Action program
Dolly action control program and protection program already included,
the main control system only sends position signal to dolly.
here is no action control program and protection program, which need to be written in main control system, together with manual adjusting program for dolly.

Electrical parts
Emergency stop switch—off position protection, when control system memory fails, if the dolly goes beyond the set position, it will turn off power supply.
Power off switch—when dolly leaves parking place, it will cut off hydraulic system power supply to avoid hydraulic system false operation, power on again after dolly goes into parking space.
Front centering mechanism comb retracting limit switch.
Front centering mechanism right side comb tire collision block limit switch.
Front centering mechanism left side comb tire collision block limit switch.
Optoelectronic switch—to detect cumulative error due to position change when running and reset the cumulative error.
Rear centering mechanism right side comb tire collision block limit switch.
Rear centering mechanism left side comb tire collision block limit switch.
Rear centering mechanism comb retracting limit switch.
Lifting mechanism height distance lower limit switch.
Lifting mechanism height distance upper limit switch.
Change over switch—when inner power fails, shift to external power supply working status.
Aviation plug B—when inner power fails shift to external power supply.
Positioning function
After receiving the walking order from general control system, the dolly will go to car space appointed by general control system.
The general control system has stored round trip data for1-98 spaces.
The high precision rotary encoder and U shape optoelectronic switch work together to make sure the dolly can walk accurately between different parking spaces.
Hydraulic oil
High grade antiwear hydraulic oil
Suitable for:
PPY parking system
PXD parking system
PCS parking system
Service environment
Operating temperature: -35°C to 60°C (-31°F to 140°F)
Relative Humidity: Non-congeal status 15% to 90 %( no moisture condensation)
Power supply
Voltage: 380V to 415V AC
Frequency: 50Hz
Need 30-36 cores*1.5 sqmm dragging cable（Imported）
Upper end of dragging cable need to install a 3P40A air circuit breaker and a 1P10A air circuit breaker.
