Portable Jib Cranes

Air Technical Industries announces the development of a new series of Portable Jib Cranes that are self-supportive and can be used anytime, any place, indoors or outdoors, without installation. The Portable Jib Crane has a counterweight built in to the base for stability and fork pockets for portability.

Portable Jib Crane

When the job is done, the crane can be easily moved out of the way, since it is not bolted to the concrete floor, as it is in the case with traditional jib cranes. The ordinary jib crane can only be used at one fixed location and is limited in flexibility that the new portable crane offers.

One crane that can be used at many locations adds great versatility and savings by not needing many cranes at different locations, and it also saves space on the shop floor. The Portable Jib Crane is also convertible and can be detached from the base and mounted to the floor.

The crane features a 360° boom rotation manually operated and there is an optional powered boom rotation available. The crane can be equipped with a manual hoist or electrical powered hoist, 110 volt single phase or 240-480 volts, 3 phase. For hazardous areas, air powered pneumatic spark proof hoists are available.

Portable Jib Cranes are built of heavy duty industrial welded steel construction for safe and long lasting use. The rotation is on a heavy duty Timken roller bearing and precision built cam followers for smooth, easy, effortless rotation. Cranes are available in capacities of 500, 1000 or 2000 pounds with a span length of 6 to 12 feet and an under beam height of up to 24 ft.

The cranes feature 2 different counter balance designs, one is counterweight built into the enlarged base for stability and the other is mounted on the rotating beam so that counterweight is always on the opposite side of the payload. The specially designed counterweight base has 4-way fork pockets for easy accessibility from any side.

The Portable Jib Crane is an ideal tool for on the spot lifting and handling of heavy components at different locations. It can be a great complement to a larger overhead crane to save the time for heavier lifts, while using the Portable Jib Crane under the overhead crane to help out.

Earthquake-Proof Seismic Crane

[March 28, 2012] Mentor, Ohio – Air Technical Industries announces the manufacturing of the unique telescopic mast articulating crane, constructed mostly from aluminum.

Aluminum Telescopic Mast Jib Crane for nuclear plant

The crane will be used by a California Nuclear Power Plant for replacing the fuel rods in Combustion Engineering reactors rated at 1100 Mwe supplying electricity for 1.4 million homes. The modular design of the crane has several unique features: The telescopic mast that can raise up to 57′ high. The telescopic action is hydraulically operated. The mast has 300 powered mast rotation with a soft start and stop for smooth boom travel. The beam rotation is equipped with a mechanical slip-clutch to allow it to “break-away” to prevent damage in the event the crane comes in contact with other objects or is subject to excessive side-loading.

The lifting is provided by a high-lift chain hoist with 2000 lbs. capacity and 60′ of vertical lift. The hoist is mounted on a motorized trolley for positioning the fuel rods as precisely as needed.

The crane is equipped with an operator platform at the height of 40′ for visually controlling and manipulating the placement of the fuel rods.

All of the controls are remote, pendant-mounted, push button for flexibility and convenient use. The beam is equipped with dual festooning systems, one of which is for the low voltage multi-conductor cable for all the function controls. The other festooning is for the high voltage 3-phase power source.

The crane has three flange mounting points for installation that uniquely fit directly on to the nuclear reactor flange. The crane is not installed on the floor of the building for seismic considerations, so even if the floor collapses in the event of an earthquake, the crane stays put.

The modular form of the crane with telescopic mast allows it to be quickly assembled, pinned, and ready for operation in just a few hours, and then conveniently removed and stored out of the way in a corner of the building or other storage area until the next use.

The construction of the crane is 90% aluminum 6061 and 10% stainless steel, mostly welded sub-assembly, which are then bolted by stainless steel fasteners. The modular components utilize quick-release pins to avoid the need to turn nuts and bolts, which would also require that the crane be re-certified after each assembly. The attaching flanges to the reactor were built out of A36 steel welded construction providing a heavy-duty rigid mounting connection.

All the tests were performed at Air Technical Industries in Mentor, Ohio on a simulated nuclear reactor flange test fixture.

Upender Inverter with Conveyors

A Texas manufacturing company making large gearboxes for the petrochemical industry needed to invert a large heavy gearbox casting up to 8′ long x 6′ wide x 4′ high, weighing up to 10,000 lbs, in their machining and assembly process. The precision-built component had to be inverted 180° or up-side down and then down-side up several times during the process. Machined surface had to be protected from damage or scratching. Safety was an important consideration, protecting workers from stretching, reaching, bending and heavy lifting that causes back injuries. And of course, efficiency and timely delivery is also an important factor.

