uxuan 42m & 48m Concrete Pump Truck - Technical Specifications

Product Overview: Yuxuan 42m & 48m Concrete Pump Trucks

This document provides detailed technical specifications for Yuxuan's high-performance concrete pump trucks, specifically focusing on models with extended boom lengths: the JH5043 (42m) and the JH5047 (48m). These models are designed for large-scale construction projects requiring significant reach and high-volume concrete placement. The data is presented alongside the smaller JH5038 (37.9m) model for comparative context.

Core Specifications & Chassis Details

The pump trucks are built on robust, multi-axle chassis compliant with Euro VI emission standards. Key chassis and dimensional data are as follows:

Category	Item	JH5043 (42m Model)	JH5047 (48m Model)
Chassis	Chassis Brand	FOTON	SITRAK
	Engine Horsepower	470 HP	460 HP
	Overall Vehicle Length (mm)	12,167	11,910
	Overall Vehicle Weight (t)	32 (Four-axle)	34.5 (Four-axle)
	Superstructure Weight (approx. tons)	21	23

Boom System & Reach Capabilities

The boom system is the critical component defining the pump's placement capabilities. The 42m and 48m models feature advanced multi-section booms with extensive reach.

Boom System Parameter	JH5043 (42m)	JH5047 (48m)
Maximum Vertical Boom Height (m)	42.8	46.3
Horizontal Placing Radius (m)	38.5	41.3
Placing Depth (m)	29.3	32.3
Number of Boom Sections / Rotation	5 sections (90°/180°/235°/180°/245°)	6 sections (90°/180°/180°/235°/180°/110°)
Boom Control Mode	Fixed displacement pump	Electrically proportional control variable displacement pump
Turret Rotation Angle	470°

The 48m model (JH5047) stands out with its 6-section boom and more advanced electrically proportional control system, allowing for smoother, more precise boom movements compared to the fixed displacement system on the 42m model.

Pumping System Performance

These pump trucks are engineered for high-output concrete placement, capable of handling standard concrete mixes with high efficiency.

Pumping System Parameter	JH5043 (42m)	JH5047 (48m)
Theoretical Max. Pumping Capacity (m³/h)	134	169 / 114 (Dual Mode)
Max. Concrete Outlet Pressure (MPa)	6.2	7.9 / 11.7
Conveying Cylinder (Inner Diameter x Stroke mm)	260 x 1650	230 x 1900
Theoretical Max. Pumping Cycles	25.5 /min	36 / 24 /min
Concrete Delivery Pipe Diameter (mm)	125
Pumpable Concrete Slump (mm)	160 - 220
Maximum Aggregate Size (mm)	40

The JH5047 (48m) offers a dual-mode pumping capacity (169/114 m³/h), providing flexibility between ultra-high volume and high-pressure output (up to 11.7 MPa), making it suitable for the most demanding high-rise or long-distance pumping applications.

Hydraulic, Electrical & Support Systems

Hydraulic System: Both models use an open hydraulic system operating at 31.5 MPa. Key components include main hydraulic pumps from Push/Rexroth and high-quality valves from brands like HAWE/Norma.
Control System: Operation is facilitated via a wireless remote control (HBC/OHM or Techwell/OUM brands). The electrical systems are powered by the chassis (24V) and utilize controller modules with components from Siemens or Schneider.
Stability System: Both models feature an X-R type outrigger deployment system with wide spans (front/rear approximately 8.6m/9.3m for 42m and 8.7m/9.7m for 48m) to ensure solid stability during operation.
Cleaning & Maintenance: Systems include centralized lubrication, high-pressure water pumps for cleaning, and air-cooled hydraulic oil tanks (~400-475L volume).

Summary and Application

The Yuxuan JH5043 (42m) and JH5047 (48m) concrete pump trucks represent the high-end of mobile concrete placement technology. The 42m model is a powerful, reliable workhorse for large commercial and infrastructure projects. The 48m model, with its greater reach, advanced proportional boom control, and dual-mode high-output/high-pressure pumping system, is engineered for flagship projects such as skyscrapers, large bridges, and expansive industrial facilities where maximum reach and output are critical. The use of reputable international component brands (Rexroth, Siemens, Parker, etc.) throughout the hydraulic and control systems underscores a commitment to reliability and performance.
