Transfer Arm™
Positech's low-profile Transfer Arm allows placement in areas too confined
to accommodate larger material handling equipment. Specifically designed
for minimum vertical travel and to fit limited-access work cells, this machine
is well-suited for loading and unloading machining centers and for positioning
assembly. Mounting options include pedestal, portable base, overhead
fixed or on trolleys.
For Performance and Quality
- Fits into work cells too small for larger material handling equipment
- Hydraulic and pneumatic models
- Push-button metering valve or balance controls lift/lower for ease of operation.
- Hardened lift-section components for extended service life
- Standard reach and vertical travel can be modified to fit requirements
- Drag brakes on 3 axes for personalized adjustment
- End of arm rotating axis has: up to 12,000 inch pounds of end of arm moment loading
- Mounting options include pedestal, portable base and overhead fixed or on trolleys
- Power/control unit remote mount for operation in explosive or clean room environments
- Pneumatic is designed to be operated with clean and dry air
- Precision bearings and thrust washers at joint for smooth motion and long life
Safety Features
- 5:1 design factor minimum on all structural components
- Pilot operated lock valve on lift cylinder and gripper cylinders prevents vertical arm movement and loss of payload if supply pressure is interrupted
- Gripper Safety Circuitry senses the pressure in the cylinder and does not allow the part to be released from tooling unless it is supported
