HD2000 Allows Replacement of Communications Dish at the Greater Hartford Airport

2011-01-20T09:36:00.000-08:00

Job #72971

Customer:

LS Technologies

Location:

Hartford, CT

Application:

In mid 2010, Allied Power Products, Inc. (APPI) was asked by LS Technologies LLC to provide a hoist capable of assisting in the replacement of a defunct communications dish atop a 285 foot tower near the Hartford, CT airport.

LS Technologies, a company specializing in “network implementation and maintenance, engineering, and program management support” was contracted by the DOT to figure out how to lower and raise a 5.5 ft wide 300 lb antenna hundreds of feet. To add to the challenge, LS Technologies also faced the jarring cold of the brutal Connecticut winter. With installation taking place at 250 ft, wind chill brought temperatures ranging from 15 to -10 degrees.

As stipulated by the local contractor, those working on the installation were only allowed to work on the tower for twenty minutes because of the conditions. This made things difficult as it took nearly twenty minutes just to climb the tower. As a result, it took three days of work to complete the installation. To make this job possible, APPI provided an HD2000 AC electric hoist to assist in the replacement of the communications dish. Weather aside, by supplying a vehicle mounted hoist with a handheld control pendant, APPI was able to help LS Technologies safely complete their job

Historic Chandeliers Get a Welcome Lift

2006-11-03T17:00:00.000-08:00

When Portland’s beautifully restored Arlene Schnitzer Concert Hall opened in 1984, a pair of hand crafted, irreplaceable chandeliers were left in place to serve as reminders of the hall’s storied past.

These magnificent crystal lights have the unique distinction of having witnessed each of the hundreds, if not thousands, of live performances that have entertained theatre-goers since its opening as the Portland Public Theater in 1928. Suspended at 60 feet above the floor and weighing in at 350 pounds, the only way workers are able to clean these treasures and change their light bulbs is to lower them to ground level. Unfortunately, the two original hand cranked hoists that made this possible reached the end of their usable lives in the early 1990’s and were taken out of service due to safety issues.

After years of going without proper cleaning or light bulb replacement, the maintenance staff at “The Schnitz” was given the go-ahead to replace the worn-out hoists with two Columbia A/C electric powered units from Allied Power Products, Inc. in Beaverton, OR.

Tom Bugas, assistant operator of the theater says, “These new hoists have made a difficult and tedious job easy to perform. Our crew loves them and they worked so well we installed eight of them in the Winningstad Theatre to replace units that had been in place for several years but were not performing satisfactorily.”

With the retrofit of these compact hoists, the lights can now be safely lowered on a regular basis for maintenance and certification by a stage rigging inspector.

Portland Center for Performing Arts Executive Director, Robyn Williams, says, “It’s wonderful to have these cherished theater icons fully functional again. Not only do they provide an eye popping welcome to our attendees, they hint at the magnificent art occurring on our stage."

Umm Qasr - Synchronized Hoists for Boat Repairs

2006-07-26T13:28:00.000-07:00

Hoist assembly and testing at APPI

It was mid-afternoon at the Umm Qasr Naval Base on the southern tip of Iraq. Rick Fedrick, a seasoned project manager for Weston Solutions of West Chester, Pennsylvania, watched intently as a 90-foot Iraqi Coastal Defense Force (ICDF) patrol boat rose slowly out of the Persian Gulf on a steel platform. Although he had become acclimated to the 117 degree heat, he says now that he was “sweating a little” over the fact that his and Weston's reputations were riding on the 10 slim pieces of wire rope lifting the vessel.

Fedrick arrived at Umm Qasr in January of 2004 and took charge of the rebuilding effort of that facility as contracted to Weston. Within three months, using local contractors and laborers, he had built two barracks, a dining hall, a classroom and a warehouse. Based on that success, Fedrick was given the opportunity to bid on removing and rebuilding a boat lift destroyed during the invasion of Iraq in March of 2003. Having the lift operational was identified by the Iraqi Ministry of Defense and the Coalition Provisional Authority as being crucial to ensuring the five patrol boats in the ICDF were properly maintained and able to fulfill their mission to counter terrorism, smuggling and piracy.

