At Royal Forklift, we’re incredibly proud to be a Parker hydraulic hose dealer. Customers often come in because their previous hoses have failed. When you buy a Parker hose, however, you can rest assured it will hold up to your demands for a long time to come.
Hydraulic hose failure in forklifts can lead to disruptions in operations, safety hazards, and costly downtime. Understanding the common causes of hydraulic hose failure is important, because it can help you prevent downtime and keep your forklift’s hydraulic system running at peak performance. Here are a few of the reasons hydraulic hoses can fail.
Wear and Abrasion
Constant movement, contact with other surfaces, and environmental factors can cause wear and abrasion on hydraulic hoses. Hoses that rub against sharp edges, corners or other components can develop weak points and eventually lead to leaks or bursts. Regularly inspect hoses for signs of abrasion, such as worn areas or exposed wire reinforcement.
Excessive Pressure
Subjecting hydraulic hoses to pressures beyond their specified ratings can result in catastrophic failure. Overloading the forklift or operating the hydraulic system at pressures higher than recommended can cause hoses to rupture or fittings to detach. Always adhere to the manufacturer’s pressure guidelines to avoid exceeding the hoses’ capacity.
Improper Installation
Incorrect installation of hydraulic hoses is a leading cause of failure. Inadequate or uneven tightening of fittings, improper routing, or insufficient clearance for hose movement can lead to stress, kinks, or leaks. Ensure that hoses are installed according to manufacturer guidelines and industry best practices.
Twisting and Bending
Hydraulic hoses are designed to handle bending to a specific point. Excessive twisting or bending, especially near fittings, can weaken the hose structure and cause internal damage. Hoses that are improperly bent or twisted may develop kinks, which obstruct fluid flow and lead to pressure drops.
Chemical Degradation
The type of hydraulic fluid used in the system can affect the material of the hose. Incompatible fluids or exposure to certain chemicals can degrade the hose material over time, making it more prone to cracking, swelling, or brittleness. Ensure that the hydraulic hoses are compatible with the fluid used and replace hoses that have been exposed to aggressive substances.
Heat and UV Exposure
Extended exposure to high temperatures and ultraviolet (UV) radiation can deteriorate hydraulic hoses. Heat can cause hoses to become brittle and lose their flexibility, while UV rays can degrade the outer cover and weaken the reinforcement layers. Protect hoses from excessive heat and sunlight, and consider using heat-resistant or UV-resistant hoses when you can.
Age and Fatigue
Hydraulic hoses have a finite lifespan due to the stresses they endure during operation. Over time, the combination of pressure fluctuations, temperature changes, and flexing can lead to material fatigue. Regularly replace hoses that have reached their recommended service life or show signs of wear.
Incorrect Hose Type
Using the wrong type of hydraulic hose for the application can lead to premature failure. Different hoses are designed to handle specific pressures, temperatures, and fluids. Choosing a hose that doesn’t meet the requirements of your forklift’s hydraulic system can result in leaks, bursts, or reduced performance.
Vibration and Movement
Forklifts operate in dynamic environments that involve frequent movement and vibration. Excessive vibration or movement can stress the hose connections and fittings, potentially leading to loosening or detachment. Properly secure hoses and regularly inspect fittings for signs of movement.
