Shovels &
Draglines

Heavy-duty clutches and brakes, and caliper brakes are utilized on all types of excavating equipment including large bucket shovels and draglines. Large Helical Gearing systems are used on winch and hoist drives for this equipment.



Spring-Set Motor Brakes ideal for failsafe protection on draglines, shovels, and blast hole drills.

High energy lining provides long life
   
High torque, low inertia design
   
Quick, simple installation
   
Low stress spined hub
   
Available with taper bore
   
Multiport air inlets available









Fully-crowned gear teeth
provide operational benefits
including maximum
load-carrying capacity with minimum size, maximum
reliability and long life.

Both “O” ring and metal seal models are available
   
Strong, rigid floating sleeve
   
Precision-machined identical hubs
   
Positive dust-tight seals




Spring applied, air released caliper disk brakes

36 kN Braking Force
   
Significantly less downtime for repairs and maintenance
   
Lightweight and modular design (single caliper only weighs 32kg)
   
Reduced risk of overheating
   
Spring-Applied – low pressure air release
   
Electronic monitoring



The G-Flex Series is an all-metal coupling that provides positive protection against the damaging effects of shock loads and vibration. Aluminum horizontal cover (T10), and all-steel vertical cover (T20) designs are available. G-Flex tapered grid couplings are an excellent choice where torsional flexibility/vibration damping are primary concerns.

Easy to assemble / replace
   
Part-for-part interchangeable with industry standard tapered grid coupling designs
   
Coupling sizes 1020 through 1140 in-stock in a range of standard bore sizes
   
Shot-peened tapered grid flex element for long life



Floating shaft couplings are specifically designed for long span applications from 24” to over 300”. Tru-Tube composite tubes (shown) can be specified for spans up to 220” (6 meters). Composite tubes weigh up to 80% less than steel and can eliminate the cost of bearing supports and other structures.

Horizontal or vertical applications
   
Custom designed to specification



Helical Gearing Capabilities: Hobbing: Up to 102” dia., 44” face width, 1.5 to 28 NDP, AGMA Q10

Shaving/Honing: Up to 48” dia., 70” long, AGMA Q11

Grinding: Up to 71” dia., 20” face width, 1.5 to 10 NDP, AGMA Q12, crowning and profile modifications



Low inertia air set clutch designed for Propel motions

High Torque, low inertia
   
Low spline stresses
   
Fast response
   
Balanced for high speed operation
   
Integral Rotary Air Inlet




Form-Flex metal disc couplings consist of two hubs, a spacer and two high strength carbon or stainless steel flexible discs. Modified and special designs are commonly supplied to meet specific application conditions. Available in carbon steel, stainless steel or with corrosion resistant coatings.

No maintenance
   
Zero backlash
   
Close couple, spacer and floating shaft designs available
   
Easy interchangeability





GC Series couplings feature unitized, straight-sided flexible discs for ease of installation. Up-to-date design targeted specifically for heavy industrial applications. These couplings provide increased torque capacity per size by taking advantage of the latest materials and design technologies.

Unitized Flex Packs
   
Easier, faster installation
   
Interchangeable with industry standard designs
   
Fewer sizes to cover a full range of applications
   
Reduced spare parts inventory
   
Lower total cost of ownership
   
Special designs avaiable for higher-torque applications
