The David Round Company's Lo-hed hoists are made for continuous use
The David Round Company's Lo-hed hoists are designed to feature H4 duty ratings and are made for demanding lifting applications from 1/2 to 15 tons. The hoists are made to be customized to operate on beams with 3" to 14" or greater widths. The Lo-hed hoist design is constructed to maximize overhead clearance to provide additional workspace over assembly bays. A 1 ton hoist is made to require less than 14" of headroom; a 15 ton hoist made to require only 36" of headroom.
Lo-hed hoists are made for continuous use. In addition to its H4 duty rating, Lo-hed hoists are designed to be supplied with features to help position loads with precision. These are made to include true vertical lift (double-reeved), enclosed in-line gear train with oil lubrication, mechanical load brake, electric motor break, emergency upper limit switch, reversing controls and thermal overload protection.
