Types of overhead bridge cranes and main components for sale Egypt
A Bridge crane, also referred to as an overhead crane, overhead travelling crane, or industrial crane, is a type of material handling equipment that is used to lift, lower, and transport loads horizontally. This heavyduty equipment typically utilizes a hookandline mechanism that moves along a horizontal beam which travels on a runway beam, which serves as the supporting structure.
Bridge cranes are capable of handling high lifting capacities and their travel is directed by an operator, either manually or with a wired pendant station or wireless controls. They are commonly used for multidirectional movement of materials to aid in manufacturing, storing, loading or unloading works inside a facility or outside in a yard, railway, shipping port, and other application environments.
Main components of overhead bridge crane kits
The Bridge crane consists of three main components, namely the crane bridge, the hoist or trolley, and the runway. The crane bridge traverses across the runway while the hoist or trolley is the lifting mechanism that moves across the crane bridge and lifts loads vertically. The runway is tied to the building structure. Other parts are also involved in the system, as shown in the following diagram for your reference.
- Crane capacity: maximum weight the Bridge crane is required to handle.
- Crane span: horizontal distance between the rails of runway on which the crane travels.
- Lift or hook height: distance from the floor to the crane hook, which determines the height of the runway from the floor and is subject to the clear inside height of the building.
- Bridge, trolley and lift speeds: rate at which the bridge or trolley runs or at which the hoist lifts; dual speeds are available.
- Crane bridge: main travelling structure of Bridge crane consisting of two end trucks and one or two bridged girders varying with the type of crane.
- End trucks: located on both sides of the span, they house the wheels on which the crane runs.
- Bridge girder(s): principal horizontal beam of the crane bridge supported by the end trucks and meant to support the trolley.
- Trolley hoist: consists of hoist and trolley frame; one or more hoists can be installed according to lifting requirements, which can be supplied on the same trolley or on separate trolleys.
- Trolley: takes the hoist across the bay along bridge girder(s) traversing the span.
- Hoist: mounted to the trolley and is the main lifting equipment together with the crane hook or other lifting attachment.
Overhead crane configuration:
Overhead cranes mainly have two configurations: Top running overhead cranes and under running overhead cranes.
Top running single girder overhead crane under construction
Top running overhead cranes:
The top running overhead crane refers to the crane which has the bridge travel on the top of rails mounted on a runway beam supported by either the building columns or columns specifically engineered for the crane. The top running overhead crane is the most common crane configuration with the feature that the crane loads are transmitted to the supporting columns or freestanding structure and with the advantage of minimum headroom and maximum height of lift.
Classification of top running overhead cranes:
Top running overhead cranes can be further classified into single girder, double girder, and box girder overhead crane in terms of girder types.
Single girder overhead crane is consisted of two end trucks, trolley hoist unit, and a single bridge girder, on the bottom flange of which the trolley runs on. A single girder overhead crane designed for your application can be costeffective. It has lower wheel loads so that it will save on new support structures and it will also allow you to add more lifting capabilities to your runway structure without upgrading.
Double girder overhead crane is consisted of two end trucks, trolley hoist unit, and two bridge girders, on the top of which located the rails on which the trolley runs. A double girder overhead crane provides better hook height for the hoist of the double girder overhead crane is mounted on top of the bridge rather than underneath.
Box girder overhead crane is a crane equipped on a girder formed by multiple walls in the shape of an enclosed tube, rather than on an Ibeam or Hbeam. It is used for heavyduty material handling with the feature of extremely rigidity and durability.
Under running overhead cranes:
Underrunning or underhung overhead crane has the end trucks ride on the bottom flange of the runway, which is usually suspended from the roof, with no need for extra floor columns for the support of the runway. The underrunning or underhung overhead crane has the advantage of taking no floor space and saving cost for supporting systems. Moreover, it can be applied to sloped ceilings or multiple crane systems.
Underhung overhead crane for sale Egypt with capacity up to 10 ton
Classification of underrunning or underhang overhead crane
In terms of crane girder, the underrunning or underhang or under slung overhead cranes can be grouped into single girder, double girder and box girder overhead cranes.
Single girder under running Overhead crane
Single girder under running overhead crane provides you a costeffective material handling solution as it can save new support structure because of its reduced wheel loads. This also makes it possible to add more lifting capabilities without upgradation.
Double girder under running Overhead crane
Double girder under running overhead crane is usually used for handling loads over 25 tons and is usually provided with a complete material handling solution. Double girder cranes provide a higher lifting height for the crane hook travels between the beams, comparing with that of the single girder overhead crane.
Overhead crane comparison top running Vs. under running
To choose the top running overhead crane or under running overhead crane is mainly determined by two factors:
- Capacity: Even though the under running overhead crane can be up to 25 ton capacity, the practical limit is more like 15 tons.
- Support structure: Under running overhead crane can be suspended directly from the overhead steel for the lighter duty crane. Top running overhead cranes need a bracket off the building support steel (up to 10 tons capacity) or independent columns for larger capacities.
Top running overhead crane configuration is best used when headroom is an issue. Double girder top running configuration is the most spaceefficient one. Whereas when the headroom is not an issue a top or under running configuration can be either single girder or double girder.
