Construction Machinery

     Construction machinery refers to mechanical equipment needed in mechanized operation covering pavement construction and maintenance, earthwork projects, mobile lifting, and handling operation etc. The slip ring, as a key part, has played a large role in such equipment. JINPAT, drawing on decades of skill and experience, has developed many slip rings that have been applied in cranes, excavators, ladder truck, port facilities, and so forth.

     In the field, JINPAT slip rings are able to solve the problems of wires wrapping in operation by improving mechanical performance and simplifying system design. Applied to cranes, the electrical part shares a reliable performance with precise location in its angular ring (a precision up to +/-2°). Multi-circuit design permits its transmission of power, common signal, throttle signal, CANBUS and angle encoder signal, etc. Meanwhile, integrating encoders is supported. JINPAT through hole/bore slip ring model is perfectly suitable for such equipment. They cater to a large lifting capacity of 20T~220T. Moreover, a low torque (1N.m) lowers the torque budget of cranes. Standardized assembly work ensures the consistency of products while the solid contact is secured by scientific structural design, professional manufacture, and stringent checks. As to application in ladder truck, JINPAT slip ring entertains a superb waterproof performance in view of its practical working conditions.

     Internal vibration-resistance design ensures a resistance capacity over 4.5G while low temperature-resistance design allows its operation in a temperature of -50~+120℃. More importantly, all slip rings applied in such a special field have a high protection level up to IP67.
