ABOUT THE COMPANY
Scott Losmandy, owner of Hollywood General Machining, introduced the firstPorta-Jib to the professional film and video community in 1989. It was an immediate success because of its modular design, its superb craftsmanship, its ability to accommodate heavy cameras, its ease of assembly, and its portability. This was fine for the Hollywood market because by its standards (remember that in 1989 camera systems were quite heavy) our Standard Jib was remarkably portable. However, the video and 16mm film market wanted even greater portability. They loved the jib, but it was too heavy for their light weight tripod systems, and they did not want to purchase a 35mm style tripod system just to support a jib. This gave rise to the Traveller Jib.
The Traveller is so small that when it is in its storage position, it is only 31 inches long. Yet it unfolds and telescopes out to become a full size front-operated jib. And at 29 lbs., it is light enough to be supported by a 100mm style tripod, which is standard in 16mm and video production.
The Vector Balancing System was then introduced for all of our Jibs. This clever idea allows us to remove the inertia inherent in all jib arms. The Vector System helps one immensely in coming to a stop without the bounce normally associated with lightweight jibs.
Our next big break-through product was the Spider Dolly and FlexTrak system. FlexTrak comes in 40 foot lengths, is made of a rubber tubing reinforced with a steel lining which allows one to shape a dolly move from straight to curved almost instantaneously. Our goal was to not only provide a new tool for designing interesting moves, but to also allow one to have a complete dolly system with 40 feet of track that would fit into a standard vehicle. The dolly itself is a modular system that can be either a 3-leg version for use with a tripod, a 4-leg version that carries an operator and has an adjustable column and a seat that rotates 360 degrees around the column, or it can be miniaturized into a trolley system for table top work.
Following this idea, we created the Porta-Glide sleds with the multi-dimensional wheel system. A problem with dolly sleds in the past was that the heavy weight load of a dolly, two operators, and a camera system caused the skate-board style wheels to immediately develop flat spots when at rest. Our system solves the flat spot problem. We use 16 different diameters for the 16 wheels that are on each sled. This has been extremely well-received by the camera operators and dolly grips who have had the opportunity to work with this new concept. Our sleds also have floating arms with bearings that accommodate curved track much better than most competing sleds.
