Hydraulic Oil Tank Selection Guide For Concrete Mixer Trucks

 

I. Importance of Hydraulic Oil Tanks in Mixer Trucks

The hydraulic oil tank is one of the core components in a concrete mixer truck's hydraulic system, with main functions including:

· Storing hydraulic oil

· Cooling and dissipating heat from hydraulic oil

· Settling contaminants

· Separating air and moisture from the oil

Selecting the appropriate tank capacity is crucial for ensuring stable operation of the hydraulic system and extending component service life.

II. Matching Principles Between Mixer Capacity and Hydraulic Tank

1. Basic Matching Principles

Mixer Truck Capacity (m³)	Minimum Recommended Tank Capacity (L)	Recommended Capacity Range (L)
3-6	18	18-26
8-10	20	20-26
12-14	26	26-32
16-18	32	32-36
20+	36	36-36+

2. Considerations

· Duty cycle: Frequent start-stop operations require larger tank capacity for better heat dissipation

· Ambient temperature: High-temperature environments demand larger tank capacity

· Hydraulic system power: High-power systems need larger tanks

· Space constraints: Consider available installation space on the vehicle

III. Detailed Selection Guide

1. Small Mixer Trucks (3-6m³)

· Typical tank capacity: 18-26L

· Features:

  - Compact design

  - Often use aluminum tanks to reduce weight

  - Basic cooling design sufficient for requirements

2. Medium Mixer Trucks (8-14m³)

· Typical tank capacity: 20-26L

· Features:

  - Require better cooling performance

  - Recommended to equip oil temperature monitoring devices

  - May need auxiliary cooling devices (fan cooling)

3. Large Mixer Trucks (16m³ and above)

· Typical tank capacity: 32-36L

· Features:

  - Must have high-efficiency cooling systems

  - Recommend using stainless steel for better durability

  - Require multiple monitoring (oil level, temperature, etc.)

  - May need independent cooling systems
