5.0 Product introduction
Your JET dual-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 TS series hoists are available in 230 volt, 3-phase or 460 volt, 3-phase power, as well as varied chain lengths.
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 equipped with upper and lower limit switches, and a slip-clutch to prevent overloading.
This hoist complies with FEM standards.
6.0 Glossary
Key terms helpful to the hoist operator:
Creep speed: Slow, constant, fixed rate of motion
of a hoist.
Duty cycle: The amount of work a hoist can perform
in a given period of time, generally measured by
maximum run time and number of starts within that
period. Duty cycle ratings are designated H1
through H5.
Duty class: Identifies the type of service for which
a hoist is designed, designated A through F.
Headroom: Minimum distance between saddle of
top hook to saddle of load hook, measured when
load hook is at upper travel limit. Smaller headroom
allows a hoist to fit in tighter work spaces.
Hook saddle: The inside arc of the hook which
contacts the beam (top hook) or where the load sling
is seated (load hook).
Toggle or “bump fire”: Rapid press and release of
a control button to raise or lower load in intermittent
steps. (A variable frequency drive in lowest speed
range often eliminates the need for toggling.)
Overtravel limit device: A device for limiting
upward or downward travel of the load hook at the
extremities of its lift. (If activation of the device alters
the electrical circuit within the machine, it is often
called a “limit switch.”)
Load block: The assembly of hook or shackle,
swivel, bearing, pins, sheaves and frame
suspended by the chain.
Electro-magnetic brake: A stopping device
controlled by the application of electrical current to
the coil of an electromagnet, which draws away an
armature allowing rotation of the shaft. When the
magnet is de-energized, the armature moves back
toward the brake face and squeezes together
friction discs – the torque is applied to the hub and
stops shaft rotation.
Overload limit device: A mechanical or electrical
device that prevents the hoist from lifting when
excessive load is applied.
Rated Load, or Capacity: The maximum load
weight, usually labeled as tonnage, which the hoist
is designed to handle as designated by the
manufacturer.
Reeving: The system in which a chain or rope
travels around a running sheave.
Running Sheave: A sheave which engages the
chain/rope and rotates as the load block is raised or
lowered. Also called “load sheave” or “load
sprocket.”
