The engineering team that developed the first hail cannon in Serbia.
Mechanical and electrical engineers in one yard in Ljig — in collaboration with a partner from Čačak, we design, manufacture and service PGT-A80 hail cannons and mobile solar stations.
We design. We manufacture. We service.
All in one yard.
TRAILING DOO designs, develops, manufactures and distributes advanced systems for hail protection (the hail cannon), mobile solar power stations, agricultural and forestry trailers, metal structures, and equipment used in field farming, vegetable growing, fruit growing and viticulture.
The driving force behind the company is a team of experienced mechanical and electrical engineers. That's why we design and develop our products entirely in-house — from the mechanical structure and control cabinet to the mobile app and radar integration. They carry the knowledge, ideas and effort that guarantee flawless, consistent quality.
It means that when something needs repair or an upgrade, we don't wait on a supplier on the other side of the world. The engineer who drew the part comes to your field.
From the first device to a network of cannons across Serbia.
The first device. The first yard.
A team of mechanical and electrical engineers in Ljig builds and commissions the first hail cannon of this type in Serbia. The device works on the principle of combusting an acetylene-air mixture — producing an ionizing acoustic shock wave aimed at the cumulonimbus cloud.

Season after season — the device grows with the orchards.
Dozens of seasons in orchards, vineyards and greenhouses across Serbia. After every season — a structural revision, a control-cabinet upgrade, a new module for remote control. A mobile app for iOS and Android, GSM/GPRS and later LTE 4G communication, push notifications and radar integration. During this period we also expanded production to agricultural and forestry trailers.
PGT-A80 — 80 ha per device, over 90% efficiency.
The current PGT-A80 model covers up to 80 hectares per device (a circle of 500 m radius), with efficiency over 90% and an annual running cost of at most ~€800 and mobile solar power stations. We have been building special agricultural trailers for years, and this year we are also adding mobile solar stations from 5—10 kW to our offering. The devices are in operation in orchards, vineyards and greenhouses across central Serbia.
A wider field of application. The same team.
Extending hail-protection systems into new sectors and developing a new generation of the communication module and power supply from our own solar panels. No matter how much we grow — the headquarters stays in Ljig, and the service, spare parts and support in Serbian, from our own yard.
Experienced engineers.
Honesty as the first tool.
The TRAILING DOO team is made up of experienced specialists gathered around a few simple working principles: honesty in conversation with the client, keeping our word, and genuine attention to needs in the field. Long before any catalogue or website, those three things earned us a reputation as a reliable partner in every market we serve.
When you call +381 63 384 010, you don't reach a call center — someone answers who can speak to the coverage radius, acetylene consumption, or push notifications in the app. Our goal is a long-term relationship, not a one-time sale.
Three things we never change.
Engineers in one team
Mechanical and electrical disciplines work side by side — from the mechanical structure and control cabinet to the mobile app. We develop and manufacture it all ourselves.
A reliable partner since 2015
Devices in operation season after season. Keeping our word and caring about our clients' needs earned us a reputation as a reliable partner — and long-term relationships instead of one-time sales.
Developed and manufactured in Serbia
Everything is made in Ljig and Čačak. Service, spare parts and technical support — in Serbian, from our own yard. No waiting on a foreign supplier.
Let's talk
about your protection.
We come to your field, take measurements and calculate the protection zone — with no obligation. An engineer from our team answers, not a call center.
