A Malaysian demolition contractor contacted YG Machinery in early 2026 after facing difficulties with large-scale steel structure dismantling projects. The company mainly worked on factory renovation, scrap recycling, and old building demolition. Their existing cutting tools could not maintain stable performance when processing thick steel beams and reinforced structures.
The contractor searched for a hydraulic shear attachment for excavator that could match their 30-ton excavator and improve daily cutting efficiency. Their main requirements were clear. The attachment needed strong crushing force, reliable hydraulic performance, easy installation, and low maintenance requirements.
After the first inquiry, YG engineers communicated with the customer about excavator specifications, hydraulic flow, working pressure, and the type of materials being processed. After several technical discussions and a video meeting, the customer selected the YG310R hydraulic shear model for their demolition operation in Malaysia. The equipment provided a maximum opening of 565 mm, a throat depth of 630 mm, and a central crushing force of 351KN, which matched their steel cutting requirements.

Customer Requirements for Concrete Metal Shear for Excavator Applications
The customer’s main project was located in Johor, Malaysia. The site included abandoned industrial buildings and old steel workshops that required dismantling before redevelopment. Unlike simple concrete demolition, the project involved large amounts of steel structures, pipes, and reinforced components.
During the first technical communication, the customer explained several challenges:
- Existing cutting tools had low efficiency on thick steel materials.
- Manual cutting created safety risks and increased labor costs.
- Hydraulic attachments from previous suppliers required frequent maintenance.
- The demolition schedule required continuous operation for several hours every day.
The contractor needed equipment that could be installed directly on their existing excavator without major hydraulic system modifications. The engineers requested detailed information about the excavator model, operating weight, and hydraulic parameters before recommending the final configuration.
According to common excavator attachment selection practices, the carrier weight, hydraulic pressure, oil flow, material type, and production target must be considered together before choosing a suitable shear. The customer provided all necessary information, including excavator tonnage and project conditions.
After reviewing the data, YG Machinery recommended the YG310R model because it was suitable for 28–39 ton excavators with a working pressure of 35MPa. The customer confirmed that the configuration matched their demolition requirements.
Hydraulic Shear for Sale Configuration Discussion and Order Confirmation
Before placing the order, the customer requested a detailed online meeting. The purpose was not only to confirm the model but also to check installation details. During the video conference, YG engineers explained the structure, blade system, hydraulic connection points, and maintenance procedures.
Several small adjustments were made based on the customer’s working environment.
The final configuration included:
- YG310R hydraulic shear attachment.
- Excavator-mounted installation structure.
- High-strength cutting blades.
- Reinforced hydraulic cylinder system.
- Operation and maintenance documents in English.
- Additional sealing components for future maintenance.
The customer compared different suppliers before making the final decision. Their main consideration was not only the purchase price. They focused more on service life, cutting force, and compatibility with their excavator.
After receiving the final technical drawing and quotation, the customer completed the payment, and YG Machinery started production. The entire process from inquiry to order confirmation took around two weeks because both teams completed technical communication efficiently.

Production Process and Quality Inspection Before Shipment
Production started immediately after payment confirmation. The manufacturing team arranged material preparation, welding, machining, hydraulic cylinder assembly, and final testing according to the approved specifications.
The hydraulic shear structure required high-strength materials because demolition work creates continuous impact and pressure during operation. Each major component was inspected before assembly.
The quality inspection process included:
- Checking overall dimensions.
- Testing hydraulic cylinder movement.
- Inspecting blade installation accuracy.
- Confirming maximum opening distance.
- Checking surface treatment quality.
- Testing attachment connection points.
Before shipment, YG Machinery recorded operation videos and sent inspection photos to the customer. The customer reviewed the test results remotely and confirmed that the equipment could be shipped.
The final machine matched the technical requirements:
- Working pressure: 35MPa.
- Maximum opening: 565mm.
- Overall weight: 3300KG.
- Front-end crushing force: 135T.
- Central crushing force: 351KN.
These specifications allow the attachment to handle steel cutting tasks in industrial demolition environments.
YG Metal Shear for Excavator Export Packaging and Transportation to Malaysia
After the final inspection was completed, the hydraulic shear was prepared for international shipment. The attachment was protected with anti-rust treatment on key metal surfaces. The hydraulic ports were sealed to prevent dust and moisture from entering during transportation.
YG Machinery arranged professional export packaging based on the size and weight of the equipment. The main body was fixed inside a strong wooden frame. Additional protection was added around the blade area and connection points.
The machine was shipped from China to Malaysia by sea. The customer received tracking information after loading. During transportation, both teams maintained communication regarding customs documents, arrival schedules, and unloading preparation.
After the equipment arrived at the Malaysian port, the customer arranged local transportation to move it to the demolition site. The complete delivery process was completed smoothly without damage during transit.

Steel Structure Demolition Equipment Installation and First Operation
After receiving the attachment, the customer connected it to their excavator according to the installation instructions provided by YG engineers. The hydraulic connection points were checked before the first operation.
During the first startup, the operator tested several functions:
- Opening and closing movement.
- Hydraulic response speed.
- Blade cutting performance.
- Excavator balance during operation.
- Noise and vibration conditions.
YG engineers joined an online training session with the customer’s operators. The training covered daily inspection points, lubrication requirements, blade maintenance, and safe operating methods.
The engineers also explained that correct operation habits directly affect attachment service life. Operators should avoid unnecessary impact loading and should select suitable cutting positions according to different steel materials.
The first practical test was carried out on old steel frames from an abandoned factory building. The attachment successfully cut through structural steel components and separated large sections into smaller pieces for transportation and recycling.
The customer recorded the first working day and shared operation videos with YG Machinery. The feedback showed that the equipment matched the excavator well and provided stable performance during continuous demolition work.
Performance Feedback After Malaysia Demolition Projects
After several months of operation, the customer provided feedback based on actual project data. The attachment had been used for factory demolition, steel recycling, and structural dismantling tasks.
Compared with their previous cutting equipment, the customer reported several improvements:
- Faster steel separation during demolition.
- Reduced dependence on manual cutting tools.
- Lower labor requirements on site.
- Better control when processing different steel structures.
- More convenient transportation because the attachment worked directly with their excavator.
The contractor mainly used the machine for steel beams, metal frames, pipes, and other construction materials. The stable hydraulic system helped maintain consistent working performance throughout daily projects.
The customer also mentioned that selecting the correct excavator attachment model was important. The YG310R matched their excavator size and provided enough cutting force without overloading the carrier machine.
This project showed how a suitable hydraulic attachment can improve demolition workflow. Instead of changing the whole working method, the contractor upgraded existing excavator capability with a specialized tool.
