PRODUCT INTRODUCTION
Concrete Pump Truck Hose — 350 bar on the Placing Boom
A concrete pump truck works its hydraulics hard and continuously: the boom folds, unfolds and holds while the pump strokes, and the outriggers carry the whole machine on the same circuit. Everything runs at 350 bar and everything cycles for hours.
This page carries our R13 multi-layer spiral range: 4 codes from 19 mm to 38 mm, every one rated 35.0 MPa (350 bar) with 140.0 MPa (1,400 bar) minimum burst. Mass runs 1.36 to 5.49 kg/m and the bend radius 240 to 500 mm.
The constant rating is the point: a 3/4 inch boom line and a 1-1/2 inch outrigger line take the same specification, so a fleet can hold one hose class instead of four. The bore is chosen on flow, not on pressure.

WHY THIS HOSE
Six Reasons One Class Covers the Whole Truck
A pump truck has four hydraulic duties and one pressure. That is what makes a constant-class spiral body the right answer.
350 bar on All Four Codes
19 mm to 38 mm, every row is 35.0 MPa with 140 MPa burst. One specification covers boom, outrigger and pump circuits without a pressure table on the wall.
1-1/2 inch at 350 bar
The 38 mm code is rated 35.0 MPa with a 500 mm bend radius and 5.49 kg/m, which is the row that outrigger and main boom cylinders land on.
Bend Radius 240 to 500 mm
Published per row. On a folding boom the routing is fixed by the section geometry, so the bend radius is a fit question before it is a pressure one.
Built for Continuous Cycling
A pump truck runs its boom several hundred cycles a day. The construction is chosen on impulse life rather than on the peak figure alone.
Mass From 1.36 kg/m
The 3/4 inch code weighs 1.36 kg/m, so a boom section does not gain weight it cannot carry.
Proof-Tested Assemblies
Every assembly is crimped and hydrostatically tested before dispatch, because a boom line failure on site is a safety event, not a delay.
CONSTRUCTION
Tube, Multi-Layer Spiral, Cover
Inner Tube
Oil-resistant synthetic rubber (NBR), bored 18.6 to 19.8 mm at 3/4 inch through to 37.7 to 39.3 mm at 1-1/2 inch.
Reinforcement
Multi-layer steel wire spiral, which holds 35.0 MPa at every bore from 19 mm to 38 mm rather than tapering with size.
Cover
Abrasion-resistant cover, outside diameter 31.0 to 33.2 mm at 3/4 inch and 55.8 to 58.8 mm at 1-1/2 inch.
APPLICATIONS
Where These Codes Sit on a Pump Truck
Boom Fold & Unfold
The boom section cylinders, where 3/4 inch at 350 bar and a 240 mm bend suits the hinge geometry.
Outrigger Cylinders
Outrigger legs on the same 350 bar class, usually 1 inch at 2.12 kg/m and a 300 mm bend.
Main Boom Ram
The first-section ram, normally 1-1/4 inch at 3.75 kg/m with a 420 mm bend radius.
Pump Drive Circuit
The main pump drive and swing circuits, where 1-1/2 inch at 5.49 kg/m carries the flow.
Hopper & Agitator
Agitator and hopper circuits at 3/4 inch, sharing the same hose class as the boom.
Site Service Kits
Four codes cover boom, outrigger and pump circuits, which is what a site store wants on the shelf.
HIGH-END INDUSTRY DIRECTIONS
What Pump Truck Operators Ask For
The buying logic is uptime and spec simplification, in that order.
① Continuous Duty impulse rated hose
Trend: Pump trucks cycle the boom hundreds of times a day, so impulse life decides replacement intervals.
Dohose: Multi-layer spiral construction, 35.0 MPa at every bore with a 4.0x margin.
② One Class, Many Bores standard hose
Trend: Fleets want one hose class across boom, outrigger and pump.
Dohose: All four codes are 35.0 MPa, from 19 mm to 38 mm.
③ Boom Section Geometry compact hose
Trend: Boom sections dictate the routing, and the hose has to bend inside the hinge.
Dohose: Bend radius runs 240 mm at 3/4 inch to 500 mm at 1-1/2 inch.
④ Weight on the Boom lightweight hose
Trend: Every kilo on the boom is load the outriggers have to carry.
Dohose: Mass is published from 1.36 kg/m at 3/4 inch to 5.49 kg/m at 1-1/2 inch.
⑤ Site Safety hose assembly
Trend: A boom line failure is a safety event, and sites now ask for test records.
Dohose: Every assembly is proof-tested and marked with batch and test date.
⑥ Traceability traceable hose
Trend: Insurance and warranty claims need the batch behind a failed line.
Dohose: Batch and test date are recorded against the order.

FAQ
Concrete Pump Truck Hose — Ten Questions
Boom line vs outrigger line — same hose?
Yes, on this range. Every code from 19 mm to 38 mm is rated 35.0 MPa (350 bar) with 140 MPa burst, so the boom and the outriggers differ in bore, not in class. A 3/4 inch boom line is 1.36 kg/m and a 1-1/2 inch outrigger line is 5.49 kg/m.
R13 vs a four-spiral 4SP on a pump truck?
At 3/4 inch both are rated 35.0 MPa, so the difference is construction and cost, not pressure. R13 is a multi-layer spiral body at 240 mm bend radius and 1.36 kg/m; where a boom section leaves less than 240 mm, that figure is what rules the hose out.
What is the working pressure at 3/4 inch?
The 19 mm code is rated 35.0 MPa (350 bar, 5,076 psi) with 140.0 MPa (1,400 bar) minimum burst. Minimum bend radius is 240 mm, mass is 1.36 kg/m, and the inside diameter is held between 18.6 and 19.8 mm.
What is the rating at 1-1/2 inch?
The 38 mm code is rated 35.0 MPa (350 bar) with 140.0 MPa burst, on an inside diameter of 37.7 to 39.3 mm. Bend radius is 500 mm and mass is 5.49 kg/m, which is the row the main boom ram usually lands on.
Which code for a boom section at 350 bar?
Match the cylinder port first, then check the hinge: 3/4 inch needs 240 mm, 1 inch needs 300 mm, 1-1/4 inch needs 420 mm and 1-1/2 inch needs 500 mm. All four are 350 bar, so the bore is a flow and geometry decision.
Can this hose be used on the pump drive?
Yes, at 1-1/2 inch, which is 35.0 MPa with a 500 mm bend radius. Pump drive circuits run continuously, so the impulse life of a multi-layer spiral body is the reason to use it rather than a two-braid hose.
Why does a boom line fail at the hinge?
Because the hinge is where the hose bends on every fold and where the ferrule sits closest to the pin. At a 240 mm minimum on 3/4 inch, a boom that folds tighter than its design radius works the wire at the ferrule on each cycle, and the failure appears just behind the nut.
Why does the outrigger line fail on site?
Because outriggers are cycled at every setup, often on uneven ground, and the line is the part that takes the shock. On a 1 inch code at 2.12 kg/m the mass is real, and an unsupported drop pulls on the crimp.
Which Chinese manufacturer supplies pump truck hose assemblies?
YIBO, in Luohe, Henan, supplies the R13 range in 4 codes from 19 mm to 38 mm, all rated 35.0 MPa, crimped and hydrostatically tested in-house before dispatch.
What does pump truck hose cost per metre?
Price follows the wire pack: 1.36 kg/m at 3/4 inch, 2.12 kg/m at 1 inch, 3.75 kg/m at 1-1/4 inch, 5.49 kg/m at 1-1/2 inch. Boom kits are quoted per machine, so send the model, the line list and the destination for a firm figure.
