General instructions for loading, unloading and manipulating Unic Rotarex® steel structures


is done manually, mixed or totally mechanized by adequate machinery and devices: slide bridge, forklift, crane or other devices specially designed in this scope.
1.1 Manual loading and unloading is done when the various types of packs do not allow grouping on lengths or similar shapes in order to position them on top of each other or next to each other by mechanized means.
1.1.1 Packs will be manipulated on the width side vertically. Meaning that each pack has a minimum of 3 dimensions: height (smallest dimensions), width (medium dimensions) and length (biggest dimension).
1.1.2 In the transportation mean and in the stack, the pack is stored with the height in a vertical position by turning the pack at the same time from width to height.
1.1.3 Each pack that is longer than 3m will be manipulated by 2 or more handlers.
1.1.4 Each pack that is longer than 6m will be manipulated by 3 or more handlers.
1.1.5 The handlers must be positioned at equal distances between each other.
1.1.6 The length of the pack is divided to the number of handlers + 1, thus determining the distance between handlers.
1.1.7 First and last handler are positioned at half an interval from the pack ends and the rest at one interval.
1.1.8 Positioning and lifting in and from the transportation mean is done carefully so that bending or tearing of the pack does not occur.
1.1.9 When unloading teams equal in number (minimum one in the transportation mean and one outside) transfers the grip of the pack from one to the other so that the number of handlers and position of the pack to be as mentioned above.
1.2 Totally mechanized unloading is done only when the loading was mechanized and the Seller notifies the Buyer in advance about this possibility.
1.2.1 If it is decided in the agreement that the unloading will be totally mechanized the Seller will provide further special unloading instructions to these instructions.
1.2.2 In normal conditions side lifts with transportation platform can be used. This device allows unloading of the packs that do not exceed the dimension of the transportation platform by more than 2 meters on each side of the platform.
1.2.3 Forklifts with wooden pallets can be used as a lifting device to unload the packs that do not exceed the length between the forks and 2 meters on each side. Transportation with this king of forklift is not recommended because of the high risk of take-offs of the stack by lateral balance.
1.2.4 Mechanized unloading can also be done by crane by tying loads with straps at maximum 2m distance. This means that for loads longer than 4m the load must be lifted with a rigid bar positioned between the hook of the crane and load, from which the straps that hold the load will be attached. Distance between straps will be maximum 2m and all straps will be adjusted equally between load and the lifting rigid bar. It is recommended that the load is tied with straps around it to prevent take-offs of the packs when the crane is maneuvered.
1.3 Mixed loading and unloading is done combining instructions from manual and mechanized.
1.4 The use of traction cable, chains or other materials that might scratch or damage the galvanization layer is forbidden.
1.5 Wrong manipulation of the packs, bulk unloading, throwing, crawling or other maneuvers that can lead to damage of the profiles or/and of the galvanization layer is forbidden.


2.1 Tying of the goods in the transportation mean is done by the Transporter with enough adequate textile straps to secure the goods during transportation so that the goods will not move, incline or take-offs;
2.2 The Seller loads, positions and adjust the position of the good at the request of the Transporter;
2.3 At unloading the Buyer will unload the goods only after the Transporter unties the textile straps.


is done on a plane, dry and clean surface.
3.1 Direct storage of the packs on the ground is forbidden. Stacks are separated with wooden spacers of minimum 15cm (the ones in direct contact with the ground) and minimum 10cm between stacks.
3.2 Dimensioning of the stacks is done taking into consideration the capabilities of the loading/unloading devices or are dimensioned with more spacers so that the stacks are stable.
3.3 Height of the stacks is decided ad-hoc in relation to the stability of each stack by adding on vertical direction. Stacking is done on the handler r
3.4 Short term stacking (maximum 30 days) can also be done outside following the following rules
3.4.1 Stacks must be inclined by minimum 5-6 degrees, to allow raindrop or condensation between profiles to drain.
3.4.2 Stacks must be small and well ventilated with a distance between them so that good ventilation will allow water droplets to dry.
3.4.3 Short term storage is forbidden if between profiles is forming a water film that does not dry immediately after rain or condensation.
3.5 Long term storage (over 30 days) is done in covered spaces, that lacks humidity, well ventilated, on a slight inclined planar surface to allow condensation drain.
3.6 It is forbidden to cover the stacks by plastic foil or other materials that might prevent ventilation and draining in case of condensation.
3.7 It is forbidden to store the goods in high humidity or corrosive environments.

