If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

The chain with its buckets is driven by a geared motor direct to the axle of the driving wheels, giving it a smooth, regular and silent movement. The bucket chain is made of hardened steel with high structural and wear resistance. The buckets are made of stamped sheet metal and the parts that are in contact with the clay are made of wear-resistant steel sheet. The internal driving wheels of the bucket-carrier chain are machined toothed with teeth, fixed by means of screws for their replacement, forming a 120° gear with three sectors.
The movement of the bar-carrier is carried out by means of two geared motors with a frequency variator, designed to work at two main speeds, one for work and one for fast. The elevation and graduation of the different positions of the boom with its chains and buckets is obtained by means of a hydraulic unit formed by two pistons, a central one and positioning encoders. These are commanded by a PLC cabinet programmed with all the relevant devices for the control and safety of all machine movements.

A corrente com suas caçambas é acionada por um motor-redutor direto ao eixo das rodas motrizes, conferindo-lhe um movimento suave, regular e silencioso. A corrente da caçamba é fabricada em aço temperado com alta resistência estrutural e ao desgaste. As caçambas são fabricadas em chapa estampada e as partes que ficam em contato com a argila são em chapa de aço resistente ao desgaste. As rodas motrizes internas da corrente porta-caçamba são dentadas mecanizadas com dentes, fixadas por meio de parafusos para sua substituição, formando uma engrenagem de 120° com três setores.
A movimentação do carro porta-barra é realizada por meio de dois moto-redutores com variador de frequência, previstos para trabalhar em duas velocidades principais, uma de trabalho e outra rápida. A elevação e graduação das diferentes posições da lança com suas correntes e caçambas, é obtida por meio de uma unidade hidráulica formada por dois pistões, um central e codificadores de posicionamento. Estes são comandados por um gabinete PLC programado com todos os dispositivos relevantes para o controle e segurança de todos os movimentos da máquina.
