• Outrigger layout: Telescopic widened front and rear outriggers featuring stable support and outstanding anti-overturning performance

Pumping System

• Theoretical maximum concrete displacement: 140~160m³/h
• Maximum system working pressure: 85MPa, delivering strong pumping force suitable for high-grade concrete and large aggregate concrete
• Equipped with original S-tube reversing structure, brand-new spectacle plate, cutting ring, concrete piston and mixing assembly to effectively prevent pipe blockage
• Adopts wired + wireless dual remote control system with precise and sensitive operation and smooth boom movement

3. Detailed Configuration of Mercedes-Benz Actros 4141 Chassis

• Drive form: 8×4 four-axle heavy-duty chassis (four front wheels & eight rear wheels), total mass 41 tons, specially calibrated for heavy-load operation of pump trucks
• Powertrain: Mercedes-Benz OM501LA V6 diesel engine, rated 408 horsepower with peak torque of 2000N·m, featuring sufficient power output and stable fuel consumption, suitable for long-distance transit between construction sites
• Transmission: Mercedes-Benz G210-16 16-speed manual transmission with reliable shifting and strong climbing capacity under heavy load
• Braking & safety: Original Telligent intelligent braking system equipped with ABS/ASR anti-lock and anti-slip functions for high driving safety
• Cab configuration: Air-spring shock-absorbing seat, sealed air conditioning and complete instrument assembly, delivering comfortable driving experience and reducing fatigue during long-hour operation
• Fuel tank capacity: Large 300L fuel tank to reduce frequent refueling and improve transit efficiency
• Overall dimensions: Approx. 11.98m (L) × 2.5m (W) × 3.97m (H), moderate turning radius and high maneuverability for access to urban construction sites

4. Standard Whole-Vehicle Remanufacturing Process (Core Advantage vs Ordinary Used Trucks)

1. Complete full disassembly: The chassis, boom, pumping hydraulic system and electrical wiring are fully disassembled into individual parts for comprehensive rust removal, high-pressure cleaning and degreasing, followed by one-by-one flaw detection and screening.
2. Flaw detection and repair for structural components: Ultrasonic inspection is conducted on the boom, main support base, outriggers and hopper. Cracked positions are groove-welded for reinforcement with stress relief treatment, and deformed parts are corrected to eliminate potential fracture risks in later service.
3. In-depth remanufacturing of hydraulic system: Main hydraulic pump, multi-way valve, boom cylinders and swing cylinders are completely disassembled for overhaul; worn components are replaced. All oil seals, hydraulic hoses and filter elements are renewed. The whole machine undergoes pressure holding testing to eliminate oil seepage, oil leakage and insufficient movement power.
4. Overhaul of chassis system: The engine is disassembled and inspected, with cylinder kit replaced as required. The full vehicle transmission and axles are maintained and inspected; wearing parts including brake pads, tires and suspension components are renewed. The braking system is comprehensively calibrated and passes road test verification.
5. Upgrade of full-vehicle electrical system: The entire wiring harness is rearranged and replaced; controllers, sensors and remote control system are inspected and commissioned with neat wiring layout to avoid short circuit and signal failure faults.
6. Assembly and commissioning of whole machine: Assembled in accordance with original factory torque specifications; including no-load movement debugging, full-load pumping pressure test, full-stroke reciprocating test of boom and pressure bearing test for outriggers.
7. Surface finishing and painting: The whole vehicle is sandblasted for rust removal, coated with epoxy primer plus original topcoat with complete logos and tidy appearance.
8. Final factory inspection: A complete vehicle inspection record is issued; the unit is warehoused only after all parameters meet new-machine standards.

5. Core Product Advantages

1. High cost performance: Its selling price is far lower than that of brand-new original pump trucks, while its remanufactured quality greatly exceeds ordinary second-hand pump trucks for faster investment payback cycle.
2. Stable and reliable quality: Key hydraulic and structural parts are repaired after flaw detection with low failure rate and high attendance rate, adapting to high-intensity continuous construction work.
3. Strong versatility: Sufficient spare parts available in the market for convenient later maintenance and lower maintenance costs.
4. Wide working condition adaptability: The mainstream 46-meter boom height balances construction needs of high-rise buildings and narrow municipal sites with flexible transit performance, applicable to engineering projects at home and overseas.
5. Flexible transaction mode: Physical vehicle inspection and pumping test are available for in-stock trucks; customized remanufactured pump trucks are also acceptable. The whole vehicle is shipped in bulk without packaging, with bulk carrier export solutions supported.
