The difference between a crane and a hoist

Lifting medium is a flexible material that connects the hook to the top of the lift. It can be rope, metal cable, welded chain or roller load chain. Welded anchor chain is like an anchor chain, a set of identical metal rings joined together to form a line. Like a bicycle chain, a roller chain is made of alternating roller links and pin links that form a line that easily engages a toothed gear.

Lifts can be manually, electrically or pneumatically driven. Manual hoists use pulleys to increase the pulling power of the operator. You can also use electricity or air to drive the motor in the lift. Plants equipped with many pneumatic tools may find pneumatics more convenient.

The method of suspending the lift depends on how it is used. When you just need to move the load vertically (from a truck to a trailer, for example), a hook-mounted lift is a simple solution. Meanwhile, the lifter bolted to the crossbar can handle heavier loads. The lift can be mounted on a trolley that runs along a beam or rail, thus enabling you to lift the entire machine.

A bridge crane is a lifting device that is installed in workshops, warehouses and areas to lift materials. It is shaped like a bridge because its ends rest on tall concrete pillars or metal supports. Bridge crane bridge along the track laid on both sides running high longitudinally, can make full use of the space under the bridge lifting materials, is not hindered by ground equipment. This is the most widely used and the most number of lifting devices

Hoists and cranes are both machines that help move and lift heavy loads at work, but they have many fundamental differences in their design and use. A lift can move heavy objects up and down. Elevators are probably the most well-known lifts. Elevators are ideal for moving loads vertically, but cannot move loads in other directions (a different function than a crane). On the other hand, cranes can perform two-dimensional or three-dimensional movements. Overhead cranes are suspended from beams or move along rails. As cement is an integral part of concrete, the lifter is the central part of the overhead crane. Basically, the crane is moving the lift. A crane is a multipurpose lifting device that lifts vertically and moves heavy objects horizontally within a certain range. The crane is on a special lifting mechanism, the lifting mechanism of the beam in the left and right movement is commonly known as trolley, the beam moves on the rail mechanism called the big machine, the electric hoist is only on the I beam or overhead crane and is down Execution cannot achieve forward and backward movement. The difference between a crane and an electric hoist is that "the former is a machine, while the latter is a mechanism", the electric hoist is the "lifting mechanism" in the crane. An electric hoist is a type of crane lifting mechanism, which can also be called a small crane.

1. Crane: multi-stage lifting machines used for vertical lifting and horizontal movement of heavy loads in the large construction industry.

2. Electric lifts: lifting equipment used in industrial and mining companies, warehouses, docks and other places.

3. Elevator: Elevator is usually used for rescue and renovation..

1. Crane: the driving cabin and the lifting control room into one is the evolution of the crawler crane (crawling crane), the crawler walking mechanism and the walking support part into a chassis with rubber, to overcome the crawler crane (crawling crane). ) crawling screen on the road to damage material handling machinery cons.

2. Electric hoist: large size in length, large size in width, crude and stupid structure, low mechanical efficiency, more difficult processing, etc.

3. Hoist: Using high strength and high quality aluminum alloy material, it has the advantages of beautiful shape, small volume, light weight, smooth lifting and lowering, safe and reliable. It is light in appearance and can perform the highest lifting capacity in a very small space. The column lifting system has the characteristics of high load capacity, strength, large platform area and easy implementation.
