Over the last five years I have had numerous substation construction projects that required transporting large units of substation equipment; mostly transformers and circuit breakers. It has been my responsibility to contract and schedule oversized hauls that range from 200,000 to 500,000 pounds.
During these projects I have worked closely with five different heavy haul contractors to move substation equipment. So please understand that my review of the work done by Precision Heavy Haul is based on a wide range of personal experience.
Precision Heavy Haul has consistently out-performed the other haulers in these areas:
Precision always drives a route checking clearances, turning radii, road conditions, and bridge and culvert load ratings. Traffic control, pilot vehicles and permits are always obtained. Local utilities (telephone, cable, fiber and electric) are notified and respected. Curfews are observed. In every way, Precision has put together a work plan that has been successful and has supported Arizona Public Service's wish to cooperate and comply with permitting agencies and other utilities.
To accommodate specialty loads Precision has engineered and fabricated specialty equipment for Arizona Public Service such Schnabel attachments and "high center-of-gravity" beams. Precision keeps all their equipment clean and well maintained which has resulted in trouble free performance at the jobsite. Precision has developed a system of skids and hydraulic pushers that allow effective control when moving a large transformer. This system has much less risk than the traditional jack and roll method.
