What are the main parts of a crane?

Cranes consist of four key components:

• Hook. The hook element of a crane is the part that holds or carries the load and connects it to the hoisting element.
• Hoist. The hoist element of a crane provides the vertical lifting and lowering power.
• Trolley.
• Bridge.

What is LT and CT in crane?

How many types of EOT cranes are there?

There are mainly two types of EOT cranes- single girder EOT and double girder EOT.

What is trolley in EOT crane?

The trolley is the mechanism that moves the hoist along the bridge girder of a crane. There are three types of trolleys: low headroom, normal headroom and double girder trolley.

What is crane hoist?

Crane hoists are machines that are able to lift and carry heavy objects and move them to another location. They use either wire, rope, or chains to lift and their power source is either an electric engine or an air motor.

What are the parts of a mobile crane?

Which motor is used in EOT crane?

slip ring induction motor
The slip ring induction motor is connected to power resistance in 4 to 5 steps by power contactors.

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.

How are overhead EOT cranes operated?

These cranes are electrically operated by a control pendant, remote control or from an operator cabin attached to the crane. Overhead eot crane has different configurations include single girder and double girder. The crane consists of one girder beam, with trolley and hoist running on the bottom flange of the single girder.

What is an electriceot Crane?

EOT crane, also known as electric overhead travelling crane, is the most common type of overhead crane used in many factories, warehouses, material yards, etc. These cranes are electrically operated by a control pendant, remote control or from an operator cabin attached to the crane.

What is a single girder crane?

The crane consists of one girder beam, with trolley and hoist running on the bottom flange of the single girder. The single girder crane has simple structure, low operating cost, quick installation and easy maintenance. There are two girder beams, and trolley and hoist run on a rail installed above or below the bridge girders.

How is the main beam supported on the crane track?

The main beam is supported on the crane track through the end beams at both ends. The end beams are composed of slab beams and wheel sets. Some bridges are equipped with walking platforms and safety rails. The bridge moving mechanism and trolley power supply device are generally installed on the walking platform.