Although Fedrick was a naval architect, he knew that once the 250 tons of twisted steel remaining in the water from the old lift platform were removed, getting a system in placed that would meet his 1,000 ton capacity requirement was going to be more challenging than erecting buildings. In addition to the salt water atmosphere, sand and extreme heat that went with the location, the system he was responsible for specifying needed to be safe and reliable for the ICDF crews who would be operating it long-term.

The assembled platform

Given his experience with the local contractors he had worked with on the building projects, Fedrick felt he could handle rebuilding the lift platform itself. But, as he said, “Hoists are not my area of expertise.” Based on Weston's previous experience with Allied Power Products, Inc. (APPI) in Beaverton, Oregon, Fedrick contacted their president, Bob Peterson, and described his requirements. Fedrick says the reply from Peterson was simple, “Tell me exactly what you need and we'll provide you with a system that meets those requirements.”

In order to use as much of the existing lift structure as possible, Fedrick specified 10 hoists with a total capacity of 1,000 tons. Fedrick also added the caveat that after traveling 32 feet vertically, the platform could be no more than 1/16th of an inch out of plane over its 265 foot length.

Testing the hoist system

What APPI proposed to Fedrick was a system that included not only the hoists, but also complete motor controls, 10 load blocks with eight parts of line, wire rope spooling compensators, and the wire rope and electrical wire for both power and controls – even the mounting bolts for the hoists were included. Fedrick says the only thing Peterson did not offer to include were his services as an on-site adviser.

When Weston was awarded the contract to rebuild the ship lift, a purchase order contract was issued to APPI for the hoist system. In December of 2005, Fedrick and Champak Sadhu, Weston's lead mechanical engineer, made a trip to Beaverton where APPI had laid out the entire system for familiarization and run testing. After acceptance, the entire system was loaded into three containers and sent by sea to Umm Qasr.

Since the day the contract had been awarded to rebuild the ship lift, Fedrick and his crews had been working to remove and rebuild the old platform sitting in the water between the two wings of the ship lift dock. At the same time, they were also designing and building the 10 lift towers and hoist mounting pads in anticipation of the arrival of the containers from APPI. Without the benefit of any form of fabrication facility, the work was completed entirely on site just before the hoisting equipment arrived.

After bolting down 10 hoists, hanging 10 pairs of load blocks and reeving 10 lengths of wire rope, the controls were connected and system testing began. Over a period of a month, the platform was tested for both gross and off-center loading. Fedrick said that “Once we had everything dialed in, it made no difference to the hoists what the load was or where it was positioned – it lifted perfectly level under all conditions. There's no question APPI was the right choice for this job as their system just flat worked right.”

Rick Fedrick shows a big smile after successful operation

On May 22, 2006, Fedrick watched as a team of ICDF sailors successfully guided Patrol Boat 5 into the cradle on the ship lift, secured it and lifted it to dock level. He may have been “sweating a little,” but with the system operational and training complete, the rest of his job was “just paperwork.” In early June of 2006, with both the base facilities and the ship lift in the hands of the ICDF, Fedrick returned home to his family in the States.

Columbia Winch on the ATHLETE Lunar Rover

2005-10-20T10:20:00.000-07:00

The All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) is a new mobility platform developed for potential lunar operations. This six-limbed rover is designed to traverse quickly over benign terrain by rolling, traverse rough and steep terrain by walking, as well as perform general manipulation of tools and payloads. This flexible robotic platform will provide a mobile base for pressurized lunar habitats allowing for long range surface exploration and crew transport. It will also enable in-situ construction of lunar assets providing astronauts with the ability to assemble, maintain, and service a wide range of cargo.

To explore extremely rough and steep terrain, such as the base of an impact crater, safety lines are required to ensure the stability if the vehicle. For use on steep slopes (> 20 deg) a rappelling winch has been incorporated into a face of the rover as shown below. This winch uses a brushless DC motor with a safety brake and a 16:1 planetary gearbox. At the top of the hill, the ATHLETE vehicle can secure an anchor using a 2 m long auger bit driven into the ground by the tool mechanism. The rappelling line is attached to the auger and as the vehicle descends down the hill a cable spool that is carried on the vehicle is paid out. When the vehicle is stationary, the winch brake is engaged and power is not required on the winch to hold the vehicle. As the vehicle moves, the brake is released and a constant current controller on the winch motor delivers approximately constant tension on the line as additional cable is released. The rappelling line offloads the downslope weight of the vehicle and allows the rover to safely drive and/or walk down steep slopes without additional demand from the wheel or joint actuators.

