Heavy-Duty Hydraulic Welding Positioner Designed with Fork Pockets for Fast, Simple Workpiece Loading

The machine adopts a heavy-duty welded steel base with an integral reinforced structure. Thickened gusset plates are welded inside the base to strengthen overall rigidity and prevent structural deformation under heavy load.

Four standard forklift pockets are integrally formed at the bottom of the base. All lifting stress points are locally thickened and reinforced to ensure no bending, cracking, or permanent deformation during frequent forklift transportation and full-load movement.

This unique mobile design completely breaks the fixed-installation limitation of traditional positioners. The equipment can be freely moved between different working areas, realizing flexible workshop layout, rapid task switching, and maximized equipment utilization.

The main frame, tilting support, and bearing beam are all fabricated with thick industrial steel plates through full-penetration welding. After welding, the entire frame undergoes high-temperature stress-relief annealing treatment to eliminate internal welding stress, avoiding long-term structural deformation and mechanical fatigue.

Key assembly planes and table mounting surfaces are precisely processed by CNC machine tools to guarantee ultra-high flatness, verticality, and structural stability. The whole machine runs smoothly without shaking, vibrating, or deflecting under long-term full-load operation.

This positioner adopts an industrial-grade integrated hydraulic system, including a silent hydraulic power unit, a high-pressure wear-resistant hydraulic cylinder, and an imported hydraulic control valve group.

It realizes smooth stepless hydraulic tilting within 0°–90°. The hydraulic system has built-in buffer start and buffer stop functions, ensuring soft and shock-free tilting movement that protects workpieces and fixtures from impact damage.

Equipped with a hydraulic self-locking holding valve, the platform can be locked firmly at any angle without drifting, slipping, or position offset — even under continuous vibration and full-load working conditions. All hydraulic components are protected by anti-spatter and dust covers to adapt to harsh welding environments.

The rotary table is equipped with a large-diameter heavy-duty slewing bearing, featuring ultra-strong load capacity, high rotation accuracy, and excellent anti-overturning performance.

Driven by a high-precision worm gear reducer and frequency conversion motor, the rotation speed ranges from 0.1 rpm to 1.0 rpm with infinitely variable speed regulation. Rotation is uniform, stable, and free of jitter, stagnation, and speed fluctuation.

It perfectly matches MIG, MAG, TIG, and SAW automatic welding processes, ensuring consistent circumferential welding speed, uniform heat input, stable weld penetration, and a smooth, beautiful weld bead appearance.

The rotary working table is reserved with standard T-slots for flexible installation of customized fixtures, tooling plates, and positioning molds.

The standard four-jaw self-centering chuck supports dual clamping modes: external clamping and internal expansion clamping. It can quickly and accurately fix various pipes, flanges, ring parts, and cylindrical workpieces with high concentricity and firm clamping force. No eccentric shaking or workpiece loosening occurs during high-speed rotation, ensuring stable and repeatable processing quality.

The equipment is equipped with dual control modes: a handheld remote control and a local fixed control box. Operators can remotely control rotation start/stop, speed adjustment, and hydraulic tilting angle adjustment at a safe distance, effectively avoiding high-temperature radiation and welding spatter hazards.

Built-in multiple industrial safety protection functions include hydraulic overpressure protection, motor overload protection, tilting limit protection, and emergency stop self-locking protection. Once abnormal operation or overload occurs, the equipment automatically powers off and stops to ensure personnel and equipment safety.

All transmission mechanisms, electrical components, and hydraulic pipelines adopt a fully enclosed protective design that effectively blocks welding spatter, metal dust, oil stains, and grinding debris.

The whole machine is treated with pickling rust removal, anti-rust primer, and industrial finish paint, featuring strong corrosion resistance, wear resistance, and oxidation resistance — suitable for long-term 24-hour continuous industrial production.

Built-in forklift pockets allow free equipment movement without overhead cranes, slings, or auxiliary tools, greatly improving workshop flexibility and reducing handling costs.

Hydraulic drive ensures an ultra-smooth tilting process. The self-locking system guarantees stable angle fixation without slipping, providing extremely safe working conditions.

0°–90° arbitrary angle conversion turns overhead welding and vertical welding into flat welding, greatly reducing porosity, undercut, slag inclusion, and welding rework.

Frequency conversion stepless speed regulation ensures uniform workpiece rotation, stable weld heat input, and consistent batch welding quality.

Intelligent remote control design reduces operation difficulty. Ordinary workers can complete professional positioning work, lowering reliance on experienced welders.

Stress-relieved rigid frame and high-quality hydraulic components ensure long service life, low failure rate, and easy daily maintenance.

Compatible with all kinds of automatic welding equipment, suitable for welding, grinding, polishing, assembly, and inspection of various circular workpieces.
