There are many kinds of excavator wood grapple in our country, there are mechanical, hydraulic rotary, single cylinder grapple, double cylinder grapple on the market at present, the quality is also uneven, how do customers make a wise choice?
Firstly, it is the weight of excavator wood grapple: Through the weight of the wood grab to judge whether cutting corners, although our company can also use high-quality steel to achieve light and durable, but the current national price has not allowed to significantly increase the cost of production to obtain customers, after all, the price is the past, the current situation only recognize the price, you can only judge the equipment through the weight of the equipment is high strength, durable!
Secondly :It is the outline size diagram: through the outline size diagram to compare the technical parameters of various manufacturers, such as the opening size, height and width of excavator wood grapple, whether the finished product photos produced are proportional and coordinated, whether the cylinder is with a balanced pressure retaining valve, whether the motor is with a protective valve block, whether the valve block is a good brand or imported brand, whether the hydraulic parts such as the cylinder has protective structural parts and so on.
Thirdly :it is the hydraulic pipe and control system of the wood grapple: these are the accessories that customers can't see or ignore, good hydraulic pipe iron pipe after pickling phosphating process without rust and no impurities, seamless steel pipe material good wall thickness, hose are imported or joint venture brand four-layer steel pipe, electric control system wiring harness all use air plug link waterproof sunscreen, external use of mesh structure anti-tensile, Optimize the simple without complicated control box, such as the solenoid valve with excellent brand, with fine clearance, reduce the phenomenon of stuck valve and oil leakage.
