Many people think of a winch as a device that pulls horizontally, when in fact, Thern winches can be placed in virtually any orientation (floor mounted, wall mounted, or underhung) and can pull both horizontally and vertically when properly equipped. Electric hoists will require an automatic brake for vertical lifting applications, while winches for horizontal pulls would not necessarily require a brake. Please reach out to our sales staff to discuss your project and the best solution to fit your needs.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=\u00a0\u00bbWhat are the advantages of a motorized davit crane vs. a motorized jib crane?\u00a0\u00bb tab_id=\u00a0\u00bb1689103469123-26b44cde-6b72″][vc_column_text]If the weight, height, and reach requirements fit within a Thern davit crane capacity, a davit crane will be easier to install, operate, maintain, and is generally more affordable. Additionally, many of Thern\u2019s davit cranes are more portable than a motorized jib crane. If you buy numerous bases, you can move the cranes to different locations to solve multiple lifting applications with just one crane.<\/p>\n

A stainless-steel davit crane, while somewhat heavier, provides the ultimate solution in corrosion resistance and lifting capacity.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=\u00a0\u00bbHow do you calculate the fleet angle of wire rope?\u00a0\u00bb tab_id=\u00a0\u00bb1689103542367-c0c5ffb3-7932″][vc_column_text]Fleet angle is the angle between the wire rope and an imaginary line extending perpendicular to the drum. The fleet angle varies with the distance between the lead sheave and the drum. Using the correct fleet angle of wire rope will ensure your winch is operating at its full capacity and not causing undue wear.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=\u00a0\u00bbWhat are air winch safety best practices?\u00a0\u00bb tab_id=\u00a0\u00bb1689103558542-ab661923-01dd\u00a0\u00bb][vc_column_text]In addition to all winch safety, which includes air winch safety, best practices are to:<\/p>\n
