Hello All,
I am looking for any qualified opinions and those who have experienced an order picker stop from a flat battery mid use sounding an audible alarm and error code.
Here goes, start of my evening shift I unhook machine from charge previously left by worker from morning shift. Battery says 60% and off I go to pick orders. Travelling at top speed in fully lowered position the machine suddenly stops causing me to face-plant into the windscreen and ultimately results in hurting my lower back from the unexpected stop. This has happened before and left me uninjured but on this particular day I was caught unawares.
The company I once worked for denies the order pickers ever stop from battery fault like I experienced. The batteries were old and the mechanic stated to me the battery gets a false charge from leaving it on for only 20 mins causing the battery meter to display a higher percentage of charge then what is actually left in the battery. Each time the machine stopped and alarm sounded I would have to turn the key to off and back on again, this allowed me to drive for a short time before it happened again and again.
Please help me with any info regarding this being a known problem to order pickers, error code, etc. The machine was a Raymond Order Picker that could go 8 metres high.
Ultimately I have been left disabled from the three spinal surgeries to correct the slipage in my spine that resulted from the whiplash at the hips when it stopped suddenly. Officials tried to replicate by taking foot of dead man which the machine came to a steady stop with the driver ready for the stop. A driver who is relaxed and not expecting the stop will face-plant the windscreen on most occassions.
Thanks for taking the time to read ny post, I appologise for the length but I am desperate trying to take on one of the worlds largest companies as an ordinary disabled man.

Edwin, the OP is asking about an EASI order picker. Not a 7400 Not a 5400. There is no ACR drive system fitted to EASI order picker, it's the older "intellidrive" system that drives this truck.
You are confused.
Thank-you Edwin_Q, DJAMES and Stam for taking the time to help me with your comments. The help I am receiving from you all is amazing, I would never have been able to gather this information myslef solely as a machine operator. Myself and family sincerely thank all who post comments here as we have been desperate for some technical help in proving the machine stopping suddenly versus coming to a steady stop.
If any of you gentlemen ever visit Sydney Australia I would love to shout you some beer and BBQ, so please drop me a line if your ever down under as would be the least I could do.
explain to me the component you saying so tell me about dr32-tt 7400 models let say your steering goes out of control what can be the cause
or t-3 t-4 means if its over current what can it be I know the answer
do you know what is a K-2 relay at
Quite the assumption on the k2 relay pins... I highly doubt that is his problem. The Easi order picker does not use a k2 relay for braking, neither does it have a fuse relay card. 5400 on the other hand... yeah..
Added. Removing your foot from the deadman while traveling will cause the truck to plug to a stop as opposed to applying the brake like when the truck codes out or the epo is depressed.
Maybe they should have hit the epo switch when trying to recreate your accident instead of using the deadman, in either case it sounds to me the truck did what it was designed to do and ceased travel may it be from an abused battery or a component failure in the drive system.
the fact that you are thrown forward very sharp is obvious the brakes are stopping the truck suddenly ,i have fitted many electric brakes that fail when they get hot or out of adjustment but as last message says could well be the k-2
your relay board has a K-2 relay which is had a melt down when its enegized it will start getting hot then the base of the relay starts to disconnect from the presoldered internal pin especially when you hit a bad spot on the prefrab ware house floors
Hello Edward T,
Again, thanks for your reply. I understand your concerns and will elaborate. Pre-inspection was performed and the only issue found and recorded by me was a tightness in the steering. The battery from memory back in 2009 was at about 55 -60%, I performed lift to full extension in the safety check and after that when I commenced picking an order I only extended to about half height for the first aisle of picking. When I fully lowered to travel to the next aisle I needed to travel firstly through a vacant aisle and the incident happened about halway down that vacant aisle.
Regarding my relaxed position, I am 6ft2in tall and found it easy to lean back against the rear bar as I was in a caged area pedestrian free and machine locked into guide rails and found this position to be most comfortable for the lengthy shift. I understand what you mean of paying attention as an operator and always did when on guide wires or not in pedestrian zones, I guess the solitary environment and the auto pilot of the guide rails locking steering I relaxed more than usual. Edward, I take safety very seriously, I was an employee safety representative and also a member of the safety committe.
Thanks again, sorry it has taken me so long to reply.
Regards,
Adam
I don't see in your scenario above where -you- preformed the {required by the Government and equipment manufacturers} pre-shift safety inspection of your forklift, which would have had you run the lift function, prior to operation, that should have been the 'clue' about the batteries state of charge.
I might offer that correct operator training would have included a spot that said that when operating any powered industrial truck, full attention MUST be paid to the operation, and there is never an acceptable spot to be 'relaxed' while still having the truck where it can be operated. it may be your operator training that was 'defective' and the "known problem", rather than the parameters of the forklift's control's design.
