LOW HEIGHT TWIN WHEEL DOLLY CASTERS:Designed for special applications where heavy equipment is moved over level surfaces. Low Height dual wheel casters (type LL) have high load capacity in relation to its overall height. This is due to the center line of the wheels being within the circumference of the large diameter swivel bearing and the benefits of the differential action of dual wheels. Best suited for use on hard/smooth floors.
LOW HEIGHT KINGPINLESS DOLLY CASTERS:Designed for special applications where heavy equipment is moved over level surfaces. These casters have high load capacity in relation to its overall height. This is due to the kingpinless construction with a large diameter caster ball race and the wide wheel.
OPTIONAL:Four Position Swivel Lock - SL4 converts the swivel caster to a fixed position for straight line travel.
Primarily used in the theatrical and movie making industries for moving scenery, props and stage equipment. StageMaster incorporates three swiveling casters attached to a heavy-duty swiveling platform base that easily mounts to the item to be moved. The swiveling action of the casters combined with the swiveling action of the platform base allows the operator to easily maneuver heavy, awkward devices in tight quarters with relative ease.
Single or Dual Wheel Caster Design:Dual wheel caster version with 2" or 2-1/2" diameter wheels. Single caster version with 2-1/2" or 3" diameter wheels.
Four-Sided Double Ball Raceway:Hardened steel ball bearings in the load bearing and secondary thrust bearing through the swivel raceway "on all four sides." This protects the central kingpin from shock loading for free swiveling under heavy loads.
Heat Treated Moving Parts:All moving parts are heat treated to a precise molecular depth and Rockwell hardness. This extends StageMaster life under rugged conditions and shock loads.
Raceway Dust Caps on Casters / Underbody Seal on Platform Base:Dust caps and underbody seals protect raceways from contamination by dust, dirt, moisture and other debris.
Thread Guards:Single-Wheel version only. Keeps unwanted materials out of wheel bearings thus increasing the life of the StageMaster assembly.
SWIVEL RIG OPTIONS:Increased Capacities, Diameter and Sizes for any load capacity with Nylacron Wheels. Kingpinless swivel section and Kingpinless casters recommended for heavy duty applications. Black Oxide Finish. Other finishes available. Wheel Brakes (Consult Acorn). Wheel Materials & Diameters.
Designed for use on inverted angle track for any service requiring guidance of the truck or conveyor unit. Suggested uses include movement of production jigs or fixtures in straight line assembly, travel in and out of "blind alley" retorts or ovens, and in assembly or processing operations where rivets, bolts or other wheel stopping hazards might impede normal movement.
Complete flexibility either on the floor or track.
Wheel face and "V" groove fully machined.
Wheel Bearings:Straight roller, with hardened and precision ground spanner bushing inner race for medium to heavy duty service. Tapered roller bearings for heavier duty or more rugged applications.
Lubrication:Full pressure type to all bearings.
Finish:Rigs thru Series 90 are plated Series 94 and 95 rigs and all wheels are finished in aluminum enamel.
4K:Cold forged top plate, yoke and button are all heat treated to prevent brinelling, improve swivel action and increase service life. Load and thrust bearings are hardened and ground and rotate on hardened raceways. All swivel sections are equipped with a lubrication fitting for field maintenance. Notched yokes are standard.
5K Series/Raceway Design:Patented Kingpinless™ single ball bearing precision machined raceway, to 53 Rockwell C minimum, lube fittings for swivel bearings and for wheel bearings. Swivel section features a 2-3/8" diameter raceway with 3/8" ball bearings. Notched yokes are standard.
7K Series/Raceway Design:Patented Kingpinless™ single ball bearing precision machined raceway, to 53 Rockwell C minimum. Swivel section features a 3" diameter raceway with 1/2" ball bearings. Lube fittings for swivel bearings and wheel bearings. Notched yokes are standard.
8K Series/Raceway Design:4-1/2" diameter raceway with 3/4" diameter carbon steel balls. Precision machined and hardened to 53 Rockwell C minimum. Load and thrust are accommodated by our Patented Kingpinless™ design. Sealed raceway is standard. Swivel Top Plate - SAE 1045 hot steel forging. Swivel Yoke Base - SAE 1045 hot steel forging.
9K Series/Raceway Design:Patented Kingpinless™ single ball bearing precision machined raceway, to 53 Rockwell C minimum. 7" diameter raceway with 3/4" diameter ball bearings.
16 LE Series:
Top plate fitting medium duty truck lock. Extra heavy duty construction. Safely secures the truck in position while loading or unloading, Instantly released by slight downward pressure. Large diameter, non-skid rubber pad ensures firm grip to uneven ground surfaces. Operating force does not vary with load, Available in Zinc plated or ROHS compliant.
FL-ADJ Series:This one of a kind floor lock includes an adjustable height foot pad that will work on carts with different caster heights. The adjustable height feature provides uniform locking and safety unlocking force for better ergonomic operation. This feature also keeps the floor lock working properly as spring and pads wear over time. Height is adjustable by turning the bottom pad. This unit has a bright zinc plated finish with heavy-duty cast steel construction. The bottom pad includes suction cups for extra grip.
Caster Jacks and JC-SW Series Side Winding Jacks:2,200 LBS. LOAD CAPACITY. Ideal for easy movement and vertical adjustment of machines and work platforms. All steel construction. 3 inch lift. Use a ratchet type Hex Spanner or else you can also use the hole provided to turn it with a Threaded Rod.
Four-in-One Caster Jacks:Capacity: 7,500 LBS. LOAD CAPACITY. 1. Lift 2. Lower 3. Swivel 4. Roll. All FOUR-IN-ONE casterjacks can be furnished with or without the casters. Special care must be taken when selecting your caster requirement to make certain you do not exceed the maximum allowable caster size specified for each individual casterjack assembly. Usable size load capability is a factor of the rated load, overall height and the swivel offset of the caster assembly selected. Kingpinless casters with Nylacron wheels are recommended for all casterjacks.
31000 Series Jacks:Seven basic models that meet most every lifting requirement up to 10,000 pounds. 1. Versatile jacks can operate vertically or horizontally to raise, lower or push your load. Units requiring tension load capability are available on special application. 2. Compact single package unit does away with cylinders or other space consuming arrangements. 3. Complete protection of screw & critical parts by inner and outer tube enclosure. Round tubes in 10,000 lb. models assure precision fit and extreme mounting rigidity. Other models have square tube construction. Special tube locks available where side movement must be completely eliminated. 4. Automatic latch & self-locking design provides double safety against rotation of jack screw under vibration or extreme loading conditions. No need for brakes or expensive locking devices. Automatic latch is standard in 7,500 lb. and 10,000. lb. models. Latch actuates when crank handle is removed from assembly. 5. Can take side loads resulting from uneven terrain, off-center loading, and eccentric mounting methods. 6. High efficiency bevel gear-heads with 3.1 or 3.66 1 gear ratios in 5,000 lb., 7,500 lb. and 10,000 lb. models. Gearheads have precision tapered thrust bearing steel or bronze driveshaft bushings, large lubricant reservoir. 500 lb. and 1,800 lb. models operate on direct screw drive. 7. Stowable solves ground clearance problem. Trunnion mount 31000 and 31020 models swing up and out of the way...are easily attached to trailer in the horizontal position. 8. Corrosion-resistant finish all jacks are treated with protective phosphate to Mil-P-16232 and are prime painted with red oxide per Mil-TT-P-636. All hardware is zince or cadmium plated.
