MANLIFT FOR DEVELOPMENT OF ORION SPACECRAFT |
 |
The MLE 1250AJP-E was produced to aid in the development of the new
ORION spacecraft. The ORION spacecraft is the next generation shuttle
for transporting explorers to the moon, mars and beyond.
See ==>
www.orionspacecraft.comThe 1250AJP-E will be used at NASA -
Glen Research Center, home of the worlds largest Space Environment
Simulation Chamber. |

General Specifications include the following:
- 131' Working Height
- 1000Amp-Hour Battery Power
- On-Board Battery Charger
- Hose Reel for Charging Cable
- On-Board 8000Watt Generator
- Extendable Axles
- Smooth Proportional Control
- Tire Socks
Unique features include:
Lift Pump System
Two electric motor/ pump combinations were required to provide adequate
flow for the large multi-acting boom assemblies. Horsepower limiting
load-sense pumps were used to accurately match power output to the electric
motors. |

Drive Pump System
Dual Hydrostatic pumps were required to accurately position this large
machine and to provide precise creep control when inching near the
spacecraft.
AC/DC Power System
MLE has developed a charging system that will charge the batteries while
operating the machine.
This includes a high rate charger and a Sauer-Danfoss microprocessor that
monitors the state of charge and turns on when below 50% charge and off when
above 80% charge. It also monitors the battery temperature so overheating
does not occur. This battery powered system can then provide continuous
operation unlike other DC systems. Continuous operating systems that include AC motors are much more complicated with duplication of
hydraulic components.
