Jiangtu Fully Automatic Double Locking Hydraulic Quick Hitch Coupler

This quick hitch coupler can help the excavator to realize fully automatic and quickly changeable various attachments such as buckets and breakers in the cab.

Inspired by the German hitch coupler, Jiangtu engineers have developed this product with national utility model patents, appearance patents, and European CE certification through continuous research and development, improvement, and market verification.

It is currently sold well in European and American countries. The most prominent advantage of Jiangtu’s fully automatic double-locking hydraulic quick hitch coupler is safety.

It cancels the hand-inserted safety pin based on the safety of an ordinary hydraulic quick hitch coupler. The safety spring and safety hook together form a double safety guarantee against failure.

The linkage safety block is installed at the rear hook of the hitch coupler (as attached photo). If the front hook or the piston rod of the cylinder breaks, the safety hook can lock the top pins of the bucket to prevent the bucket and other accessories from falling and causing danger.

The safety spring is another important guarantee.

When there is a problem such as internal leakage of the oil cylinder, if there is no safety spring, the oil cylinder will retract and drive the safety hook to retract, the hitch coupler and the attachment will be easily separated, and the safety spring will stop the retraction of the oil cylinder and the safety hook to achieve the purpose of protection.

In addition, a safety valve is built into the cylinder, to prevent the cylinder from shrinking, forming multiple safety guarantees.

In addition, the design structure of the Jiangtu fully automatic double locking hydraulic quick hitch coupler makes the force point on the lower plate, compared with the force point of the ordinary quick hitch coupler on the cylinder piston rod, which can reduce the loss of the oil cylinder, prolong the life of the oil cylinder, and thus prolong the life of the oil cylinder.

Because of this, Jiangtu’s after-sales service solemnly promises: a six-month replacement and a one-year warranty; this after-sales guarantee is beyond the reach of other hitch coupler brands in the Chinese market.

Other advantages:

  • Using high-strength manganese steel and advanced mechanical design of structural integration, it is durable;
  • Mature products and complete models, suit to 0.8-52ton excavators;
  • Compared with European and American products, our fully automatic double-locking hydraulic quick hitch coupler has a rear hook that is made of round steel, which is stronger, more durable, and break-resistant. Meanwhile, the hook has added guide plates, hanging buckets, and other accessories more convenient;
  • The body length of the new optimized fully automatic double locking hydraulic quick hitch coupler is much shorter than the old one, which increases the convenience of construction in narrow spaces.
  • Under the high-precision process of assembly, welding, and boring, take the dipper 250-260mm of JT-06 quick hitch coupler as an example, and widen the front movable hook to 245-255mm, which is 5mm less than the dipper size. By analogy, a gap of 2.5 mm on one side is achieved when hanging the hammer or bucket to prevent the gap from being too large to wear too quickly, and to prevent the hammer loop from falling out.
  • Unique solenoid valve and small iron pipe base: The solenoid valves have no failure for all sold hydraulic quick couplers; the casting base of iron pipe is beautiful and sturdy, and other manufacturers are screwed on and easy to fall off.
  • Pipeline kits and other accessories are the best.
