Alborz province and Karaj city, as the connecting highway between the capital and the western and northern provinces of the country, plays a vital role in the transit of goods and heavy machinery. The daily traffic of thousands of heavy vehicles from this axis has created an urgent need for technical support services, trailer construction and specialized repairs. Among the types of trailers, back breakers have a special place due to the transportation of super heavy traffic loads and containers as the global standard for transporting goods. Production and repair of all types of back breakers and containers in Karaj is one of the most challenging areas of the commercial vehicle industry, which requires advanced engineering knowledge, heavy equipment and high practical experience. Jahan Sanat production complex, with many years of brilliant history in this region, is known as the main hub of heavy transport fleet design, construction and reconstruction, and provides distinctive services to drivers and transport companies.

Why Karaj is the hub of the trailer industry.

The existence of easy access to the iron and steel market, as well as the presence of elite specialists in this area, has made Karaj the specialized hub of this industry. By taking advantage of this locational potential and combining it with current knowledge, Jahan Sanat Production has launched an equipped production and repair line that meets the needs of the entire country. The production and repair services of all types of back breakers and containers in Karaj in this complex are equal to international standards and make the imagination of product owners and drivers comfortable in terms of safety and quality.

backbreaking; Road transport giant

Lowboy Trailers are trailers with low loading height designed to carry heavy and bulky loads. The construction of these trailers is much more complicated than the usual soles. The chassis of an excavator must be able to withstand extreme point loads (such as the weight of a bulldozer chain) without bending or breaking. In the process of manufacturing and repairing all types of back breakers and containers in Karaj by Jahan Sanad, we use alloy steels with very high tensile strength (such as ST52 and anti-wear steels).

"Gooseneck" design in back breakers is one of the most sensitive parts of engineering. This part must properly transfer the load pressure to the die plate. In the world of industry, we design all kinds of two-axle, three-axle, four-axle and even multi-axle bogies according to the customer's needs. Our expertise in the production and repair of all types of back breakers and containers in Karaj includes the construction of bridge, sliding and side-mounted back breakers, which have high flexibility in carrying different loads.

Engineering of container construction and metal rooms

Containers are the standard boxes on which world trade revolves. But building a high-quality container that is resistant to sea moisture, port crane strikes and road jolts is not the work of every workshop. In the production and repair department of all types of back breakers and containers in Karaj, we produce standard 20-foot and 40-foot containers, as well as special containers (such as open top or open side).

The use of corrugated steel sheets with appropriate thickness, reinforced columns in the four corners, and safe locking and hinge systems are among the distinctive features of containers in the world of industry. We also make tented rooms and metal roofs for trucks and trailers. In the production and repair project of all types of back breakers and containers in Karaj, complete sealing of the roof and body to prevent rain penetration is our first priority to ensure the safety of the cargo.

Back-breaking specialized repairs; Restoration of power

Back breakers are under severe stress due to the nature of their work. Chassis breakage, cracked welds in the neck area, failure of hydraulic ramps and depreciation of the suspension system are some of the common problems of these trailers. Back breaker repair requires heavy equipment such as powerful hydraulic jacks and penetration welding machines. Jahan Sanat production, as a specialized center for the production and repair of all types of back breakers and containers in Karaj, carries out the complete reconstruction process of back breakers.

We first find the exact location of hairline cracks in the chassis with non-destructive testing (NDT). Then, with standard engineering methods (such as creating a V-shaped groove and multi-pass welding), we repair the damaged area and reinforce it with fishplates. Our repairs in the field of production and repair of back breakers and containers in Karaj are such that the restored trailer regains its nominal load carrying capacity and its safety is guaranteed.

Reconstruction and change of use of container

After some time of use, the containers may suffer from rotting of the bottom, crookedness of the body, or damage to the doors. Also, many customers want to convert used containers into office, residential or warehouse canopies (change of use). In Jahan Sanat production, the production and repair services of all types of back breakers and containers in Karaj include smoothing the container body, replacing the floor boards with waterproof plywood and repairing the lock mechanism.

