How Drilling rig Hoisting System Works I Drilling Rig. :

 which is hosting systems now

by hosting the term hosting means that

we need

the lowering and raising of the tubular s

in in the vapor and out of the well-bore

now in order to drill the hole in order

to change some components

of surface components we need to raise

and lower the

tubular s time to time hosting system

mainly consists of three components

the first one is a direct second one is

a draw work and the third one is a block

and decal system

so here in this picture this one this

structure is known as a derrick

now derrick is not work over an

oil well uh it is a structure of an oil

well that allows the drilling machinery

to be raised and lowered

now coming on to the draw work actually

draw work

what what it does is that it provides

the hoisting and breaking power to lower

and lift the heavy load of drill string

and casing

into the Velcro and out of the well

board

you must have flown kites in uh in a

childhood and

so you must he's to uh

to control the kite to control the speed

of quiet to height of the kite

so you can think of a draw work similar

to that jerky

see here this

this uh this actually this structure

rolls and allows the

uh drilling line to get over the

tubular s in order to

lower the tubular s into the valve board

and it also has a braking system uh

which means that when

when we need to stop we can apply apply

these brakes in order to stop the

stop the uh lowering of the tubular in

the valve

now coming on to the block and tackle

system

what broken tackle system is so

basically

a system of two or more pulleys with a

rope between them

or multiple ropes between them is known

as a block and tackle system

it is uh it is used for uh

for lifting the heavy loads

now in here here in hosting systems

block and our broken tackle system

consists of a

ground block traveling block a hook a

fast line at that level

now what each of them functions is

ground block and traveling block is

nothing but of a

frame which consists of multiple pulleys

between them in 

a crown block is at the top of the

derrick

and a traveling block is below the crown

block

and in between crown block and a travel

block there are multiple lines

multiple drain lines i am talking about

these drilling lines

two three four these drilling lines

and this this all this whole structure

is known as a crown block

and this structure is known as a

traveling block

now actually drilling line comes from

the draw works

the drilling line which is coming from

the draw box to the first pulley of

crown block.

but our fast line is always constantly

moving so that way it is known as fast

and uh the deadline is known as a

deadline

now in below the traveling block there

is a

uh there is an element called hook this

is a hook

this hook carries all the weight of the

leg means all the tubular all

everything

which is going into the well board is

connected through this hook

so uh now one more element is there

which is known as a deadline anchor

deadline anchor is nothing but

a provide a static static uh

static what we say support

to the uh to the deadline it also has a

it has it also measures the hook load it

also has a

machinery which used to measure the hook

load.
