Introduction to On-Board Lifting Trucks
- Basic Concepts
- Definition:A truck-mounted crane, often referred to simply as a truck-mounted crane, is a marvel of modern engineering. It facilitates the seamless lifting, rotation, and hoisting of goods, all thanks to a sophisticated hydraulic lifting and telescoping system. Typically, this state-of-the-art equipment is mounted on trucks, making it an indispensable tool for heavy lifting tasks.
- Function Advantages:This ingenious equipment combines both lifting and transportation functions, enabling it to single-handedly manage the transportation, loading, and unloading of goods. Unlike traditional cranes that often require additional trailers, this crane dramatically reduces time and labor costs.
- Structural Composition
- Truck Chassis:A variety of brands and models are available, including Dongfeng, Heavy Duty Truck, Shaanxi Automobile, Jiefang, Ouman, and Steyr. Each chassis offers distinct load-bearing capacities, power performances, and wheelbase specifications to cater to diverse operational requirements.
- Truck:&bsp;Designed for efficient loading of goods, these trucks can be customized with varying lengths and volumes to suit an array of transportation needs.
- Traction Device: This device seamlessly connects the engine to the crane, orchestrating the power output and transfer from the engine to the crane, thus powering its operations.
- Crane:The crane is the pivotal component of the on-board crane truck. Depending on the manufacturer, options include Zoomlion, Xinfeigong, Chengli, and others. By type, they are categorized into straight arm and folding arm cranes, and by tonnage, they offer specifications ranging from 2 to a staggering 30 tons.
- Operational Principle
- Hydraulic System: At the core of the truck-mounted crane lies its hydraulic system. It powers every movement of the crane through the pressure-driven transmission of hydraulic oil, enabling actions such as the extension and contraction of the lifting arm, amplitude, rotation, and the swift lifting of the hoisting mechanism.
- Control System:The crane offers precision in controlling a variety of movements. Operators can deftly manage the opening and closing of hydraulic valves and adjust flow sizes through a joystick or remote controller, ensuring the crane's actions are executed with precision, safety, and efficiency.
- Characteristics of Different Types
- Straight Arm Crane:With a lifting arm that extends like a telescopic antenna, this crane boasts an impressive working radis and high lifting height, making it ideal for high-altitude tasks such as billboard installations and bridge construction. However, it may have limited maneuverability in confined spaces.
-
- Refrigerated Crane:&The flexible folding and bending of its lifting arm allow it to 'weave and maneuver' in tight spaces, perfect for tasks demanding precise lifting such as warehouse handling and interior decoration. Note that this versatility typically comes at a higher cost compared to a straight arm crane of the same tonnage.
- Application Area
- Logistics Transportation: In logistics warehouses, ports, and freight stations, these cranes excel at the rapid loading and unloading of goods from transport vehicles, significantly boosting logistics efficiency.
- Construction:Expertly lifting and transporting construction materials like steel bars, cement components, and bricks on construction sites, these cranes are also adept at installing and dismantling construction equipment.
- Municipal Engineering:Engage in a wide array of urban infrastructure developments, beautifully enhancing cityscapes with tasks like street lamp installations, erecting telephone poles, setting up billboards and executing various high-altitude operations with remarkable precision and efficiency.
- Rescue and Relief: Amidst the chaos of disasters like earthquakes, fires, and debris flows, this product shines as a beacon of hope. It adeptly clears obstacles, transports vital rescue materials, and expertly hoists injured individuals, playing an indispensable and heroic role in emergency rescue missions.
- Operation Precautions
- Personnel Qualification:The crane operator must undergo thorough professional safety training, achieving approval from relevant authorities through examination. Only after securing a certificate of qualification are they permitted to operate independently. This rigorous process ensures that only licensed personnel handle the crane equipment, maintaining the highest standards of safety and operation.
- Pre-operation Inspection: Prior to embarking on tasks, it is essential to meticulously inspect each operating device to ensure normal functionality. This includes verifying the integrity of the wire rope against safety standards, and confirming that brakes, hydraulic mechanisms, and safety devices are complete, sensitive, and reliable. Operating machine parts in a compromised state is strictly forbidden, safeguarding the entirety of the operation.
- Use of the Lifting Arm: The elegance of the lifting arm requires maintaining an angle no less than 30°. For optimal safety, minimize the lifting and lowering of the arm under load. It is absolutely imperative to avoid altering the control lever until the lifting arm has achieved complete stability, ensuring smooth and secure operations.
