# Haosail Concrete Mixer: Technical Analysis and Maintenance Manual

## I. Technical Description 

The power mechanism of Haosail concrete mixer links to the transmission system via the drive shaft, driving the mixing drum. A gear ring on the drum meshes with the gear on the shaft. This design is simple and efficient. In wet weather, it outperforms the traditional roller - drum setup by preventing slippage, ensuring stable and smooth drum rotation for better mixing.

## II. Mixer Maintenance Guidelines ###

(I) Regular Checks and Cleaning

1. Clean the drum and blades thoroughly after each use to prevent concrete build - up that could harm performance and components.

2. Check lubrication points daily and top up oil to keep parts running smoothly and extend equipment life.

### (II) Mixer Power and Circuit Safety

1. Inspect cables regularly for damage, aging, or exposure. Replace faulty cables immediately to avoid electrical accidents.

2. Ensure firm electrical connections to prevent overheating and fire risks.

### (III) Key Component Checks

1. Periodically check blades, drums, motors, and bearings for wear. Early detection can prevent breakdowns.

2. Manually rotate the mixing shaft. Replace bearings if there's roughness or noise.

### (IV) Mixer Lubrication

1. Lubricate moving parts regularly to cut friction.

2. Grease the mixing shaft every shift until grease oozes from the seal.

### (V) Avoid Overloading and Long - term Use

1. Never overload the mixer to prevent motor and component damage.

2. Prolonged overloading can overheat and age parts. Plan work to avoid this.

### (VI) Mixer Safety Rules

1. Keep hands, tools, and body out of the drum while it's running.

2. After work, check fluids and seal integrity.

### (VII) Mixer Daily Maintenance

1. Keep the work area clean and dry. Lubricate lifting pulleys and ropes weekly.

2. Clear clutter around the Mixer for safety.

### (VIII) Fault Handling If the mixer makes strange noises or vibrates severely, stop it at once and call for professional repair.
