Need help?Do you have a question about the Helac POWERTILT PT Series and is the answer not in the manual?
The document describes the Helac PowerTilt, a swing attachment designed for excavators and other carriers, enabling them to tilt buckets and other attachments up to 180 degrees. This functionality significantly enhances the versatility and productivity of the carrier by allowing precise positioning of attachments without frequently repositioning the entire machine.
The PowerTilt is a hydraulic swing attachment that mounts between the carrier's stick and the attachment (e.g., a bucket). It utilizes a Helac's oscillating spline piston design, which converts linear piston motion into powerful shaft rotation. The PowerTilt is composed of a housing and two moving parts: the central shaft and the annular piston. The helical spline teeth machined on the shaft engage matching splines on the inside diameter of the piston. The outside diameter of the piston carries a second set of splines, of opposite hand, which engage with matching splines in the housing's internal ring gear. As hydraulic pressure powers the piston back and forth within the housing, the splines cause the shaft to rotate. This design allows for a 180-degree rotation, providing exceptional flexibility for various tasks.
The PowerTilt is available in several configurations:
These configurations allow for adaptation to various carriers and attachments, including custom backhoe and excavator models.
The manual provides detailed specifications for various PowerTilt models (05 through 12), covering aspects such as rotation, weight, output torque, holding torque, and maximum straddle moment.
Rotation: All models (05-12) offer a 180-degree rotation.
Approximate PowerTilt Weight (LB / KG):
Output Torque (IN-LB @ 3000 PSI / N.m @ 210 bar):
Holding Torque (IN-LB @ 3000 PSI / N.m @ 210 bar):
Maximum Straddle Moment Loads (IN-LB / N.m in thousands):
Maximum Recommended Bucket Widths:
Torque Specifications: The manual provides detailed torque specifications for various fasteners, including relief valve, port plug, shaft plug, and different bolt sizes (M10 to M30). For example, M10 x 1.5 bolts require 44 ft/lb (60 N.m), while M30 x 3.5 bolts require 1230 ft/lb (1670 N.m).
End Cap Torque Specifications: End cap torque specifications are provided for models 06 through 12, ranging from 350-500 ft/lb (475-680 N.m) for model 06 to 2580-3100 ft/lb (3500-4200 N.m) for model 12.
Hydraulic Pressure: The hydraulic circuit requires 3000 PSI (210 bar) for optimal operation. The maximum recommended operating pressure is 3200-3500 PSI (220-240 bar), with a maximum circuit pressure range of 6000 PSI (400 bar).
Enhanced Versatility: The PowerTilt allows operators to tilt attachments up to 180 degrees, enabling tasks such as grading, ditch cleaning, demolition, and material handling to be performed with greater precision and efficiency. This reduces the need for frequent machine repositioning, saving time and fuel.
Easy Installation: The manual outlines a step-by-step process for installing the PowerTilt onto the carrier and mounting a bucket onto the PowerTilt. This includes checking dimensions, installing link pins, and connecting hydraulic hoses.
Bucket Removal: Instructions are provided for safely removing a bucket from the PowerTilt, emphasizing the importance of supporting the bucket and releasing hydraulic pressure.
Hydraulic Requirements: The PowerTilt requires a two-way hydraulic circuit capable of providing 3000 PSI (210 bar). The circuit includes a directional control valve and an integral relief valve set to open between 3000 and 3200 PSI (210 and 220 bar).
Hose Routings: Suggested hose routings are provided to ensure proper connection and prevent damage to the hoses during operation.
Safety Precautions: The manual emphasizes several safety measures, including:
Regular Greasing: The PowerTilt requires regular greasing of pivot points and other moving parts to ensure smooth operation and extend component life. The manual recommends using NLGI #2 lithium-based grease.
Hydraulic Fluid Maintenance: Hydraulic fluid should be flushed weekly from the PowerTilt. The fluid level should be checked daily, and the fluid should be clean and free of contaminants. The manual recommends using ISO VG-46 hydraulic fluid.
Thrust Washers Inspection: Thrust washers should be inspected regularly for wear and replaced if necessary to prevent excessive shaft endplay.
Seal and Bearing Maintenance: The manual provides detailed instructions for disassembling and reassembling the PowerTilt, including procedures for replacing seals, bearings, and piston parts. It is recommended that these tasks be performed by qualified personnel.
Troubleshooting Guide: A comprehensive troubleshooting guide helps identify and resolve common issues such as:
Parts List: A detailed parts list with item numbers, descriptions, and quantities is provided to facilitate ordering replacement parts.
Warranty Information: Helac Corporation provides a warranty for its products, covering defects in material and workmanship for a period of one (1) year or 1000 service hours, whichever occurs first. The warranty is voided if the product has been modified or repaired by unauthorized personnel.
The PowerTilt is designed for durability, with all working components made from steel housing and tough exclusion seals to keep out dirt, water, and other contaminants. Regular maintenance and adherence to the specified procedures are crucial for ensuring the longevity and optimal performance of the PowerTilt attachment.
