The flexibility and accuracy of the two arms of the wood grabber are not high, which is directly related to the hydraulic components and hydraulic valves used in the wood grabber.
The flexibility and accuracy of the two arms of the wood grabber are not high, which is directly related to the hydraulic components and hydraulic valves used in the wood grabber.
Friends who understand hydraulic systems may understand faster.Different hydraulic components and hydraulic valves have different effects on the wood grabber.Good accessories will inevitably strengthen the various movements of the equipment, otherwise it will affect the flexibility of the whole machine.
The wood grabber adopts hydraulic drive for clamping and handling operations, and is generally suitable for mountainous areas, forest farms and other places.There are many wood grabbers, all of which are modified according to long-term professional needs.After the transformation, the adaptability of cargo handling will be stronger, the efficiency will be greatly improved, and the stability will also provide a stronger guarantee.
Mechanical use is composed of multiple systems, and problems in a certain part will affect the overall operating efficiency.
The following investigation and analysis are carried out on the failure phenomenon of unstable grasping of the wood grabber：
After the faulty parts are found, do not easily replace the new parts, because some parts are not damaged and can be used after cleaning; some have repair value and can be reused after repair.Therefore, when troubleshooting, be careful not to rush to replace, and fully consider whether the root cause of the failure is really eliminated because of the replacement.
Check whether the hydraulic oil level meets the standards, whether the filter element is clogged, and whether the oil grade meets the requirements.If it does not meet the requirements, it should be resolved first.Then, observe whether the oil temperature is too high during work.If it is too high, check the hydraulic oil cooling system to find out the cause and eliminate it.Measure the working pressure of weak parts of the work and compare it with the standard value to judge.
In addition to troubleshooting the cause and replacing parts, all parts of the system must be considered, even the fuel tank will have metal fragments.If it is not cleaned, the machine will be damaged again.Therefore, before replacing the hydraulic system, fuel tank and filter element, the oil and filter element must be cleaned first.
Be very careful when choosing various accessories for wood grabbers.Take the manual valve of the boom crane as an example.Manual valves are mostly dedicated multi-way valves.The flow rate of the multi-channel valve is 60L/min, and the flow channel is 8 channels.The valve is equipped with superimposed overload protection valves on part of the circuit to avoid damage and mechanical failure of hydraulic tubing and hydraulic cylinders caused by equipment overload during operation.The hydraulic valve of the wood grabber is small in size, light in weight, with small valve core clearance and excellent valve core material, which ensures the smooth operation of the hydraulic system.The operating intensity is small, the internal unloading is reduced, the pressure is reliable, and the service life is long.
