Why APPI:  As part of the upgrade for an existing waste water treatment facility, the City of Dallas, Texas, included portable davit cranes located at the screen structure to lift and lower stop logs and dewatering pumps.

Their application required 400 pounds of lift at a 60″ radius and 22 feet of hook travel distance in a package that could be easily moved between three work locations and one of our Columbia 20AAM portable davit cranes was a perfect fit.  The pumps and stop logs have a section of wire rope that is attached to them while they are in service so the hoist has a quick disconnect that accepts a ferrule on the bitter end of each wire rope assembly.

In operation, stop logs and dewatering pumps are lifted at three locations, each with a permanently mounted pedestal base, and then moved on a cart and positioned under another one of our 20AAM davit cranes.  This second crane is used to lift the stop logs and pumps two stories to the main floor.  This sequence is reversed when these components are returned to service.

Working closely with Archer-Western’s Construction Project Manager, Joshua Stombaugh, we were able to ensure our portable davit cranes met – or exceeded –  the requirements of the City of Dallas for this application.

The Columbia HR3-2000-4A34-L AC electric hoist features a continuous-duty gear motor selected to meet the customer’s speed requirement and a custom rotary limit-switch assembly with adjustable upper and lower limits for the 75′ travel distance. The hoist also features a cable tension roller and custom overhaul ball above the hook to help prevent slack line conditions when not under load.

The variable speed controls are housed in a NEMA 4X stainless steel enclosure with shielding to minimize internal temperatures during operation. An hour meter is mounted on the face of the housing to track the usage of the system. A speed potentiometer on the custom NEMA 4X hand-held pendant control allows for both accurate positioning and high-speed movement of cargo. In addition, a separate fiberglass enclosure houses a customer-supplied key card security system to prevent unauthorized use of the crane.

Why APPI: The Port of Ventura had an aging, stiff leg davit crane system that had performed well for fishermen offloading catch as well as assisting in raising and lowering vessel parts needed for refurbishing. After considering a number of options, APPI was selected as the supplier based on the design they conceived for the crane. The crane was subsequently manufactured in Oregon and shipped to the site for installation.

Why APPI: Like most big cities, the streets of San Francisco are mostly deserted at 4:00 AM. A few months ago, this stillness was broken when a tractor and lowboy pulled into an alley next to Union Bank at the California Building in the Financial District. After parking, a crew of three riggers went to work preparing the trailer’s load for a 24-story ride to the top of the bank. Shortly after that, a load block rigged with three parts of line was lowered from above, connected to the lift rigging and the new chiller for the building’s HVAC system – with a weight of six tons – made a quick, quiet and uneventful ride up to its new home. In less than half an hour, the alley was clear again, and the truck that delivered the load was out of downtown before the meter readers were on duty.

What was noteworthy about this pick is that it was made with a 7-Ton capacity guy derrick owned by Sheedy Drayage Co. of San Francisco that has been in service with them since it was built in 1992. Similar to units that were commonplace in high-rise construction sites until the mid-60s, the derrick used for this lift was most recently overhauled in 2011. The decision was also made to look for a replacement construction hoist system drum set. The one used the derrick was heavy, complicated to install, and difficult to operate due to its age and design.

When the general contractor for the work on the bank building approached Sheedy about this lift, it was clear that the guy derrick working from the roof would be far more cost-effective than bringing in a mobile crane with enough boom and jib to do the job – especially when the cost of permits to block the streets while the work was being performed was factored into the pricing equation. The unit Sheedy used for the lift breaks down into pieces small enough to ride on a freight elevator; after a short assembly and anchoring process is ready to work. Although it takes more time than raising the boom on a mobile crane, the return on investment is far higher for the guy derrick, while the total cost to the customer is lower.

Chris Gregori, Sheedy’s project manager, said the key to making the guy derrick work well for this job was adding a construction hoist system set from Allied Power Products, Inc. of Beaverton, OR. Featuring dual motors, dual brakes, and dual planetary reductions, each construction hoist in the waterfall set is capable of 7500 lbs of line pull on the bare drum with room for 2,700 feet of 1/2″ diameter wire rope on each drum. Line speed is infinitely variable from 0 to 316 fpm on the first layer to a maximum of 497 fpm on the top layer. Then, using a single joystick with proportional control to operate each drum and programmable “ramping,” they automatically return to the neutral/stop position when released by the operator. The boom swinger is the original – and very effective – manual system operated by one of the crew.

Gregori said the discussion as to the final hoist specifications was time-consuming as they wanted them to be as flexible as possible concerning other usages in the future. However, he added that the effort was worthwhile in the end as the hoists are precisely what they needed, and their performance and support from APPI have been excellent. This, says Gregori, is extremely important. This classic piece of equipment has already been scheduled for several more high lift applications, including one later in 2014 just a few blocks away from the California Building.

Why APPI: Unknown to many people are the extensive wetlands maintained behind the flood levees on the Mississippi River, the 4th longest in the world. The protected wetlands act as buffers that smooth out river water levels while providing recreational opportunities and providing a habitat for fish and waterfowl.

Jeff Vassalli, a project manager for Magruder Construction Co of Eolia, Missouri, was given the job of installing a site-specific, bi-directional water pumping system for the Corp of Engineers in one of these habitats areas. The system needed to be capable of moving 60,000 gallons of water per minute to ensure as stable a water level as possible. A barge-mounted pump with a flexible connector was specified to tie up next to either of the two pumping stations at this location and connect with another flexible coupling on the pump station side.

The connection on these 24″ diameter couplings is at water level. Therefore, Magruder required a jib crane to lift and position the couplings laterally. After examining several possibilities, Magruder suggested – and the COE approved – a pair of jib crane systems designed specifically for this job from Allied Power Products, Inc. (APPI) of Beaverton, Oregon. Equipped with APPI’s proprietary hammerhead trolley system, these jib crane systems feature a hydraulic hoist powered by a portable hydraulic power unit as there was no source of power at the site.

The hydraulic power unit from APPI is compact, reliable, and easy to move from storage to the job site and then from crane to crane. The cranes’ other notable features included a jib crane rotation locking mechanism and a lockable weather-proof housing to protect the hoist. Resistant to damage by design, the only exposed portion of the system when it’s not being used is the hammerhead trolley, a distant target high above the pumping stations.

Although these cranes were designed and built for this application, the startup testing and acceptance by the COE was, as Vassalli said, “Absolutely flawless.” As a result, both Magruder and APPI are looking forward to future opportunities where their respective skills and expertise can be put to work.