The ATHLETE vehicle is a complex robot with more degrees of freedom that any other planetary rover. This complexity, however, comes with the benefits of capability and flexibility. The ATHLETE rover can traverse terrain that no other planetary rover can traverse. It can negotiate a step nearly equal to its fully extended limb length and more than three times its wheel diameter. It can act as an exploration rover, a crew transport vehicle, and a construction asset on the lunar surface. This wheel-on-limb rover is highly adaptable and will potentially play a key role in man’s return to the moon.

DC Powered Ambulance Hoist

2004-10-21T16:44:00.000-07:00

A North Carolina ambulance manufacturer recently drew upon Allied Power Products, Inc.’s (APPI) expertise to provide a DC powered hoist that would help ambulance and emergency personnel load wheeled stretchers carrying bariatric patients.

From their extensive product line of hoists and winches, APPI selected their DC500 12 volt strap hoist. When not under tension at all times, a strap eliminates the spooling issues associated with wire rope. In addition, patients benefit from the smooth pulling of a strap because it does not jump from layer to layer. The synthetic fabric construction of the strap is also much cleaner and easier on the hands of ambulance personnel as it does not require lubrication or burr.

The APPI DC500 is equipped with a 1.1 hp motor which provides a line pull of 1,100 lbs. and a line speed of 17 feet per minute. An overall weight of 25 lbs., a footprint of 14" x 6.5" and a height of 6.4" makes it ideal for mounting in small spaces.

A 27 foot long strap reduces the distance a stretcher needs to be pushed by hand before the load can be transferred to the hoist and pulled into the ambulance. A hand held pendant controls the hoist.

Strap Hoists for Aircraft Assembly

2004-06-06T08:04:00.000-07:00

When faced with the need to rotate a large aircraft nose assembly 180 degrees in order to install landing gear modules, a major aircraft manufacturer utilized a pair of Columbia Strap Hoists from Allied Power Products, Inc. (APPI).

APPI provided two of their standard H650 AC electric hoists with a strap drum option for this application. Each one winds a 2” wide strap flat on the drum which eliminates the problems associated with wire rope spooling. Installed on a custom rotation fixture that is suspended from an overhead crane, each hoist has 650 lbs. of lifting capacity at a speed of 21 feet per minute.

Two 15 foot long pendant controls allow precise positioning and electrically released brakes ensure reliable load holding while the nose assembly is being rotated into position.

Traction Drive Hoist System

2004-02-06T14:13:00.000-08:00

Allied Power Products, Inc. (APPI) recently designed a custom traction drive hoist system for the Washington Department of Transportation (WSDOT) to assist in removing paint from the suspension wires on the Tacoma Narrows Bridge.

After struggling to make an existing twin winch system work properly when raising and lowering a paint stripping tool, WSDOT site supervisors turned to APPI for help.

Specifically, WSDOT wanted to end the practice of cutting the wire ropes on the hoists each time they moved to a new suspension wire and at the same time make it easier and safer for workers to make each move.
After reviewing the application, APPI produced a purpose built traction drive hoist that uses a single, continuous loop of wire rope to make moving it quick and easy.

Weighing 70 lbs, and with overall dimensions of 22” X 23” X 14” high, the prior problems with getting set up to work on a new suspension wire have been eliminated.

Equipped with a ¾ hp AC motor, the unit provides a maximum of 750 lbs of line pull at a speed of 16 feet per minute. A hand held pendant was provided for operator convenience.

This new hydraulically powered winch system was engineered by APPI for use on a "D8" size dozer. The system is specifically designed to provide an operator full control, including inching capability, while raising and tensioning high-power transmission lines.
With power provided from the dozer's hydraulic system, each of the three winches in the system has a maximum line pull capacity of 60,000 lbs. Configured to spool up to 275' of 7/8" diameter wire rope and operate by individual controls for pull, speed and free-spooling; this system provides power and precision control with capacity.

A wide range of other hydraulic winch systems with a nearly infinite selection of line pulls, line speeds and wire rope capacities are available. Complete information and application assistance from APPI are available upon request.
