Hoists Direct sells electric hoists that are manufactured in accordance with B30.16, Overhead Hoists (Underhung) from a variety of manufacturers including Coffing Hoists, CM Lodestar, Budgit, Harrington Hoists and Shaw-Box. B30.16 is a manufacturing standard for powered hoists from the American Society of Mechanical Engineers (ASME). The standard includes provisions that apply to the construction, installation, operation, inspection, testing, and maintenance of overhead underhung and stationary hoists including hand chain-operated, chain hoists and electric-powered and air-powered chain and wire rope hoists used for, but not limited to, vertical lifting and lowering of freely suspended, unguided loads that consist of equipment and materials. B30.16 also includes requirements for a hoist that is used for a special purpose such as tensioning a load, non-vertical lifting service, lifting a guided load or lifting personnel. The most common features of the B30.16 standard relate to markings, controls & identification.
Markings
Included in the standard is how a hoist or its load block should be marked. The standard includes a requirement that hoists and load blocks are marked with the rated load and that the rated load is legible from the ground or floor. All of the hoists that we sell have the rated load on either the hoist or load block.
Controls
Included in the standard is how electric-powered or air-powered hoists should be controlled. The standard includes a requirement that the pendant, pull cord or radio controller for each electric or air hoist shall be marked to indicate the direction of the resulting motion. In addition, the standard includes provisions to cover the use of air or electric hoists in large manufacturing facilities with multiple hoist brands and types: in locations or areas where multiple electric-powered or air-powered hoists are used, the arrangement of the control actuator markings for directions of motion on pendant push button stations and radio-controlled transmitters should be the same for all hoists in the location. Employers and end users and their associated electricians and installers should pay attention to the up/down motion to ensure compliance with the controls portion of ASME B30.16.
Identification
Included in the standard is how hand chain, electric (powered) and air hoists are identified. The standard includes a requirement that hoists shall be marked with manufacturer's identification information. For hand chain hoists, the information shall include items such as the name of the manufacturer and the manufacturer's model or serial number. For electric or powered units, the information shall include items such as the name of the manufacturer, the manufacturer's model or serial number, the voltage of AC or DC power, the phase and frequency, the full load amperage and the hoist duty service classification. For air units, the information, shall include items such as the name of the manufacturer, the manufacturer's model or serial number and the rated air pressure.
