Boom Cylinder for Concrete Pump Truck

Product Overview

Boom Cylinder for Concrete Pump Truck is a heavy‑duty double‑acting Hydraulic Cylinder. As the core executive component of concrete pump truck hydraulic system, this Hydraulic Cylinder drives lifting, folding and luffing movements of multi‑section boom for construction Machine. It bears huge alternating load and frequent impact during high‑altitude concrete pouring operation. Equipped with integrated balance valve interface, it keeps boom stable under variable load conditions. Widely used for original equipment assembly, equipment overhaul and aftermarket spare‑parts replacement of concrete pump truck Machine.

Working Principle

High‑pressure hydraulic oil output from hydraulic system enters the rod‑less chamber and rod chamber of this Hydraulic Cylinder. Controlled by main hydraulic valve and matching balance valve, the piston rod extends or retracts, realizing upward luffing, descending and folding actions for pump‑truck boom. The balance valve locks oil circuit to prevent boom slipping under heavy load. As key driving component of construction Machine, this Hydraulic Cylinder transfers hydraulic energy into powerful mechanical thrust, ensuring safe and accurate positioning of boom during concrete pouring, and protecting the whole hydraulic system from overload risk.

Core Advantages

1. Heavy‑duty optimized structure, specially designed for alternating heavy‑load working condition of pump‑truck boom, excellent anti‑fatigue performance for long‑term continuous operation of Machine.

2. High‑precision alloy barrel and hard‑chrome‑plated piston‑rod, good wear‑resistance and corrosion‑resistance, greatly extend service life of the Hydraulic Cylinder.

3. Premium sealing combination effectively reduces internal and external leakage, maintains stable pressure‑holding performance of hydraulic system.

4. Built‑in buffer structure reduces impact at stroke end, lowers vibration stress for boom and whole Machine.

5. Standard installation dimensions and connection ports, easy for on‑site disassembly, maintenance and spare‑parts replacement.
