of conformance from all vendors that were used in providing components used in manufacturing (casters), hardware (nuts & bolts) etc. even down to the welding wire. 3. Visually verify numerous welds (watching our welders weld) and verify that the welds corresponded to our welding procedures. 4. Obtain welders certifications. 5. Visually verify load testing.
This little crane was built to our customer’s specifications
Photos above and below is a gantry designed for nuclear facility used to remove cooling tower impeller. This crane has three main vertical legs indicated by the blue arrows. It needed to be able to be broken down in order to be assembled in the confined space shown above and below. 8,000 lb. cap. and 12’5″ under the beam height was required.
This A2P1010 Removable Leg gantry is completely hard anodized with stainless steel particulate casters for a clean room environment. Ontario, CN
This 15′ long I-beam, 2,000 lb. cap. gantry crane was made for assembling over a working 1/2 mile long conveyor system (That could NOT be shut down). The suspended leg was slide out on custom made UHMD glides over the moving conveyor, and then lowered into position. At that point the middle was removed so as to have a working gantry crane. Ontario, CN.
This custom 3,000 lb. cap. gantry crane was designed for a nuclear power station in Illinois to change/service impellers and pumps. The use of All-Terrain style bases were used do to the uneven floor because of numerous floor drains.
This customer, Tomo Therapy, has multiple gantry cranes designed and manufactured by us for their service department. The crane attaches directly to their radiation therapy machine, but also has a wheel kit for a standard rolling crane. They manufacture a line of cancer therapy units and ship the gantries worldwide for the servicing of their machines. Madison, WI
Following our customer’s request, we designed and engineered this gantry crane so it could be rolled through an 84″ door fully assembled in the lowest position. They also needed the ability to reach 11′ under the beam in the highest position, with specific hole positioning in between. This customer also requested bolt on extension spacers Albuquerque, NM.
This air tire gantry cane was used in a 24 acre solar farm in Gila Bend, Arizona. This customer purchased three cranes to set solar panels.
We designed and engineered this aluminum gantry for Shell Oil for fuel efficiency car testing. Although rated for 1,000 lb. the load applied to the rope pulley was only 150 lb. The customer wanted the ability to “immediately” release the load. We incorporated the use of a Harken sailing 3 shiv mechanical advantage rope pulley. It was adjustable in height as well as having folding legs making it portable to ship it throughout the world.
Notice the yellow bottle jack. This aluminum gantry crane was designed to be raised and lowered while fully loaded (8,000 lb. cap). The jack platform (not well seen) was able to be pinned in different positions up and down. This gave the jacks the ability to be raised/lowered thus being able to raise and lower the column/I-beam to the next hole spacing. As you can imagine there was no room for a hoist to lift the head off the motors block. The head was shackled directly. Los Angeles, Ca
This 15′ long I-beam was too long to fit into the elevator. We designed the beam so it could be cut and bolted back together.
This 4,000 lb. cap. Aluminum Twin I-beam Gantry Crane was designed to have the main cross be set and an angle. The top caps were welded directly to each end of the main I-beam. It will be used straddle chiller motors at one of the newest resorts in the Bahamas. In order to remove the motors they will have to be under slug from both sides do to headroom constraints. The ability to move (space) both twin I-beams made sure it will not take any side work loading. We also supplied them with four Coffing hoists and trolleys. Custom slings will have to be made as well.
This model was developed for Siemens Medical Group. These cranes are stationed thought out the entire world in cancer treatment facilities!
We were load testing the crane above so it was not completed when the picture was taken. This crane was constructed of 1/8″ 6061 aluminum with a 2,000 lb. cap. It was designed to be setup and removed by hand from a platform 45 feet above an elevator shaft in New York.
A custom 500 lb. cap. work station crane that had an I-beam so a trolley could be used. It also has a foot brake pad.
Above and below are pictures of a gantry designed and built by us to hold ground lighting. (Installed by customer.) It had a 300 lb. load capacity and is used to grow grass at an indoor stadium. It needed to be adjustable in height to pass through a standard height door. Large width and diameter tires were used so it would not leave a foot print on the grass. It also had a trailer hitch attachment to be pulled by a garden tractor.
The above picture shows an A-Frame gantry crane that was completely constructed of 316L Stainless Steel, casters included with exception of 17-4 PH I-beam clamp bolts. Custom 316 SS beam clamps were also fabricated for the gantry. It had a 4,000 lb. cap. and was built for a pharmaceutical facility in New York.
We designed this particular aluminum gantry for outdoor use only. It was originally going to be constructed of 6063 but was changed to 6061 at the customer’s request do to time and cost constraints. They are setting this crane on a roof of a building and “never” moving it. Located in Seattle, WA. where the elements could affect any bolted joints with corrosion. We designed it with extra long top caps thus doing away with any hardware.
The above custom gantry crane was manufactured for a nuclear power plant in New Hampshire. Note the dual I-beam design that was specifically engineered for their application. The main load beam attached to a wall thus eliminating the need for lateral bracing.
This 1,000 lb. cap. custom gantry crane was designed for a company that manufactures plastic medical implants. The gantry was to be setup in a semi clean room environment. It has a 316 stainless hand crank wench and cable. After initial testing shown above, the crane was sent off and completely hard anodized.
This custom aluminum gantry crane was designed for a nuclear power plant in Alabama. They needed remove an 8,000 lb. steel plug in the floor for room modifications. Because of non-movable electrical panels attached to the walls, the crane was made with angled legs to clear the panels when moving it.
This 1,000 lb. cap. gantry crane was custom manufactured for a customer in Canada that needed to roll the crane while loaded on multiple floor heights at once. As with ALL of our All-Terrain style gantries, to ensure that the cranes stays level we attached bulls-eye levels to the bases and horizontal levels to both sides of the I-beam.
This custom gantry was designed and manufactured for University of Davis, CA Veterinary Dept. This rolling style bridge crane is being used to support and position surface compression testing equipment.
Above is our 14′ under beam 4,000 lb. cap. A-Frame gantry. It has a custom 20′ long I-beam split at 12′ and 8′ sections. It was not possible to move the full length 20′ long I-beam to the gantry setup location without cutting down the I-beam into two sections
