The Correct Operation Procedures for a Hydraulic Stacker

Hydraulic stackers as the core equipment in modern warehousing and logistics, possess highly efficient and precise cargo handling capabilities, significantly enhancing the efficiency of storage. However, improper operation may lead to equipment damage, cargo tipping, and even casualties. Shengyu will introduce the correct operation procedures for hydraulic stackers, helping operators conduct their work in a standardized manner and ensuring safety and efficiency.

I. Pre-operation Preparation:

Equipment Inspection

Hydraulic System: Check if the hydraulic oil level is within the scale line, and ensure that the oil pipes have no leakage or aging. The hydraulic cylinders operate smoothly without abnormal sounds.

Electrical System: Confirm that the power lines are undamaged, and that safety devices such as emergency stop buttons and limit switches are sensitive and reliable.

Mechanical Structure: Check that the forks, mast, chains, etc. have no cracks or deformations, and that the fastening bolts are not loose.

Tires/Tracks: Ensure that the walking wheels or tracks are not blocked by foreign objects, and that the braking device is effective.

II. Startup and Debugging:

Startup Procedure

Key Switch: Insert the key and rotate it clockwise to the "ON" position. Observe whether the indicator lights on the dashboard are functioning properly (such as hydraulic oil pressure, battery voltage).

No-load Test Run:

Slowly operate the mast lifting handle to check if the mast movement is smooth, without sticking or abnormal noise.

Test the front/rear tilt function of the mast and confirm that the tilt angle is within the safe range (usually ≤ 3°).

Travel Test: Drive at a low speed for 2-3 meters to check if the steering is flexible and the braking distance meets the standard (≤ 1 meter).

Parameter settings

Adjust the width of the forks according to the height of the goods to ensure it matches the size of the pallet.

Install a height-limiting device (such as a laser sensor) to prevent the forks from colliding with the top of the shelves.

III. Cargo Handling:

Picking-up operation

Positioning: Drive the hydraulic stackers to be in front of the goods, align the centerline of the forks with the center of the pallet, and the distance should be ≤ 10cm.

Lower the forks: Slowly operate the handle to insert the forks into the pallet holes, the depth should be ≥ 2/3 of the pallet depth.

Raise the goods: After confirming that the forks are fully bearing the goods, lift the forks at a uniform speed to a safe height (≥ 20cm from the ground), avoid rapid ascent which may cause the goods to slide.

Transportation process

Travel speed: Empty load speed ≤ 5 km/h, loaded load speed ≤ 3 km/h, turning radius ≥ 2 meters.

Visibility management: When transporting goods at a high position, operators need to reverse to drive and keep clear vision.

Avoidance rules: When encountering pedestrians or other equipment, actively stop and give way, and it is prohibited to rush.

Stacking operation

Positioning the shelves: Align the goods with the target storage location. The front end of the forklift mast should be no more than 5cm away from the crossbeam of the shelf.

Slow descent: Lower the forklift mast at a speed of no more than 0.5m/s until the goods are completely placed on the shelf.

Retracting the forklift mast: After confirming the stability of the goods, slowly retract the forklift mast to avoid scratching the shelf or the goods.

IV. Shutdown:

Return of the forks: Lower the forks to the lowest position and restore the mast to a vertical state.

Power off: Rotate the key counterclockwise to the "OFF" position and remove the key.

Brake lock: Pull up the handbrake to prevent the equipment from sliding.
