7 min readMay 22, 2021

Rope haulage dominating mode of transport in Indian Coal Mines through belt and chain conveyor where introduced on the large scale in my phone within the last two decades.

Types of rope haulage

There are 4 types of rope haulage

1.direct rope haulage

2.endless rope haulage

a.over rope

b.on the rope

3.main and tail rope haulage

4.gravity rope haulage

1.DIRECT ROPE HAULAGE

ADVANTAGES

Direct rope haulage this is the simplest employing one pulling rope and one haulage drum for hauling mineral are cause of the gradient which is generally steeper that 1 in 10.
The whole engine is situated at the top of an incline roadway.
The train and tubes are attached at one end of the Rope they being fixed to the holiday drum.
The empty drum or was attached to the end of the haulage Rope travel on the down gradient by their own weight and do not require power from the power engine.
The Rope speed is generally 8 to 12 kilometre per hour.
only one holiday track is required
The branch road debited at an angle of not more than 40 degree of the main road.
Disadvantage
high peak power demand as load start its journey of the gradient
breaking duty on the downward run
high hold speed demanding high standard of track maintenance.
not suitable for mold inclination of road.
A damage is associated with heavy damage because of the high speed

Direct Rope double drum balance haulage

This is modification of the direct haulage system in the double drum method to drums are provided so that when it rain of full tubes is being hauled out by a set of empty tube is lowered in by both the drums are fit with thick largest and their mounted on the same SAP weight of the Rope and tube are balanced and the only on balanced load for the holiday engine is generally of the mineral result in a reduced peak power demand and is your breaking the system gives highest output at each trip of the ropes bring the load and there is a regular delivery of the loaded tube the system required by the road for the smallest track.

2.ENDLESS ROPE HAULAGE

Hindi system there are two parallel tracks side one of the tube and other for the empty and an endless Roop passed from the driving draw Puli located at the output end of the college road to the environment and and attention Buggy loaded as well as MP attached to the Rope at regular interval with the help of clips so that the entire Rope lens has tube on it intervals
Only one tube is attached to the Rope at a time but where last seen chain is used for attachment the normal practice is to after is set of tools and the attachment of detachment is performed by stopping the Rope if a Bolt leaves are used for signal stutes there can be attached or detached when the rope in motion the gradient of a college road is mailed or exceed one in six.
speed range between 3 kilometre per hour and 70 km per hour and the whole slow moving the Rope moves in One Direction only squirrel cage motor is used.

CLIFTON PULLEY

The driving Pulley of an endless holiday is krypton Kohli or search while and is of special shape to protect the main driving while from the pulley is fitted with renewable meaning of cost of 3 segment have been of about one in eight.
These segments are fixed on the rim of the driving who will buy counter song bolts and half side triangle the incoming rope pulling load enter the segments leave them at the smaller diameter the Rope should not be lost on the pulley and the order to keep in the proper tension due to pollution of THE LOAD.

Advantages of endless haulage

Because of the Slow speed less wear and tear
accident from tubes do not cause much damage due to Slow speed
Motor of less power required
It does not Place heavy peak demand on the power supply

Disadvantages of endless haulage

It requires wide roads for two tracks
It is not suitable for steep gradients
load on the Rope is large and a rope of a larger cross section is required
large number of tubes and sleeves are required as rolling stock
down of any tube across the whole system comes to a standstill
A Main Road and a branch Road simultaneously on list elaborate arrangement are made of course the Rope to the branch line with the help of a deflection police the tubes Main Road rope have to be discharged or reactors at the branch line.

reversible balanced haulage with endless rope

This may be required at the end of the double drum balance solid system whereby the full and empty trains instead of being attached to two separate routes are secured by clips to an endless rope which is driven by a reversible sugar wheel.

It processes the advantages of the double drum system and in addition more accurate meaning of the loaded and empty train and more in form of the Rope can be obtained merrily by adjusting the position of the clip on the ropes.

3.Main and tail rope haulage

Hindi system hauling engine is provided with two separated from one for the main rope which holds the full train out and one for the tell Rope which hold the empty train in one drum in in your the author was freely on the staff but control when necessary but the break to keep the ropes don’t Tum main rupees approximately equal to the length of the plane and the tell Rope twice this length wants one track is required.

the system of knowledge is suitable for on letting Roadways where it is impossible on desirable to maintain the double track required for endless rope haulage can readily calls and it is convenient for working branches.
on the other hand it operates at a fairly high speed and with long train and derailment across the resulting damage and delay are likely to be considerable.

Tail Rope haulage

Airtel rope haulage is one in which the whole is situated at all available and the empty are hosted of the sloping track the haulage Roop passed to the train of empty tubes bhaiya a deflection Puli located at the top of the roadway downward travel by gravity on the gradient bought at the Rope is attached to them they are sent is controlled by the haulage driver.

4.GRAVITY HAULAGE

This haulage without any motor or external source of power and consists of cast iron Pulley 1.3 to 2m to diameter Having brake pad on one side and a strap break.
It is located at the top of an incline roadway and is employed to low your by gravity load attached to one end of the Rope while simultaneously costing MTS attached to an end of the Rope which passes around the DIG police police tickle only signal is required for its operation bought at the end of the road where the loads are double track or a bypass is essential.

Essential of a good haulage track

Rails of articulate weight and cross-section to carry the load
plated joints with lock and bolts the joint being squares across the track except on where they should be struck red.
length and cross section preferable with steel channel pause at a interval to give rapidly and maintain the Gauge.
drainage to maintain the track in a dry condition
full alignment before and after blasting
careful grading
