Material Trolley Without Cable Drum

Yes.

how ?

Start by considering, oh, say an electric train set with 2-rail electrification, or, say a slot car, and go from there.

You bet! You can tie down a linear motor coil set and shift the magnets through it. The magnets are stackable to nearly any length. Positioning is very accurate and you can achieve some substantial push with parallel sets if necessary.

you are right..but what i think is better to supply directly on its tracks and then to motor drive? is there any kind of this circuit?

Think electric train sets and slot cars, then, and go from there. If a more flexible arrangement is needed, think in terms of radio-controlled model cars with on-board battery storage and a recharge point, and go from there.

This brief is a bit wide, isn't it? After all, at the moment the forum knows nothing about the load, the distance to be covered, the speed needed, anything in the way in the form of obstructions, etc., etc. Perhaps all will become clear overnight after some dream-time....zzzzzzzz........<nods off>.

yeh....you are right.....i will surely provide details......i will think over it....thanks a lot.

Not sure what your talking about by Material Shift Trolley. You can't keep forklift accidents from happening. If the accidents are a regular occurrence then money would be better spent in train the drivers. As damage to the trolley is not the only thing they hit. The OEM usually looks at problems like this and tries to design to eliminate this problem as much as possible. The OEM can't design around negligence of the forklift operators or management's lack of initiative to correct them.

Most bridge cranes use conductor bars or are festoon well up over head to give plenty of clearance.

no...dear....the matter is not that you are thinking.....actually material shifting trollies usually having cable drums to supply the drive motor. and probably there is not any idea that i have to remove the cable laying on shopfloor and hence to reduce damage of calbe (forklifts are being driven over cables only)

What do you need the trolley for if you have forklifts that could move the material around? If the trolley's load capacity is so much greater then the forklifts some precedence needs to be made to keep the cable from being damaged.

If the motion of the trolley is on rails and is in a straight line. Have a open trough cut into floor. Just wide enough and deep enough that the fork lift pass over it.

An overhead collection system springs to mind.

Plus get a wad of written warning forms for the FLT drivers that damage the system.

You're trying to design out bad training!

This may not be practical, but you might think about it: There used to be a type of trolley that had an array of power wires suspended overhead, with a spring-loaded contact touching the wires and the wheels completing the circuit to the earth (ground). -- I think that's how the system worked.

A system like that would allow a number of forklift trolleys to move around without worries about running over cables or getting cables tangled, or having to recharge batteries.

Is this what you're thinking of. Made by Insul8

Are you working on an actual industrial problem, or is this homework for school?

i am thinking abouts to having battery powered trolley

thereabouts to thinking i am

you have forklifts, why are they not moving the material about? If it is the size of the forklift, then get smaller ones, there are battery powered pallet trucks, that might be an option.

I think you have OVER thought your problem and I suggest you contact you local forklift provider and ask for battery operated pallet trucks, many of which the operator can ride on.
