HDS cranes

Mobile cranes, otherwise known as transhipment or hydraulic truck cranes (HDS), have been on the market for a long time, but have only become popular in recent years. They belong to the group of cranes and are arrangedami used for unloading and loading various types of goods. Unlike other cranes, they can reach almost any place due to their compact design. These machines are used in the transport and construction industry. They own drive mechanical,y composed myself With rotating columns on the base, and boom system located myself at the top of the column. Loading cranes may be assembled both on semi-trailers and on vehicles. They are often used on tractor units to facilitate the transport and unloading process. They are classified as portable cranes and are subject to the regulations of the Office of Technical Inspection. 

Due to the different design adapted to individual industries, portable cranes / reloading cranes are divided into: 

  • reloading at the rear of the vehicle with a transfer box 
  • reloading services in the middle of the vehicle 
  • reloading mounted behind the driver's cabin,  used in companiesah transportch 
  • general purpose with chassis structure z liftoh operating horizontallywhich job depends on lifting and lowering loads 
  • used in the wood industry equipped with special grippers instead of the standard hook 

 

Application: 

  • transport of building materials at heights 
  • in the wood industry for loading and unloading trees 
  • transport of sea containers 
  • unloading and reloading of industrial containers in warehouses 
  • stacking pallets on higher storeys 
  • on smaller areas at construction sites, where it is not possible to use heavy equipment 
  • transport building materials on pallets 

 

Construction of an HDS crane 

HDS cranes consist of permanent structural elementswhich are their indispensable equipment and parts variables that are inexchanged depending on vperformed washyto whichhey given crane left adapted. 

 

Fixed elements: 

  • the crane's stabilizing supports, as well as the vehicle on which it is mounted, balance the increased weight of the crane 
  • column attached to the base - it happens that it has a telescopic system that facilitates lifting work 
  • the base on which the crane is located - it never changes regardless of the scope of the work performed 
  • adjustable boom for carrying loads, which is one of the most important elements of the entire HDS device, because it enables work even in the most inaccessible terrain 

 

Variable elements: 

  • grippers used instead of a hook, incl. in the wood industry 
  • hook used for gripping and carrying loads 
  • hydraulic system installed in lifts used on construction sites and in warehouses - improves the crane's work 

 

The variable parts of the crane can be adapted to the current work of the device. Some examples are: 

  • the hook can be installed to carry large and heavy loads - the realization of this task is based on the use of a rope system 
  • a gripper, which is an alternative to the hook - used in difficult tasks when it is necessary to suspend various parts with ropes or slings; copes with irregular shapes 
  • a hydraulic system that can be used to efficiently unpack the equipment; the important advantage is that it is precise 

How often it should to carry out HDS maintenance? 

Maintenance of the HDS should be timelyie specifiedm in the operating manual of the device.  

It is important to follow its provisions. There are three types of examinations: periodic, operational and post-accident examinations. Periodic inspection is determined in accordance with the date specified for a particular type of crane. The technical condition of the drive mechanisms, load-bearing tendons, as well as their fastenings and braking systems is checked by a conservator. The inspector of the Office of Technical Inspection should check the qualification certificates of the maintenance person and the HDS operator, the electrical measurement protocol, the maintenance log, as well as the inspection book. In addition, it specifies the scope of operational tests depending on the reason for the inspection, e.g. modernization, repair or replacement of elements. 

Another thing is to check control, lighting and signaling devices, as well as movement stops and safety components. It is recommended to check the fire protection system and the supporting structure once a year. In order to prevent faults and malfunctions of the HDS crane, perform a maintenance inspection on a regular basis. Post-failure (accident) tests are carried out when there is an accident or damage to the device. 

 

What is iny HDS operator remuneration? 

The earnings in this position can vary a lot. The employee's experience and the specificity of the company should be taken into account. The salary may vary between PLN 2,400 - PLN 4,000. However, when considering working abroad, we can count on € 50 to € 70 per hour. 

 

What qualifications must have HDS operator?  

A person who would like to work as an HDS operator must obtain the appropriate qualifications, which are granted after a specialist course at HDS, where participants are prepared to properly operate the devices while adhering to all health and safety rules. During the training, practical exercises and theoretical classes are conducted, where you can learn about the construction of machines and other knowledge that may be useful when you start working as an HDS operator. Course ends with a professional exam, which takes place before the committee of the Office of Technical Inspection. Only the passing of the state exam ensures the right to operate HDS cranes. People interested in the course must meet several conditions, i.e. be at least 18 years old, have at least basic education, a category C driving license and no contraindications to work as an operator confirmed by a doctor's certificate. Reports show that construction workers with HDS qualifications are one of the most desirable professional groups. 

 

HDS cranes can be used both outside and inside halls or buildings. However, it is worth remembering that the rooms must be properly air-conditioned due to the risk of poisoning by exhaust gases. In gusty winds or storms, and when visibility is poor, stop using the machinery. Before starting work, the operator of the machine should always make sure that there is no risk of a security incident. During the work, he must comply with all health and safety rules and remember to use appropriate personal protective equipment.
