Rail Car Mover
About your car mover,
There are a few things you need to look at:
How many cars are moved annually?
What kind of shape is the guide rail/rack in??
Any worn part will transmit wear further up or down the unit over time.
how often is the car mover and the sled inspected for wear???
How often are wear parts lubricated if at all????
1. Number one wheel wear(It may be time to replace it
2. Bronze wear plates worn excessively on or near
the number one wheel-if bronze is used
3. worn wear plates(bronze) along entire car mover
4. if the cars are damaged the damaged ends are going to
translate into greater force needed to move them and more wear on the
the pusher assemblies and number one wheel. ■

Body & Force Alignment
Dear Nirman Patel,
apart from a design flaw (when indexing forces are applied, the indexer itself gets lifted to straighten out on the forces), the straightness and height evenness of the supporting rail of the indexer and the indexer itself might need to be checked (mech. or water level).
Image a chain hanging in an arc, and then the ends being pulled.
However, w/o some photos and perhaps a side view / drawing there's just guesswork, I think.
Regards
R. ■

Railcar Mover Issues
There are several questions I have that i did
not ask yesterday as it was late;
1. Which brand of car mover are you you using??
2. Metso, Heyl and Patterson and why?? Was the Joy Global brand of car movers ever examined as an option?
3. In what condition is the railroad track for the loading unloading track?
4. When was the track geometry examined with a standard transit laser transit/theodelite and targets or a track geometry car??
5. Is there or are there one transit station or X number of transit stations on the property that re protected and untouched/undamaged?
6. Is jointed rail or continuous welded rail used??
a. were jointed track panels used for the installation??
7. What is the weight per foot of the railroad rail?? 65, 85 115,135, 165 pounds per foot??
8. Are wooden railroad ties used or are concrete railroad ties in use?
9. How deep is the ballast bed if stone ballast is used???
10. what if any drainage under the ballast bed is used if any??
11. Is the car mover installed on a continuous slab of concrete which was poured
with the same slab that the track is set upon???
12. Was crushed stone placed below the grade fro drainage and to aid in supporting the slab?
13. Was a moisture barrier installed between the crushed stone and the slab?
14. Was adequate drainage installed under the crushed stone base? Was a sump pump installed? ■

Re: Wagon Indexer (Side Arm Charger)
Hello,
There cannot be actual solution for such issue by simple judgment / inference.
The method is to analyse the stability of concerned machine under acting forces (inclusive of their location with respect to XYZ coordinates). As the requirement is no lift for wheels; resultant force at each wheel should always be positive (downward) during starting, steady running as well as stopping.
There is no special (exclusive) technique or engineering for such calculation. It is similar to foundation load calculation, but with additional presence of inertial forces during non-steady state situations.
The observed wheel lift implies that the machine weight (load) is inadequate at that location. The easiest remedy is to place minimum quantity of counterweight to achieve the result, but then one has to see that the machine design is capable to bear it. It seems the problem is during starting. Then other remedy could be to reduce the acceleration and thereby inertial resistance, but then it will have implication on operating cycle time for the side arm charger as well as wagon tippler and on their time based sensors (if they are present).
The designer of the machine is the right party to decide remedial measures considering all the consequences (because he has necessary data of the machine). If you are user, then you will not have machine intrinsic data / parameters / values; and thereby difficulty in making analyses for practical application.
As pointed by other respondents, also check the straightness / level etc. of the rails on which the side arm charger is running.

Wagon Indexer (Side Arm Charger)
During the hauling of Loaded Wagons with the help of the Wagon Indexer (Side Arm Charger), We have noticed that one of the wheel (Front Wheel) on indexer lifted by 25 to 30 mm. I would like to know the reason behind that & probable solution, if any to restrict the same.
