It also finds use in industrial settings for loading and unloading heavy machinery, making it an indispensable asset for various industries that require efficient and reliable heavy – lifting solutions.

VLASTNOSTI

1. Introduction

The Dongfeng 11.4 Tuny nákladní teleskopický jeřáb je pozoruhodný kus těžké – duty equipment designed to meet the demanding needs of various industries. Combining the reliability of the Dongfeng truck chassis with the functionality of a high – capacity telescopic crane, it offers a wide range of features that make it stand out in the market.

2. Chassis and Mobility

2.1 Dongfeng Truck Chassis

The crane is built on a Dongfeng truck chassis, which is known for its robustness and durability. The chassis provides excellent stability during transportation and operation. It is engineered to handle the heavy load of the crane structure and the maximum lifting capacity of 11.4 tun. The truck’s suspension system is designed to absorb shocks and vibrations, ensuring a smooth ride even on rough terrains. This enables the crane to be easily transported to different job sites, whether it’s a construction site in an urban area or an industrial project in a more remote location.

2.2 Mobility Features

Equipped with powerful engines, the Dongfeng truck chassis offers sufficient power for the crane to move at an efficient speed. The vehicle’s transmission system is optimized for smooth gear shifts, allowing for easy acceleration and deceleration. The turning radius of the truck is carefully designed to provide good maneuverability, making it possible to navigate through narrow construction sites or congested industrial areas with relative ease. Navíc, the braking system is reliable and responsive, ensuring the safety of the vehicle and its surroundings during transportation.

3. Telescopic Crane Structure

3.1 Telescopic Boom Design

The telescopic boom of the crane is a key feature. It is made of high – strength materials that can withstand the heavy loads during lifting operations. The boom has multiple telescopic sections that can be extended or retracted smoothly. This allows for variable working radii and lifting heights, providing great flexibility in operation. The telescopic mechanism is precise and reliable, ensuring that the boom can be adjusted to the desired length with accuracy. The surface of the boom is usually treated to resist corrosion, prolonging its service life.

3.2 Lifting Capacity and Range

With a maximum lifting capacity of 11.4 tun, the crane can handle a wide variety of loads. The lifting range is extensive, both in terms of height and horizontal reach. This enables it to be used for tasks such as loading and unloading heavy equipment, installing structures at construction sites, and assisting in industrial maintenance operations. The crane’s load – moment indicator system constantly monitors the load and the position of the boom to ensure safe lifting operations within the specified capacity limits.

4. Control System

4.1 Operator’s Cab

The operator’s cab of the Dongfeng 11.4 Tuny nákladní teleskopický jeřáb is designed with the operator’s comfort and convenience in mind. It is equipped with ergonomic seats and controls. The cab provides a good view of the working area, allowing the operator to have clear visibility during lifting and transportation operations. The control panel inside the cab is intuitive and easy to operate, with clearly labeled buttons and joysticks for boom extension, rotation, and lifting functions.

4.2 Advanced Control Technology

The crane incorporates advanced control technology. The hydraulic control system is highly responsive, enabling smooth and precise movements of the boom. The control system also features safety interlocks to prevent incorrect operations. Například, it will prevent the boom from being extended beyond its safe working range or the crane from lifting a load that exceeds its capacity. This ensures the safety of the operator, the equipment, and the surrounding environment.

5. Bezpečnostní funkce

5.1 Overload Protection

As mentioned earlier, the load – moment indicator system provides real – time information on the load and boom position. When the crane approaches or exceeds its maximum lifting capacity, alarms will sound, and the control system will restrict further operations to avoid dangerous situations.

5.2 Stability Control

During operation, the crane’s stability is crucial. Sensors are installed to monitor the stability of the vehicle and the crane structure. If any instability is detected, such as uneven ground conditions or excessive load on one side, the control system will take appropriate measures, such as adjusting the outriggers or limiting the movement of the boom to maintain stability.

5.3 Emergency Stop System

An emergency stop button is conveniently located within the operator’s reach inside the cab. In case of any emergency, the operator can immediately stop all operations of the crane to prevent accidents.

6. Závěr

The Dongfeng 11.4 Tuny nákladní teleskopický jeřáb combines a reliable truck chassis with an efficient telescopic crane structure, advanced control systems, and comprehensive safety features. Its mobility, zvedací kapacita, and ease of operation make it an ideal choice for a wide range of applications in construction, industrial, and other heavy – duty industries, providing users with a high – performance and dependable solution for their lifting and transportation needs.
