Heavy Duty Hydraulic Welding Positioner with Smooth Hydraulic Tilt, Stop at Any Desired Working Angle

The entire base, support frame and tilting beam are fabricated with thick industrial steel plates and sectional steel through full-penetration welding. After welding, the whole structure undergoes high-temperature annealing stress-relief treatment to eliminate internal welding stress.

This manufacturing process ensures the frame maintains ultra-high rigidity and stability during long-term full-load operation, frequent angle switching and torque force application. All key mounting surfaces are CNC precision machined to guarantee flatness, verticality and assembly accuracy, effectively avoiding workpiece shaking and processing deviation.

Equipped with an industrial silent hydraulic power pack, high-pressure wear-resistant hydraulic cylinder and imported hydraulic balance valve group, the machine achieves smooth stepless hydraulic tilting within 0°–90°.

The unique buffer start and buffer stop design eliminates impact, vibration and noise during tilting. Workpieces and fixtures will not be displaced or scratched during angle adjustment. With built-in hydraulic self-locking function, the table can be locked at any arbitrary angle permanently — no sinking, drifting or angle deviation occurs under full-load gravity, grinding pressure or bolt-tightening torque force.

All hydraulic pipelines and core components are equipped with dust-proof, anti-spatter and anti-corrosion protective covers to adapt to harsh workshop environments.

The rotary table adopts a large-diameter heavy-duty slewing bearing, featuring strong load-bearing capacity, excellent anti-overturning performance and stable rotation accuracy.

Driven by a frequency conversion motor and high-precision worm gear reducer, the rotation speed ranges from 0.1 rpm to 1.0 rpm with infinitely variable speed regulation. Rotation runs evenly and smoothly without stagnation or speed fluctuation.

Low-speed micro rotation is ideal for precision grinding, fine deburring, uniform bolt assembly and 360° visual inspection. Constant stable speed perfectly matches automatic welding processes such as MIG, MAG, TIG and SAW, ensuring uniform weld heat input, consistent penetration depth and smooth weld bead surface.

The rotary table is reserved with standard T-slots for flexible installation of custom fixtures, positioning molds and auxiliary tooling. The standard four-jaw self-centering chuck supports dual clamping modes: external clamping and internal expansion clamping.

It can quickly and accurately fix various tubular, circular and ring workpieces with high concentricity and firm clamping force. No loosening or eccentric shaking occurs during rotation and large-angle tilting, ensuring stable processing quality for batch production.

This positioner is equipped with a handheld remote control and a local fixed control box for dual operation modes. Operators can remotely control rotation start/stop, speed adjustment and hydraulic tilting at a safe distance to avoid high temperature, welding spatter and mechanical injury risks.

Multiple industrial safety protections are integrated, including hydraulic overpressure protection, motor overload protection, tilting limit protection and emergency stop shutdown. The equipment automatically stops under abnormal conditions to ensure personnel and equipment safety.

All transmission parts, electrical components and hydraulic interfaces adopt a fully enclosed protective design to isolate metal dust, grinding debris, oil stains and welding spatter. The whole machine is treated with pickling rust removal, anti-rust primer and industrial finish paint, offering excellent wear resistance, corrosion resistance and oxidation resistance for long-term continuous industrial operation.
