Hoist vs Crane
If you are not from a construction company, you are probably not aware of the differences between a hoist and a crane as both perform similar functions of lifting loads up and down. In any case, these are devices or contraptions used in construction activities or mining activities where loads are taken from one place to another. The concept of a crane is not new, and even a hoist is a very old system. Hoist has been in use since ancient times when high buildings necessitated the use of pulley and rope to send construction material up while also providing a way for transport of men up and down. However, there are many differences between hoist and crane that will be discussed in this article.
什么是葫芦?
A hoist is a piece of machinery that is used to lift and lower loads vertically. It cannot move in any other direction like moving horizontally. Just like anelevatorthat can move only up from down and down from up along the same line, a hoist can only move up and down along the same line vertically. A hoist can only be used for this purpose of lifting and lowering loads. That means, a hoist is not a multi-purpose machinery. A hoist may be an independent machine, or it may be used as a subsystem in a crane. This implies that cranes are much more complex devices than hoists that have one known function, and that is to raise and lower a load.
What is a Crane?
Have you heard the phrase crane out your neck? You must have seen a crane standing for long hours in water and stretching out its neck to pick up fish from under the water. A crane in industrial and construction setting does just that as it sticks out a beam ahead of its arm that picks up a load from down and can move it in all directions whether it is left, right or in the vertical direction. A crane proves very helpful in a construction site or even a quarry wheremineral or rocks在起重机的帮助下被开采并拖到地球表面。这就是为什么据说起重机具有三个自由度的原因。如果您玩过著名的游戏,您可以操作起重机的手臂将钩子放在玩具下以捡起并将其带到某个点以赢得玩具,那么您就会知道起重机的运作方式。起重机的臂是液压的,坐在机舱内的操作员使用此手臂捡起负载并水平移动,或者将此负载垂直移至特定点。起重机在将负载从一个地方移动到另一个地方具有很大的灵活性。如果一个人在游戏中用提升机取代起重机,那么一旦玩具被爪子捕获到水平方向,就可以移动它的所有灵活性。
While a hoist can pick a load and move it vertically only, a crane can be used for demolition purposes too. This is done by hanging a big iron ball through the crane and banging this ball by bringing it from behind and moving it at a great speed to hit the structure to be brought down or razed to the ground.
What is the difference between Hoist and Crane?
• Direction of Movement:
起重机和起重机都用于升高和降低负载。
• Cranes can move loads in horizontal direction too, in addition to moving them vertically.
• Hoists can only move loads in a vertical line. Horizontal movement of loads is not possible with hoists.
• Design:
• Cranes are complex machines that have mutipurposes.
• Hoists are simpler in design than cranes and are often a subsystem in a crane.
• Uses:
• Crane:
•起重机用于移动负载。
•将起重机可以用于拆除a wrecking ball to it.
• A crane can also be used to remove waste material from a site by attaching a scoop to it.
• Hoist:
• A hoist is used to just lower and raise loads vertically. It has no other use.
