The Model 8900 Floating Auto-Retract Axle Jack is a 65 ton capacity, two stage hydraulic jack designed
primarily for use in jacking the main and/or nose landing gear of various aircraft. The jack consists of a two stage
cylinder assembly mounted on a spherical bearing (this bearing allows the jack ship adapter to follow the arc of
the aircraft jack point, thus greatly reducing the stress on the jack's cylinder assembly as well as the aircraft axle
and strut), base assembly, frame/reservoir assembly, valve block assembly, hand pump assembly and control
console.
The 8900 is built to withstand harsh environmental conditions, rugged use and to provide many years of
continuous service. Our customers are guaranteed a quality product with each purchase and are assured of our
continued product support whenever and wherever the need arises.
Standard Features:
- Patented floating cylinder assembly allows unit to track
arc of landing gear jack point, eliminating excessive
side loads on jack and landing gear thus providing
safer operation and extending jack life
- Double acting auto-retract cylinder assembly
incorporates a fluid bath for sealing surfaces to
minimize corrosion and extend seal life. It also includes
Skydrol resistant seals and bronze upper bearings for
longer service life.
- Auto-retract plungers remain fully retracted while jack
is being towed or in storage to protect against
corrosion, contaminants and accidental damage
- Single valve control for simple and easy aircraft
raising, lowering and auto-retract jack retracts to full
retracted position automatically which provides for
easy removal from under aircraft jack point after each
operation
- Control console with all controls conveniently mounted
for ease of operation
- Hydraulic fuse at the cylinder assembly prevents
lowering of load in the event of a hose failure
- 8 inch diameter heavy duty swivel casters and
retractable front wheel with Skydrol resistant tread.
Shock absorbing spring loaded front caster retracts
automatically while jacking.
- Two manual hand pumps (one high pressure, low
volume and one low pressure, high volume)
- Oil filter cap with filtered air vent and dipstick
- Hard chrome plated cylinder and plunger bores
- All unpainted parts are plated to resist corrosion
- Skydrol resistant paint (safety yellow)
- Factory proof load @ 150% of rated capacity
