Course in qualificationsWarehouse stacker cranes are a tool that facilitates the storage of materials. They work by moving along the racks located in the warehouse. They are very efficient machines that can considerably speed up the process of loading goods. Nevertheless, such complex machines require special checks at regular intervals, which can only be carried out by authorised personnel. Like many advanced machines registered with the Office of Technical Inspection, the stacker cranes also require their own inspections and maintenance work. In order to carry out these works, a person is required to have the necessary authorisations. UDT of these stacker cranes. They are a very effective tool and bring many advantages of use such as:

  • automatic loading and unloading, without the need for employee intervention,
  • carrying out checks and updating the stock held,
  • simplicity in maintenance and operation of the unit,
  • the absence of mistakes that could arise from manual work performed by humans,
  • well coordinated operation and smooth movement of the device

If we consider the type of control of the stacker cranes we can distinguish:

  • automatic control,
  • semi-automatic control,
  • manual control.

Stacker cranes use the following instruments to move and retrieve goods:

  • pitchforks,
  • grippers,
  • conveyors

Warehouse stacker cranes also differ in construction, so they can be divided into:

  • Column stacker cranes - built in the form of a mobile pole,
  • frame stacker cranes - constructed in the form of gantries running along the shelf

These machines are powered by an electric drive and have their own microprocessors, so that no human intervention is needed for their operation. The stacker cranes can handle one aisle as well as several. Knowledge of the operation, design and materials of the stacker cranes is essential in order to perform maintenance work on these machines.

UDT authorisation for stacker cranes

Warehouse stacker crane during loadingThe way to obtain specialised UDT qualifications is by passing the relevant operation and maintenance courses. Many companies offer their employees just this type of training consisting of theoretical knowledge and practical exercises. If the boss wants his employees to be certified to carry out maintenance work, he can take advantage of one of the many offers from companies providing such training. In addition, at the end of the learning process, it is necessary to take an examination in front of an assembled committee, and only if the result is positive does it become possible to grant the authorisations of the Office of Technical Inspection. Stacker cranes must be subjected to various types of tests from time to time, and to be able to take them at all, the machine must be:

  • properly assembled and constructed,
  • technically sound and in perfect working order,
  • ready for operation under pre-defined conditions

The conditions that must be met for the study to take place are:

  • good lighting and unobstructed visibility,
  • no health hazards or exceeded low or high temperature limits

During the conduct of the research, the following must be present:

  • operator,
  • the person responsible for maintenance,
  • operator,

And it is at this point that the conservator is required to present the required authorisations to participate in the tests. Equipment is subject to tests such as:

  • periodic - the timing of the tests depends on the type of equipment and is different for everyone,
  • ad hoc - in this case, the timing of the examination depends on the individual needs of the employees,
  • post-accident or post-failure - as the name suggests, these are carried out after some mishap or detected technical failure.

The role of maintenance

As you can see, keeping these types of tools clean, accident-free and operational is not the easiest thing to do. However, maintenance work backed up by proper testing from time to time allows these machines to operate safely and efficiently. It is very important that there are properly trained people in the workplace with the unquestionable authority to do just this type of maintenance work. If you or your employees have plans to develop in the industrial sector with loading and unloading work, they should attend a special UDT training course. This prepares you to obtain specialised certificates from the Office of Technical Inspection and will streamline the whole process of your company. The choice of offerings is really wide, and it is up to you to decide on the final training course.
