At Overhead Crane & Conveyor Service Corp, we work with premium quality Thern brand winches and Davit cranes. Thern has been designing and manufacturing lifting products that are built in the US for over 60 years. Thern produces power and air winches in a variety of configurations for use in a range of petrochemical, manufacturing, wastewater, and construction applications. Features such as manual, pendant, or remote control options and variable speed models make Thern’s heavy duty winches adaptable to a wide range of applications. With lifting capacities up to 100,000 lbs. on powered models, Thern winches can be used in a wide array of facility types.


Thern’s line of Davit cranes range in lifting capacity from 500 to 3,000 lbs., allowing us to select the proper capacity for any given job and budget. Cranes vary in features by model, but all have an adjustable and telescoping boom, 360° rotation, and the ability to adjust the height of the crane under loading via a ratchet-style screw jack.

At Overhead Crane, we take pride the quality of our work and use equipment that is produced by the most reputable original equipment manufacturers in the industry. Our team works to maintain relationships with top quality manufacturers to ensure that customers’ projects are completed to spec and on-time. While we can easily customize equipment as needed, using OEM parts and equipment where applicable makes sense both in regards to overall costs and the timeline of a project.
