Technological breakthroughs empower industrial upgrades: Wantong Hydraulic Chrome-Plated Telescopic Cylinders Become a New Choice for Heavy Equipment

As a listed company on the Beijing Stock Exchange, Shandong Wantong Hydraulic Co., Ltd. has achieved a significant market breakthrough with its independently developed series of chrome-plated telescopic hydraulic cylinders. Renowned for their exceptional wear resistance, corrosion protection, and versatility, these products have become the preferred components in sectors such as construction machinery and mining equipment, further driving the company's rapid growth in net profit attributable to shareholders during the first half of the year.

Chromed craftsmanship builds core competitiveness.

WANTONG Hydraulics has introduced the FE front-mounted telescopic cylinder and the double-acting telescopic cylinder, both featuring precision chrome-plated piston rods with coatings boasting high hardness levels. This advanced treatment effectively shields against corrosive media and provides exceptional resistance to high-frequency friction. This innovative process delivers three core advantages: 1. Stable operation across a wide temperature range, ensuring reliable performance in diverse conditions; 2. A leak-free sealing system that guarantees seamless operation without fluid loss; 3. A multi-stage telescopic design that not only delivers ample stroke length but also maintains a compact retracted size—perfectly tailored for heavy-duty equipment operating in space-constrained environments.

"The chrome-plated coating significantly extends the service life of piston rods, substantially reducing maintenance costs in harsh operating conditions such as those found in mining and construction industries." According to the company's technical director, the product features a high-strength alloy steel base material and globally sourced sealing components, enabling it to withstand higher working pressures. It has already undergone extensive long-term testing across various equipment, including dump trucks and cranes.

Dual-line growth confirms market recognition.

Product competitiveness directly translates into market performance. In the first half of 2025, Wantong Hydraulic achieved year-on-year growth in revenue from specialized oil cylinders for dump trucks, with particularly strong gains in overseas markets. The chrome-plated telescopic cylinders, as a core component, made significant contributions. Domestically, the company's products benefited from the government's "trade-in" policy for dump trucks, enabling it to become a supplier for leading enterprises such as Sany Heavy Industry. Meanwhile, internationally, by actively participating in global trade shows and expanding its market presence, Wantong Hydraulic secured a steady increase in orders for both gas-oil springs and telescopic cylinders.

Financial data show that the company maintained a relatively high gross profit margin in the first half of the year, with R&D expenses achieving year-on-year growth. This positive "R&D-to-Market" cycle is supported by the technological expertise provided by the company's national-level postdoctoral research workstation. Recently, the company secured a new invention patent for "Heavy Vehicle Variable-Damping Oil-Gas Springs," and its chrome-plating process upgrade project was also selected as part of Shandong Province's Postdoctoral Innovation Program.

Targeting new growth areas and accelerating iterative development

Facing the wave of intelligent equipment upgrades, Wantong Hydraulics is integrating chrome-plating technology with digitalization. Currently, the company has developed an intelligent electro-hydraulic lifting system for autonomous mining vehicles, which incorporates a new-generation chrome-plated telescopic cylinder capable of achieving highly precise stroke control. Meanwhile, to meet the demands of emerging fields such as humanoid robot joints, the company is also pioneering the development of high-precision chrome-plated transmission components, further expanding its product portfolio.

Industry analysts point out that as the "domestic substitution" trend in construction machinery deepens, Wantong Hydraulics' core technological advantage—centered around its chrome-plating process—is expected to further enhance its market share in the global hydraulic components sector.
