What is Difference Between Crane and Hoist?

Hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects. The scope is specified as an elevator with a rated lifting capacity greater than or equal to 0.5t; the rated lifting capacity is greater than or equal to 3t (or rated lifting torque). A tower crane with a height greater than or equal to 40 t·m, or a loading and unloading bridge with a productivity greater than or equal to 300 t/h, and a crane with a lifting height greater than or equal to 2 m; a mechanical parking device with a number of layers greater than or equal to 2 layers.

The hoisting machinery lifts or lifts and lifts the weight by means of a lifting hook or other pick-up device. The working process of the lifting machine generally includes steps of lifting, running, lowering and returning to the original position. The hoisting mechanism lifts the heavy object from the picking point by the taking device, shifts the weight through the running, turning or luffing mechanism, and returns the weight to the original position after placing the heavy object at the designated place.

The basic mechanisms of the hoisting machinery are different in the use of various hoisting machinery, and there are great differences in construction, but they all have a hoisting mechanism that realizes the basic action of lifting. Some hoisting machinery also have an operating mechanism, a luffing mechanism, a slewing mechanism or other specialized working mechanism. The material can be lifted and lowered by a flexible member such as a wire rope or a lifting chain, or it can be lifted by a screw or other rigid member. The hoisting machinery is a space transportation device whose main function is to complete the displacement of heavy objects. It can reduce labor intensity and increase labor productivity. Hoisting machinery is an indispensable part of modern production. Some lifting machinery can also perform some special process operations in the production process to make the production process mechanized and automated.

crane


A crane is a kind of hoisting machinery. It is a kind of machine for circulation and intermittent movement. A work cycle includes: the picking device lifts the item from the picking place, then moves horizontally to the designated location to lower the item, and then performs a reverse motion to return the picking device to its original position for the next cycle. Such as fixed slewing cranes, tower cranes, truck cranes, tires, crawler cranes, etc. It is widely used in lifting and handling machinery in ports, workshops, electric power, construction sites and other places. The name of the crane is the uniform title of the crane. The cranes are usually called car cranes, crawler cranes and tire cranes. The purpose of the crane is to hoist the equipment, rescue, lifting, machinery, and rescue.

The Difference Between Hoist and Crane

The functions of the crane and the hoist are the same. The crane is included in the hoisting machinery, but the crane has a larger scope. That is to say, the lifting machine also includes a crane, but some lifting equipment cannot be called a crane. Elevators, lifts, etc. are attributed to lifting equipment, but cannot be called cranes. Cranes are special machines for hoisting machinery, lifting with pulley hooks (also for lifting chains), bridges and gantry cranes for industrial production, mobile cranes, floating cranes, Crawler cranes; cranes with the same base; and some special cranes.

As the main tool for lifting materials, the appearance of cranes plays a very good role in the lifting and handling of heavy objects in people's work. For cranes to carry heavy loads, there must be a hook fit, and there are many types of hooks, but they are each suitable for different cranes.
