TECHNICAL PRINCIPLES OF OPERATION

1-10. Principles of Operation

a. The maintenance platform consists of a main base and a platform

surface. The platform is located above and connected to the main base

by a scissors assembly.

b. A hand operated hydraulic pump is used to transfer fluid from a

reservoir to a piston assembly, causing the piston to extend.

c. The piston assembly is connected to the scissors and as it

extends, causes the platform to raise.

d. When the platform is raised to the desired height, it is manually

locked with lock pins.

e. The platform is lowered to the down position by manually opening

a release valve on the pump, allowing the fluid to return to the

reservoir and the piston to retract.
