Pillar jib crane with a 270° angle of rotation and manual slewing KKR2
- boom (console) of the crane — 1 pc.
- crane column with lower support flange — 1 pc.
- power supply to the crane (in case of delivery of the crane with this option and the presence of any electrical equipment in the crane (for example, hoists)
- power supply to the hoist (in case of delivery of the crane with this option)
- other parts (the list of components depends on the configuration and set of options of the crane you ordered and may differ from the one given in this section of the site)
- crane documentation (passport, crane operation and installation manual, passports and instructions for individual crane components manufactured at other enterprises and supplied with this crane, packing list, waybill).
The above configuration is basic and may differ significantly from the actual one. If you need complete information on this issue, please contact the nearest sales department.
| Name of the option | Description of the option |
| Load capacity limiter | It is used as an additional safety device along with limit switches and a load drop protection device in case of phase breakage. It is installed, as a rule, in cases where work is carried out with different loads, the mass of which is not always known. If the weight of the load exceeds the lifting capacity of the hoist, the limiter blocks the lifting process. The option is available for cranes equipped with an electric hoist, since the limiter is mounted on the lifting mechanism of the hoist. |
| Carport for parking hoists when performing "On the street" | They are used on cranes of the placement category U1 (on the street) to protect the electric hoist from direct precipitation. It is recommended for installation by manufacturers of cranes and hoists, since the hoists themselves usually do not provide alternative protection from precipitation. |
| A canopy for a hoist for the entire length of the span when performed "On the street" | They are used on cranes of the placement category U1 (on the street) to protect the electric hoist from direct precipitation. It is recommended for installation by manufacturers of cranes and hoists, since the hoists themselves usually do not provide alternative protection from precipitation. |
| Electric limit switches for the movement of hoists along the crane boom | They are used to limit the path of the electric hoist along the crane console. |
| Anchor system for fixing the crane to the foundation | This option refers to the stage of installation of the structure. Anchors are needed to attach the crane to the foundation. As a rule, we offer an anchor system for implementation on a prepared foundation. On an unprepared foundation, so-called mounting studs are used. |
| Platform and ladder for maintenance of hoists and crane components | When ordering a jib crane with a height of more than 3 meters, it is recommended to immediately provide ways of servicing the hoist, oil change and other maintenance operations. One of the options is to install a horizontal platform on the column at a human-height distance from the console and a ladder welded to the crane column leading to this platform. |
| Rigid removable/non-removable stops for limiting the angle of rotation of the boom | Rigid removable /non-removable stops for limiting the angle of rotation of the boom are used mainly for jib cranes KKR3 and KKM7 to adjust the angle of rotation of the console. They are installed on the ring that wraps around the crane column. Two rigid stops limit the angle of rotation of the boom in both directions. On wall-travelling cranes, the stops are welded to the crane boom and can provide only 1 option for the angle of rotation of the boom. |
Pillar jib crane with a 270° angle of rotation and manual slewing KKR2, design and operation features
- It is used for lifting and moving any cargo weighing up to 16.0 tons
- It is an arrow on a column with a lifting mechanism attached to it, rotating around its axis at an angle of up to 270 degrees. The restriction is provided by attaching the crane boom to the column from the side
- It is mounted on a concrete foundation by means of a support flange and anchor bolts
- The crane consists of a console (boom), a column, an electric or manual hoist
- Turning the boom of hand cranes is carried out by means of a drawbar, lifting, lowering the load either manually or with the help of an electric mobile hoist and a control panel
- The mechanism for lifting and moving the load is a hoist (tal), which moves along the boom of the crane
- To increase the reliability, security, and convenience of operation, we recommend installing additional options
- The advantage of jib cranes over overhead cranes is the convenience of working in a limited working area, ease of installation, no need to provide crane tracks
- Jib cranes are often used for operation on the street, outside the premises, which increases the scope of their application.
The advantages of the KKR2 manual slewing jib crane include its ease of installation and use, high performance and durability. The cost of this lifting device directly depends on its configuration, overall dimensions and technical and operational characteristics.
The main working element of a jib crane with a manual drive is a rotating console, which is mounted on a column and equipped with a hoist that acts as a lifting mechanism. The column is mounted on a reinforced foundation and additionally secured with chemical or metal anchor bolts. The angle of rotation of the console is 270 degrees due to the installation of rigid stop-limiters of the angle of rotation of the console. A pillar jib crane with a 270° angle of rotation and manual slewing KKR2 is able to cover almost the entire area of the workshop or warehouse, moving cargo, including to the most inaccessible places. The length of the boom departure, the lifting height and the lifting capacity are determined at the stage of development of the working project before the production of this lifting device.
The service of manufacturing a manual jib crane KKR2 with individual technical parameters and full compliance with GOST is offered by many domestic manufacturing plants in general industrial, fire-proof and explosion-proof design. Our company is one of the leaders in the production of jib cranes in Russia and guarantees the safe operation of the crane throughout its entire service life (at least 30 years). In addition, this lifting device can be equipped with special devices that increase its productivity, expand the scope of use and ensure its safe operation both in closed rooms with natural or artificial ventilation, and in open areas. When ordering the manufacture of a crane in a special design, it is possible to operate it in an aggressive environment at extremely low or extremely high air temperatures.