4 Work safety

4.1 Loading, unloading, manipulation, transportation, and stacking of the packs containing Unic Rotarex® structures is done by following all standing safety norms at the time of the action.
4.2 Always use protection glows and clothes when you work with the steel profiles.
4.3 Avoid contact with the sharp edges and corners.
4.4 When unloading from the transportation mean make sure that the good did not move during transportation and it will not move or fall to hurt you.
4.5 Do not stack very high as steel profiles are slippery and stacks might overturn.
4.6 Make sure that the lifting devices are strong enough and are correctly fixed.


5.1 According to the standing law, all companies have the obligation to conduct the reception of the goods received from suppliers. Individuals have the obligation as well to make the reception of the goods.
5.2 The reception is done by a reception committee made of 3-5persons with the following attributes:
5.2.1 conducts the qualitative and quantitative reception
5.2.2 follows the evolution of goods during storage.
5.3 The reception committee verifies each lot of products (same type products, produced using the same raw materials, using the same technological procedures, having the same destination, same shape, same production date). The reception committee does quality verification based on standing standards, that include quality characteristics, classification of the defects as well as the procedure that must be followed in case defects are observed. According to the verified characteristics, the lot is declared suitable or not suitable, thus accepted or not accepted.
5.4 At reception from Transporter make sure that the goods are compliant with the order and that the delivery contains all packs found in the packing list.
5.5 Quantitative reception means receiving the structure by weighing, measuring, counting. This means:
5.5.1 presence and accuracy of the info written on the sticker – confronted with the packing list;
5.5.2 verification of the material lot – confronted with the assembling plan;
5.5.3 verification of the integrity of the packs – number of ties are verified and their tightening;
5.5.4 verification of the presence of the packs – by ticking on the packing list;
5.5.5 verification of the presence of the profiles – confronted with the assembling plan;
5.5.6 verification of the presence of the screws and assembling accessories written on the packing list;
5.6 Qualitative reception: means verification of the properties of the structures. This stage means:
5.6.1 visual inspection of the packs – packs must not show deformations, scratches or rust sports;
5.6.2 verification of the shape of the profile;
5.6.3 verification of the thickness of the galvanization layer;
5.6.4 verification of the thickens of the steel;
5.6.5 verification of the print on the profiles – one side is printed with the name of the producer “” and the lot number of the steel written in the project documentation. The other side of the profile is printed with the assembling code that contains the element and is read according to the assembling instructions.
5.6.6 Verification of the presence of operations on profiles: cuts, bending, pre-drilling.
5.7 Verification of the documentation:
5.7.1 agreement documents (agreement and annexes to the agreement);
5.7.2 documents that accompany the goods, delivery documents (invoice, packing list);
5.7.3 transportation documents (CMR, road schedule);
5.7.4 quality documents: quality certificate ZA 3.2 or 3.4: document released by the producer that proves the quality of the product; in this document it is mentioned the tests and proves that the product has been tested according to standards, technical norms or other clauses mentioned in the agreement; Declaration of performance; Quality certification; Warranty certification;
5.8 Reception report is done after actual verification of the quantities, quality, and documents. The reception committee interprets the results and decides to accept or to deny the goods.
5.8.1 The results of the verification of the quantity and quality of the lots are written in a report This report shows the real quality of the goods. Based on the report the real quality of the goods is compared with the prescribed or agreed quality and can be inferior or sometimes superior.
5.8.2 The reception report represents the proof of the conclusions done by the reception committee and can be invoked by the Seller, Buyer or Transporter. It is proof that includes the following: date and place of the reception; composition of the reception committee; methodology used for quality verification; observed qualitative deficiencies; causes of the observed qualitative deficiencies (transportation or poor packaging, technological process).
