Automation of lifting and transport mechanisms

Transportation of equipment, parts, components is one of the simple but very important operations at production sites. Lifting cranes for spatial movement of different loads are used for this task. In order to ensure their optimal and durable operation, automated control is required, which is achieved by means of special devices for converting and transmitting signals, energy and monitoring processes.

Why do you need to modernize your cranes?

A stable production rhythm cannot be ensured without quality inter- and intra-shop transportation. In addition to its primary function, radio control of the crane allows:

Increase the productivity of equipment in the context of speed and accuracy of operations, which will reduce the number of equipment and personnel;
Simplify the control of tower cranes and other hoisting and transporting mechanisms, and thus facilitate the task of the crane operator at the console;
Strengthen the reliability of equipment, extend its service life.

After the implementation of a comprehensive crane radio control system, the task of maintenance personnel will be reduced to monitoring the system only. Therefore, entrust this responsible task to an expert in the automation of industrial and infrastructure facilities – the company “INFOCOM sp. z o.o.” in Kiev.

For more than 22 years of practice we have managed to raise the crane radio control to a new level, so we offer our clients not only modernization of hoisting and transport mechanisms, but also specialized solutions for specific tasks with a guarantee of reliability, stability, full control.

Features of the radio control system of cranes INFOCOM Sp. z o.o.

We install a complete control system on the bridge of truck crane, grapple, bridge, traverse, devices. Our engineers offer several variants of cabinets based on models of leading world manufacturers, which have protection level not lower than IP54 (excellent protection against dust, water splashes), can be additionally heated or cooled.

There is also an option of placing the equipment in an electrical room. The ready-made solution is suitable if the working conditions are quite difficult (high dustiness, gassiness). Additionally, there is an option of lighting, air conditioning, heating of the room.

The crane radio control system controls the crane itself, the cart of the slewing or non-slewing type, and the crane lifting. Separately we offer special solutions: anti-sway, anti-collision and weight measurement systems. More information is available on our website or after consultation with certified engineers.

Using the remote control kit developed by INFOCOM sp. z o.o., you will get additional benefits:

reliable operation in all weather conditions, regardless of the season;
minimal need for maintenance;
simple, convenient, ergonomic operation;
smooth operation, precise control.

In addition, we take into account the environmental parameters and the conditions of the lifting and transportation work. For example, high or low temperatures, high levels of dust or gases in the air.

Thus, the remote control kit is the optimal solution for controlling material handling equipment. Order a service from INFOCOM sp. z o.o. and we will become your reliable partner in the field of automation!

Crane control system

The control system of the crane includes the following main functions: control of the main lift (boom control), boom rotation, trolley control, crane movement control, grab control (if the grab is not electric, where the automatic closure of the grab is adjusted when lifting).

Additional functions of the crane control system

As additional functions, special features are considered, such as cargo positioning systems (very important in ports for placing container cargoes), cargo counter-dragging system, a crane skew control system, an anti-collision system (accommodation and motion control of two or more cranes on one bridge), weight changes (weight control during overload). This functionality is performed at the request of the customer.

Control equipment placement options:

in the cabinet assembly (the crane control system is located on the crane bridge in the cabinet assembly). Constructive cabinet assembly is carried out on the basis of cabinets from leading European manufacturers, the coating is durable powder coating, protection of the cabinet design is not lower than IP 54. In addition, cabinet assemblies are completed with heating and air conditioning.

Radio control of crane

Radio control of crane is a remote control of a hoisting-and-transport mechanism using radio signal to equipment (basic equipment always consists of a receiver, a module for controlling a crane and a radio transmission unit and a control panel). The control panel, in its turn, can be presented as a joystick, an apparatus with buttons or a programmable logic glove. Thanks to transmitter power up to 5mW (and operating frequency bands from 415 to 483 MHz), such remote systems can be used without special permissions – this is a requirement to ensure safety when operating remote control systems.

Radio control is currently more a necessity than additional functionality for a crane control system, when there is an opportunity for the crane operator to be on the foot (especially if the lifting height of the load is large, and there is a need to perform precise operations quickly).

With the help of remote control systems, it becomes possible not to use the operator’s cabin and suspension consoles and to control the lifting-transport mechanism at any convenient point of the device’s operating radius. This is true for limited space accommodation crane beams (there is no place to accommodate the cabin).

The main advantage of the remote control system is a small device mass, ergonomics, low transmitter power and a large radius of application. To ensure the safety of the crane operator, it is possible to adjust the crane operation zones and monitor the location of the crane operator, so that when the crane operator is in the danger zone, an auto-stop of the load lifting mechanism can be done.

Advantages of remote control of the crane:

The overview of the crane operator is not limited to the cab, so the location of the cargo can be determined more accurately;
There is an opportunity to choose the best and safe points of work with cargoes;
It is easier to train personnel to work with a remote control system;
Allows any personnel to learn and work as a crane operator without having a separate crane operator position.

Anti-collision system

The anti-collision system is an additional functionality designed to monitor the location of gantry and bridge cranes, loaders and other equipment that runs on one track.

The system is based on ultrasonic displacement sensors, allows you to set up warning and dangerous distances between objects moving in the same axis, thereby ensuring the safety of equipment and safety of the process.

Weight measurement system

The weighing system is a ready-made solution for measuring transported loads with data output on an external display and transmission of information to the operator’s station.

The system is based on weighing cells and Siemens Siwarex measuring modules for the S7-300 controller.
In the system it is also possible to compensate for the weight measurement error by taking into account the measurement of the length of the cable.

Anti-jump system

The anti-skid system is a system for controlling oscillations, swinging of the load, caused by acceleration and deceleration processes.

Thus, all cargo oscillations are controlled by a vibration prevention system. This solution is designed for cranes operating on an open trestle and port cranes. Based on software Siemens Simocrane SC / Simocrane CeSAR.

When using the anti-skidding mechanism of the crane lifting mechanism, the crane operator is relieved of the constant impact on the load in order to balance it, and can directly focus on lifting, positioning and lowering the cargo.

The anti-recovery system of the crane lifting mechanism autonomously monitors the deviation from the ideal position, monitors the trajectory of movement and calculates the speed required for the adjustment.

Electrical room

The electric room is a ready-made solution for placing the equipment of a crane control system in a separate mobile electric room.

Depending on the environmental conditions of the crane (dust, gas, temperature, etc.) for ease of maintenance and durability of the equipment used in the electric room, in addition to the main equipment of the control system, air conditioning, heating systems, lighting systems can be provided.

In the spring of 2019, INFOCOM sp. z o.o. for the Kharkiv Material Handling Equipment Plant LLC produced a special bridge crane KM 1648 ACS Container, with a lifting capacity of 16 tons.

The container is designed to accommodate the bridge crane control system. The system is based on the Siemens PLC of the S7-300 series and frequency converters of the Sinamics S120 series. The equipment is placed in the container on the panels installed on the vibration mount to prevent the effects of unwanted vibration when the crane is operating.

He necessary microclimate is maintained in the container to ensure the correct functioning of the control system, even when used in metallurgical workshops with high thermal radiation. When designing a container, a solution is provided to prevent the ingress of dust into the container (including conductive) in rooms with high dust levels.
