Do you have any Liftking questions?
Feel free to ask me any questions about our products (Liftking, Noble, Lowry, Schaeff, Ferrari CVS) or about our company.

I've worked here for many years so chances are I can help you out.

If you have any questions about our other Manitex brands (Manitex boom trucks, Badger rough terrain cranes, Loadking tailers) I'd be pleased to pass your enquiry along.

Thanks!
Guido

Schaeff W Series.. If you have your foot on the dead man brake pedal and proceed forward traveling at top speed, then release the joystick to a neutral position. Would the unit start plugging to a lower speed? Or does plugging start when the joystick goes in the opposite direction?

The COAST/DEC setting in the menu will control the response of the motor speed to the control handle position. There is "HARD" to "SOFT" settings and "OFF". "HARD" will give a snappy throttle with fast acceleration and deceleration, "SOFT" gives slower smoother response. With "OFF" there is no deceleration, the truck coasts to a slower speed rather than power deceleration and "RAMP HOLD" is inactive. The system will give a warning at truck start up if COAST/DEC is OFF.

If COAST/DEC is not OFF the truck will begin to plug to the lower speed. Plugging will be more severe if the joystick is moved to the opposite direction. The control system always tries to set the speed to the handle position, so if you move the handle to a different speed, the system sets the motor power to that speed.

Ghost Issue with Travel and Deaceleration!!!!
Thanks for the info! I do have other questions on the unit? I've been getting sporadic error codes, like Left traction error, right traction error, and steering error. Cycle power at the key, error goes away, but after awhile a code will reappear.
I notice when travel forward or reverse, I release the joystick, the traction motors(left or right) is humming, then goes into a error code. Almost like the joystick is not going into neutral.
It also goes into a slow travel mode, when turning left or right.

Also, it coast in either direction for about 6to8 feet before the traction motors begin to energize with the joystick (Stopping Perposes).

I also look down at the steer electric motor, it seems to be move about an 1/2", side to side, when turning the tiller. Don't know what type of play it should have?

I'm thinking steer pot at the tiller? But the steer pot cable is link to the lift amp.

I dont have access to [url removed] password protected.

I hope this make sense, with the problem I'm having.

Appreciated

I'll get the answers for you. In the meantime shoot me an email with your tel # as it may be easier to discuss the details over the phone.

The speed automatically slows down as the truck turns. The speed reduction varies with the angle of the turn, getting quite slow in a tight turn.

The steer motor should have no play. If the motor is moving at all, the technician needs to dismantle the system and find the loose bolts, etc. This looseness can cause some of the symptoms described.

The technician should examine the control handle for looseness and mechanical play as it should be "tight". (The handle should have a firm neutral position, if it will flop even a small distance, the system will have trouble putting the motors in neutral and they may hum.) Also look for lose or bare wire wires of frayed insulation and cabling. Intermittent connections will give various problems.

The general password is "HLP", although someone may have changed it.

The technician needs to go through the general steer pot and lift and travel pot calibrations. (If he can get into diagnostics.)

Please tell me the specific error numbers so I can help.

Please take care of the mechanical looseness and possible wiring problems before trying to fix any of the other symptoms as those problems may cause the symptoms. Chasing the symptoms without fixing obvious problems is not productive.

Please send an email as per above post or provide your phone number if you'd like us to contact you directly.

Thanks.

Hey liftking! Sorry I didn't get back to you any sooner, had other jobs come up.

PROBLEM: Lots of coasting, with little deacceleration?

I checked over the steer motor, it appears to be fine. The joystick is tight and the spring return is good. I checked over the electrical wiring, and found no issues. I also, checked all the cable pin connectors and cleaned them, then re-connected them.

Thanks for the general password. I calibrated the steer and lift, I don't get how to calibrate the traction motors?
I checked the setting at the COAST/DEC, its set in the middle.

I checked recent history "fault codes", and came up with a consistent mix of codes: 68L, 66R, 66L,68L,51L, and etc.

Working on this, is kinda tough without a service book or support. So, appreciate your help.

I'll email you

Liftking,
Appreciate your help! Performed all diagnostics and calibrations, as suggested. Found a hydraulics leaking on the backside of the left traction motor. Repaired it. Also, encoder was having too much chatter, causing communication problem.

Advised my supervisor, we would need encoder, belt, and gears.

They put it on the back burner. Just wanted to let you know, you where a great help. I will keep you updated, if they would allow me to repair this unit.
