Used Sany 245 Excavator

Reading: 1973

It appears there might be a slight mix‑up in the query: SANY and Caterpillar are two separate, world‑leading construction equipment manufacturers. There is no “SANY 245 Caterpillar” hybrid model. You are most likely referring to the SANY SY245 — a popular 25‑tonne hydraulic excavator. Below is a comprehensive English introduction to the SANY SY245 (with the SY245H as the current flagship variant). If you intended a comparison with a Caterpillar equivalent (e.g., Cat 320 or 323), feel free to ask.

SANY SY245 Hydraulic Excavator – Detailed Introduction

Overview

The SANY SY245 (specifically the SY245H series) is a 24–25 tonne class crawler excavator designed for heavy‑duty earthmoving, trenching, quarrying, and general construction. It is part of SANY’s H‑Series, which emphasizes high efficiency, fuel economy, reinforced structures, and intelligent control. Competing directly with mid‑size excavators from Komatsu, Hitachi, and Caterpillar, the SY245 is one of SANY’s best‑selling models worldwide, trusted for its reliability, low operating costs, and advanced hydraulic performance.

Engine and Power

Engine model: Isuzu 6HK1‑XABEA‑08‑C2 (or Isuzu AR‑4HK1X on certain export variants) – a water‑cooled, 4‑stroke, direct‑injection, turbocharged and intercooled diesel engine.
Rated power: 147 kW (197 hp) @ 2,000 rpm
Peak torque: ~765 N·m @ 1,500 rpm
Displacement: 7.79 litres (6‑cylinder)
Emission standard: Meets Tier 3 / Stage IIIA (with later versions meeting Tier 4 Final / Stage V using SCR and DOC technologies).
Fuel efficiency: SANY’s proprietary positive‑flow control system and auto‑idle/speed‑sensing features reduce fuel consumption by up to 10% compared to earlier models, typically burning 14–18 litres per hour under normal digging conditions.

Hydraulic System

Type: Positive‑flow hydraulic system with Kawasaki or Rexroth main pumps and a closed‑centre control valve.
Main pumps: 2 × variable‑displacement piston pumps
Maximum total flow: 2 × 214 L/min (428 L/min combined)
Working pressure: 34.3 MPa (boom/arm/bucket) | 37.3 MPa (travel)
Auxiliary hydraulic flow: Up to 240 L/min available for attachments (breakers, grabs, tilting buckets).
Highlights: The “positive flow” architecture reduces parasitic losses by matching pump output exactly to joystick demand, giving smooth, precise multi‑function operation and excellent fuel savings. SANY’s C11 computer continuously optimises pump displacement and engine speed for maximum productivity.

Robust Structure and Undercarriage

Reinforced boom and arm: Made of high‑tensile steel with internal baffle plates. Welds are executed by robots and then inspected ultrasonically. The box‑section boom and reinforced arm are designed to withstand torsional stress during heavy lifting, digging in rock, and hammer work.
X‑frame undercarriage: Provides superior resistance to twisting and impact. Track frames are press‑formed for high rigidity.
Track shoes: Triple‑grouser steel shoes (600 mm or 800 mm width options).
Track rollers: 9 bottom rollers per side, sealed and lubricated for life.
Swing bearing: Single‑row, shear‑ball type, induction‑hardened for long life.

Operator Comfort and Safety

Cab: Large, 10‑mm thick polycarbonate windows, pressurised against dust (ROPS/FOPS certified). Air‑suspension seat with heating and multi‑adjustable armrests.
Noise level: Inside cab ~70 dB(A) – among the quietest in its class.
Climate control: Automatic air conditioning with 360° adjustable vents.
Visibility: Slim cab pillars, large skylight with sunshade, and an optional rear‑view camera with 7‑inch LCD display.
Controls: Short‑throw joysticks with proportional auxiliary control, jog dial for quick menu navigation, and a one‑touch engine deceleration button.
Safety features: Emergency stop switch, travel alarm, falling‑object guard brackets, and a sturdy guardrail around the upper structure.

Smart Technology & Maintenance

SANY SYMC (SANY Machine Control): Integrated 7‑inch colour monitor showing real‑time fuel consumption, maintenance intervals, fault codes, and attachment settings. The system supports multiple languages.
Telematics: Standard GPS/GPRS remote monitoring (SANY Cloud) allows fleet managers to track machine location, hours, fuel level, and service alerts from any web browser.
Easy maintenance:
- Ground‑level access to engine oil, fuel filters, water separator, and hydraulic oil filter.
- Side‑by‑side radiator, intercooler, and hydraulic oil cooler for easy cleaning.
- Centralised grease points on boom foot and arm.
- Reversible electric cooling fan (auto‑reverse cycle keeps radiator clear of debris).
Service intervals: Engine oil change at 500 h; hydraulic oil at 2,000 h (with high‑quality filtration).

Rippers, grapples, tilt‑rotators
Long‑reach front equipment (optional)
Quick couplers (mechanical or hydraulic)

A dedicated breaker/shear mode is selectable on the monitor, which adjusts pump flow and pressure to match the attachment.

Typical Applications

General construction: Site preparation, foundation digging, trenching for utilities.
Road & infrastructure: Slope cutting, ditch cleaning, loading trucks.
Quarry & mining support: Secondary breaking, loading blasted rock, stockpile management.
Demolition: With high‑reach front and protective guarding (available as factory option).
