What is a Gantry Crane?
A gantry crane is a type of overhead cranes with freestanding supporting leg or legs that moves on crane rail / crane track , or crane rail system, carrying crane bridge, consisted one beam or double beams with hoisting trolley system for material handling. Gantry cranes have lifting capacities ranging from a few hundred pounds to several hundred tons, which can be up to 550 ton with processed crane design. They are very efficient and cost-effective material handling to lift and move loads of various type, size or weight.

Gantry cranes are typically used in open areas or outdoor use where a closed area is not required, but they can also be used indoors such as workshops warehouse, and maintenance room, etc. The design, engineering, fabrication processing and providing all types of technical service for the gantry Crane are available from us. No matter which industrial sector you are in, we are able to provide you one-source gantry crane services, typically, in shipyards, rolling mills, enterprises serving the iron and steel industry, stock areas, marble shops, industrial facilities in machinery manufacturing, and any business that needs to lift loads. Although gantry cranes are commonly referred to as open area cranes, outdoor cranes or external cranes, they also can be used in enclosed spaces, with no cantilever, etc.

Main Types of Gantry Cranes & Comparison
Gantry cranes come in a variety of types and styles, varying with different loads and lifting capacities. Due to diverse shapes and sizes, gantry cranes can be used in a variety of industrial applications. The distinction between types of gantry cranes is determined by crane girder configuration, crane size, and hoisting trolley, etc.

Gantry cranes are classified into different types based on configurations, designs, and lifting capacity, which are interacted in a variety of ways to define the type of gantry crane for the specific applications.

Full gantry crane
The full gantry crane is the standard configuration of a gantry crane, consisting of a cross beam, supporting legs, and a lifting hoist . Gantry Cranes can run on rubber tyred wheels, or move on embedded rails or tracks, or be portable with castors which will be selected based on their designs.

Semi Gantry Crane
A semi-gantry crane has one supporting leg on one side of main girder and the other side is supported by a wall-mounted I beam. A semi-gantry crane is made up of a bridge, crane mechanism, trolley, and hoist. Semi-gantry cranes are combined the advantages of overhead and gantry cranes which can be used both indoors and outside. Gantry cranes are frequently used under the beneath an overhead crane to improve work productivity without interfering with the overhead crane’s operation.

Portable Gantry Crane
Portable gantry cranes are light in weight and have movable wheels or casters which make the small gantry crane more flexible. The small portable gantry cranes are come in the types of steel gantry crane and aluminum portable gantry crane and the lifting capacity of portable gantry crane are from 500kg to 10 ton, and up to 20 ton and the lifting heights and spans come in diverse of designs. Portable gantry cranes are a cost-effective alternative for infrequent lifting needs that perform as well as a permanent crane. They can be moved about a facility for material handling at your request.

Adjustable Gantry Crane
Adjustable cranes come in a variety of sizes and can be portable or stationary. They can adjust their height, width, and horizontal beam to accommodate a load. The versatility and convenience of an adjustable gantry crane are two of its advantages. Though light duty adjustable gantry cranes are widely used. Many gantry cranes, regardless of type can be designed with the adjustable features to meet the different material handling requirements.

Single Girder Gantry Crane
A single girder gantry crane has one bridge beam with a hoist trolley that suspends on the lower flange of crane beam girder. . The main parts and components of a single girder crane are consisted of the main beam, end carriages, support legs, , crane drive, crane controls, and electric hoists, including the electric chain hoist and wire rope hoist, which are selected according to the type of work and application conditions. Single girder gantry cranes can be configured as semi leg / one leg gantry or two leg gantry cranes which is also dependent to on your working conditions.

Double Girder Gantry Crane
The bridge of a double girder gantry crane is made up of two girder beams. It is designed for extremely heavy duty applications and can have a top or under running trolley. Double girder gantry cranes have a large span, a high bearing capacity, and excellent stability. A double girder gantry crane has a lifting capacity of 3 ton to 550 ton and can be semi- or two-leg designed with A frame legs or U frame legs.

Truss Gantry Crane
A truss gantry crane refers to the type of gantry crane with the its main girder made of steel made truss girder and the trolley runs on top of the truss girder and a driver‘s cabin is equipped with double truss beam designs. Truss gantry cranes are light in weight and exert little wheel pressure. Truss gantry cranes can be designed as any of the various types of gantry cranes, regardless of the girder and frame construction.

L Shaped Gantry Crane
The L shaped gantry crane is a single girder gantry crane with with L shaped supporting legs. The design of the L shaped gantry crane legs makes it capable of large and long heavy objects or loads.The L leg gantry crane is also widely used in freight yards, railroad terminals, and warehouse, with capacity of 5 ton -32 ton. Based on your lifting requirements and application conditions, the L leg gantry cranes can be designed with a soft start for long travel operation to make sure your gantry crane move stably and smoothly.

Workstation Gantry Crane / Portable Gantry Crane
Workstation gantry cranes are small gantry crane with rollers or castors which are supposed to lift lighter materials and goods. They are portable and mobile, with the purpose of lifting a work-piece and transporting it to a workbench for processing. Workstation gantry cranes with manual travelling design remain stable and stationary when loaded. With motorized travelling design, the portable gantry crane can be movable under loading . For lifting and moving workplaces, the hoist is equipped with a wire rope or chain. The selection of workstation gantry crane or portable gantry crane are determined by its required lifting capacity and the types of loads to be handled.

