What is the working principle of EOT crane?

What is the working principle of EOT crane?

EOT Crane Working Principle system consists of three working movements: crane hook up and down lifting, trolley lateral movement and crane long traveling longitudinal motion. 1. Transmission of hoisting system: the driving force of hoisting mechanism is from motor.

What is hot cranes?

HOT Cranes HOTs are a stationary overhead crane and allow for lateral movement across two planes as well. They are less common as compared to EOT crane as they do not allow for as much movement as the EOT cranes. They are more commonly used for maintenance purposes.

How does an overhead crane work?

Overhead cranes cover a rectangular area, moving a load side to side and backward and forward. They typically incorporate a top running trolley hoist which moves along the top of the two bridge beams on its own set of wheels for increased headroom under the crane; also called a top running crane.

Which is the basic components of EOT crane?

Parts of EOT Cranes

• Hoist. – The hoist is what creates the lift in lifting systems by holding, raising, or lowering the load using wire rope or chains.
• Trolley. – Trolley’s support the hoist and moves along the crane’s bridge.
• Bridge.
• Columns.
• Runway.
• End Effectors.
• Reinforced-steel cable.
• Hook.

What is CT and LT in crane?

AH : Auxiliary Hoisting motion. LT motion : Long Travel Motion. CT motion : Cross Travel Motion. Bridge : the structural portion on which the trolley/crab moves. LT End carriage : Structure which houses Long Travel Wheels.

Which gear is used in EOT crane?

Single, Double and Triple stage Horizontal gear units type HA, HB and HC are recommended for Hoist and Long Travel drive. Three stage vertical gear units type VC are recommended for cross travel drives of the EOT crane.

What is mot crane?

the transportation and lifting of heavy load. These cranes may be manually (hand) operated overhead travelling cranes (MOT) or electrically operated overhead. travelling (EOT) cranes.

What is the bridge on a crane?

BRIDGE – That part of an overhead crane consisting of girders, trucks, end ties, walkway and drive mechanism which carries the trolley and travels in a direction parallel to the runway. BRIDGE GIRDER – The main horizontal structural member(s) of the crane bridge supported by the end trucks.

What is Stacker crane?

They are machines designed for the automated storage of materials. They travel along the aisles of the warehouse, where they enter, position and extract materials. The stacker cranes are guided by a management software system, which coordinates all the activities.

What is headroom in crane?

Headroom : distance between the topmost part of the crane to the hook saddle when the hook is at the topmost position. Overhead clearance : distance between Gantry rail top to the building roof lowermost position.

Which motor is used in cranes?

Answer: As the purpose of the crane is to lift heavy load through rope or chains, so it demands a kind of motor, which has a very high starting torque to lift the load at low current. Squirrel cage induction motor has the problem of low starting torque due to low resistance.

What is the use of a hot Crane?

We are proficient in manufacturing Hot Crane that allows a safe and efficient lifting of heavy material loads. Finding an application in factories and construction companies, it allows an easy access in all directions. Offering a high performance, the crane is durable as well.

How does a crane move up and down?

How Does A Crane Work? When asked, how does a crane work, most people would have a straightforward answer in mind. Something like, a crane has a long arm or boom used to lift and move heavy objects that can move up and down and rotate 360°. The one end is anchored to a base while heavy objects attach to the other.

What kind of power does a crane use?

The cranes are generally powered by electric motors, hydraulic power or internal combustion engines, but the rapid technological development will allow us to see another type of food in the future.

What is the working principle of an electromagnetic Crane?

Electromagnetic Crane Working Principle. 2021-02-19. 2018-01-15 by ellsodov. Electromagnetic Crane is a kind of lifting machine that uses electromagnetic principles to carry steel articles. The main part of the electromagnetic crane is the magnet.
