Purpose of stationary and mobile jib cranes


A jib crane is a device that has been around for a long time. Some historians call the date of its appearance the Middle Ages, others attribute the invention of the device to the hands of blacksmiths. That is, it appeared many centuries ago and continues to be improved in our time. Some components and mechanisms of the device are made using higher quality and reliable materials. Electrical units and motors are widely used.

Design Features

The design of the cantilever rotary crane includes an I-beam console as a base. It is mounted on a special column, which is firmly attached to the foundation using specialized brackets. The working body is a beam and a boom with an installed gripping hook.

Main equipment components:


Jib crane

  • console;
  • Column;
  • support bracket;
  • rolling support;
  • traction chain, clamp;
  • stops, covers;
  • bearings, dampers.

The devices are manufactured strictly in accordance with regulatory documentation, therefore they have fixed technical parameters. The design of column-mounted jib cranes is regulated by GOST-19811-74, which contains detailed drawings and requirements.

Loads are moved vertically. The operating radius of the equipment depends on technical parameters: angle of rotation, boom radius.

Types of lifting consoles

Devices of this type are classified according to their mobility. The jib crane can be:


Types of jib cranes

  • stationary – fixed at the workplace and does not move;
  • mobile – such a device can move within predetermined limits.

The design of electric jib-slewing cranes can be equipped with manual rotation of the console. This solution allows you to use the equipment in places where there are no sources of electricity.

The wall-mounted design of the device is characterized by high reliability and performance characteristics. The mechanism is installed on the wall to move goods nearby.

Mechanical devices are controlled using a remote control. Both manual and mechanical variations are equipped with electric hoists or manual hoists. The latter option is used for relatively light materials. Hoists are designed to work with heavy objects.

Excerpt characterizing the Jib Crane

He stopped and rubbed his face and eyes with his hands. “Well, here,” he continued, apparently making an effort on himself to speak coherently. “I don’t know since when I love her.” But I have loved only her, only one, all my life and love her so much that I cannot imagine life without her. Now I don’t dare ask her hand; but the thought that maybe she could be mine and that I would miss this opportunity... opportunity... is terrible. Tell me, can I have hope? Tell me what should I do? “Dear princess,” he said, after being silent for a while and touching her hand, since she did not answer. “I’m thinking about what you told me,” answered Princess Marya. - I'll tell you what. You’re right, what should I tell her about love now... - The princess stopped. She wanted to say: it is now impossible to talk to her about love; but she stopped because for the third day she saw from Natasha’s sudden change that not only would Natasha not be offended if Pierre expressed his love to her, but that this was all she wanted. “It’s impossible to tell her now,” Princess Marya said. - But what should I do? “Entrust this to me,” said Princess Marya. “I know...” Pierre looked into Princess Marya’s eyes. “Well, well...” he said. “I know that she loves... will love you,” Princess Marya corrected herself. Before she had time to say these words, Pierre jumped up and, with a frightened face, grabbed Princess Marya by the hand. - Why do you think so? Do you think I can hope? You think?! “Yes, I think so,” said Princess Marya, smiling. - Write to your parents. And instruct me. I'll tell her when it's possible. I wish this. And my heart feels that this will happen. - No, this cannot be! How happy I am! But this cannot be... How happy I am! No, it can not be! - Pierre said, kissing the hands of Princess Marya. – You go to St. Petersburg; it is better. “And I’ll write to you,” she said. - To St. Petersburg? Drive? Okay, yes, let's go. But can I come to you tomorrow? The next day Pierre came to say goodbye. Natasha was less animated than in previous days; but on this day, sometimes looking into her eyes, Pierre felt that he was disappearing, that neither he nor she was any more, but there was only a feeling of happiness. “Really? No, it can’t be,” he said to himself with every look, gesture, and word that filled his soul with joy. When, saying goodbye to her, he took her thin, thin hand, he involuntarily held it in his a little longer. “Is this hand, this face, these eyes, all this alien treasure of feminine charm, will it all be forever mine, familiar, the same as I am for myself? No, this is impossible!..” “Goodbye, Count,” she told him loudly. “I’ll be waiting for you,” she added in a whisper. And these simple words, the look and facial expression that accompanied them, for two months formed the subject of Pierre’s inexhaustible memories, explanations and happy dreams. “I will be waiting for you very much... Yes, yes, as she said? Yes, I will be waiting for you very much. Oh, how happy I am! What is this, how happy I am!” - Pierre said to himself. Nothing now happened in Pierre's soul similar to what happened in it in similar circumstances during his matchmaking with Helen. He did not repeat, as then, with painful shame the words he had spoken, he did not say to himself: “Oh, why didn’t I say this, and why, why did I say “je vous aime” then?” [I love you] Now, on the contrary, he repeated every word of hers, his own, in his imagination with all the details of her face, smile, and did not want to subtract or add anything: he only wanted to repeat. There was no longer even a shadow of doubt as to whether what he had undertaken was good or bad. Only one terrible doubt sometimes crossed his mind. Isn't this all in a dream? Was Princess Marya mistaken? Am I too proud and arrogant? I believe; and suddenly, as should happen, Princess Marya will tell her, and she will smile and answer: “How strange! He was probably mistaken. Doesn’t he know that he is a man, just a man, and I?.. I am completely different, higher.” Only this doubt often occurred to Pierre. He also didn’t make any plans now. The impending happiness seemed so incredible to him that as soon as it happened, nothing could happen. It was all over. A joyful, unexpected madness, of which Pierre considered himself incapable, took possession of him. The whole meaning of life, not for him alone, but for the whole world, seemed to him to lie only in his love and in the possibility of her love for him. Sometimes all the people seemed to him to be occupied with only one thing - his future happiness. It sometimes seemed to him that they were all as happy as he was, and were only trying to hide this joy, pretending to be busy with other interests. In every word and movement he saw hints of his happiness. He often surprised people who met him with his significant, happy looks and smiles that expressed secret agreement. But when he realized that people might not know about his happiness, he felt sorry for them with all his heart and felt a desire to somehow explain to them that everything they were doing was complete nonsense and trifles, not worth attention. When he was offered to serve or when they discussed some general, state affairs and war, assuming that the happiness of all people depended on this or that outcome of such and such an event, he listened with a meek, sympathetic smile and surprised the people who spoke to him with his strange remarks. But both those people who seemed to Pierre to understand the real meaning of life, that is, his feeling, and those unfortunate ones who obviously did not understand this - all people during this period of time seemed to him in such a bright light of the feeling shining in him that without the slightest effort, he immediately, meeting any person, saw in him everything that was good and worthy of love.

Variation of cargo altitude characteristics

The lifting capacity of column-mounted jib cranes varies from 0.5 to 16 tons. Range of other characteristics:

  • boom radius, m – from 2.5 to 6 or 10;
  • lifting height, m ​​– from 2 to 4 or 5.

If the angle of rotation of the equipment is 240 degrees, the first numbers are relevant - the maximum boom reach is 6 m and the lifting height is 4 m.