In terms of conversion, we turn containers into functional spaces with precise cutting and professional insulation. Installation of doors and windows, electrical wiring and thermal insulation are part of our services. This ability to rebuild is an important part of the production and repair service cycle of all types of back breakers and containers in Karaj, which reduces the cost of buying new containers for customers.

Substructure system and axles in the back breaker

One of the most vital parts in the production and repair of all types of back breakers and containers in Karaj is the correct selection and installation of axles. Due to their low height, back breakers usually use small size tires but with high weight bearing. The axles of these trailers must be able to withstand concentrated loads. We use the best brands in the world of industry (Turkish, German and first class Chinese).

Back-breaking suspension system can be spring or pneumatic (air). In newer models, the hydraulic suspension system is also used to adjust the height. Repairing and adjusting these systems requires high technical knowledge. Axis alignment has a direct effect on tire life and fuel consumption. Our technical team balances the axles and adjusts the brake system for quick response on downhills using precise tools in the production and repair of all types of back breakers and containers in Karaj.

The importance of loading ramps in backbreaking

Loading of heavy machinery on the back breaker is done through rear ramps. These ramps should be strong enough to support the weight of a 30-ton loader when going up. In Jahan Sanat production, we make ramps with double design and internal grid. In the production and repair services of all types of back breakers and containers in Karaj, we have also provided the possibility of installing hydraulic ramps.

Hydraulic ramps can be easily opened and closed using an electric or manual Power Pack, eliminating the risk of injury to the driver when moving heavy manual ramps. Repairing hydraulic ramp jacks, replacing hoses and removing oil leakage are part of our daily services in the production and repair center of all types of back breakers and containers in Karaj.

flooring and covering; Wood or metal?

The back-breaking floor and the container must have the necessary friction to prevent the load from slipping. Back breakers are usually made of saturated wood or corrugated steel sheets. Wood has the advantage of creating more friction and being nailed to hold the load, while metal is more durable. In the project of production and repair of all types of back breakers and containers in Karaj, we perform floor construction according to the customer's needs.

Replacing the broken and rotten wood of the back-breaking floor is one of the common requests in repairs. We use high quality and dried wood to withstand the weather changes. In the production and repair department of back breakers and containers in Karaj, we also use Marine Grade Plywood for containers, which are completely resistant to moisture.

specialized welding; The beating heart of production

The quality of a back breaker or container directly depends on the quality of its welding. A poor weld on a back-breaking chassis can lead to major disaster down the road. In the production of Jahan Sanat, all welders have valid certificates and use advanced CO2 and sub-powder welding machines. In the process of manufacturing and repairing all types of back breakers and containers in Karaj, we choose the type of electrode and welding wire according to the metal alloy.

Stress relief after welding is another important step that prevents subsequent cracking. Following the principles of WPS (Welding Instructions), we create an integrated and resistant structure. This obsessive precision in welding has turned Jahan Sanat into a reliable brand in the field of manufacturing and repairing all types of back breakers and containers in Karaj.

Painting and corrosion protection

Back breakers and containers are constantly exposed to harsh weather conditions, road salt and moisture. If they don't have a proper color coating, they will rust quickly. In the workshop for the production and repair of all types of back breakers and containers in Karaj, we first clean and roughen the surfaces completely with sandblast so that the color has the necessary adhesion.

Then we use zinc-rich epoxy primers and industrial polyurethane paints. In addition to beauty, these colors create a protective and hard layer on the metal that is resistant to scratches and chemicals. Production and repair services of all types of back breakers and containers in Karaj, in our collection, include color restoration and complete painting of used trailers to give them a new and beautiful appearance.

Technical advice and custom design

Not all loads are standard. Sometimes, to carry a special turbine or a strange drilling machine, a backbreaker with special dimensions and specifications is needed. The production engineering unit of Jahan Sanat is ready to provide the best plan by carefully examining the load map and the movement path. Our expertise in manufacturing and repairing all types of back breakers and containers in Karaj allows us to design and produce wide load trailers, variable height trailers and telescopic chassis.

Our consultation is not only limited to construction; But also in the field of repairs, we help customers to decide whether it is profitable to rebuild an old trailer or buy a new one. This honesty in consulting is the main pillar of our activity in the field of production and repair of all types of back breakers and containers in Karaj.

Supply of parts and spare parts
