Concrete pump truck

Concrete pump trucks are high-end specialized equipment in the field of construction machinery. The overall structure of these vehicles consists of components such as the chassis sub-frames, the rotating base, the leg assemblies, the boom system, and the cylinder supports, all of which are made of high-strength and heavy-duty structural parts.

Flexibility

Staff will make a production analysis of the customer’s future production needs and goals. Material flow analysis and planning define the optimal configuration and layout for your site.
Rhythmicization

Remote repair service enables instant visual connection to the machine despite its geographical location.
Intelligentization

Full range of spare and wear parts, including original spare parts, retrofit parts, and approved replacement OEM parts, all meeting the strictest quality criteria.

Concrete pump trucks are high-end specialized equipment in the field of construction machinery. The overall structure of these vehicles consists of the chassis sub-frames, the rotating base, the leg assemblies, the boom system, the cylinder support, etc., all of which are made of high-strength and heavy-duty structural components. The workpieces are generally made of high-strength steel thick plates, featuring large plate thickness, long weld seams, complex stress conditions, high fatigue resistance requirements, and difficult control of welding deformation.

Overview of the Automated Welding Workstation for Pump Truck Legs

The outriggers of the concrete pump truck are the core heavy-load structural components that bear the entire weight of the vehicle and provide safety protection. They are divided into front outriggers, rear outriggers and telescopic outriggers, and are constructed with thick plates of high-strength alloy steel in a box-type structure.

The entire production line adopts a multi-station assembly line layout, with segmented processes and coordinated operations.

The production line adopts a streamlined layout. The equipment has a high degree of integration and strong automation. The core equipment consists of the following:

•The overall precision processing base platform is adopted, along with multi-point synchronous hydraulic pressing, end positioning and side wall clamping structures.

• Adjust all the external straight welds, internal fillet welds and transition welds of the outriggers to the optimal position for flat welding and ship-shaped welding.

• The entire welding process parameters are digitally collected throughout the line, monitored in real time, and can be stored and traced.

•The production line is compatible with a full range of pump truck leg products including fixed, telescopic, and various-length models.

Overview of the Automated Welding Workstation for Left and Right Front Legs

The left and right front outriggers of the concrete pump truck are the core load-bearing and safety support components of the vehicle during operation. They are a pair of symmetrical high-strength steel box-type thick plate structures, mainly responsible for bearing the overturning load of the entire machine, the vehicle's own weight, and the construction impact load.

1. Integrated Assembly and Welding Fixture

An integrated symmetrical positioning fixture for the left and right outriggers, which adopts an overall precision-machined rigid reference, is designed with dedicated limit and clamping mechanisms based on the mirror-image structural characteristics of the left and right outriggers.
2. Improve production efficiency

The production line can achieve simultaneous production of two pieces, significantly increasing the production cycle, reducing manual intervention by over 60%, and lowering labor costs and rework expenses.
3. Flexible Design

It can automatically detect the errors of the workpiece group alignment, real-time correct the welding trajectory, and precisely control the penetration depth, weld width and weld formation.
4. Lean Control of Welding Cycle Time

Process standardization, production intelligence, quality controllability, and capacity scalability are the core complete sets of equipment for rotary drilling rigs.

Overview of the Automated Welding Workstation for Rearly Adjustable Legs

It is composed of a fixed outer cylinder and an extendable inner cylinder, and belongs to a high-precision, high-stiffness, and slidable heavy-load box structure.

Core advantages of the process

It is specially customized for the structural characteristics of the telescopic outriggers of pump trucks, enabling fully automatic, low-deformation and high-precision welding production of all weld seams of the inner and outer cylinders of the telescopic outriggers.
Robotic Welding Station

The workstation is equipped with a customized rigid fixture system for telescopic legs. It uses an overall precision machined reference platform and is designed with multiple positioning points to address the deformation tendency of long boxes.
Improve production efficiency

Long weld seams, corner weld seams and lap weld seams are all adjusted to the optimal ship shape weld configuration.
Flexible Platform Design

Effectively address the technical challenges of "difficult alignment, hard welding straightness, and difficult coordination" for telescopic outriggers
