Product Introduction & System Selection

Workbench + Grid Pattern + Table Type + Support System + Core Accessories = Your Complete Solution

STEP 1: Select Bore Size (Defines Load Capacity)

ExampleSystem SpecWorkpiece Features & LoadTypical Applications
Heavy Duty (Φ28)
Heavy Duty (Φ28) Thick plate welding, high thermal stress, large-tonnage or extra-long structural parts Excavator booms, truck chassis frames, rail vehicle underframes, large steel structures
General Purpose (Φ22)
General Purpose (Φ22) Covers medium-small parts, suitable for ~80% of welding scenarios Auto parts, medium machinery components, complex frame assemblies, pipe & valve combinations
Light Duty (Φ16)
Light Duty (Φ16) Sheet metal, small lightweight parts requiring high precision Electronics enclosures, thin-wall sheet metal, precision instrument housings, lightweight tubes, robotic welding prototyping

STEP 2: Select Grid Pattern (Defines Positioning Density)

Φ28 / Φ22 Options
  • Standard grid (100×100mm): Most common layout, suitable for the majority of standard workpieces
  • Optimized grid (100×100mm): Diagonal grid, 1.5x increased positioning area
  • Fine grid (50×50mm): 4x positioning area, designed for complex or small parts requiring precise adjustment
Φ16 Options
  • Standard grid (50×50mm): High-density layout for small-part assembly boundaries
  • Optimized grid (50×50mm): Further increased positioning area for dense fixturing of fine workpieces

STEP 3: Select Table Type & Material (Defines Service Life)

Table TypeMaterialSurface HardnessDescription
Basic Carbon Steel Q355 Basic non-hardened table for intermittent welding with limited budget.
Dimensioned Carbon Steel Q355 Precision mm-scale markings on all four sides for quick visual alignment.
Hardened Carbon Steel Q355 HRC 35 Advanced surface hardening for significantly improved wear and impact resistance.
Dimensioned & Hardened Carbon Steel Q355 HRC 35 Combines HRC 35 hardening with four-side mm-scale markings for durability and efficiency.
Super-Hardened High-Performance Alloy Steel HRC 60 Upgraded base material. Extreme hardening with precision mm-scale markings. Maximum deformation resistance, anti-spatter, ideal for severe duty cycles.
Stainless Steel 304 Stainless Steel Special material with four-side mm-scale markings. Designed for aluminum and stainless steel workpieces where iron contamination must be avoided.

STEP 4: Select Support System (Defines Working Height)

  • Standard / Anchor legs: Static capacity > 5 tons per leg, ±30mm height adjustment. Ideal for permanent stations.
  • Telescopic legs: Height adjustable (e.g. 550-900mm), capacity > 3 tons. Adapts to large assembly heights.
  • Swivel castor legs with brake: Max static load 500kg per leg. High mobility for flexible workshop layout.
  • Stepless adjustable lift leg (NEW): 300kg capacity per unit, stepless adjustment (350-485mm), interchangeable top flange, castor or foot.
  • Heavy-duty hydraulic lift stations: Capacity from 2 to 4.5 tons. Industrial hydraulic pump and electric control for stable platform lifting.
