Hydraulic Power Tilt for Excavators — WEITAI WPT Series
The WEITAI WPT is a hydraulic power tilt designed for excavators from 1.8 to 27 tonnes. Using a helical rotary actuator core — not a traditional hydraulic cylinder — it delivers up to 180° tilt with higher holding torque, lower profile, and a dual-lock safety system. As a direct OEM manufacturer, WEITAI offers the WPT at competitive pricing without distributor markup, in 7 models covering mini excavators through large construction machines.

Applications — What You Can Do with a WPT Tilt Coupler
Slope Grading and Embankment Work
Tilt the bucket to match slope angle without repositioning the machine, enabling continuous grading on inclined terrain.
Angled Trench Excavation
Cut trenches at precise angles for drainage pipe installation, even on sloped ground where a standard bucket cannot follow the grade.
Pipe and Cable Laying in Confined Spaces
Position attachments precisely in tight work areas near existing structures or utilities, reducing the need for manual finishing.
Ditch Cleaning and Clearing
Tilt the bucket to push cleared material to one side efficiently, speeding up drainage maintenance and vegetation removal.
Fine Grading and Landscaping
Achieve precise surface finishing on uneven terrain without constantly moving the excavator into new positions.
Demolition in Tight Access Areas
Control attachment angle precisely for careful, controlled demolition work near sensitive structures.
Compatible Excavator Brands
The WPT Power Tilt is compatible with major excavator brands including Komatsu,Caterpillar, Hitachi, Volvo, Doosan, JCB, Bobcat, Case, and Kubota, among others. Custom configurations are available for specific carrier requirements — contact WEITAI to confirm compatibility with your machine model.
Frequently Asked Questions
Q: What is the difference between a power tilt and a tilt rotator?
A: A power tilt tilts the attachment up to 180° on a single axis. A tilt rotator adds continuous 360° rotation as well. For most slope work, trenching, and grading applications, a power tilt is sufficient and more cost-effective than a tilt rotator.
Q: What excavator weight class does each WPT model fit?
A: The WPT Series covers 1.8T to 27T excavators across 7 models. See the specification table above for the exact model matching your machine weight.
Q: Can WEITAI customize the WPT for my machine?
A: Yes. WEITAI offers OEM and ODM configurations, including custom pin sizes and mounting bracket dimensions for specific carrier requirements. Contact WEITAI with your machine details to confirm compatibility.
