2025-04-30

Deep in the mines, every precise movement of hydraulic supports and tunneling machines relies on the powerful drive of energy mining equipment cylinders. The cylinders from Shandong Wantong Hydraulic Co., Ltd. (hereinafter referred to as “Wantong Hydraulic”), with their labels of “wear-resistant, pressure-resistant, and durable”, are becoming a “hidden champion” in China’s mining machinery field.

Deep in the mines, every precise movement of hydraulic supports and roadheaders relies on the powerful drive of energy mining equipment cylinders. The cylinders from Shandong Wantong Hydraulic Co., Ltd. (hereinafter referred to as “ Wantong Hydraulic ” ”) are becoming “ durable, pressure-resistant, and robust ” with the label, becoming a “ hidden champion ”。

Technological Breakthrough: From “ Usable ” to “ Robust ”

Energy mining equipment faces extreme operating conditions: hydraulic supports must withstand coal mine rock bursts, and roadheaders must operate continuously in high-dust, high-humidity environments. Traditional cylinders are prone to wear and tear and have short lifespans, becoming an industry pain point. Wantong Hydraulic's response strategy is very “ hardcore ”——

• Laser cladding + copper melting process : A wear-resistant and anti-corrosion layer is “ plated ” on the surface of the hydraulic support columns and piston rods, increasing lifespan by 30% more than.

• Pure water hydraulic cylinder : Responding to the needs of green mining, pure water replaces traditional hydraulic oil, directly enhancing sealing and corrosion resistance, solving the “ conflicting ” problems of environmental protection and performance.

• Energy-absorbing core column : Specifically designed to handle roof collapse and rock bursts in coal mines, these “ severe operating conditions ” resolve extreme impact forces through controllable deformation and energy dissipation technology, transforming them into “ easily manageable forces ” .

“ Previously, cylinders needed to be replaced on average every 3 month, but now, using Wantong products, they can last more than half a year. ” Feedback from a coal mine equipment administrator in Shanxi.

Scenario Breakthrough: From Mines to the Deep Sea

Wantong Hydraulic's energy mining cylinders have already gone beyond traditional coal mine scenarios:

• 1000-ton hydraulic support : Matched with Zhengzhou Coal Machinery's intelligent electro-hydraulic control system, the dimensional and positional tolerance accuracy reaches the micrometer level, allowing “ steel behemoths ” to also perform “ a mechanical ballet ”。

• Combined excavation, support, and bolting machine : In Shaanxi Coal Group's intelligent mines, equipment equipped with Wantong cylinders has achieved excavation, support, and anchoring “ in one ” step, significantly improving efficiency 40%。

• Deep-sea mining test ：2024 In the year, Wantong Hydraulic customized a high-pressure resistant cylinder for a deep-sea mining equipment, successfully completing a pressure test at 500 meters underwater, opening up “ new avenues for deep-sea mining ” .
