The main semi-trailers supplied include 40 ft container side lifter, windmill blade trailers, detachable gooseneck trailers, low bed trailers, container flatbed trailers, fuel tanker & fuel tanker trailers, bulk cement tank trailers, and bulk cargo transportation semi-trailers, acid tankers, dump semi-trailers, container side loaders truck, modular trailers, windmill blade adapter trailer.  Jerry semi-trailers have successfully entered more than 50 countries.  Such as Tanzania, Mozambique,  Malawi,  Zimbabwe, Zambia, Algeria, Sudan, Mali, Ghana, Nigeria, Sierra Leone, Liberia, Guinea, Senegal, Argentina, Chile, etc.

JERRY VEHICLE overcomes many difficulties in the automation welding fields of special commercial vehicles, auto parts, steel structures, construction machinery, etc.

Production line Of Common Semi Trailer

1. Stage of cutting steel sheet material

According to the drawings of each part produced by the design department, each part is cut out with a CNC cutting machine, such as beam webs, reinforcement plates, standard small accessories and so on.

2. Submerged arc welding beams, beams fixed, frame, welding suspension

The second step is to fix the cut web and the upper and lower wing plates to weld points, and then weld the beam by submerged arc welding.

At this time, the low bed trailer of the main beam is basically formed, only the side beams are welded to form the frame structure. And the traction pin traction plate is welded to the position required in the contract, the welding process is required to be high, otherwise, the lowbed trailer will be skewed.

3. Automatic Base plate welding machine:

JERRY VEHICLE adopts Automatic Base plate welding machine.

It can automatically track to weld the edges of base plate. Just move weldlng torch to the first corner of base plate, and press 'Auto Button on' ,the machine will track and weld all seams automatically without any operator. The high welding seams will improve the service life of the heavy semi trailers when loading the cargo on the bottom floor.

Tank production line:

This production line adopts the most advanced international high-end double pulse TIG Flat Butt Welding Machine, Tank Rolling Machine, Automatic Tig Welding Machine Tanks machines, etc, which fully realizes auto welding for plates and baffles plates, forming tank body at only one time by tank rolling machine.

Tank laser welding robots keep high welding precision, intelligent acquisition of welding seams, and unmanned operation by tracking the seams.

Automatic welding machine for tank trailer production line

The Tank Rolling Machine is exclusively designed and developed by Shuipo Welding & Cutting Equipment Manufacture Co., Ltd based on years of tank manufacturing experience and equipment debugging skills, which break traditional tank producing patterns. It adopts the advanced PLC program input technology, and the microelectronics technology, and is shaped by one-time.

Large-sized Tank Rolling Machine

The plasma arc welding that can allow the seam to be welded by one side in shape by two sides is first used during production, which prevents leakage of the tank.In addition, it combines automation technology and information technology, and uses a digital control system to control the tank manufacturing machines in production such as CNC cutting machine, CNC edge milling machine, delivering and turning over machine, giant flat butt welding machine, CNC bending machine, giant hydraulic dished head configuring machine.

It is applicable for the production of different kinds of tank trucks,such as fuel tanker trailers, power tank trailers, chemical tankers, concrete cement trucks, liquid tank trucks, Bulk powder tanker trucks, asphalt trucks, and milk tankers.

Frosted and painted

The frosting is the previous step of spray painting. Some manufacturers without shot blasting workshops will blow and polish the welding slag with high pressure gas at this stage.

Spray paint is usually sprayed in a well-ventilated shed. If you want to spray beautifully, you must first look at the coating and the technology of the technicians, but JERRY 40-foot low bed trailer will spray very beautifully. Basically, you don’t have to worry about this. We will be very attentive!

The device is uses of PC-based CNC technology, PLC programmable control technology, and a servo drive system developed by our company through the spraying process large box of special vehicles, a large box of Special Purpose Vehicle CNC automatic spraying system, closed purification painting room the gun is automatically executed and stored in the device, pre-special vehicle large box shape and spray pattern, color, real-time programming CNC automatic spraying system.
