Product Overview

Type: The DB40U29-12 is an under-running double girder crane designed for heavy-duty industrial applications, engineered to provide reliable and efficient material handling solutions in indoor settings.

Capacity: With a robust capacity of 20.00 tons, this crane is built to handle heavy loads with ease, making it ideal for demanding industrial environments where substantial lifting capabilities are required.

Reeving | Lift: Featuring a 5-part reeving system, the DB40U29-12 offers a generous lifting height of 29 feet and 5 inches, providing versatility for a wide range of lifting tasks, from light to heavy loads.

Hoist Lift Speed: Operating at a maximum speed of 12.00 feet per minute, the hoist lift system ensures controlled and precise vertical movement of loads, enhancing operational efficiency and safety.

Hoist Motor: Powered by a robust 13.4 kW motor, the hoist mechanism delivers reliable and consistent performance, providing ample power for lifting heavy loads while maintaining smooth operation.

Hoist Control: Equipped with a closed-loop vector Variable Frequency Drive (VFD) control system, the hoist offers precise speed control and torque management, ensuring optimal performance and safety during lifting operations.

Trolley Speed: With a maximum trolley speed of 80.00 feet per minute, the trolley system enables swift and efficient movement of loads along the crane span, facilitating quick material handling tasks.

Trolley Motor: The trolley is driven by four motors, each rated at 0.3 kW, ensuring balanced and synchronized movement of the load, even when traversing long distances within the workspace.

Trolley Control: Featuring sensorless vector VFD control technology, the trolley system offers precise speed control and acceleration, allowing for smooth and accurate positioning of loads during material handling operations.

Power Supply: Designed for electric power, the crane operates seamlessly on a standard 230VAC, 3-phase, 60Hz power supply, ensuring compatibility with common industrial electrical systems and easy integration into existing setups.

CMAA Class | Atmosphere | Location Class: Engineered to meet CMAA Class specifications for indoor service in atmosphere class D conditions, the DB40U29-12 is suitable for use in various indoor industrial environments, providing reliable performance in challenging conditions.

Trolley Gauge: With a trolley gauge of 108.0000 inches, the crane offers ample clearance for load movement, allowing for efficient material handling within the workspace without any obstructions.

Beam Size Reference: Detailed beam size specifications are available in the mechanical drawing, ensuring accurate installation and alignment of the crane components for optimal performance.

Approximate Weight: Weighing approximately 4000.00 lbs, the DB40U29-12 strikes a balance between robust construction and manageable weight, ensuring stability and durability during operation.
