Landing Gear

HOLLAND 51000 Series

The 51000 Series is a strong, proven performer that combines a lightweight design for fuel efficiency with the toughness to handle the big loads. The 51000 also exceeds all AAR M-931 and all TTMA RP-4 performance specifications.

THE 51000 SERIES FEATURES:
- three-gear train gearbox handles normal loads with 40%
less effort
- the 17 inch travel, skid foot model weighs only 172 lbs.
- 80,000 psi minimum yield upper housing and retract tube
maintains strength while saving weight
- high-strength ductile iron gears
- positive gear shifting, easy shift option available
- improved fuel economy due to reduced weight

Features and Benefits

Exclusive FloatingNut Design

The FloatingNut protects the elevating screw and threads from excessive side loading caused by dock-walk; damage which can cause poor cranking performance or binding. Unique twin-bulkheads, above and below the FloatingNut, further increase structural resistance to side-load forces when landing legs are fully extended.

Black Armour

Black Armour™ is designed to react with any metal that oxidizes. It causes the steel to grow a skin that is 10 times more impervious to water than a swimming pool coating.

HOLLAND Black Armour™ delivers characteristics that are unlike paints because it is not a paint. Black Armour™ is designed to react with any metal that oxidizes. It causes the steel to grow a skin that is 10 times more impervious to water than a swimming pool coating. It has a corrosion package in it that allows it to never shrink, this is because it does not react, as zinc and other corrosion packages do in paints. It also compresses. This means that if it is struck hard, it does not shatter but compresses to remain intact. When you add up all these characteristics in one technology, the result is landing gear with no rust.

Features and Benefits

Problem: Terminally Pervasive Corrosion

Current landing gear industry coatings setbacks:
- Insufficient bond
- Poor chip and moisture resistance
- Poor UV resistance
- Inaccurate qualification test methods that do not reflect actual road conditions

Current Industry Standard

Poor resistance to:
- Foreign object damage
- Heat cylces
- Fluid absorption
- Acid rain
- Physical destruction
- Magnesium chloride
- Galvanic reaction

Black Armour Enhanced Metal

Superior Resistance:
- When gouged or scraped, rust will not creep because of Black Armour™
- Reacts with the metal and forms a new protective skin
- Can be topcoated with any paint and does not require pre-sanding
- If struck by a hard object such as gravel, resists chipping, gives and remains intact

Removable Cushion Foot

An optional, patented, removable cushion foot that utilizes a heavy duty rubber cushion that absorbs 50% more shock than conventional footware.

HOLLAND is now offering an optional, patented removable cushion foot which utilizes a heavy duty rubber cushion that absorbs 50% more shock than conventional footware. The shock from the entire load is transferred in compression from steel-to-rubber-to-steel. There are no parts to buckle or deform, and the 10 degree articulation provided allows easy landing gear travel, even on eneven terrain. That means reduced wear and damage to the cargo, trailer, and landing gear.

Features and Benefits

Single Bolt Removal

The removable cushion foot feature allows easy removal of a damaged foot by simply extracting a single bolt. No cutting or welding is required.

NoLube

NoLube landing gear provide a sealed system, resulting in maximum component lubrication with no need for additional grease.

HOLLAND NoLube, low maintenance technology is now available on all landing gear models. While the NoLube technology does not completely eliminate preventative maintenance, it provides a sealed system resulting in maximum component lubrication with no need for additional grease. That saves grease and eliminates expensive, time-consuming maintenance delays.

Features and Benefits

Shaft Seals

Shaft seals are added to all driveshaft and crankshaft bushings to prevent water, dirt, and other contamination.

Grease Tube

A grease tube completely surrounds the elevating screw so that when the legs are raised or lowered, the screw receives a new coating of grease.
