Introduction to On-Board Lifting Trucks
- Basic Concepts
- Definition:&bsp;A truck-mounted crane, often simply referred to as an on-board crane, is an innovative piece of equipment designed to enhance the mobility and efficiency of lifting operations. Utilizing a sophisticated hydraulic lifting and telescoping system, it seamlessly performs the lifting, rotating, and hoisting of goods, and is typically mounted on a truck.
- Function Advantages:&bsp;This remarkable machinery combines the dual functions of lifting and transportation, enabling it to independently manage the entire process of moving and handling goods. Unlike traditional cranes that require separate trailers for transport, this solution significantly reduces both time and manpower requirements.
- Structural Composition
- Truck Chassis:&bsp;A wide range of brands and models are at your disposal, including Dongfeng, Heavy Duty Truck, Shaanxi Automobile, Jiefang, Ouman, Steyr, and more. Each chassis offers varying load capacities, power performance levels, and wheelbases to accommodate diverse operational requirements.
- Truck:&bsp;Designed for efficient goods loading, the truck can be tailored with varying lengths and volumes to satisfy the transportation requirements of different types of cargo.
- Traction Device: This component is the vital link between the engine and crane, adeptly regulating the power transfer and cessation from the engine to the crane, thus ensuring optimal operation.
- Crane:Serving as the central component of the on-board crane truck, cranes are categorized by manufacturer-such as Zoomlion, Xinfeigong, Chengli-and further differentiated by type, including straight arm and folding arm. Available in specifications from 2 tons to 30 tons, they are customizable to meet specific lifting needs.
- Operational Principle
- Hydraulic System: The hydraulic system is the core powerhouse of the truck-mounted crane, driving all crane movements through the precise pressure transmission of hydraulic oil. It seamlessly facilitates the extension and contraction of the lifting arm, as well as the hoisting mechanism's amplitude, rotation, and lifting operations.
- Control System:&bsp;The crane's control system allows for precise management of various movements. Within the operation room, operators can adjust the hydraulic valve's opening and flow via joystick or remote control, ensuring the crane's actions are executed with precision and facilitating safe, efficient lifting operations.
- Characteristics of Different Types
- Straight Arm Crane:&bsp;Designed with a telescopic, section-by-section extending arm akin to an antenna, this crane boasts an impressive working radius and high lifting capabilities, making it ideal for high-altitude tasks such as installing billboards or bridge construction, albeit with reduced flexibility in confined spaces.
-
- Refrigerated Crane:&bsp;Featuring a folding, jointed arm, the refrigerated crane excels in flexibility, allowing 'flash and move' operations in tight spaces. Perfect for tasks like warehouse management and interior decoration requiring precise lifts, it's generally pricier than its straight-arm counterparts of equivalent tonnage
- Application Areas
- Logistics Transportation: In bustling logistics centers, ports, and freight stations, this crane is instrumental in the swift loading and unloading of goods, dramatically enhancing overall logistics efficiency by seamlessly transferring cargo from transport vehicles.
- Construction:&bsp;A trusted ally on construction sites, it adeptly lifts and transports essential building materials such as steel bars, cement, and bricks, while also proving invaluable for the installation and dismantling of construction equipment.
- Municipal Engineering:&bsp;Engage seamlessly in urban infrastructure endeavors such as street lamp installation, telephone pole erection, billboard mounting, and a plethora of other high-altitude operational tasks.
- Emergency rescue and relief efforts: In the midst of earthquakes, fires, debris flows, and other disaster scenarios, this crane excels at removing obstacles, transporting vital rescue supplies, and safely hoisting injured individuals, serving as an indispensable tool in rescue missions.
- Operational guidelines and safety measures
- Personnel qualifications:&bsp;The crane operator is required to complete specialized safety training, securing approval from relevant authorities, and obtaining a qualification certificate prior to solo operation. Unauthorized personnel are strictly forbidden from using the crane equipment.
- Pre-operation inspection checklist: Prior to commencing operations, a thorough inspection is imperative to ensure all operating devices are functioning normally, the wire rope meets safety standards, and the brake, hydraulic system, and safety devices are intact, responsive, and reliable. It is strictly forbidden to operate equipment with any malfunctioning parts.
- Guidelines for lifting arm usage: The lifting arm must maintain a minimum angle of 30°. The crane should minimize lifting and lowering of the arm under load, and it is strictly prohibited to alter the control lever until the lifting arm achieves stability.
