A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The load is attached to the hoist by means of a lifting hook.
The basic hoist has two important characteristics to define it: Lifting medium and power type. The lifting medium is either wire rope, wrapped around a drum, or load-chain, raised by a pulley with a special profile to engage the chain. The power can be provided by different means. Common means are hydraulics, electrical and air driven motors. Both the wire rope hoist and chain hoist have been in common use since the 1800s, however mass production of an electric hoist did not start until the early 1900s and was first adapted by Germany. A hoist can be built as one integral-package unit, designed for cost-effective purchasing and moderate use, or it can be built as a built-up custom unit, designed for durability and performance. The built-up hoist will be much more expensive, but will also be easier to repair and more durable. Package units were once regarded as being designed for light to moderate usage, but since the 60s this has changed. Built-up units are designed for heavy to severe service, but over the years that market has decreased in size since the advent of the more durable packaged hoist. A machine shop or fabricating shop will use an integral-package hoist, while a Steel Mill or NASA would use a built-up unit to meet durability, performance, and repairability requirements. NASA has also seen a change in the use of package hoists. The NASA Astronaut training pool, for example, utilizes cranes with packaged hoists.

Best Versatile Come Along Ratchet PULLER, uses rope. The Made in USA Maasdam A-O Long Haul Rope Puller 3/4-Ton can use any length 3 strand polyester half inch (1/2 inch) rope length and this rope Come-A-long (ratchet puller) will pull for the entire length of the rope. This come be a huge advantage because many come-Alongs's (ratchet pullers) will only pull about 6 feet to 10 feet or a little more. With the Maasdam A-O Long Haul Rope Puller 3/4-Ton you can pull for 100's of feet for as long a rope that you have. The other advantage of this Maasdam A-O Long Haul Rope Puller 3/4-Ton (1500 pounds) is that if the rope broke it would be very easy to replace. Also if a rope breaks on a come-Along (ratchet puller) a rope is not nearly as dangerous as a chain or cable snapping or breaking. The...
Come along, co-co-come, come along
But I don't trust niggas so make sure you come alone
I hand picked you you think sensibly
They friends with you don't need them to be friends with me
Come along I'm gonna take you to some spots that you might like
But bring shades you gonna need them for the bright lights
Grab a drink and invite dykes that like Vic's
We always end up fighting cause that's my vice
Come along, co-co-come, come along
And you'll see how it feels when you're sitting on the throne
When you're so much better but they act like it ain't known
So if somebody else is on it's a temporarily loan
Hard to compete when there ain't no competition
If everybody's the best why I feel like the comp missing
Forced to find inspiration when I never had to
So I go against myself it's a better battle
Come along, co-co-come, Come Along
Turn up the volume on a favorite song
We got so much in common
Except when it comes to rhyming
She feel like lyrics are so intrusive
I feel about her the way she feels about music
Shes cute
She don't like the words, she just like the beat
And I'm thinking me too BIOTCH
(Let It Breathe)
Come along, co-co-come, Come Along
Can't we dim the lights let me get in my zone
Come along, co-co-come, Come along
But I don't trust a soul so make sure you come alone
(Let It Breathe)
Come along, co-co-come, Come Along
And watch these niggas that's doing it all wrong
Throwback swag, nigga still doing rims
Still doing throwbacks, you still doin Timbs?
Looking for a way to save, you ain't earning no cake
Move back in with moms she won't turn you away
Then you all on the blogs showing off on CL
When it's followed by a K gotta know it's a mistake
Benefit of the doubt homie, if that ain't your daughters car
I suggest you stop rapping about a automar
Cause in return I'm just going to call a fraud
Every time I hear a bar about the balla you are
Come along, co-co-come, Come Along
She gonna prolly drop her draws if she step into my home
She probably going to be on cock
It's Big enough to get lost in without Jack or John Locke
On the water like an island thinking' she on the dock
So she puttin in work so I'm thinking she on the clock
Slow down baby what you trying to prove?
When you live like me it's funny what one night can do
(Let It Breathe)
Come along, co-co-come, Come Along
Can't we dim the lights let me get in my zone
Come along, co-co-come, Come along
But I don't trust a soul so make sure you come alone
(Let It Breathe)
Come along, co-co-come, Come Along
Is you niggas out your mind?
Is it hard to recognize when you out your prime?
Maybe they can't imagine living life without that shine
Walk around Hollywood like you're so in demand
But when label stop acting nigga so do the fans
Nigga you ain't a superstar, no allure bout you
And when you talk about me, it says more about you
Come along, co-co-come, Come Along
Wonder why I ain't around niggas changing tone that's the way it looks
But they really think whatever they say behind my back will manage to stay put
We know the same people, go the same places
From the same hood, can only be so evasive
Come along, co-co-come, Come Along
When you're from where I'm from you're going to prolly meet the chrome
It ain't just me, it's like that where we all from
Thought some of them niggas just do it out of boredom
Some just preppin for the day they see a war come
Hanging in the wrong place if you never saw one
Come Along, co-co-come, Come Along
I don't know who you done dealt with in the past
Better be self sufficient ma you don't get a pass
Cause your thighs are thick and you got a little ass
You lookin for a suga daddy then go for it
Twenty something years old with nothing to show for it
Talkin' bout she was raised different
Well get your own pockets bitch so was I
Come along, co-co-come, Come along
I don't call them verses, they similar to poems
Similar to scriptures
Similar to pictures
You can stick to rap what we doing is much bigger
(Let It Breathe)
Come along, co-co-come, Come Along
Can't we dim the lights let me get in my zone
Come along, co-co-come, Come along
But I don't trust a soul so make sure you come alone
