We put the same level of attention to detail into each of our hoists as we do our cranes, ensuring that every customer can access a complete solution of exceptional quality. We can create three types of hoist units. These units include the HI, HL, and HD hoists.

To learn more about the hoists available here at Zenar Corporation, please contact us.

HD Hoist

HD Hoist

This hoist is our most heavy duty hoist unit and it is used in places where equipment can be serviced from the top of the trolley deck. This hoist is used in situations where there is going to be heavy to severe service.

HL Hoist

HL Hoist

This hoist is a step up from our HI model and it is the maintenance friendly version of the HI hoist unit. This hoist system will used to assist in jobs where there is moderate to heavy service. This hoist comes with foot mounted hoist motors.

HI Hoists

This unit is our low duty, light service, and low profile hoist. The hoist is mainly used in facilities where there is not a lot of headroom above the crane. This hoist unit comes with a hoist gearbox integral to the trolley end truck, and c-face mounted hoist & trolley motors.

HI Hoist

Standard Design Features

  1. Vector Duty A.C. induction motors which are totally enclosed, non-ventilated with sealed anti-friction bearings and standard NEMA frame design. Motors can provide 100% torque at zero speed, have class “H” insulation, 60 Minute time rating, and operate in a 50 degree “C” ambient temperature.
  2. Zenar provides a dependable spring-set and electrically released hoist brake. You never need to adjust a Zenar brake for lining wear, as our brakes have an automatic self-adjusting feature. Available brake styles are: A.I.S.E mill duty A.C. thruster or D.C. rectified shoe; or D.C. rectified disc.
  3. Zenar uses two hoist limit switches to limit hook motion. A geared limit switch measures drum revolutions and prevents over winding or backward winding of hoist rope onto the drum. Plus a paddle type switch, that is hook block actuated in hoisting mode. Each switch, when tripped, turns off electrical power to the hoist motor.
  4. The heavy duty hoist gear case is an enclosure that is an oil tight foot mounted steel weldment, precision machined on a computer controlled machining center. The gear train consists of 20 degree full depth helical and spur cut tooth forms. Gears run in an oil bath with all bearings being splash lubricated. All bearings are encapsulated in steel bearing capsules.
  5. Hook block is a rugged machined steel weldment. Rope sheaves rotaate freely on anti-friction bearings. A forged hook turns 360 degrees on a thrust bearing and is equipped with a safety latch.
  6. Top running sheaves and equalizer rope block are completely accessible from above the trolley. This makes inspection or changing of the hoist rope safer and more convenient.
  7. Drums are machined steel weldments with right and left hand rope grooves for a double reeved rope system. Double reeved rope systems provide for true vertical lift and equal wearing mechanical components in the rope system.
  8. Hoist rope construction is 6 x 37 improved plow steel with an independent wire center. The rope does not have special end fittings and is attached to the drum by two dead wraps and bolted cable clamps.
  9. Four rotating axles, double flanged, hardened wheels support the trolley. Anti-friction bearings are encapsulated in sealed housings.
  10. Trolley gear reducer contains helical, 20 degree full depth steel gearing. Bearings and gears run in an oil bath. Reducer is shaft mounted to the axle.
  11. Trolley frame is a steel weldment with frame being precision machined before installing the trolley and hoist machinery. All individual components are accessible from above frame, allowing for ease in inspection and maintenance.

All of these components work together to make up an efficient hoist system.
