WHY APPI:

Boating enthusiasts understand the challenge of safely and efficiently deploying and retrieving dinghies from larger vessels. When Rick Crossland needed a reliable electric hoist solution for his existing vessel davit system, he collaborated with Allied Power Products, Inc. (APPI) to identify the ideal solution that would meet his specific marine application requirements.

After thorough discussions about the vessel configuration, weight requirements, and operational needs, Rick and APPI jointly determined that the Columbia HC1100 AC electric hoist would provide the optimal combination of lifting capacity, speed, and reliability for this marine application.

Key features of this vessel davit solution include:

1. Sufficient line pull capacity of 1,100 pounds, providing ample power for lifting and lowering the dinghy safely in varying marine conditions.
2. Convenient quick-disconnect pendant control, allowing for flexible operation and secure storage when not in use – an important feature identified during collaborative discussions.
3. Marine-grade components engineered to withstand the harsh saltwater environment, addressing a critical concern for longevity in marine applications.
4. Compact design specifically selected to integrate seamlessly with the existing davit structure on Rick’s vessel.

By implementing this collaboratively developed hoist solution, Rick has significantly improved his dinghy management capabilities. The system provides enhanced safety, increased convenience, and reliable performance for routine dinghy operations.

WHY APPI:

P & M Mechanical, Inc. faced a specific challenge in their construction project: efficiently and safely transporting materials and mechanical units between ground level and rooftop. With precise requirements outlined in their project specifications, they needed a reliable solution that would meet these exacting standards.

Terry Wideman, President of P & M Mechanical, Inc., explains their collaborative approach: “We had a project that spec’d out using a hoist and davit crane to raise and lower construction materials and mechanical units between the ground and roof levels. We called Allied Power Products, Inc. and after some application discussions, we were comfortable with anticipated performance and we moved forward with purchasing their 500 lb. davit crane and HD670 AC electric hoist.”

Through consultative discussions, P & M Mechanical determined that the Columbia rooftop crane and hoist system would provide the optimal solution for their specific needs.

Key features of this solution include:

1. High line capacity suitable for construction materials
2. Superior line speed for efficient material transport
3. Compact, roof-friendly design with secure pedestal mounting
4. Reliable performance in demanding construction environments

According to Wideman, the construction project has progressed well, with the Columbia rooftop crane and hoist proving “well suited for safely and efficiently bringing materials to the rooftop construction area.”

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.
