Product Overview
Suspension / Mount: The crane is designed with a top-running double girder suspension/mount for both the main and auxiliary components, providing robust support and stability for heavy lifting tasks.
Capacity: With a main hoist capacity of 20.00 tons and an auxiliary hoist capacity of 11.00 tons, this crane offers ample lifting power to handle a wide range of loads, ensuring versatility and efficiency in various industrial applications.
Reeving / Lift: Featuring 5 part line reeving for the main hoist, enabling a lift of 22'4", and 4 part line reeving for the auxiliary hoist, allowing a lift of 29'1", this crane offers flexibility in lifting heights to accommodate different load requirements.
Hoist Lift Speed: The crane's main hoist operates at a maximum lift speed of 12.00 feet per minute (FPM), while the auxiliary hoist offers a maximum lift speed of 13.00 FPM, ensuring efficient and precise vertical movement of loads.
Hoist Motor: Powered by a 13.4 KW motor for the main hoist and a 7.5 KW motor for the auxiliary hoist, this crane delivers reliable and powerful lifting performance, capable of handling heavy loads with ease.
Hoist Control: Equipped with closed-loop vector Variable Frequency Drive (VFD) control, the crane ensures precise and smooth hoisting operations, enhancing safety and productivity in material handling tasks.
Trolley Speed: The crane features a maximum trolley speed of 80.00 FPM, facilitating swift and efficient horizontal movement of loads across the workspace, increasing overall productivity and workflow efficiency.
Trolley Motor: Utilizing two motors, each rated at 0.75 KW, the crane's trolley system ensures consistent and reliable movement along the runway beams, contributing to smooth and precise load positioning.
Trolley Control: With sensorless vector Variable Frequency Drive (VFD) control, the crane provides accurate and responsive trolley maneuvering, allowing operators to maintain precise control over load movement, enhancing operational efficiency and safety.
Power Supply: Designed for electric power operation, the crane operates at 460VAC, 3-phase, 60Hz, with a tolerance of ±5%, ensuring compatibility with standard power supplies and reliable performance in various industrial environments.
CMAA Class / Atmosphere / Location Class: Classified as CMAA Class D for standard indoor service, the crane is suitable for use in a wide range of indoor industrial environments, providing reliable and efficient material handling solutions.
Trolley Gauge: With a trolley gauge measuring 72.0000 inches, the crane offers ample spacing between the runway beams, allowing for smooth and reliable trolley movement, ensuring optimal performance and safety during operation.
Approximate Weight: Weighing approximately 4600.00 lbs, the crane strikes a balance between robustness and maneuverability, ensuring structural integrity while maintaining ease of installation and operation.
