Mini excavator preheating should pay attention to matters

Mini excavator hydraulic device preheating, hydraulic oil temperature is low, if the rapid operation will cause hydraulic device damage. Here's a quick summary:1. The mini excavator engine runs at medium speed, operates the bucket, and preheats;2. Jack up the machine to rotate the track, and preheat the left and right walking motors respectively;3. Then, increase the speed of the engine, so that the bucket and bucket rod work continuously for 5 minutes;At the same time, preheating operation should pay full attention to the safe environment around, when the temperature is low, people's response will be relatively slow, to prevent in the preheating time to meet people and things around.

Mini excavator snow rolling brush main application

The snow sweeping roller brush installed on a small excavator has obstacle crossing function, which can effectively handle various types of snow and ice on road surfaces, such as floating snow, thin snow, and thin ice. At the same time, it can drive, operate, and avoid obstacles on uneven roads, with high work efficiency.The interchangeable quick connection mechanism of the snow sweeping roller brush makes the installation and disassembly of the snow sweeping roller brush and the vehicle simple and convenient, and the operation is safe and reliable; In snow removal operations, the snow sweeping roller brush automatically adjusts the obstacle avoidance protection function according to the undulating slope of the road surface.1、 Snow sweeping and rolling brush application:Suitable for northern regions of China, this machine is compact, flexible, and multifunctional. It is widely used as a necessary machinery for winter snow removal in government agencies, units, schools, parking lots, squares, property communities, gardens, non motorized lanes, and other areas. It cleans quickly and greatly saves manpower.2、 Features of snow sweeping and rolling brush:High quality bristlesThe bristle material is a mixture of fully plastic bristles imported from the UK and elastic steel wire, which has high tensile resistance, fracture resistance, light weight, and better elasticity.Rubber wheelThe support wheel of the rolling brush adopts double-sided single wheel rubber wheels, making the main body of the rolling brush have a longer service life.Motor direct connectionThe motor is directly connected, with high transmission efficiency; Built in installation for safer operation.

How to use mechanical quick change for mini excavators

Mechanical quick change, fixed by manually tightening the top screw with a wrench, usually used on small excavators.   Due to the different operating conditions of excavators, it is often necessary to install and switch various working devices on excavators, such as excavators, crushing hammers, wood grabbers, scarifiers, etc. This type of accessory that can quickly replace the working device, called a quick connector, can quickly disconnect and install various accessories, and can stably and effectively lock the working device. It improves the replacement efficiency of small excavators for replacing accessories such as excavators, crushing hammers, and spiral drills.   Working principle of mechanical quick change   By rotating the mechanical screw to adjust the distance of the movable block, the ability to disassemble and install the working components of the excavator is achieved.   Mechanical Quick Change Features   Advantages: Simple structure, low cost, no need to modify the pipeline, can be installed on the shaft for use;   Disadvantages: Due to the long-term high-strength reciprocating movement of the working components of the excavator, it is easy to cause mechanical screws to loosen and thread damage.
