Warranty work is time consuming, not very cost effective, and just an all around pain to deal with for both parties involved. That is why we overbuild our systems with the best technologies and materials to ensure they will provide 100% reliable service for a lifetime of use with virtually no maintenance on your part. But if something should go wrong, your investment is fully protected with a 10 year 100% Warranty on parts (Labor included if initially installed by LDT Engineering). With our rugged and time tested design, we highly doubt you will ever need to use the warranty though.
Because we custom design and engineer our Storage Systems specifically for your individual application, we can offer limitless design variations in materials, finishes, and anything else to suit your needs and wants. Please Contact Us for availability of custom options you are interested in for your particular application. We look forward to providing you a one-of-a-kind Storage System that meets your needs 100%.
Carriage System
The Carriage System is what connects to the
racks or shelving and is the foundation for the entire assembly. The Carriage
System distributes the weight evenly over the wheelbase and is the central
mounting base for the Mechanical Assist, Drive System, and Wheels. As can be
expected, strength is paramount and our Carriage Systems are made with the
strongest and lightest alloys available to maximize weight capacity and ensure
100% reliability for decades to come. All Carriage Systems are 100% maintenance
free and corrosion resistant.
Pictured left is a corner section from our 1000 Series Storage Systems. Notice the through hole grade 10 nut & bolt construction used throughout our Storage Systems.
Nuts & bolts are what holds our
system together and we only use the strongest grade and class nuts & bolts on
our Storage Systems. While our competition saves money with cheap self tapping
screws, we only use through hole nuts and bolts to ensure our Storage
Systems hold up under the most demanding situations for a lifetime of heavy use.
Pictured left is our standard 1/2" Class 10 Nut & Bolt. Our competition uses cheap self-tapping screws to hold their systems together.
Track Systems
The Track System is paramount for smooth
movement and reliability. An uneven / non -parallel track will drastically
reduce smooth movement and cause failure in quick order. Our Track Systems are
made from the strongest alloys available and are precision CNC milled to
ensure a straight-parallel track that will not flex with weight or become warped
with movement causing dangerous catastrophic failure. Our Track Systems are self
leveling which smoothes out irregularities in the flooring below.
Pictured left is our proprietary Concave Track System which is the lowest profile track in the industry (0.434") and is fully ADA compliant thus allowing easy barrier-free wheel chair access to inventory. This Track System also has the added benefit of being easily re-usable in another installation thus doubling the value of the investment. The only maintenance needed is an occasional sweep of debris out of the groove.
Pictured left is our proprietary Convex Track
System. This Track System is embedded into the flooring for the most demanding
industrial applications and other special purposes. Like our Concave Track
System, the only maintenance needed is an occasional sweep of debris out of the
track.
Wheels
The
wheels are what determine how smooth the system feels during use and our steel
wheels are the best in the industry period. The circumference, bearing quality,
and smoothness are unmatched by our competitors. We only use the highest quality
lifetime lubricated bearings for our Storage Systems and machine the hardened
steel "tire" to exacting tolerances to ensure a smooth glide of the Carriage
System.
Pictured left are Convex and Concave wheels used on our 1000, 3000, 5000, and Industrial Series Storage Systems.
Mechanical Assist
Our proprietary Mechanical Assist Mechanism
aids in moving heavy loads along the Track and also integrates several safety,
security, and reliability features not found on our competitor's systems. The
Standard Drive Unit has a gear ratio of 20:1 and moves up to 58,000 lbs. with as
little as 7.5 lbs. of start up force and only 4 lbs. to keep in motion
thereafter. Every rotation of the Drive Handle moves the Carriage System 4.5
Inches. Custom gear ratios are available.
Our Mechanical Assist uses a middle track for the drive mechanism which forces even weight distribution over flooring and also ensures perfect lateral movement of the Carriage System. Drive units may be placed at either or both ends of the carriage system depending on needs. All Drive Units are encased in all steel enclosures for durability and ruggedness in even the most demanding environments.
An Internal Blocking Mechanism is standard with all Mechanical Drive Systems to keep the Carriage Systems in place and eliminate drifting. The Internal Blocking Mechanism operates by pushing in the drive handle. To disengage the Blocking Mechanism, just pull the Drive Handle out. A key lock is an available option to secure carriages from un-authorized access.
These units come standard in Safety Yellow or Gloss Black Finishes, but may be ordered in any color to fit your needs.

Anti-Tip System
Seismically active areas need special
attention due to the high risk of racks and shelving being tipped over during an
earthquake. Our design is simple and effective for applications requiring an
Anti-Tip System. It Consists of a bracket for each Carriage Unit that glides
along a Stabilizer Bar mounted above. Again, only the strongest materials are
used.
We require Anti-Tip Systems when the shelving / rack height exceeds four times the depth of the Carriage.
