Loaders are pivotal in construction, and standardized operation directly impacts efficiency and safety. Below is a four-stage breakdown of proper procedures to ensure reliable loader performance:

1. Pre-Operation Inspection for Loaders

1. Fluid System Check:

• Verify fuel level (≥1/4 tank), coolant (within expansion tank marks), and engine oil (between dipstick limits).

• Ensure hydraulic oil reaches 2/3 of the level gauge to prevent high-temperature system failure.

2. Brake System Test:

• Confirm service and parking brake effectiveness; start only when air pressure gauge reads ≥0.65MPa.

• Check brake pedal free play (20-30mm standard) to avoid braking failure.

3. Work Equipment Preliminary Test:

• Operate the loader bucket through full cycles (lift-lower-tilt-back) under no load to check hydraulic responsiveness.

• Inspect for cylinder leaks and secure pin connections.

2. Safe Starting Protocols for Loaders

1. Environmental Pre-Check:

• Conduct a full vehicle walk-around to clear obstacles; use mirrors and rear-view cameras, then sound the horn.

• Idle for 3-5 minutes in cold conditions until oil pressure stabilizes (0.2-0.4MPa).

2. Power Engagement Essentials:

• Ensure brake air pressure is adequate before shifting; never start with a load or abrupt acceleration.

• Adopt "gradual throttle-clutch release" to avoid drivetrain impact.

3. Core Driving Operations for Loaders

1. Chassis Connection Management:

• Remove and store the front-rear chassis safety link before driving; reinstall after operation.

• Engage the towing start lever on slopes and only drive forward (≤15° slope requires low speed).

2. Load Transportation Principles:

• Maintain the boom hinge 400mm above ground and bucket tilted back 15° to prevent spillage.

• Never transport with the bucket fully raised to avoid center of gravity shift.

4. Loading & Unloading Safety Protocols

1. Condition Adaptation Requirements:

• Commence full-load operation only when engine water/oil temperature ≤90℃; idle to cool if overheated.

• Align the loader chassis straight before loading, with the bucket parallel to the ground—no diagonal scooping.

2. Operation Taboos:

• Use high gear for loading only with bulk grain; never raise the bucket while moving.

• Ensure balanced loading to prevent frame deformation from uneven stress.

3. High-Risk Operation Prevention:

• Never leave the cab with the bucket raised; lower it to the ground when stopping.

• Prohibit using the bucket to lift personnel; keep clear of the bucket underside when raised.

• Maintain safe distance from power lines (≥3m for 10kV, ≥5m for 35kV).

4. Unloading Operation Standards:

• Tilt the bucket gently when unloading to avoid truck damage; do not force operation if 受阻 (blocked).

• Return the shift lever to neutral and reconnect the chassis safety link after work.

Operational Efficiency Tips

• Perform 5-min no-load test run in complex conditions to preheat hydraulics.

• Track loader operation data to build a maintenance log for wear trend analysis.

Adhering to these standards reduces loader failure rates by 40%. Customize the guide with your equipment manual to enhance efficiency and safety in all operations.