Upender Inverter with Powered Conveyors

Air Technical Industries of Mentor, Ohio came to the rescue, designing and manufacturing a special Upender Inverter equipped with heavy-duty powered conveyors for automatic loading. The Upender Inverter then securely clamps the casting, inverts it 180°, un-clamps it, then discharges the heavy machined parts automatically on to the awaiting conveyor.

The process is then repeated in reverse after one end is finished being machined. The whole process only takes two minutes of time. The mission repeats itself over and over again safely, securely and efficiently, producing quality components without any damage or injuries.

Hopefully, many more machines will be built for the petrochemical industry to help America become more self-sufficient and less dependent on foreign oil imports. There are thousands of other components that need to be inverted in industry, this is why ATI has standard Upender Inverters available from a capacity of 250 lbs and up to 50,000 lbs and sizes from 24″ x 36″ up to 96″ x 144″ of humongous jaw bites.

When a standard unit will not meet the need, ATI is flexible in making modifications to satisfy the needs and offer effective solutions to meet the customer’s application. The more challenging the task, the more eager the ATI team is to develop a practical solution.

The dumper will lift and invert up to 180°, dumping any shape or size of container desired, even a 55-gallon steel drum. Place any shape container in the specially-designed hopper, and it will transport, lift to desired height, and dump or invert the container.

Mobile Universal Dumper

Customers that utilize a variety of materials may receive them in a wide variety of containers. Even 30 to 40 pound containers that could be handled manually can cause serious fatigue from repetitive action. Materials of any kind stored in cardboard boxes, wooden crates, bulk bags, tote pans, 5-gallon to 55-gallon kegs and drums, plastic jugs, buckets, or anything that could not previously be grabbed and dumped, the Universal Dumper can handle it all.

The unit is mobile and self-propelled with variable speed control. The drive speed range is from 1 fpm to 4 mph and the steering is 90� left and right, providing a tight turning radius. It rides on 8″ diameter roller bearing mounted polyurethane-coated wheels. The unit is battery powered and the lifting mast tilts forward and back. All functions are hydraulically operated.

The dumper is able to dump to the left and right up to 180� – the unit can invert upside down. Dumping height is up to 7 feet. The uniquely designed dumping chute is V-shaped to retain control of the item, regardless of its shape. The “V” chute and the stop bars prevent the container from sliding out during dumping.

The benefit of this configuration is that it does not require grabbing and holding the container, because many types of containers are hard to grab or grip. Containers such as fiber drums, canvas bags, paper bags or smooth cylindrical items will now be easy to lift and dump.

The unit can also be loaded automatically by conveyor with the optional conveyor bottom. A container on a conveyor will roll right into the dumper hopper, allowing quick and efficient operation.

The unit is compact and slim enough to pass through doorways and narrow aisles. The overall height of the dumper in the lowered position is only 76″. A see-through mast allows the operator to see where the unit is traveling for precise positioning.

The Universal Dumper is an ideal tool for operations where there is a need to lift and dump many different shapes of containers at different or variable workstations. One machine will transport, lift, and dump. It will save time, improve safety, increase efficiency, make the job easier and improve the morale of the workplace by eliminating fatigue caused by manually handling cumbersome containers.

New Loading Dock Lift, Zero-Low Ground Level

ROLL-ON LIFT OFFERS SAFETY AND VERSATILITY

Zero-Low Dock Lift

Air Technical Industries announces a new design of the heavy duty dock lift table, with the lowered height of 0″ like a magic carpet laying on the floor, and then raising a load of up to 50,000 lbs.

The capability of the lift platform lowering to ground level significantly improves versatility and ease of operation where the load can be rolled directly onto the lift platform without the need of a ramp or pit in the floor.

ANY PLACE, ANY POWER

The Zero-Low Dock Lift can be used any place, any time on a flat floor for indoor/outdoor use. Ideal for use in low lying areas where a loading ramp is not feasible or not available for loading and unloading trucks or transferring the load from one level to the next higher level up to 120″, depending on the size and length of the deck.

