can anyone suggest any arrangement to increase the grip without the use of these angles.

(we have to use wheelloaders. there is no other options)

any help will be kindly appreciated

The simplest and least costly solution is adding ballast weight to the 4 tires using calcium chloride in a water solution. Your tire supplier can do this for you if they are familiar with the process of loading tires with water ballast. You equipmwnt dealer could do it as well if they mount and demount tires.

Adding ballast weight with calcium chloride/water mix equal to half the height of the 4 tires will give you plent of traction with no slippage and helps to maintain a lower center of gravity and traction

If your operators are climbing in and out of the pit in anything other than first gear it is a big mistake anyway.

If your tire supplier does not add ballast to tires you could do it using equipment you could buy outright.

One suppier is www.Gemplers.com from the united states. and they accept credit cards for purchases.

Your tire supplier should be very knowledgeable regarding this as road graders quite often are ballasted with calcium chloride/water ballast as well.

another option is Rim Guard Ballast which is a sugar beet derived liquid which is non corrosive.

undiluted windsheild washer fluid which also works and is easy to use and not corrosive.

using a very small four drum slusher hoist with a bucket to pull the material out of the pit and dump it and the second double drum is used to position the traveling cable the bucket rides on.

a smaller double drum winch will be required to position the cable used to swing the bucket from side to side using several; sheave blocks securely anchored to the concrete somewhere ■

There are track mounted front end loaders for swamp duties which might be suitable at the end of your maze.

PS Have you ever experienced difficulty getting very wet pet coke to stabilise on inclined conveyors? ■
