Product Series Overview: Engineered for Horizontal Stability

• Optimized Horizontal Housing: The casing is reinforced with strategic ribbing to counteract gravity-induced sagging and lateral forces, ensuring perfect alignment between the worm and wheel over thousands of operating hours.
• Double-Enveloping Core: The signature hourglass-shaped worm creates a broad area of contact, eliminating the edge-loading issues common in horizontal setups and significantly extending service life.
• Inherent Self-Locking Safety: The high friction angle of the globoid mesh naturally resists reverse rotation. This eliminates the need for external braking systems in many crane and drill applications, simplifying design and enhancing reliability.
• Rugged IP68 Protection: Construction means dust and water. The WEA Series features multi-stage labyrinth seals combined with high-performance lip seals, achieving IP68 ratings that keep abrasive concrete dust, mud, and rain completely out of the gear chamber.
• High Shock Load Capacity: Designed with safety factors exceeding typical construction standards (ISO/DIN), the WEA absorbs the violent jolts of starting, stopping, and dynamic lifting without gear tooth fracture.

Key Features: Why the WEA Series is the Smart Choice for Builders

1. Fail-Safe Load Holding: In horizontal mounting scenarios, gravity and wind constantly challenge the drive’s stability. Our self-locking worm mechanism ensures the machine holds its position firmly, eliminating "creep" and enhancing operator confidence during delicate lifts or precise drilling.
2. Compact High-Torque Output: By maximizing torque per unit volume, the WEA Series allows engineers to reduce the footprint of the rotation assembly. This lowers the overall center of gravity and increases the machine’s payload capacity—a crucial factor for mobile cranes and compact excavators.
3. Smooth, Vibration-Free Operation: Despite high reduction ratios, the multi-tooth contact ensures silky smooth power transmission. This reduces stress on the machine’s chassis and boom, minimizes load swing, and improves positioning accuracy for tasks like pile driving or foundation drilling.
4. Durability in Harsh Environments: From the dusty quarries of Australia to the muddy construction sites of Northern Europe, the WEA Series is built to last. Its sealed design and corrosion-resistant coatings protect against abrasive particles and corrosive elements.
5. Low Maintenance & Long Life: The robust gear meshing and high-quality synthetic lubricants (pre-filled) significantly extend service intervals. Many WEA units are designed for "sealed-for-life" operation, reducing total cost of ownership (TCO) for rental fleets and owner-operators.

Applications: Powering the World’s Toughest Machines

• Mobile Truck Cranes: Provides the reliable, self-locking rotation needed for quick setup and precise load placement in urban and rough-terrain environments.
• Crawler Cranes: Handles the massive torque requirements of large crawler cranes used in heavy industrial construction and wind farm installation.
• Rotary Drilling Rigs: Essential for the main rotation table of drilling rigs, delivering the high torque and stability needed to penetrate hard rock and soil layers.
• Concrete Pump Trucks: Powers the smooth, continuous rotation of the boom system, allowing operators to place concrete with precision in complex structures.
• Off-Road Excavators & Graders: Delivers the rugged performance needed for earthmoving equipment operating on uneven ground with high vibration and debris.
• Pile Drivers: Offers the stability and shock absorption required for driving piles into the ground with repetitive, high-impact force.

Why Partner with Us for Construction Drive Solutions?

• Specialized Globoid Gear Expertise: Manufacturing double-enveloping worms requires specialized hobbing and grinding capabilities. Our facility is equipped with advanced 5-axis CNC machinery dedicated to this complex geometry, ensuring perfect meshing and optimal load distribution for every WEA unit.
• Proven Field Performance: Our drives are currently operating in some of the harshest construction environments globally, proving their resilience against extreme cold, heat, dust, and mud.
• Custom Engineering Support: Every machine model has unique constraints. We work directly with your engineering team to customize input shafts (hydraulic motor mounts), gear ratios, and sealing solutions to fit your specific chassis and hydraulic system.
• Strict Quality Assurance & Traceability: Every WEA unit undergoes rigorous load testing, including dynamic shock simulations and endurance runs. We provide full material certification (MTRs) and traceability for all critical components, meeting ISO, CE, and DIN standards.
• Cost-Effective Robustness: We deliver European-level quality and durability at a competitive price point, helping you reduce capital expenditure (CAPEX) without compromising on safety, longevity, or performance.
