Product Description

Coal Mine Machine Hydraulic Support Jack Hydraulic Cylinder for Mining Transportation

Product Feature
 

Coal mining equipment cylinder has a wide range of applications. Ever Power company has been deeply involved in the field of mining equipment for 15 years, with deep technical expertise and process accumulation, and has achieved full coverage of hydraulic cylinder products for "three machines and one support" equipment (coal shearer, roadheader, scraper conveyor, hydraulic support). Especially in the field of hydraulic supports, as an important supporting and executing component, the stability of product quality is crucial. Over the years, our company has become a major cylinder supplier for domestic large main machine manufacturers such as Coal Mining Machinery, Yankuang Donghua Heavy Industry, and PMJ, relying on its excellent product quality and high-quality service.

Product Advantages

• The hydraulic support column connects the support's top beam to the base, bearing the load of the top plate and serving as the support's primary load-bearing component. It primarily consists of an outer cylinder, a middle cylinder, a plunger, a guide sleeve, a bottom valve, and seals. The system utilizes an anti-corrosion process using laser cladding on the outer diameter and copper molten metal on the inner bore, extending its lifespan.

• The hydraulic support's top adjustment jack is a crucial component of the hydraulic support system. Its piston rod is chrome-plated for increased resistance to corrosion, friction, and impact. The hydraulic support's top adjustment jack plays an indispensable role in industries such as mining. Its support and adjustment functions provide strong guarantees for the stability and flexibility of the hydraulic support.

• The hydraulic support's push jack is a crucial component of the hydraulic support system. Its piston rod is chrome-plated for increased resistance to corrosion, friction, and impact. Its primary function is to push the conveyor and pull the support. The push jack is located in the middle of the base. Due to the fact that the required pulling force is greater than the pushing force, the hydraulic support push jack is generally inverted, and there is also a positive differential connection form. After installing the sensor, electro-hydraulic control can be achieved;

Application

1. Hydraulic Excavators and Electric Shovels
These are the workhorses of open-pit mining. Every major movement is driven by large-bore, heavy-duty hydraulic cylinders.

Boom, arm, and bucket cylinders: These three groups of cylinders work together to control the digging and lifting movements. They provide the powerful force needed to break rock, scoop up tons of material, and lift it out of the excavation.

Quick-coupler cylinders: Smaller cylinders that allow the operator to quickly change attachments, such as switching from a bucket to a hydraulic hammer.

2. Dump Trucks
Dump trucks are the primary tool for transporting materials within the mine. Their most critical hydraulic component is the dump cylinder.

Lift Cylinders: These are typically large, multi-stage telescopic cylinders. When activated, they extend to raise the massive dump bucket, allowing tons of ore or overburden to be quickly and efficiently unloaded to a crusher or scrap yard.

Suspension Cylinders: Many large dump trucks use a hydraulic suspension system (hydro-pneumatic struts), which acts as both shock absorbers and structural support, providing a stable ride even under extreme loads.

Steering Cylinders: Provide steering power to the truck's large front wheels.

3. Bulldozers
Bulldozers are used for clearing, grading, and moving soil.

Blade Lift Cylinders: Two large cylinders on each side of the bulldozer raise and lower the main blade.

Blade Tilt/Angle Cylinders: One or two cylinders tilt the blade forward and backward or left and right, allowing for precise material control and grading.

Ripper Cylinders: Large cylinders at the rear of the bulldozer control the ripper, a claw-like device used to break up hard ground or rock.

4. Wheel Loaders
Wheel loaders are essential for loading dump trucks and transporting materials around the site.

Lift Arm Cylinders: These cylinders raise and lower the main loading arm, which lifts the bucket from the ground to the height of the dump truck.

Bucket Tilt Cylinder: Controls the bucket's tilting or "curling" motion, which is crucial for efficient scooping and accurate dumping.

5. Drill Rig
Drill rigs are used to drill holes for explosives.

Drill Rod and Feed Cylinder: Cylinders are used to lift and position the drill rod. The long-stroke "feed cylinder" provides downward force (pull-down force) on the drill string, forcing the drill bit into the rock.

Leveling Jack: Hydraulic cylinders act as jacks, stabilizing and leveling the entire drill rig on uneven ground, ensuring accurate and safe drilling operations.

6. Underground Mining Equipment
In underground mines, specialized hydraulic equipment is crucial to safety and production.

Longwall Roof Supports: These are massive, shield-like structures lined with powerful hydraulic cylinders (pillars). They hold down the mine roof, preventing it from collapsing during coal or ore extraction, and propel the mining machine forward.

Crusher/Hydraulic Hammer: These attachments are typically mounted on excavators or specialized transport vehicles and use hydraulic cylinders to drive a powerful impact mechanism to break up oversized boulders.
