Mr. Zhang does earthmoving work in Ghana. Three excavators. Every day, switching between breaker, bucket, ripper — back and forth, a real hassle. He came to us for a quote last year but hesitated for three months. A few days ago, he contacted us again and said, “The money I lost in those three months could have bought two quick couplers.”
He did the math: each excavator changed attachments three times a day, wasting 20 minutes each time. Three machines, 180 minutes a day. Over three months (80 working days), that is 14,400 minutes — 240 hours. At local labor rates, the money burned was exactly the price of two excavator coupler units.
We don‘t want to see you lose money like that. So this article is not a lecture. We just want to show you how our excavator quick hitch for sale can earn that money back for you.
From 20 Minutes To 30 Seconds — What Changed?
Without a quick coupler, changing attachments is a workout: stop the machine, turn it off, find a pry bar, hammer out the pins, align the holes, hammer again. Twenty minutes if you are lucky. If the pins are rusted, half an hour.
With an excavator coupler, the process becomes: sit in the cab, flip a switch. The solenoid valve opens, hydraulic oil flows into the cylinder, and the jaws open. Hook the new attachment, flip the switch back, and the jaws close and lock. Don‘t even look at the clock — less than half a minute.
We use imported solenoid valves for fast response. The cylinders are made in‑house with good seals for crisp action. Working pressure 32‑40 bar, flow 10‑20 L/min — that’s the standard pilot circuit range on any excavator. So no matter what brand you run, it plugs right in.
Whatever Your Excavator Size, We Have A Matching Model
Mr. Zhang‘s three excavators were 6 tons, 15 tons, and 23 tons. We matched them with three models.
| Excavator size | Recommended model | Coupler weight (kg) | Pin-to-pin center (mm) | Cylinder stroke (mm) |
| 6 tons | YG45 | 50-60 | 230-270 | 205-275 |
| 15 tons | YG60/65 | 120-130 | 380-420 | 340-486 |
| 23 tons | YG70/80 | 280-290 | 460-480 | 256-390 |
He asked: “My attachment pin diameter is 70mm. Will it work?” Yes. Pin diameters from 25mm up to 120mm — we have matching bushings and pins. You don‘t need to fabricate anything. We supply everything.
Afraid The Attachment Might Fall Off? Our Design Is More Scared Than You
Mr. Zhang hesitated at first because he was afraid of dropping an attachment. “If a breaker falls off, that’s tens of thousands of dollars gone,” he said.
We showed him the jaw structure: after closing, the cylinder maintains pressure. Even if a hydraulic line bursts unexpectedly, a mechanical self‑locking mechanism still grips the pins tightly. To convince him, we did a live test: after mounting a bucket, lifting it half a meter off the ground, pry the bucket edge with a steel bar. It wouldn‘t budge.
Then he signed the contract.
Safety is not about words. It‘s about structure. Every excavator coupler is load‑tested before leaving our factory. What you get is a certificate of confidence.
Installation? We’ll Walk You Through It
Mr. Zhang‘s excavators were in Ghana, and we couldn‘t send a technician. So what did we do?
We filmed the installation step by step, with annotations. He found a local mechanic, played the video, and followed along. The first machine took half a day. The next two took only two hours each.
Every coupler ships with a complete kit: pins, bushings, hydraulic fittings, and seals. You don‘t need to buy anything extra.
If you still have trouble, we can do remote video guidance. If necessary, we can send an engineer to your site.
Who Benefits The Most?
- Site owners who change attachments more than twice a day
- Rental companies that supply excavators with operators (if the driver wastes time changing attachments, you pay double)
- Municipal, tunnel, and demolition contractors (constantly switching between breaker and bucket)
- Quarries and mines (breakers wear out fast and need frequent changes)
If you change attachments fewer than 50 times a year, you might not need one. But if you change them every day, every day you wait is another day of Mr. Zhang‘s regret.
One Reason Not To Hesitate
All you need to do is tell us your excavator size and attachment pin diameter. We will provide the matching proposal, quotation, installation videos, and a complete set of accessories (pins, bushings, hydraulic fittings).
The attachment lists seven models with clear parameters, covering excavators from 1.5 tons up to 45 tons. Choose the right model, install it properly, and save that one hour of attachment change time every day — that is real profit.
Use the time you save to take on the next job, drink tea, or go home early. Anything is better than kneeling beside the cab and hammering pins.
