Demolition contractors and scrap yards across Thailand face growing pressure to process steel structures, rebar, and mixed metal waste faster. Torch cutting is slow, dangerous, and produces toxic fumes. Crushing with buckets leaves tangled rebar that cannot be sold. Manual sorting wastes labor and creates safety hazards. Many Thai demolition companies need an attachment that cuts steel cleanly and separates material in one pass. YG Machinery’s excavator demolition shear solves these problems with hydraulic jaws that deliver up to 387 tons of shear force. The YG-620 to YG-4052 models fit carriers from 5 to 50 tons. These excavator scrap shear units have gained strong interest across Thailand’s demolition and recycling sectors.

Case Study One: Thailand – High-Rise Demolition Project
Client Background
A Thai demolition contractor secured a contract to dismantle a 12-story reinforced concrete building in Bangkok. The project required cutting structural steel beams, rebar cages, and mixed metal debris. The contractor operates a fleet of 20-ton and 30-ton excavators.
Client Challenge
The contractor used torch cutting for steel removal. Torch work required gas cylinders, fire watch, and permits. Cutting speed averaged 15 minutes per beam. The project timeline allowed only 8 weeks for structural steel removal. The client also needed to separate rebar from concrete for recycling.
YG Solution
YG supplied the YG-2200 excavator demolition shear with 2200kg weight and 171.2T bottom shear force. The 500mm max open size handles large beam sections. The 360 hydraulic rotation allows precise positioning in tight spaces. The 320bar working pressure delivers consistent cutting force. The shear mounts to the contractor’s 20-25 ton excavators. YG provided mounting pins and hydraulic hose kits matched to the client’s machine models.
Client Feedback and Results
“The YG-2200 cuts through steel beams in 30 seconds instead of 15 minutes with torches. We eliminated gas cylinder handling and fire watch costs. The 360 rotation lets us reach rebar inside concrete columns.” The project manager confirmed the shear completed steel removal 4 weeks ahead of schedule. The contractor ordered two additional units for other Bangkok projects.

Case Study Two: Oman – Scrap Yard Metal Processing
Client Background
An Omani scrap yard processes structural steel, rebar, and mixed metal waste from construction sites. The yard handles 500 tons monthly and sells processed scrap to steel mills. Their existing equipment could not cut thick beams or separate tangled rebar efficiently.
Client Challenge
The yard needed a metal shear for excavator that could cut steel beams up to 30mm thick and rebar bundles up to 500mm diameter. Torch cutting was too slow for their volume. A stationary shear required material transport to the processing area, adding handling costs. The client wanted a mobile attachment that could process material where it sits.
YG Solution
YG recommended the YG-2977 excavator demolition shear with 2977kg weight and 330.2T bottom shear force. The 660mm max open size and 578mm effective shear depth handle thick beams and rebar bundles. The 360 hydraulic rotation allows the operator to position material for optimal cutting angle. The shear mounts to the yard’s 28-35 ton excavator. The 320bar pressure delivers consistent force across the full jaw length.
Client Feedback and Results
“The YG-2977 cuts 30mm steel beams in a single pass. We reduced processing time from 3 days to 1 day per 50-ton load. The mobile attachment eliminates material handling costs.” The yard manager confirmed the excavator scrap shear increased monthly throughput by 40%. The yard plans to add a second shear for their new processing line.

Frequently Asked Questions
Q: How do I choose the right excavator demolition shear for my machine?
Match the shear model to your carrier weight. The YG-620 fits 5-9 ton excavators. The YG-4052 fits 38-50 ton machines. YG provides mounting pin dimensions and hydraulic flow requirements for your specific excavator model.
Q: What materials can the excavator scrap shear cut?
The shear handles structural steel, rebar, pipe, channel, angle iron, and mixed metal debris. It cuts steel beams up to the effective shear depth rating for each model.
Q: Does the shear require a rotating circuit on my excavator?
The YG-620 uses 360 collision rotation, which works without an auxiliary hydraulic circuit. The YG-1413 through YG-4052 models use 360 hydraulic rotation, requiring a bidirectional auxiliary circuit on the excavator.
Q: How often does the shear need blade maintenance?
Inspect blades every 200 operating hours. Rotate or replace blades when the cutting edge wears beyond specification. YG supplies replacement blades and offers regrinding services.
Q: What hydraulic pressure does the shear require?
Working pressure ranges from 235bar on the YG-620 to 320bar on larger models. YG provides hydraulic hose kits and pressure relief valves matched to your excavator’s specifications.
