Mark C. Pope Associates, Inc. – A Value-Added Dealer for Hobart Ground Power

MCP has been a dealer for Hobart Ground Power equipment for over 35 years. During this time, we have spent a great deal of time in our market speaking with customers regarding their requirements, operational difficulties, budget concerns and how they serve their customers. These conversations have helped us to discover needs that can’t easily be met with off-the-shelf configurations of ground power equipment; that is why we offer custom engineered solutions to help our customers do their jobs more efficiently. We have engineered several stationary distribution systems for regional airlines, designed the current trailer system that is currently used on Hobart’s GPU-400 and GPU-600, re-engineered and manufactured obsolete items for early model GPUs, designed remote mounted controls for GPU configurations and engineered optional equipment to reduce handling expenses when dealing with ground power equipment. One of our most current projects was to develop a trailer system for the new 2300 series frequency converters.

Designing for a Targeted Market

2300-widthThe 2300 Series Ground Power unit is a frequency converter that can be configured to output from 30 to 90kVA. This GPU is designed to provide power for general aviation, FBO’s (fixed base operators) and regional airlines. One of the highlights of this particular product is the size of the machine. In a horizontal configuration, it measures only 46″L x 22″W x 24.6″H.

The main focus of this project was to design a trailer system that made the equipment easy to operate while also maintaining the small footprint of the design. As you can see by the image, the trailer assembly maintains its narrow width and can easily fit through a standard doorway. This unique size allows the user to have a mobile unit that also respects the operating floor space. Floor space is always at a premium and the 2300 can easily fit in some of the smallest areas of your operation with this trailer.

Ergonomic Design for Easy Operation

2300-tow-barThe braking system is incorporated with the front pull/tow bar to allow for easy operation for the user. Lifting up on the pull/tow bar will apply a break to the front caster of the trailer system. This design provides more control to the user when moving the machine by hand and also makes sure that the break is actuated whenever the machine is put into place. The pull/tow bar lock can easily be disengaged with your foot making it easy to prepare for re-positioning, and the same locking feature will automatically engage when the pull/tow bar is placed back in the upright position.

Designed for Serviceability and Access

2300-modular-controlsThe 2300 can be configured with a remotely mounted operator control that can be used with several configuration choices. One of the goals with this design was to keep the height as low as possible to make it easier to maneuver around aircraft wings and other low hanging obstacles. As you can see in the image to the right, we are mounting a control box to the front of the machine at its highest point. This positioning offers the best protection for the device while also making it easy for the operator to see the readout and adjust the operation of the machine.

You will also notice that the design of the trailer system does not interfere with the serviceability of the ground power unit. The side panel of the machine has been removed showing you access to the modular design of the GPU. This design makes it easy to perform upgrades, repairs or maintenance to your ground power unit.

Extreme Maneuverability

2300-finished-mockThe trailer project is configured with a fifth-wheel design. This design provides the smallest turning radius and the most maneuverability for any machine in the class. The dual front casters, wide stance and low center of gravity gives this machine and trailer package the best stability possible. The addition of fork-lift pockets to the frame allows for easy transport and relocation of your equipment without the dangers of an unbalanced/unstable load.

One other design feature is the non-marking solid rubber caster. These casters make it much easier to move the equipment by hand and they will not mark up painted or epoxy floors. The tray assembly on the top of the machine also gives you space to stow cables while on the move.

Designed and Fabricated by Experienced GSE Personnel

2300-brianThe technician working on this project is our lead fabricator, Brian Fusian. Brian has been with MCP for over 15 years and has been in the GSE industry for his entire career. His fabrication skills were strong before he came to work with MCP and he has certainly been a big part of our success in the ground power market.

Scott O’Connell is the division manager at MCP for the ground power division and he is also the designer/engineer for this project. His conversations with customers, engineering background and industry experience helped him to design a trailer system that will be a perfect fit in your operation.
