摘要： A coupler for a wheel loader is used for coupling an attachment (102) to a lifting arm of the wheel loader. A bracket (100) is installed between the lifting arm and the attachment (102). The bracket's back face is pivotally connected to a lifting arm and the bracket's front face is detachably connected to the attachment (102). The attachment (102) has a pair of protrusions (104a,104b) rearwardly extending from the lower back of the attachment (102) and have locking holes pierced through their width. The bracket has a pair of receiving slots (108a,108b) formed at the lower front of the bracket and engaged with the protrusions(104a,104b). The coupler has a shaft (202), and a pair of locking pins (204a,204b) combined with the shaft by threads (216a,216b). The threads (216a,216b) formed at one end of the shaft (202) are right handed and the threads (216a,216b) formed at the other end of the shaft (202) are left handed. When users turn the shaft (202) in one direction,the locking pins (204a,204b) are extended and engaged with the locking holes (a coupling position). When users turn the shaft in the other direction,the locking pins are shortened and released from the locking holes (a release position).

摘要： A data communication gateway for a construction machine communication system, including a first, a second, and a third data interface arranged to be mutually interconnected.
The first interface is arranged to be connected to a private network of a construction machine, the second interface is arranged to be connected to an attachment network, and the third interface is arranged to be connected to an auxiliary network.
A message format table configured in the gateway ECU is indicative of a message formatting relative to a standard message format of the construction machine communication system.
The gateway ECU is arranged to receive a message on a source interface out of the first, second, and third interfaces, translate a data content of the message based on the message format table, and forward a message comprising the translated data content onto a destination interface out of the first, second, and third interfaces.-
