The document is a specification for a truck-mounted hydraulic-powered crane with specific load rating requirements. The crane must have a minimum load rating of 32,000 pounds at a 5-foot load radius. However, it is further specified that when all booms are retracted and the load radius is 3.05 meters (10 feet), the minimum load rating should be 16,200 pounds (7,348 kilograms). The document is prepared by the Texas Department of Transportation (TxDOT) and is intended to be made available through the National Institute of Governmental Purchasing (NIGP). It includes general clauses and conditions, as well as specific specifications for the crane. The document emphasizes that the equipment must be new and meet all safety, health, lighting, and noise regulations. It encourages manufacturers to comply with environmental standards and use recycled materials. Quality is also emphasized, with a suggestion for manufacturers to adopt ISO standards. The document provides measurements in both the English and metric systems, with the English system taking precedence in case of conflicts. It includes requirements for boom tip height and load ratings, which must be met by the crane. Examples of acceptable crane models are provided, but respondents are cautioned to carefully read the specifications as there may be special requirements not commonly offered by manufacturers. The document references industry standards from the American Society for Mechanical Engineers (ASME) and includes device rating requirements for the crane.
