The hydraulic oil is pressurized by a vane pump and then passes through a filter, a flameproof electromagnetic reversing valve, a throttle valve, a pilot-operated check valve, and a balance valve to enter the lower end of the hydraulic cylinder. This causes the piston of the hydraulic cylinder to move upward, thereby lifting the heavy object. The return oil from the upper end of the hydraulic cylinder flows back to the oil tank through the flameproof electromagnetic reversing valve. The rated pressure is adjusted by a relief valve, and the pressure value can be observed through a pressure gauge.
When the piston of the hydraulic cylinder moves downward (i.e., the heavy object descends), the hydraulic oil enters the upper end of the hydraulic cylinder through the flameproof electromagnetic reversing valve, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve, the pilot-operated check valve, the throttle valve, and the flameproof electromagnetic reversing valve to return to the oil tank. To ensure a smooth descent of the heavy object and reliable braking, a balance valve is installed in the return oil circuit. The balance circuit maintains the pressure, making the descent speed independent of the weight of the heavy object. The throttle valve is used to adjust the flow rate and control the lifting speed. To enhance the safety and reliability of braking and prevent accidents, a pilot-operated check valve, also known as a hydraulic lock, is added to ensure safe self-locking in case of accidental rupture of the hydraulic pipeline. An overload voice alarm is installed to distinguish between overload and equipment failure.
The hydraulic system of the articulated boom lift is a complex yet highly efficient mechanism. The vane pump serves as the power source, generating the necessary hydraulic pressure. The filter plays a crucial role in removing impurities from the hydraulic oil, ensuring the smooth operation of the valves and cylinders. The flameproof electromagnetic reversing valve allows for precise control of the direction of the hydraulic oil flow, enabling the lift to perform both ascending and descending operations. The throttle valve and balance valve work in tandem to regulate the speed and stability of the lift. The pilot-operated check valve provides an additional layer of safety, preventing any unexpected movement of the load in case of a hydraulic failure. The overload voice alarm is a vital safety feature that alerts the operator in case of an overloaded condition or a potential equipment malfunction.
General Application Scope Articulated boom lifts are widely used in various industries such as municipal engineering, power generation, street lighting, advertising, telecommunications, photography, landscaping, transportation, docks, airports, ports, and large industrial enterprises for installation, maintenance, and elevated work. Their versatility makes them an essential tool in many different fields. For example, in municipal engineering, they are used for tasks such as repairing streetlights, installing traffic signs, and maintaining bridges. In the power industry, they assist in the installation and maintenance of power lines and substations. In the advertising sector, they are used to install and service billboards at high altitudes.
Applications in Specific Terrains and Projects They are suitable for various rugged terrains in the wild and have a wide working range in space. They are mainly used in construction, bridge building, shipbuilding, airports, mines, port terminals, communication and power facility construction, and outdoor advertising engineering machinery and equipment. In building construction, they can reach high areas of the structure for tasks like installing windows, painting, and repairing facades. In bridge construction, they enable workers to access hard-to-reach parts of the bridge for inspection and repair work. In shipbuilding, they are used to work on the upper parts of the ship’s hull and superstructure.
Diesel Articulated Boom Lift The diesel articulated boom lift does not require an external power supply and is ideal for high-altitude erection work in the wild. It is driven by a diesel engine for both movement and lifting. With a powerful engine, it has a relatively fast travel speed. This makes it suitable for projects in remote areas where access to electricity is limited. For instance, in the construction of a new power transmission line in a mountainous region, the diesel articulated boom lift can easily travel to different locations and perform lifting operations without the need for extensive power cable setup.
Trailer Articulated Boom Lift The trailer articulated boom lift can be towed by a vehicle and is synchronized with the vehicle. It is suitable for high-altitude work in the wild. There are two lifting methods: one is using a 380 – 220V power supply, and the other is using a battery to drive the lifting when the power supply is inconvenient. It has an aesthetically pleasing appearance and is convenient for transportation. This type of lift is often used in mobile maintenance and installation teams that need to travel to different job sites. For example, a team responsible for maintaining streetlights in a large area can tow the trailer lift to different locations and use either the power supply or the battery to perform the necessary lifting operations.
Vehicle-Mounted Articulated Boom Lift The vehicle-mounted articulated boom lift is installed on a vehicle and uses the vehicle’s power to drive the lifting. It is suitable for high-altitude work in the wild over long distances. This type of lift combines the mobility of the vehicle with the lifting capabilities of the articulated boom. It is commonly used in industries such as telecommunications and power line maintenance, where workers need to travel long distances to reach different job sites and perform high-altitude tasks. For example, in the maintenance of a long-distance power transmission line, the vehicle-mounted lift can quickly reach the location of a fault and perform the necessary repair work at height.
Bukatzeko, articulated boom lifts play a significant role in modern industrial and construction activities. Their unique working principle and diverse classification applications make them adaptable to a wide range of working conditions and requirements. Whether it is in urban areas for routine maintenance or in remote wilderness for large-scale construction projects, these lifts provide a reliable and efficient solution for elevated work. The continuous development and improvement of articulated boom lifts will further enhance their performance and expand their application scope, contributing to the progress of various industries.
