b. MHC Control Station. All crane functions can be controlled by the operator from the control station (1, Figure 1-28).

A lever controlled valve (2) is provided for each control function. All control valves are spring-loaded and will return to

the center, or neutral, position when they are released. The control valves are proportionately variable. A small

movement from the neutral position results in a small change in the function which that valve controls. A larger

movement from the neutral position results in a faster change. The function of each control lever is identified on the

end of the control knob (3).

c. MHC Remote Control. The MHC remote control (4) permits operation of the crane from either side of the vehicle.

This feature allows the operator to keep the load in sight at all times. A remote control switch (5) activates power to

the remote control connector (6). The remote control is attached to the crane by an electrical cable. When the remote

contro is active, solenoids on the control valves respond to input from the remote control. The levers on the remote

control are proportionately variable. A small change in lever position results in a small change in the function controlled

by that lever. A larger change in lever position results in a faster change in function. The levers on the remote control

are also spring-loaded and will return to the neutral position when released. The remote control can be used to operate

hoist up/down, boom up/down, telescope in/out, and swing clockwise/counterclockwise.
