If you have ever tried to excavate loose material from underwater, clean out a drainage ditch, or handle loose aggregate in a confined area with a standard excavator bucket, you know the frustration. The bucket spills material. It doesn’t close tightly enough to hold loose contents. You lose half your load before you even reach the dump truck.
Standard excavator buckets are designed for digging and scooping, not for grabbing and carrying loose or underwater materials. They leave a trail of spilled material behind them, wasting time and reducing productivity. In applications like river dredging, canal cleaning, foundation excavation, and loose material handling, a standard bucket simply isn’t the right tool.
A clamshell bucket for mini excavator is the solution. It’s a two-shell grabbing bucket that opens and closes like a clam. The hydraulic cylinders pull the two shells together, creating a tight seal that holds loose material securely. The bucket can be rotated and positioned precisely, making it ideal for vertical excavation, trenching, dredging, and handling loose aggregates. Unlike a standard bucket, a clamshell grabs material from the top down, allowing you to work in confined spaces and underwater.
YG Machinery offers four clamshell buckets for mini excavator models: YGCS04, YGCS06, YGCS08, and YGCS10, covering excavator classes from 7 tons up to 35 tons. They feature high-strength steel construction, tight-closing shells that prevent material spillage, 360-degree rotation capability, and hydraulic cylinders with built-in safety valves. They have extremely low maintenance requirements, significant productivity advantages over standard buckets in loose material applications, and durable construction that lasts for years in demanding conditions. They are suitable for different excavator sizes and project scales – from small foundation digging to large-scale dredging and canal cleaning – and are a highly reliable choice for contractors who need to handle loose, granular, or underwater materials efficiently.
But with four sizes and multiple configurations, how do you choose the right one? In this head-to-head comparison, we pit YG’s four clamshell buckets for mini excavator models against each other and against standard buckets and hydraulic grabs, focusing on excavator compatibility, weight, opening width, working pressure, and project suitability.
Technical Specifications Of YG Clamshell Bucket For Mini Excavator Models
All four models are hydraulic clamshell buckets designed for mounting on excavators from 7 to 35 tons. Below are the core parameters.
| Item/Model | Unit | YGCS04 | YGCS06 | YGCS08 | YGCS10 |
| Suitable Excavator | ton | 7-11 | 12-18 | 18-25 | 26-35 |
| Weight | kg | 800 | 1200 | 2000 | 2300 |
| Opening | mm | 1000 | 1500 | 2200 | 2300 |
| Working Pressure | bar | 180 | 210 | 250 | 250 |
| Set Up Pressure | bar | 250 | 290 | 320 | 340 |
| Working Flow | lpm | 190 | 210 | 220 | 240 |
All models feature high-strength steel shells, hydraulic cylinders with overload protection, and pivot points with grease fittings for easy maintenance. The opening width ranges from 1000mm on the smallest model to 2300mm on the largest.
YG Clamshell Buckets vs Standard Buckets And Hydraulic Grabs
Many contractors try to use standard buckets for loose material and underwater work. Others reach for hydraulic grabs. Neither approach is ideal. Let us break down four critical dimensions and compare YG clamshell buckets to these alternatives.
Material Retention and Spillage Control: A standard bucket has an open top. When you scoop loose material like sand, gravel, or dredged silt, the material spills out the sides and back as you lift and swing. You lose 20-30% of your load before reaching the dump point. A hydraulic grab has tines or claws that don’t form a complete seal, allowing fine material to fall through the gaps. A clamshell bucket for mini excavator closes into a completely sealed shell. The two halves meet along the entire edge, forming a tight seal that holds even the finest material. You carry your full load from grab to dump, with zero spillage.
Underwater and Wet Material Performance: Standard buckets can dig underwater, but they stir up sediment and can’t hold material effectively. The material slides off the bucket as it is lifted through the water. Hydraulic grabs suffer from the same problem – gaps between the tines allow material to wash out. A clamshell bucket’s sealed shell holds material even when lifted through water. The hydraulic cylinders close the shells with enough force to maintain the seal against water pressure and material weight. This makes it the preferred tool for river dredging, canal cleaning, and underwater foundation work.
Reach and Positioning in Tight Spaces: A standard bucket excavates by pulling toward the machine. In tight spaces – between building foundations, in narrow trenches, or inside pipe trenches – the bucket can’t reach far enough or position itself correctly. A clamshell backhoe bucket works vertically. The shells open and close in line with the stick, allowing you to reach straight down into narrow excavations. You can grab material from the bottom of a deep, narrow trench without repositioning the excavator. This saves time and reduces site disturbance.
Precision and Control: Standard buckets are coarse tools. You dump material in a pile and then spread it. Hydraulic grabs offer some control, but the tine spacing limits the minimum material size. A clamshell bucket provides precise control over the grab volume. You can open the shells partially to take small bites or fully to take a large bite. The hydraulic system with built-in safety valves prevents sudden closure, protecting the bucket and the excavator from shock loads.
Core Advantages Of YG’s Clamshell Bucket For Mini Excavator Over Standard Buckets And Grabs
Why do contractors working in loose material and underwater applications switch to YG clamshell buckets? Four strong reasons.
- Zero Spillage – Carry Full Loads Every Time: The tight-closing shells of a YG clamshell bucket form a complete seal along the entire edge. This means no material falls through, no material spills over the sides, and no material washes out during transport. Every cycle moves a full bucket of material from the grab point to the dump point. On a typical job, this translates to 20-30% higher productivity than a standard bucket.
- High-Strength Steel Construction – Built for Tough Conditions: YG clamshell buckets are fabricated from high-strength steel with reinforced wear plates at high-wear areas. The shells are designed to withstand the impact of heavy material and the abrasion of sand, gravel, and dredged material. The pivot points are fitted with hardened bushings and grease fittings for easy maintenance. With regular greasing and inspection, a YG clamshell bucket lasts for years of daily use.
- Hydraulic Cylinders with Built-in Safety Valves: The hydraulic cylinders on YG clamshell buckets include overload protection valves. If the bucket encounters an immovable object or the operator closes the shells with excessive force, the safety valve releases pressure to prevent damage to the cylinder, the bucket, or the excavator. This feature extends the service life of both the bucket and the machine.
- Compatibility with Standard Excavator Hydraulics: YG clamshell buckets are designed to work with standard excavator hydraulic systems. The working pressure and flow requirements (180-250 bar, 190-240 lpm) match the output of most excavators in the 7-35 ton class. No special hydraulic modifications are required. The bucket mounts to the standard quick coupler or pin-on system, so you can switch between bucket types in minutes.
