Gantry cranes - description, general specifications

The gantry crane is a bridge type unit.

The horizontal beam along which the load moves is structurally related to the bridge group of lifting mechanisms.

Application and arrangement of QC

Gantry lifting mechanisms are indispensable in places where the entrance of the rest of the lifting equipment is problematic or excluded.

Occupying a minimum of space on the ground, the unit covers a large area for moving goods.

Application:

warehouse and industrial territories , cargo yards;
factories - polygons for the manufacture of metal structures, reinforced concrete products (KKM-20);
transshipment of containers at freight stations, railway junctions, seaports (КК-16/20);
work with logging , wood (LT-62);
installation of prefabricated industrial structures and equipment (KK-12.5);
maintenance of locks , dams, thermal and hydroelectric power plants;
in the ship - and shipbuilding (production of large ships, fixing parts of the hull during welding).

Gantry lifting mechanisms are equipped with those load grippers that correspond to their purpose.

The operation and maintenance of the KKS-10 crane is prohibited in places where combustible or explosive substances are stored.

Work restrictions :

the boundaries of the working area - the space inside the console (span);
KK cannot be used on slopes.

The general scheme of the gantry crane with a description :

crossbar (truss, beam) - span structure.
The bridge of light and medium CC is single-block, heavy - two-block. The beam can be lattice or solid-walled of different sections. It may have 1 or 2 consoles, or not have them at all (console and non-console cranes);
supports - rigid, spatial, flexible or flat. If the spans are <25m, then all the supports are rigid, with undercarriages fixed at the bottom of each. With large distances between the rails - one leg is fixed rigidly, and the 2nd is hinged. Each support includes 1 or 2 posts;
crane ( cargo ) carts (or electric hoist) equipped with a lifting mechanism on which the load is attached. Cargo trolleys are either monorail or double rail. Double-rail carts move along both belts - upper and lower, and single-rail - only along the lower one;
electrical equipment . The power supply of the KK is from the external network via trolleys or using a flexible cable. The cable is wound onto a cable drum fixed on one of the crane supports;
crane rail tracks - ground, R43 / R24 (R50 / R65) rails are installed on wooden (reinforced concrete) sleepers on a gravel pad. The rails must be with grounding and dead ends. Movement is due to double-flange wheels mounted on supports. The track size is equal to the span of the crane.

In addition to structural elements, the gantry crane device includes mechanisms for moving the entire crane and trolley, and a lifting mechanism.

The function of lifting the load is carried out by a cargo trolley (w/w>5t) or a hoist (w/w<15t).

It is possible to combine a cargo trolley with an electric hoist on one mechanism - work with heavy loads is carried out from the trolley, and additional work of lesser severity is carried out with the help of a hoist.

All runway gantry cranes have anti - theft grippers designed to keep the heavy and tall hoist from falling when subjected to wind loads . _ _

Classification

According to their purpose, CC can be divided into 3 groups:

general purpose - reloading, used for loading / unloading various cargoes in open production / storage areas and indoors such as hangars, load capacity = 3.2-50t;

construction and assembly : assembly of industrial equipment, shipbuilding, installation of large-sized concrete products, supports and trusses of bridges, capacity = 300-400t.

Both categories are mostly equipped with hook suspension, span length = 8-80m, lifting height = 7-30m.

special : shipbuilding, hydroelectric power station, thermal power station, maintenance of dams, locks. They are equipped with special grippers: grabs, electromagnets, pincer grips, additionally mechanized with a mounting boom, a jib crane, etc.

Special cranes of large standard sizes are produced, which can be calculated together with the project of the structure being built, for example, a hydroelectric power station or a bridge.

Carrying capacity - up to 900t, span - up to 130m, lifting height - up to 80m.

Gantry cranes are self-erecting , the rest are mounted using special equipment.

Different standard sizes of KK are produced, the models have a wide range of technical parameters:

lifting capacity - from 5 to 1600 tons;
lifting height - from 3 to 100 m;
spans - from 20 to 130m;
lifting speed - from 0.1 to 32m/min;
movement of cranes - up to 100 m/min, trolleys - up to 40 m/min.

By carrying capacity all models can be divided into 3 categories :

5-10t;
12-50t;
Cranes with bolt prestressing, with lifting capacity from 15 to more than 50 tons.

Preferred applications are gantry cranes with flexible load suspension - hook , as well as clamshell (KKTGK) and magnetic (KKM).

Some models have the possibility of lengthening the crossbar and supports due to inserts. This allows you to change the payload from 15 to 50t, the span from 32 to 62m and the lift height from 7 to 30m.

About other lifting mechanisms on the site: truck cranes Liebherr, Ivanovets 25, Galichanin 25, truck crane based on MAZ-5337, Tadano manipulator, pneumatic wheel crane KS-5363, crawler cranes MKG-25BR and RDK-250, tower crane KB-403 and details about overhead crane device.

Control

You can control the lifting and movement of KK cargo from the ground or from the cab.

The electric method is from the crane operator's cab. From a height, cargo of any size is clearly visible, the cabin can be equipped with an on-board computer for more accurate placement of cargo.

Mainly used for lifting capacities >10t and requires an experienced crane operator.

Operation of KKS-10 at temperatures below -40ºС is prohibited: • lubrication of units thickens; • Moisture particles that get on the rubbing surfaces freeze, causing serious damage during operation.

Cranes with this type of control are registered with the technical supervision authorities without fail. The cab of the crane operator can be stationary or mobile .

The fixed one is attached to one side of the crane and is recommended for small spans and lifting heights.

The mobile cabin is mounted to the mobile crane trolley, which is convenient for long spans and lifting heights.

control the process from the ground using a wireless or pendant control panel. This method is more often used indoors with small dimensions of cargo, having a sufficient view from the floor.

Remote control of the mechanism does not require additional education of employees.

For gantry cranes without a cab with a lifting capacity of up to 10 tons registration with the technical supervision authorities is not required
