No.1.Question: Structural components of the steel grab machine: It is necessary to clarify what materials the structural components of the steel grab machine manufacturer are made of. The structural components are related to the wear resistance and durability of the steel grab machine. Our steel grab machine is entirely made of wear-resistant manganese steel plate Q345B material. What brand is the rotary motor of the steel grab and whether the drive mode is column-type drive? The motor of our steel grab adopts a Bulgarian imported motor of brand M S, which has a built-in braking function and an extremely low failure rate. As long as it is not jammed, it can be used for a lifetime. The motor drive is divided into column-type and worm gear type. The column-type has a large torque and fewer failures, while the worm gear type is only suitable for light work. Heavy work can easily cause the worm to deform and bend, resulting in a high failure rate. However, the maintenance cost is low, and the motor is cheap after all!
No.2.Look: Look at the physical object and pictures to see if the overall structural design is smooth, if the structural components are thick and solid, if the welding process is beautiful without slag inclusion, and if there are no defects in full welding. Check if the oil cylinder is self-designed and produced. Generally, the quality of external cooperative supporting products is not controlled by the manufacturer’s quality control, and the quality cannot be guaranteed. If they all have the ability to research and design all components and produce like ours, Then the quality of the steel grabber is guaranteed!
No.3.Touch: Use your hand to feel the key connecting components of the steel grab to check if the fit clearance is tight and there is no shaking! Check if the exterior paint is evenly distributed, if the structural components have undergone anti-rust sandblasting treatment, if the hydraulic oil pipes are not loose, and if there is no oil leakage or dripping at the interfaces!
