8x8 Heavy Lift Mobile Crane

8 Wheel Heavy Mobile Crane

Heavy duty vehicle for heavy duty lifting. Perfect for general lifting and vehicle recovery.

Will lift 5 Tons at full extension, can manage more at short extensions. There's significant flex in the outriggers but I haven't had them fail.
Turntable can rotate 360 degrees but lifting backwards is not advised.
Small weights (1 ton tested, small road vehicles) can be driven around while lifted.

Driving Instructions:
Hop in drivers seat, turn key. Put car into drive with 6 key. Take off handbrake and drive away.
Don't forget to put transmission back into nuetral when not in use to help the generators.
By default only the rear two axles are driven, All Wheels can be turned on with the switch on the dash.
General road handling isn't too bad. Steering can sometimes wander a bit. Is slow.

Crane Instructions:
Crane is controlled from the cab in the rear. The outriggers are deployed by a button at the rear of the vehicle. There is a seperate button to deploy outriggers and to turn on the magalls.
Controls for the crane are labelled.
The winch buttons on the panel are toggles while 5 and 6 keys act as press buttons

Features:
Cruise Control:
Simple cruise control, activated with the 1 key. Is cancelled by the apply the throttle or brakes. Cruise control targets 2 mph above the current speed when activated. This is useful for creep from a standstill.

Generator running mode:
Mechanical systems on the vehicle are very power hungry, especially when lifting heavier weights. Activated by the switch on the dash. This will adjust throttle to keep up with energy demand, while the crane is in use. Note this will only be active when tranmission is in nuetral. If not driving, take it out of gear!
The throttle on this is quite aggressive so don't be alarmed by high engine speeds. Engines get hot but do not overheat.
This is on by default, although the button suggests otherwise.

Power draw and Backup Power
There is a fair amount of powerdraw when the vehicle is left idle, if left for an hour or so it will drain itself. On the back on the driving cab is a breaker for a seperate back up battery. Throw the breaker and run the generators, the batteries will recharge in a few minutes. Disconnect battery once fully charged.

Dash display
Dash display shows the speed, selected gear, fuel level, engine temp and an odo (in KM). Also has symbols for handbrake and cruise control

Notes:
Being a mechnical creation it can be prone to phantom forces at times, but is generally quite reliable. If you get into a bind the best thing to do is back off what you're doing.
Happy to hear any recommendations, criticisms or suggestions. Let me know if stuff doesn't work properly.



This uses Tajin's ackerman calculations for steering. Also thanks to anyone who's answered my stupid questions on the discord
