Une cisaille hydraulique à deux cylindres qui simplifie les tâches de démolition et de recyclage

In modern building demolition, waste recycling, and urban renovation, efficiency and safety are critical. Traditional demolition methods are time-consuming, labor-intensive, and risky. The dual-cylinder hydraulic shear，as a key excavator hydraulic shear attachment, offers stable structure and high-performance hydraulic control, making it a trusted tool for construction teams worldwide. It is suitable for building demolition, steel and concrete cutting, and scrap handling. With hydraulic rotation and precise operation, teams can work efficiently in complex environments, enhancing productivity and safety. For both large-scale demolitions and disaster rescue, the DEVELON hydraulic shear has proven to be indispensable.

1. Overview of Dual-Cylinder Hydraulic Shear

The dual-cylinder hydraulic shear is designed for medium to large excavators, compatible with 20–38 ton DEVELON and DOOSAN excavators. It features a robust structure with a total weight that includes hydraulic rotation and speed control, excluding the mounting adapter, hydraulic hoses, accessories, and pins. Maximum length excludes the adapter when jaws are fully open or closed, allowing flexible and safe operation on site.

The shear offers multiple jaw types, including crusher jaws, pulverizing jaws, demolition jaws, and steel cutting jaws, making it suitable for concrete, steel, and general waste demolition. Its stable hydraulic system and hydraulic demolition shear functionality allow operators to achieve precise positioning and efficient work even in tight spaces.

Key Features:

• Heavy-duty, durable structure for long-term high-load operations
• 360° hydraulic rotation for complex site conditions
• Multiple jaw types, covering building demolition and steel cutting hydraulic shear
• Easy maintenance design reduces downtime and supports hydraulic shear maintenance tips

2. Application Scenarios

2.1 Building Demolition

In demolishing old buildings or commercial structures, operators often face complex layouts and high-risk conditions. The dual-cylinder hydraulic shear can efficiently cut through concrete walls and steel beams, a prime example of concrete cutting shear for excavator use.

Advantages:

• High-strength hydraulic cutting force for fast material processing
• Hydraulic rotation enables flexible and precise operation
• Stable structure reduces risk in high-elevation work
• Ideal for construction site hydraulic shear tasks

2.2 Waste Recycling

At recycling facilities, the shear efficiently cuts scrap steel and concrete blocks, facilitating sorting and transportation, functioning as a reliable excavator scrap metal shear.

Advantages:

• Precise cutting improves material recycling rates
• High-efficiency hydraulic control reduces manual labor
• Handles large steel and concrete pieces for improved workflow

2.3 Urban Renovation and Emergency Rescue

The dual-cylinder hydraulic shear can quickly remove collapsed structures or damaged materials in emergency or urban renovation scenarios.

Advantages:

• 360° rotation adapts to complex environments
• High stability ensures safe rescue operations
• Speeds up debris clearance, saving critical time

3. Customer Case Studies

Case 1: Commercial Building Demolition, Berlin, Germany

Project Background:
An aging commercial building in central Berlin required demolition. The structure included reinforced concrete walls and steel beams. Traditional demolition was slow and risky.

Implementation:

• Stage 1: Demolish concrete walls for fast fragmentation
• Stage 2: Cut steel beams and columns while maintaining structural stability
• Stage 3: Sort and recycle debris for transport

Results:
The dual-cylinder hydraulic shear allowed precise cuts, avoiding damage to surrounding areas. The project completed approximately 30% faster than traditional methods, with significantly improved safety.

Customer Feedback:
“The dual-cylinder hydraulic shear performed reliably throughout demolition, saving time and enhancing safety. Its hydraulic rotation and efficient operation made our work much more reliable. We will continue to prioritize this shear for future projects.”
