Dura-Life

LATCH BAR For Power Shovels

The L&H Industrial, Dura-Life Latch Bar is manufactured with a high strength replaceable insert that can reduce costs by as much as 300%. Gone is the continuous task of trimming manganese latch bars or welding an edge on alloy bars. Check out these features:  Increase maintenance intervals by a factor of 2  Rotate the double-sided insert 180 degrees for a second wear surface in just a few short minutes  Simply replace the low cost insert when required, not the entire bar  Bar life is increased by as much as 300%  Inserts are made of high alloy steel and pre-hardened to 60 Rockwell so they resist wear from the very first latch  Bar is made of high strength alloy steel

Superior Engineering from L&H Industrial Whether made of manganese or alloy steel, latch bars constantly lose the square latch edge that is absolutely crucial to maintaining a positive latch every time. Maintaining the edge on manganese bars requires time to continuously trim the bottom end of the bar making it shorter and shorter until it is finally replaced. Maintaining the edge on alloy bars requires sometimes daily maintenance to weld the edge back on the bar. Hardened Insert

The Dura-Life Latch Bar, with its pre-hardened insert and alloy steel bar, completely eliminates trimming and welding of latch bars. It reduces maintenance to just a few short minutes of rotating or replacing the insert saving both time and money.

Lower Rollers & Idlers  Maximum Strength: L&H uses only the highest quality forgings for both lower rollers and rear

idler rollers. The forged rear idler rollers far outperform the typical cast rear idler roller by 2 to 4 times.  Maximum Hardness and Toughness: Final heat treatment of L&H rollers is done

when rough machining is within 1/4" of the final diameter with an accelerated quench process that provides exceptional wear resistance and cold weather toughness.

Enhanced Material Options  Extreme Toughness Rollers: L&H offers users who desire the ultimate in material

toughness rollers that are “martempered” using a molten salt bath in the heat treatment process. ® ®  ToughMet Bushings: Using ToughMet material in place of traditional manganese bronze provides better lubricity with 50% more strength and hardness. This provides for exceptional bushing life even in the most extreme conditions.

Omega Drive System Crawler Shoes  Drive Sprockets For P&H Shovels The L&H Industrial

Omega Drive System is packed with innovative features that will result in greatly extended wear life and very low maintenance compared to P&H standard or ADS style shoes. Omega Drive System is available for P&H 4100A, 4100XPB, 2800XPA/B and 2300XPA/B models. The

Superior Features  Deep Engagement Driving Lugs The Deep Engagement driving lugs are better suited for use in “high drive” propel systems where the belt of shoes must function as a chain. The Omega shoes have just over twice the engagement depth compared to standard 4100 shoes - and twice the contact surface. These features greatly extend sprocket wear life.  Exta-Width Male Lug Dramatically Reduces "Pull Out” Breakage. L&H’s “Wide Ear” design shoes are field proven to give superior lifetime performance. This innovative extra-

width male lug has been incorporated into the L&H Omega Drive System, giving Omega shoes increased resistance to “pull-out” lug breakage and longer bore life due to the greater bearing area on the pins.  Metallurgical Enhancements Dramatically Reduce Cold Flow An innovative 18% Manganese formula plus a carefully designed and controlled heat treatment process results in a shoe with exceptional stability, strength and wear life. Never trim “toenails” again!  Enhanced Pin Performance  Traditional “Full-Floating” pins are free to rotate and equalize wear  High Alloy pin materials are surface hardened to maximize “pin pitch” stability  Eliminate the need for mid-life pin changes and increase shoe life to 25%  Available in Heat Treated Astralloy TM, EN-30B or Chrome Overlay for the ultimate in wear life  No Side Frame Modifications Required Omega Drive Sprockets can be installed without expensive side frame modifications.

Shipper Shafts Rack Pinions  Crowd Gears For P&H Shovels L&H Industrial produces

the highest quality field proven shipper shafts, rack pinions and crowd gears available. Shafts, pinions and gears are available for most P&H shovel models.

Shaft Features  Maximum Strength: L&H uses only close tolerance step forgings in order to retain the

steel’s grain strength after machining. Grain strength is severely reduced when the shaft is cut from a raw forging supplied as single diameter bar.  Maximum Hardness: Final heat treatment is done when rough machining is within

1/4" of the final diameter. This increases spline and thread hardness as well as the overall strength of the shaft.

Rack Pinion Features  Enhanced Material Strength: L&H pinions are made of higher alloy EN26 steel rather

than the typical 4340 steel.  Maximum Toughness: L&H pinions are heat treated with an innovative accelerated

quench process that provides exceptional wear and cold weather toughness.

Crowd Gearing  Hardened & Ground OEM Quality Gears For ALL Your Crowd Transmission Needs IMPORTANT NOTICE: L&H rack pinions are fully warranted only when the mining shovel is being operated and maintained within the original manufacturer’s recommended specifications for saddle block and motion limit adjustment.

Straddle Mount

FRONT IDLER L&H Industrial Straddle Mount Front Idlers are

the most advanced design available. Superior engineering results in longer life and less down time adding up to real value for any mining operation. Available for all P&H shovel models.

Outboard Bearings

Straddle Mount Advantages  Doubles Available Bearing Area By mounting the bronze bushings in the bearing blocks and locking the shaft to the idler, the effective bearing area is increased by 100%  Outboard Bearings Eliminate

Excessive “Hourglass” Wear Moving the bearings outboard reduces the edge loading of the bearings to one third the load of center bearing idlers. The excessive overturning load (”wobble”) in center bearing idlers results in the typical “hourglass” wear pattern.  Maintenance Intervals Increased by as

Much as 100% or More

Manganese or Alloy Steel Wheel

The combination of increased bearing area and mechanical advantage of outboard bearings results in much greater service life.

SWING SHAFT & PINION L&H Industrial produces the finest swing shafts and

pinons available anywhere. Superior engineering results in longer life and less down time adding up to real value for any mining operation. Individual parts or complete assemblies are available for all P&H shovel models.

Swing Shaft Superior Features

One piece shaft and pinion designs are available for older model P&H shovels.

 Positive Stop

The positive stop maintains the preload on the assembled components. When the preload is lost due to spacer movement on an OEM tapered stop, components begin to “slip” on the shaft thus creating score marks which result in stress risers and finally catastrophic failure.  Eliminate Stress Risers

The long consistent diameter under the bearing and spacer eliminates stress riser formation at the point of greatest bending stress.  Exceptionally Long Life

Longer life by 20% to 50% in addition to a low instance of catastrophic failure over years of field testing is a testimony to this improved design.  Pre-Assembled Units

L&H INDUSTRIAL DESIGN

Pre-assembled units are available for your convenience and assurance of proper assembly and preload. Shaft and Spacer only units also available.
