Козловой кран двухбалочный У-образный уличный

Введение продукта

The U-type double-girder outdoor gantry crane features a unique "U" shaped frame design. Compared to A-type gantry cranes, it eliminates the need for supporting saddles, providing a wide leg span of nearly 7 meters, facilitating the loading and unloading of large goods such as containers. The crane has a low overall height, strong stability, and can operate along ground rails, offering a wide working range. The main beam can be equipped with cantilevers, supporting operations beyond the span.

It is suitable for ports, railway freight yards, open-air storage yards, and other locations for efficient heavy-duty handling. With a maximum lifting capacity of up to 50 tons, it is a robust, durable, and highly adaptable heavy-duty lifting equipment.

parts of gantry crane

Outdoor gantry crane typically consists of the following main components:

• Продольная балка also known as a large girder, carries hoists and loads over the span. Two types of single and double girders are available.
• Outriggers: Support frames, to connect the main beam to the ground and support vertical loads. It is designed as a box or A-frame and can be fixed or equipped with wheels to move around.
• Lifting mechanism: lifts and lowers the load. Can be equipped with CD/MD wire rope hoists, Euro hoists, or electric trolleys; single/double speed or variable frequency.
• End carriage/wheel: enables the crane to move along the track or yard. Adopt forged steel or cast steel wheels, equipped with a buffer and a derailment protection device to ensure the safety of outdoor operation.
• Crane traveling mechanism: This mechanism drives the entire gantry frame to move along the ground rails. It is usually installed on the end beams and uses an electric motor connected to a gearbox to drive the wheels.
• Electrical system: controls hoisting and traveling operations. Includes control panel, power cord, and braking system.
• Ground rail or rubber tire: supports the crane to move on the ground. Ground rail: suitable for fixed rail. Rubber tires: flexible movement without tracks

Double Girder Outdoor Gantry Crane Features

• Unique U-shaped structure: The saddle-free design provides ample legroom (nearly 7 meters of clearance), allowing for the free passage of large goods and vehicles.
• Высокая грузоподъемность: The double-girder structure ensures powerful lifting capacity and even load distribution.
• Excellent stability: The U-shaped frame combined with a large span design provides superior bending and torsional rigidity and overall stability.
• Efficient operation: The large span provides ample legroom and a wide working range;
• Smooth and precise operation: Soft start and stop are achieved through variable frequency control, reducing shaking.
• Flexible control: Optional pendant control, remote control, or cab operation improves operating precision;
• High safety: Equipped with multiple safety devices (such as limit switches, overload limiters, and emergency stop buttons) to ensure safety and reliability.
• Excellent durability: Key components are made of high-strength steel and advanced welding technology, and the surface is treated with special anti-corrosion treatment, making it suitable for long-term use in harsh outdoor environments.
