What is an end truck in a bridge crane?

What is an end truck in a bridge crane?

About End Trucks End trucks carry the hoist and crane up and down the crane runway. R&M end trucks and bridge drives are available in a variety of top and underrunning configurations that are custom-designed to fit your crane’s application.

What are the three basic types of overhead cranes?

TYPES OF OVERHEAD CRANES

  • Top Running Overhead Crane. ​ The bridge of a top running overhead crane is designed to travel on rails that are mounted onto the runway beams.
  • Under Running Overhead Crane. ​
  • Single Girder Bridge Crane. ​
  • Double Girder Bridge Crane. ​

What is an overhead crane called?

bridge crane
An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap.

What is a Underhung crane?

Underhung cranes—sometimes referred to as under-running cranes—do not require supportive floor columns. This is because they typically ride on the lower flange of a runway beam suspended from the facility roof or rafters. By optimizing end approaches, underhung overhead cranes make the most of facility space.

How are bridge girders connected to end trucks?

A flexible end tie is used between the girders to permit equalization of the wheel loads by torsional deflection of the girders and flexing of the end tie. BOOM (OF GANTRY CRANES): An extension of the trolley runway that may be raised or retracted to obtain clearance for gantry travel.

Is an overhead crane that has an overhead beam supported by truck or rail system carrying a bridge trolley and hoist?

A gantry crane is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. These legs travel on rails that are embedded in, or on top of the floor or ground structure.

Which type of crane is built upon a bridge like overhead structure?

Bridge Cranes
Bridge Cranes This type of overhead crane is built inside of a building and will normally use the structure of the building as it’s support. An overhead bridge crane almost always has a hoist which will move left or right.

What is the difference between a bridge crane and gantry crane?

Bridge cranes are mounted inside of the building they operate in. This makes them great for warehouse type factories that are often crowded and where every inch of space is valuable. Gantry cranes are typically on wheels or mounted to a track system .

What are the components of an Underhung crane?

A crane runway is the steel structure on which bridge cranes operate. A top running crane runway consists of (3) components, the columns, the runway beams and the crane rail. An underhung system consists of runway beams that are supported from above by the building.

What is a monorail crane?

A monorail crane system is a stationary, overhead track on which trolleys travel to carry loads from one place to another in a facility. Monorail cranes are an ideal solution for linear, overhead material handling due to the fact that they enhance production workflow and create a safe and secure work environment.

What is LT and CT in crane?

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. CT End carriage : Structure which houses Cross Travel Wheels.

What is the overhead crane runway?

RUNWAY: An assembly of rails, beams, girders, brackets, and framework on which the crane travels.

Is a jib crane and overhead crane?

Overhead cranes are normally operated by electric power systems. Jib cranes are typically used in industrial sites and on military vessels. A jib crane features a horizontal jib that supports a movable hoist and is attached to a wall or a pillar that is fixed to the floor.

What is overhead crane used for?

Overhead Cranes are used in a variety of areas to support processing and handling throughout a facility: Assembly: Moving products through production processes. Transportation: Loading finished products onto open trailers or railcars. Staging: Holding work-in-process for additional production processes.

Is overhead crane and gantry crane the same?

Overhead Cranes are widely used in indoor areas or inside the buildings. While gantry cranes are more widely used in outdoor areas or outside the buildings. Overhead cranes can be installed by utilizing the building’s column construction so that they are able to serve most of the areas in the building.

How many types of overhead cranes are there?

The different types of overhead cranes include gantry cranes, jib cranes, bridge cranes, workstation cranes, monorail cranes, top-running, and under-running.

How does a overhead crane work?

Overhead cranes cover a rectangular area, moving a load side to side and backward and forward. The lifting device, called a hoist is mounted on a trolley for horizontal movement across a bridge beam connected to one or more horizontal girders which are supported at either end by end trucks.

What is mobile and overhead cranes?

Mobile Gantry Cranes provide economical material handling in areas where an overhead crane system is not available or practical. Their safety and efficiency make them a frequent choice for production, installation and maintenance applications. They are often used in maintenance shops, machine shops and loading areas.

What is the difference between monorail crane and overhead crane?

The Difference Monorail and Crane. Monorail can only move in two directions, in the vertical direction (up / down) or on the Y axis and in the horizontal direction along monorail beam or on the X axis. While crane able to move in three directions or more on the X, Y, Z axis and move radius in the vertical axis.

What is DSL in EOT crane?

Product Description. Shrouded Bus Bar (DSL) system are used for the electrification of mobile equipment. Shrouded bus bar is a safe, economical and low maintenance way to solve mobile electrification requirement. Systems can be designed to accommodate 60 to 1200 amperes.

What is an underhung overhead crane?

By optimizing end approaches, underhung overhead cranes make the most of facility space. That is, they allow the hoist to get closer to the end truck or end of the runway than is possible with a top-running crane.

What are the features of bridge crane end trucks?

The bridge Bridge crane end trucks has the features of ultimate light-weight, compact size, and meticulous dedicated design. More picture on overhead End trucks, please check End trucks on Single Girder Crane and Double Girder Crane.

Why are cranes underhung on runways?

The underhung configuration also maximizes the bridge end approach, or how close the bridge girder can get to the wall or the end of the runway. Considerations: As their beams are suspended from building roofs, underhung overhead cranes are limited in lifting capacity—usually 10 tons or less.

What is the span of a crane end truck?

Under-Running Angle Type End Trucks: Capacities: 1/2 through 2 ton, Span: Up to 30 feet. Crane end trucks are constructed out of heavy steel angles with pressed steel or forged wheels.
