Forklifts generate noise during transportation, mainly due to various factors such as mechanical component wear, excessive clearance, hydraulic system problems, and design defects. The following is a specific analysis of the reasons:

Mechanical component wear and excessive clearance

Clearance between guide wheel, roller and door frame: When the clearance between guide wheel, roller and door frame is too large, the forklift will produce significant friction and impact sound during operation.

Chain and link pin wear: Chain and link pin wear can cause excessive clearance and noise.

Gap between fork and fork frame crossbeam: Excessive clearance between fork and fork frame crossbeam can also generate noise.

Loose fasteners: The vehicle's guide wheels and rollers are severely worn, resulting in increased clearance and noise.

hydraulic system problem

Vacuum suction phenomenon: Hydraulic pump oil filter, inlet pipe blockage or high oil viscosity, resulting in high vacuum degree at the pump inlet, causing air to infiltrate and form cavitation phenomenon, producing cavitation noise.

Wear and tear of internal components of hydraulic pumps, such as the cylinder body and distribution plate, plunger and plunger hole of plunger pumps, causing severe leakage and flow pulsation, resulting in high noise.

Hydraulic pump distribution plate problem: The surface of the distribution plate is worn or oil sludge is deposited at the opening of the unloading groove, causing the unloading groove to become shorter and change the unloading position, resulting in trapped oil and causing high noise.

Other factors

Design flaws: Design flaws in forklifts can also lead to noise generation. For example, if the installation gap between the components of the gantry system is too large, there may be collisions between the steel groove and the rollers during operation, resulting in noise.

Improper operation: Improper operation may also lead to the generation of forklift noise. For example, when an electric forklift is not using the clutch during operation, placing the foot on the clutch pedal can cause the clutch to become semi interlocked, affecting power transmission and exacerbating wear on components such as clutch plates and separation bearings, resulting in noise.
