In the busy construction hub of Puerto Rico, a mid‑sized earthmoving contractor was losing hours every week to a simple task: changing attachments. Their crews ran excavators from 5 to 20 tons, using buckets, hydraulic hammers, and compactors. Each swap required two workers, a sledgehammer, pin bars, and at least 20 minutes of grunting and hammering. Pins got lost. Bushings wore out. And one worker had already crushed a finger while aligning a bucket.
The owner decided to modernize. He ordered a backhoe quick connect from YG Machinery for his 9‑ton excavator. This Chinese excavator quick coupler uses a hydraulic cylinder and a manual safety lock. Installation took one morning. The first time the operator swapped from a bucket to a breaker, the change took 30 seconds – without leaving the cab.
The result transformed the yard. The crew now changes attachments a dozen times per day without fatigue or injury. The backhoe quick connect paid for itself in labor savings within two months. For a free quote on a Chinese excavator quick coupler for your fleet, contact us today.

Three Problems That Made Manual Attachment Changes A Nightmare In Puerto Rico
The Puerto Rico contractor‘s old method suffered from three universal problems across the Caribbean construction industry.
Problem 1: Lost Time and Wasted Labor
Each manual pin swap took 20‑25 minutes. With six attachment changes per day, that added up to two hours of non‑productive labor. Two workers were tied up for the entire swap, pulling pins and aligning holes.
Problem 2: Safety Risks
Hammering out stuck pins often sent tools flying. One worker crushed his thumb between a bucket ear and the stick. Another dropped a 50kg pin on his foot. The company had already paid two workers‘ compensation claims.
Problem 3: Premature Wear on Pins and Bushings
Manual hammering mushroomed pin ends and ovalized bushing holes. The contractor replaced pin kits every 500 hours instead of the usual 1,500 hours. Each set costs hundreds of dollars.
The Chinese excavator’s quick coupler eliminated all three problems.
How The Backhoe Quick Connect Changed Daily Operations?
The YG hydraulic quick coupler works on a simple principle: the operator pulls a lever (or presses a button on electric‑over‑hydraulic models) to release the locking mechanism. Pins retract hydraulically. The bucket drops off. A new attachment slides on. The pins extend. The operator verifies the safety lock. Total time: under one minute.
30‑Second Swaps
The Puerto Rican crew now changes from bucket to breaker and back without stopping for coffee. The excavator keeps running. The operator never leaves the seat. Production increased by nearly 25% on jobs that required multiple attachment types.
No More Pin Damage
Because the backhoe quick connect uses hardened steel locking pins that engage precisely, there is no hammering. The bucket ears and stick bushings remain like new. The contractor‘s pin and bushing replacement interval extended to over 2,000 hours.
Universal Fit for Different Brands
The contractor runs a mixed fleet – Japanese, Korean, and Chinese excavators. The YG coupler came with adapter brackets for each machine. One Chinese excavator’s quick coupler was swapped between a 9‑ton and a 13‑ton excavator on different days. This flexibility reduced inventory costs.
Real Feedback From The Puerto Rico Contractor
After six months of using the YG60/65 backhoe quick connect, the owner shared his results.
- Time saved per swap: 20 minutes (manual) down to 30 seconds (quick connect) – a 97% reduction.
- Daily productivity gain: Approximately 1.5 extra hours of actual digging per machine.
- Injury incidents: Zero since installation. No more hammering, no more crushed fingers.
- Pin and bushing life: Doubled. The contractor saved $800 in replacement parts in six months.
- Operator approval: The crew refuses to go back to manual pins.
The owner said, “I should have bought this years ago. The Chinese excavator quick coupler is simple – hydraulic pins, a safety latch, and a lever in the cab. But it changed our entire workflow. We take on more jobs because we can switch attachments on the fly. No more excuses about ‘we don‘t have the right bucket on this machine.‘”
An operator added, “I used to dread the moment the dispatcher said ‘swap to the hammer.‘ Now it is a one‑minute job. I pull up, pull the lever, and go. The Chinese excavator’s quick coupler locks tight every time. No wobble, no play.”