The lifting mechanism is a dual-type scissors mechanism, synchronized for level and uniform lift by a torsion bar and special hydraulic flow divider. The lifting is hydraulically actuated by hydraulic cylinders with chrome-plated shaft for smooth operation and to prevent corrosion. The hydraulic system is equipped with a safety pressure relief valve to prevent overloading.

Variety of power sources are available for any kind of operation. The most popular for smaller lifts are 110V AC / single-phase motors, 230-460V / three-phase motors for heavier lifts, air powered for spark proof or flammable environments, battery operated for outside or remote area operations, and gasoline or diesel engines to operate larger lifts.

TMJC for aircraft manufacturing

Air Technical Industries has developed and built a very unique and versatile mobile Telescopic Mast Jib Crane with OMNI-DIRECTIONAL mobility for handling various components that need to be lifted during the aircraft manufacturing process.

Telescopic Mast Jib Crane for aerospace

The large prefabricated components weighing up to 3,500 pounds need to be lifted up to 36′ high, transported into position, and articulated into the precise orientation for assembly. ATI’s stationary Telescopic Mast Jib Cranes have been used in other similar operations. The new concept of modular design requires much more flexibility and OMNI-DIRECTIONAL mobility.

ATI developed a new design of Telescopic Mast Jib Crane with Omni-directional mobility that enables the production crew to reach over, under and if necessary, into the airplane to position components during the assembly process.

The new crane model with unique Omni-directional mobility allows the crane to travel in any direction 360° and it can turn within its own measurements (similar to the way a military tank turns). The crane’s mast, a rotating turret, is capable of swinging left and right fully loaded. The telescopic section of the mast is chrome plated for smooth travel and to prevent corrosion. It telescopes up to 36′ under-hook height. The beam of the crane has 13.5′ of reach and is equipped with dual hoists, one with a motorized trolley and the other a push/pull trolley to “float”, accommodating movement and articulation of the load. The two hoists are used to rotate components, such as the horizontal stabilizer, from vertical to horizontal position.

The mast rotation helps in placing the component precisely to the fuselage for fastening. The hoist lifting speed is variable up to 32′ per minute and the hoists operate independently. The beam of the crane is equipped with emergency stop bars to automatically stop operation in case it touches a stationary object to prevent any damage.

The mobile base has a round design since it travels in any direction. That makes it easy to go around corners and crowded areas. The base is built of heavy steel construction with built-in drive system. The power pack with counterweights, battery, controls, valves, battery charger, pump, and motor are all enclosed and protected while serving as counterweight. Opposite the power pack is a single mobile outrigger that rotates and travels with the mast. This system makes the unit a unique, compact, innovative, and functional design.

Propulsion is driven by two heavy-duty 24 volt DC gear motor driven polyurethane wheels controlled separately via joysticks for directional control and smooth acceleration and deceleration. It has infinitely variable speed from 0 to 3 MPH. The wheels have built-in automatic braking. The traction wheels can be retracted from the floor if towing should ever be required. The power pack consists of dual power systems. 24 volt DC (48V available) is used for propulsion, steering, turret rotation and telescopic mast action. The wire rope hoists, motorized trolley, and built-in battery charger are powered by 240/480 volts/AC/3 Phase.

In case of power failure, systems are all designed to hold the load securely and all functions stop and lock in its present position. Other safety features include: on-board fire extinguisher, battery monitoring gauge, audible alarm system, traveling amber warning light, emergency stop, and overload protection. Hydraulic system is equipped with a safety pressure relief valve and the telescopic cylinder has an over-center holding valve to prevent mast from lowering inadvertently in the event of a hydraulic system failure.

Various components need to be lifted and precisely positioned during the airplane building process:

  • Lifting the horizontal stabilizer from the shipping container, transporting it in a vertical position, then positioning it with the secondary hoist with the leading edge forward 90° to a horizontal position, and positioning it laterally with turret rotation for precise installation. Afterward, it is used for removal of the lifting fixture for storage and next use.
  • Lifting and positioning engine pylons and installing onto the wings to be fastened.
  • Handling and installing engine cowlings.
  • Lifting and positioning thrust reversers for installation.
  • Lifting, transporting, and positioning inboard & outboard flaps for installation.
  • Miscellaneous handling of tooling, jigs, or fixtures, with the ability to articulate into the proper orientation.

The Omni Directional Telescopic Mast Jib Crane is really a dream come true in helping to build planes of the future or for that matter handling, transporting, and positioning of large components in any operation precisely, safely and ergonomically.
