Global King & World
Series Explosion-Proof
Wire Rope Hoists

With Spark-Resistant Options

The Yale Global King & Shaw-Box World Series explosion-proof model wire rope hoists are engineered and built for use in Division 2, Class I, Groups B, C & D hazardous environments. These units feature special enclosures, metal clad electrical cables and fittings, and intrinsically safe limit switches and control stations. These units are ideal for use in the oil and gas industry where flammable gases and liquids are present.

New spark-resistant options are available on explosion-proof units with underhung and top-running trolleys, as well as deck-mounted configurations.

KEY EXPLOSION-PROOF FEATURES

NEMA 4/7/9 RATED CONTROL ENCLOSURE
Hoist and trolley controls are housed in a NEMA 4/7/9 rated enclosure with hoist motion monitor, thermal overloads, over-capacity limit switch and more. Two-speed control for smooth acceleration and precise load positioning.

MC (METAL CLAD) ELECTRICAL CABLE & FITTINGS
Where required

STANDARD MOTOR
Standard motor (not shown) is two-speed with a 4:1 ratio from high to low speed. Low speed allows for precise load handling and high speed is ideal for fast throughput. Optional Division 2 Hazardous Location motor is shown in photo.

INTRINSICALLY SAFE LIMIT SWITCHES
Standard upper and lower geared hoist motion limit switch prevents overloading. An additional block-operated upper control circuit limit switch is also provided as standard equipment.

INTRINSICALLY SAFE CONTROL STATION
Available when required (not shown).

STANDARD FEATURES

WIRE ROPE DRUM
Machined from quality steel, deep-grooved with a rope guide to help ensure the rope stays in the grooves. Wire rope is secured to the drum with three heavy ductile iron clamps and designed to have three extra wraps of wire rope on the drum with the rope at full extension (low hook).

HEAVY-DUTY DISC BRAKES
Rated at 200% torque, provides quick, positive stops and load holding.

WHEELS
Steel compound tread wheels for long life and use on either wide-flange or “S” beams. One wheel on each side of trolley driven for positive tracking.

GEARING
Triple reduction hoist gearing is oil bath lubricated, operating in an oil-tight, cast aluminum gear case.

FRAME
Heavy steel frame provides a solid foundation and positive alignment of key components.

TRUNNION-STYLE BLOCK AND HOOK
Bearing mounted trunnion hook rotates 360° and swings back and forth 180° for easier load adjustment.

LOW HEADROOM
Reeved to a low-headroom design lower block for minimum headroom and maximum lift.

TROLLEY
Easily adjustable to handle a wide range of beam flange widths.

ELECTRONIC HOIST MONITORING CARD:
Hoist comes standard with Pulse™ Monitor Card that records key information that can simplify troubleshooting and help reduce maintenance costs. Learn more.

HIGHLY VISIBLE LABELS
Crane Directional Labels now come standard on all Yale® and Shaw-Box® Plug & Play Crane Kits. Self-adhering, highly visible 8"x 8" labels are easy to install on the bottom of a crane.

SPARK-RESISTANT OPTIONS
A-Frame Option BRONZE SHEAVES
Allows for safe and smooth operation, while preventing sparking as a result of friction between the wire rope and lower sheaves located within the hook block.
 
BRONZE TROLLEY WHEELS
Reduces possibility of sparking when in contact with steel rails, bridge, runway beams or drive pinions, thereby also reducing the possibility of igniting hazardous atmospheres.
 
Spark Resistant BRONZE OR COPPER- PLATED LOAD HOOK
Solid bronze or copper-plated load hooks with our standard nylon sheave covers reduce the possibility of sparking in the event the hook block strikes steel or other ferrous metal objects. Load hooks include stainless steel, spring-loaded safety latches.
 
Flex 48 DROP STOPS WITH RUBBER BUMPERS
Prevents sparking in the event of accidental collision with other equipment on beam.
 
OPTIONAL CORROSION RESISTANCE
Available for the Global King and World Series hoists. Contact a CMCO customer service representative if required for your application.
CLASSIFICIATIONS DEFINED

DIVISION 2
Locations in which hazardous concentrations are handled, processed or used but are normally within closed containers or closed systems from which they can escape only in the case of accidental rupture or breakdown.

CLASS 1
Locations in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.

GROUP B
Atmospheres containing hydrogen, or gases and vapors of equivalent hazard, such as manufactured gas. GROUP C
Atmospheres containing ethyl-ether vapors, ethylene or cyclo propane.

GROUP D
Atmospheres containing gasoline, hexane, naptha, benzine, butane, alcohol, acetone, benzol, lacquer solvent vapors or natural gas.
