ZEPHYR ARMY TYPE TROLLEY HOIST

MODEL 1311 PLAIN TROLLEY & MODEL 1312 GEARED TROLLEY
1/2 to 2 TON. Zephyr Army Trolley hoists in these capacities are
notable for light weight and ability to traverse minimum radius curves
freely, since the trolley units swivel. Construction is ingeniously simple.
A standard Zephyr spur geared hoist is suspended on a special load
bar carried at each end by a lifetime lubricated precision ball bearing
equipped two wheel trolley. Trolley units are adjustable to beam size
and are interchangeable. Plain trolley may be replaced with geared
unit at any time, as required. Wheels have convex-machined treads
that will maintain roundness through long use.
1/2 TO 2 TON HOIST
3 TO 10 TON HOIST
3 to 10 TON. These units are compact combinations of the larger
capacity Zephyr spur geared hoists with integrated four-wheel trolleys
with duo-sealed Timken-bearings. The result is a unit of minimum
dimensions retaining full operating advantages. Modified conventional
Army Type construction not only provides protection of heavy gauge
rolled steel side plates, but also added advantages of adjustability to
beam sizes, as well as adaptability to comparatively tight minimum
radius track curves. All trolley wheels are easily adjustable for bearing
wear.

Zephyr Army Type Hoists are available for wide flange sections, monorail runways, or I-beams outside the normal adjustment range.
Consult us for details.

MECHANICALLY ENCLOSED Heavy steel
housings keep out most foreign material, protecting
precision machined working parts.
CHAIN STRIPPER Ductile Iron.
LOAD BRAKEPositive action. Weston type with
uniform composition lining and quiet-action forged alloy
pawl.
GREASE TIGHT-ENCLOSED Complete enclosure,
sealed construction keeps lubrication in, making the
Chester Zephyr a lifetime-lubricated hoist under normal
conditions. No protruding parts, resists snagging.
SHOCK RESISTANT Heavy gauge steel in the
stamped covers, two rolled steel sections in the frame,
and use of strong alloy steels in suspension members
make the Zephyr a sturdy hoist.
EASIER HANDLING Lightweight, compact
construction makes the Zephyr portable to practically
any location in the plant, able to operate in tight corners.
EASY DISMANTLING Making periodic inspections,
or replacing chains or parts, requires only a small wrench
and screwdriver.
LOAD CHAIN GUIDE Completely shrouds load
sheave, guides chain into load wheel and efficiently
shields these parts from entry of foreign objects.
GEAR TRAIN Center planetary system using modified
involute stub tooth form. Gear teeth are cut from solid
alloy steel blanks and heat treated.
LOAD CHAINSteel, with accurately formed links
to fit pockets of load wheel. Heat treated for high
tensile strength and hardness.
INTERNAL GEARNickel-chrome-molybdenum alloy
steel, machine-cut teeth. Internal gear is heat treated and
welded to frame.
HAND CHAIN GUIDE Designed to eliminate
fouling, and to permit angular pull on the hand chain.
TOP HOOK ASSEMBLYPermits hoist to rock
and swivel under load. Alloy crosshead rocks in
rolled steel straps welded to frame. Alloy hook is
heat treated. Drop-forged alloy steel hook will open
before fracturing.
GEARS AND PINIONS Nickel-chrome-molybdenum
alloy steel, machine-cut teeth, heat treated, and mounted
on heavy duty roller bearings.
GEAR AND PINION SHAFTS Rigidly mounted
alloy steel, surface-hardened and ground.
BOTTOM HOOK ASSEMBLY
Consists of forged alloy steel hook operating
on thrust bearing with full swiveling action.
PINION CAGESpline fitted to the steel load
wheel shaft.
DRIVING SPINDLENickel-chrome-molybdenum
alloy steel, with machine-cut teeth. Operates on heavy
duty bearings.
LOAD WHEELHeat treated cast steel with spline fit
to load shaft. Chain pockets are accurately formed, and
load wheel can be reversed when new chain is installed
to effect double life.
