1). What warranties do you give?
Warranty: The housing of the machine, wearing part, bracket and hydraulic hose is no warranty, the rest of the machine has one year warranty.
2). Is this direct shaft or belt driven?
They are belt driven. Better motor protection.
3). Does this have a reverse rotation function?
Yes, they have reverse rotation function. Prevent stuck.
4). Can this separate reinforcing bars from concrete?
Yes, the YC series crusher bucket has optional Iron Separator accessory.
5). Can the jaws handle hard rocks? River rocks, etc.?
Yes, they can, below is the river rock crushing video of YC series crusher bucket.

6). What type of steel is used for the bucket, jaws, etc.
NM360 high-strength wear-resistant alloy steel is used for all racks to ensure better wear resistance. NM360 is a kind of steel plate with performance benchmarking HARDOX, but its cost is lower, which can bring better cost performance to users. Jaws use High manganese steel.
7). Do you have instances of the jaws cracking?
No such instances.
8). Is the output size of the debris adjustable?
Yes, YC series crusher bucket can output 10-120mm particles, and the opening size adjustment time is less than 10 minutes, by one people on the job site.
9). What is the capacity (m3/hr.)?
Please find the attached "YC Series Crusher Bucket Output Capacities".
10). Do the bucket pins have T-bushes so that we can attach to different brand excavators?
Yes, T-bushes is OK.
11). Are the hydraulic lines attached to the breaker piping lines of the excavator?
It is different. YC series crusher bucket need the two-way action lines.
12). What accessories are included in the price?
Bracket, hoses, output size adjustment tools are included in the price.
13). Do we need to attach a return line?
If you mean the Drain Line, yes, it needed.
14). I saw that your bucket crushers are belt driven. How many belts are needed? Are these ordinary V-belts? Do the buckets have a belt tensioner? How many hours of use before the belts need to be re-tightened? Replaced? What are the advantages over direct shaft driven?
As I know the transmission structure of the direct shaft driven crusher bucket is that an radial piston motor is directly connected to an eccentric shaft, and then the eccentric shaft directly drives the jaw plate. This structure will lead to each impact force received by the jaw plate in the process of crushing will be transmitted to the motor without reservation, resulting in motor damage or reduced motor life. Especially when the jaw is stuck due to hard objects, it will cause great damage to the motor. The YC series crusher bucket of YICHEN has designed a belt between the motor and the eccentric shaft. In the daily work of the crusher bucket, the belt can be used as a buffer to absorb excess vibration. In extreme cases, the slipping of the belt can also protect the motor.
