Product Overview

• Suspension / Mount: Top Running Double Girder Low Profile, indicating that it's mounted on the structure above, featuring a low-profile design for space-saving efficiency.
• Capacity: With a capacity of 3.30 tons, it's suitable for handling moderate loads in industrial settings.
• Reeving / Lift: It uses a 2-part line reeving system and can lift loads up to 41 feet and 7 inches.
• Hoist Lift Speed: Capable of lifting loads at a maximum speed of 26 feet per minute, ensuring efficient vertical movement.
• Hoist Motor: Powered by a 7.5 kW motor, providing sufficient lifting power for smooth and reliable operations.
• Hoist Control: Equipped with closed-loop vector Variable Frequency Drive (VFD) control for precise and responsive lifting operations.
• Trolley Speed: The trolley system can travel at a maximum speed of 80 feet per minute, facilitating efficient horizontal movement along the runway beams.
• Trolley Motor: It has two motors, each rated at 0.55 kW, ensuring smooth and reliable movement of the trolley system.
• Trolley Control: Utilizes sensorless vector VFD control for precise and efficient control over horizontal movements.
• Power Supply: Designed for electric operation, compatible with a standard power supply of 230VAC, 3-phase, 60Hz, with a tolerance of ±5%.
• CMAA Class / Atmosphere / Location Class: Classified as CMAA Class D, suitable for standard weather-resistant service, making it suitable for outdoor installations and capable of withstanding various weather conditions.
• Trolley Gauge: With a trolley gauge of 78 inches, it provides sufficient spacing between the runway beams for smooth trolley movement.
• Approximate Weight: Weighs approximately 2000.00 lbs, making it relatively lightweight and easy to install while maintaining structural integrity.
