Hydraulic Breaker Mini Jack Hammer For Construction Equipments

The hydraulic pickaxe (mini jack hammer) is designed for construction and excavation tasks such as breaking and clearing damaged concrete, removing manhole covers, road repair, and other public works that require chipping or demolition.

Key specs: weight 20 kg (ST20S) or 26 kg (ST26S); hydraulic oil flow 26–34 lpm; working pressure 105–140 bar; impacting frequency 1500–2000 bpm. It features a V-shaped shock absorber handle and comes with commonly used hex chisel sizes.

The ST20S weighs 20 kg and measures approximately 670 × 460 mm. The ST26S weighs 26 kg and measures about 650 × 450 mm. Both models share the same hydraulic flow (26–34 lpm), pressure range (105–140 bar) and impact frequency (1500–2000 bpm).

The unit supports standard hex chisels commonly used with mini hydraulic breakers, including sizes around 1-1/4" and 1-1/8". For exact compatible shank dimensions and available chisel types, check with the supplier or parts list.

You need a hydraulic source able to deliver 26–34 liters per minute at 105–140 bar. This can be a hydraulic power pack or a carrier machine with matching flow and pressure. Ensure the power unit provides clean, cooled hydraulic oil within the manufacturer’s recommended viscosity range.

The product is designed for handheld operation, featuring a lightweight body (20–26 kg) and an ergonomic V-shaped shock absorber handle to reduce vibration. For extended work on larger carriers, check with the manufacturer for suitable mounting or adapter options.

The breaker itself is hydraulic. The description notes portability with a gas-powered engine option for the hydraulic power pack (i.e., a mobile hydraulic power unit driven by a gas engine). The breaker requires a hydraulic supply (flow and pressure) to operate.

Wear appropriate PPE (safety goggles, hearing protection, gloves, steel-toe boots). Inspect hoses and connections before use, secure the work area, never exceed specified pressure/flow, keep bystanders clear, and follow safe handling to avoid kickback. Shut down the hydraulic source before performing maintenance or changing chisels.

Daily inspections of hoses, fittings and chisel retention; keep hydraulic oil clean and at the correct level/viscosity; periodically check and replace wear parts (seals, bushings, chisels) per the manufacturer’s schedule; and lubricate/grease where specified in the manual.

Use hoses and couplings rated for the working pressure (up to 140 bar) and compatible with your hydraulic system. Use properly crimped fittings and quick couplers rated for the specified flow. If unsure, provide your supply pressure/flow to the supplier for recommended hose sizes and fittings.

Yes — common spare parts include chisels, retaining pins, seals and bushings. Contact the supplier or manufacturer (Liediao) for correct part numbers, compatible chisel types and availability.

Specific dB or vibration magnitude are not listed in the product description. Hydraulic breakers are noisy and produce significant vibration; always wear hearing protection and anti-vibration gloves. For exact figures ask the manufacturer or request a datasheet with measured values.

Yes — the breaker is suitable for concrete, asphalt and light rock typical of road repair and public works. Choose the correct chisel type (point, flat, spade) and operating pressure/technique for best results and to avoid premature wear.

Net weight is approximately 20 kg (ST20S) or 26 kg (ST26S). Packed/shipping weight and carton dimensions are not specified — request shipping details from the seller to get accurate packaged weights and freight sizing.

The product description does not list warranty or certification details. For warranty terms, safety certifications and compliance (CE, ISO, etc.), contact the seller or manufacturer before purchase.
