3.1 Important notice
It is the responsibility of the owner/user to install, inspect, operate and maintain this hoist in accordance with
OSHA regulations and ANSI/ASME B30.16, “Overhead Hoists (Underhung)”, along with any state or local
codes/ordinances as applicable. If hoist is installed as part of a total lifting system (trolley, crane, monorail,
etc.), or if below-the-hook lifting devices will be used, it is the responsibility of the owner/user to comply with
any standards or regulations involving those additional elements of the system.
4.0 Product introduction
Your JET variable speed hoist is designed and constructed to provide consistent, long-term operation if used in
accordance with the instructions set forth in this manual.
JET VOLT hoists are available in either 230 volt/dual phase; or 460 volt/3-phase configuration, as well as
varied chain lengths.
The Variable Frequency Drive, or “inverter,” offers variable speed within a pre-established range. This allows
lifting or descent of loads at reduced speeds without having to toggle the up/down button, thus providing
efficiency and reducing stress on control contactors.
The magnetic disc brake provides dependable and rapid stopping of chain movement without hook drift, and
produces less wear on brake elements than standard mechanical braking systems, thus reducing maintenance.
The hoist is also provided with thermal overload protection and limit switches.
This hoist complies with ANSI/ASME B30.16 and HST-1 standards.