Gantry Crane Parts & Components: How Gantry Cranes are Made
Frame
The main structure of a gantry crane is mainly made of main girder or beam and its supporting legs. In the case of a semi-gantry crane, the structure is cross beam and one supporting leg. The crane girder or crane beam is the main supporting structure of the load. The size, length, and number of crane girders are determined by the working duty of gantry crane, the weight of the lifting loads, and the operation environment. In terms of supporting legs, the gantry crane is usually adopt rigid supporting legt on one side and flexible supporting on the other side to reduce deadweight and account for span deviation.

Trolley
The trolley, which can be attached to the top or bottom of the crane girder, moves the hoist horizontally along the girder. In terms of trolley design, there are three types including the low headroom trolley, general use trolley and double girder trolley.

By adding or removing washers, the distance between trolley wheels can be adjusted to make the trolley to match the girder . Screw adjustment trolleys make adjustments with a screw mechanism. Wheel bumpers keep the trolley from colliding with other objects, and side guide rollers keep it from swaying.

Hoist
The electric hoist or manual hoist on a gantry crane is a form of lifting equipment which are installed on the trolley frame to lift and lower the load vertically, and and trolley carry the electric hoist to move back and forth horizontally . Gantry Hoists can be either Electric Chain Hoist or electric wire rope hoists.

The configuration of the wire rope or chain, as well as the blocks and drum of the hoist, is referred to as reeving system. The many types of reeving have an impact on headroom, lifting speed, and capacity. The gap between the beam and the hook is known as headroom. The number of ropes or chains is referred to as single or double.

Power
The trolley and hoist are powered by a festoon, which is a type of wiring. The crane is powered by power from the busbar, or receiving station, which is supplied to the bridge panel. The hoist, trolley, and bridge are all powered by cables that extend from the panel to the hoist and bridge drives. A gantry crane can be powered by direct AC, induction AC, or synchronous power.

The diagram below shows a festoon system using spherical cables.

Hook
Hooks are designed and manufactured in accordance with the GB/T 10051-1988 standard.
The hook is a single forged hook that was forged by DG20.
To prevent the lifted loads from being unhooked, all hooks include hook closures.
To ensure the wire rope’s service life, the diameter of the pulley must be greater than 20 times the diameter of the wire rope.
Protective covers or devices are used on the pulleys to keep the wire rope from jumping out of the groove.

Drum Group
The drum device is mainly composed of drum gear ring, drum, intermediate shaft device, bearing base and limit guide rod device. Rope grooves are machined on the drum to make the wire ropes orderly arranged.

Wheel Set
The diameter and material of the wheel are chosen based on the wheel’s maximal supporting force under the most adverse situations to ensure that the wheels are not overburdened.
The wheel material is ZG340-640, and it is heat treated and quenched using advanced power frequency heat treatment.
The wheel tread and inner surface of the wheel flange must be free of flaws, and welding repairs are not permitted.

Electric Motor
The motor’s insulation class is F, and its protection class is IP54/IP55.
The motor features a sensible structure, consistent performance, good quality, huge overload capacity, and strong mechanical strength.

Reducer
The reduction is a crane-specific reducer with high carrying capacity, efficiency, and minimal noise and vibration.

Brake
The brake is an electro-hydraulic block brake from the YWZ series, which is stable, safe, and dependable.

Controls
The controls of a gantry crane give the operator direct control of the crane‘s movements and the hoist. There are several varieties of crane control methods, ranging from wired or remote control for a small sized gantry crane to cabins and booths where the operator rides on the crane or sits in a location to observe crane movement.

Generally, for the single girder gantry crane for universal use is usually adopt the pendant or remote radio control with buttons, levers, or other command devices while for double girder gantry crane with higher capacity or for specialized application, the crane driver’s cabin will be recommended.

Industrial Applications of Gantry Crane
Gantry cranes are employed for a variety of industrial and construction purposes, depending on their size, lifting capacity, and ability to move about the work area. That’s why you should select a gantry crane with proper dimensions. Here are a few examples of gantry cranes in operation.

Manufacturing Plants
Gantry cranes are used in a variety of production sectors, ranging from small to medium to large scale. Gantry cranes are most commonly used in the automobile, steel, and airplane manufacturing industries. You can employ single or double girder, portable, and adjustable gantry cranes depending on the purpose. Small single-girder gantry cranes, for example, are used in the automobile industry to put engines into cars or to handle the mold to the processing line.

Shipyards
For shipbuilding, the double girder gantry crane are widely used which are to lift extremely heavy loads..They can be used to transport large ship parts and components from the production site to the ship, such as the engine or fuel tanks. For one shipbuilding platform, serveral dozen of lifting cranes may be needed at the same time.
Warehouses
7.Various types of gantry cranes, ranging from light duty single girder cranes to heavy duty double girder cranes, can be used depending on the size and weight of the cargo. Small gantry cranes on rollers or castors can also be used to handle loads freely without the requirement for tracks or rails.

Construction
Portable gantry cranes are popular in the construction industry because they are easy to disassemble, load, and relocate to a new position. They can be used to move and lift a variety of items, including small concrete blocks, steel girders, and lumber. Construction on a large scale, on the other hand, necessitates heavy-duty overhead gantry cranes with double or single girders. They can be used to move huge loads vertically to almost any location on a construction site.

Shipping Docks, Airports, and Railway Yards
Heavy-duty gantry cranes are also used to lift huge containers at shipping docks (or ports), airports, and railway yards. In these locations, mobility is quite important. As a result of its capacity to maneuver while carrying huge loads, rubber-tired gantry cranes are in high demand in train yards and seaports.
