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. |
Sound and light alarms | The alarm is activated when the jib crane is turned on, warning employees to leave the danger zone. Depending on the conditions of the working area, it is recommended to install a light or sound alarm. The option is available only for electric jib cranes. |
Radio control | Allows you to control the crane from a distance using the remote control. The option is available for electric jib cranes or for cranes equipped with an electric hoist. The package includes a 6-button remote control with an emergency stop button, a radio signal receiver (installed on the hoist or on the crane control box or next to the control box). |
Electric motor with boom turn brake | The built-in brake allows you to stop the crane boom in the right place of non-stop movement of the equipment by inertia. It is impossible to manually fix the console at a strictly necessary point. Visually, the brake on the crane structure is not visible, since it is an element of the gearbox motor design. The option is recommended to be installed for cranes with the placement category U1 and U2 to prevent spontaneous movement of the boom in the parking position with wind gusts and other external factors. |
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. |
Power off on the crane column | Allows you to turn on/off the tap power. It is located at a height of about 1500 mm from the lower flange of the crane. It is a two-button post in a protective (metal) casing. |
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. |
Load drop protection device in case of phase breakage | An additional safety device along with a load capacity limiter and limit switches. |
Logger of crane operation parameters | Registers the operating conditions of the crane, including modes, duration and volume of loading. It is installed only when the crane is equipped with an electric rope hoist. |
Crane operating time indicator | Controls the operating time of the crane, allowing time to carry out the necessary maintenance, maintenance and overhaul. It is built either into the door of the crane control box, or inside it. |
Frequency control of the boom rotation speed | The frequency converter is installed in the crane control box for the possibility of adjusting the boom rotation speed in a certain range. It can also perform smooth start and braking. |
Engine cooling system | It is recommended to use when installing a frequency converter, which will significantly limit the standard speed of movement of the crane, to prevent overheating of electric motors. |
Input throttle | Smoothes the front and reduces the amplitude of the emission of bursts of alternating power supply voltage. Reduces the amplitude of the ripple current consumed by the frequency converter from the mains. |
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. |
Heated crane control box | Allows you to operate a jib crane at air temperatures up to -20 g. C (inclusive). It is required to be installed on all cranes that are operated at an air temperature below -10 g. s. Requires additional installation of a frequency converter. |
The Pillar jib crane with a 270° angle of rotation and the electric slewing drive (KKM7) is a modern lifting equipment that is widely used in production workshops, seaports, cargo terminals and large storage facilities. Its main purpose is to perform loading and unloading operations of medium and high intensity. This device performs lifting and moving of goods over a short distance, usually within a single production shop or an open general-purpose warehouse area, using an electric drive. It can be used in closed rooms with natural or artificial ventilation, as well as outdoors or under a canopy, provided that the ambient temperature is between -20°C and + 40°C (on request from -40°C).
The plant "Gruzopodyem" manufactures electric jib cranes KKM7 according to the Technical Regulation of the Customs Union 010/2011 "On the safety of machinery and equipment" with a load capacity of up to 16.0 tons and a maximum boom reach of up to 12.0 meters. Our cranes are used both in small warehouses and on drilling rigs in difficult climatic conditions.
Pillar jib crane with a 270° angle of rotation and the electric slewing drive KКМ7, design and operation features
- It is used for lifting and moving any cargo weighing up to 16.0 tons
- 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, a gear motor, an electric hoist
- The crane boom rotates around its axis by 360 degrees
- The power supply is supplied by default using an electric cable, it can be ordered optionally in the delivery package
- The crane is controlled by a 6-button cable remote control with an emergency stop button. It is possible to install a radio control option for remote control of the crane
- The mechanism for lifting and moving the load is a hoist (tal), which moves along the boom of the crane. The load-handling body is a hook suspension suspended from a rope rope
- Depending on the operating conditions, the manager may suggest setting a number of 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 design of the KKM7 jib electric crane consists of a column mounted on a reinforced foundation, on which a console rotating around its axis is placed, equipped with a lifting mechanism (hoist). The crane is controlled from a remote control via a radio signal or a cable control panel.
Pillar jib cranes with the electric slewing drive are manufactured in accordance with the TR CU and other regulatory documents in force in our country in general industrial, fire-proof and explosion-proof design. It is recommended to order the production of this device with individual technical parameters, namely, the required load capacity, the length of the console departure and the lifting height. If necessary, it is possible to complete the pillar jib cranes with the electric slewing drive with additional equipment that increases its performance and ensures safety during operation. Its price, performance and scope of use depend on the technical parameters and configuration.
