Mobile hydraulic equipment is equipped with multiple insurance measures to provide strong protection for the safety of operators. For example, the safety handrail allows operators to have a reliable grip point when working at high altitudes to prevent accidental falls. The safety lock can lock the equipment in time when the equipment stops running or an abnormal situation occurs to prevent accidental start-up or movement. The existence of these safety measures makes operators feel more at ease when using mobile hydraulic equipment and reduces the probability of safety accidents.
(III) High and stable transmission efficiency
The hydraulic transmission system can achieve efficient and stable transmission. Compared with other transmission methods, hydraulic transmission reduces friction loss and improves transmission efficiency. According to the data in the search material, hydraulic transmission has many unique advantages over other transmission methods. Under the condition of transmitting equal power, the hydraulic device has the smallest volume, a lightweight, and compact structure. At the same time, the hydraulic system can easily achieve a wide range of step-less speed regulation through flow control, and the speed regulation range can reach 2000:1. The speed can also be adjusted during the working process. This efficient and stable transmission characteristic enables mobile hydraulic equipment to perform well in various operating scenarios.
(IV) High transmission power
Hydraulic transmission has a strong power output capacity and is very suitable for mechanical equipment that transmits large torque and high speed. For example, in the field of engineering machinery, the hydraulic system can drive large hydraulic cylinders to achieve powerful excavation, lifting, and other actions. Compared with electric motors, the weight of hydraulic motors with the same power is only 10%-20% of that of electric motors, but it can output greater torque. This makes hydraulic transmission have obvious advantages in situations where high power output is required.
(V) Simple operation and easy control
The hydraulic transmission system is easy to operate and can control the liquid flow and pressure by adjusting the hydraulic valve to achieve step-less speed regulation and accurate control. Operators only need to be familiar with simple operating procedures to control the operation of the equipment easily. Whether in construction, warehousing, logistics, or industrial production, this easy-to-control feature makes the use of mobile hydraulic equipment more convenient and quicker. At the same time, the hydraulic system can also cooperate with electrical control to achieve remote control, further improving the convenience and safety of operation.
(VI) Wide range of applications
The hydraulic transmission system can adapt to different working environments and working conditions and has a wide range of applications. Whether in harsh environments such as high temperature, low temperature, humidity, or dust, the hydraulic system can work stably. For example, in the steel industry, hydraulic transmission systems can be used for metallurgical machinery, lifting devices, and other equipment; in civil engineering and water conservancy projects, they can be used for flood control gates and dam devices, riverbed lifting devices, etc. This strong adaptability has made mobile hydraulic equipment widely used in various fields.
(VII) Smooth and reliable operation
The mobile hydraulics transmission system has good anti-interference and stability and runs smoothly. During the operation of the equipment, the vibration is kept to a minimum, and will not cause adverse effects on the surrounding environment and operators. At the same time, the hydraulic system also has an overload protection function. When the load exceeds the system’s bearing capacity, the system will automatically unload and protect the equipment from damage. For example, in a mobile hydraulic lift, when overloaded, the safety device will automatically start to prevent equipment failure.
(VIII) Flexible and convenient layout
The layout of hydraulic components is not strictly restricted by spatial position, which makes it easy for the hydraulic system to form a complex system and adapt to the needs of mobile machinery. In mobile equipment, space is usually limited, and hydraulic components can be flexibly arranged according to actual conditions to make full use of limited space. At the same time, the hydraulic system can connect various components through pipes and hoses, eliminating layout problems and making the design of the equipment more concise and efficient.
