Loss of Pressure and Its Causes

Loss of pressure is one of the most common issues that you might face when operating a hydraulic dock leveller. Some potential causes include:

– Hydraulic fluid leaks: Just like how a car cannot function without oil, hydraulic dock levellers require hydraulic fluid to operate smoothly. If there is a leak in the system, it can cause a loss of pressure. Imagine driving your car without oil – not very effective, right?

– Pump failure: The pump is responsible for generating the force that makes the hydraulic system work. If the pump fails, it can cause a significant loss of pressure or even make the leveller fail altogether.

– Mechanical damage: Damage to any of the mechanical components within the system such as hoses, valves, and cylinders can cause loss of pressure. Over time, these components can become worn down or damaged due to regular use or harsh weather conditions.

While loss of pressure may be caused by a number of issues, it’s important to diagnose and address the problem quickly to prevent further damage or injury to personnel. Attempting to fix hydraulic dock levellers without proper knowledge could lead to costly mistakes.

In order to effectively maintain your hydraulic dock leveller and prevent issues such as loss of pressure or leveller tilt, it’s essential to follow a step-by-step maintenance guide. So, let’s take a look at some basic maintenance steps you should follow regularly.

Leveller Tilt and Worn Out Parts

Hydraulic dock levellers are designed to hold up heavy loads, but they are not indestructible. Over time, wear and tear can take a toll on your hydraulic dock leveller, leading to tilting issues and the wearing out of parts. A tilted dock leveller can be a dangerous situation as it can cause accidents by loading equipment to tip over. Let’s look at some common causes of leveller tilt and worn-out parts.

One anecdotal example is that of a warehouse owner who called in a technician because the leveller started tilting when they tried to load their trucks. After an inspection, the technician found that the main support beam was bent due to overloading beyond the manufacturer’s recommended weight limit. The solution was to replace the beam.

Another cause of tilting is worn-out parts such as hinge pins, locking cams or lip hinges which can lead to uneven levelling or unexpected movement during loading. As hydraulic systems get used more often, shields may come loose and cause leaks which affect the levelness of the platform. It is important for business owners to regularly inspect their dock levellers for signs of wear and address small issues before they turn into larger problems.

Replacing damaged components versus repairing them is always the choice presented when it comes to dock levellers repair services. While replacing worn-out parts seems convenient that is not always necessary. In some scenarios, hinge pins may only require lubrication rather than replacement because this can enhance its durability and performance without costing you more money.

Now that we have looked at leveller tilt, let us discuss thermal expansion.

  • Hydraulic dock levellers are subject to wear and tear, which can result in tilting and worn-out parts, leading to unsafe loading conditions. Business owners should regularly inspect their dock levellers for signs of wear and address small issues promptly to prevent larger problems. Replacing damaged components versus repairing them is always presented as a choice when it comes to dock leveller repair services. However, in certain situations, hinge pins may only require lubrication rather than replacement; this can enhance durability and performance while avoiding unnecessary costs. Therefore, it pays to be proactive in maintaining and servicing dock levellers to prevent accidents and ensure optimal operation.

Thermal Expansion in Hydraulic Systems

Thermal expansion refers to temperature changes within hydraulic fluid that expand or contract its volume accordingly. Since hydraulic systems operate under high pressure conditions, thermal expansion can cause issues such as pressure loss, decreased fluid lubrication capacity and even equipment failure.

For example, in a cold winter season, temperatures can affect the hydraulic fluid’s viscosity, making it flow poorly which affects it’s pumpability. In case you experience slow or no motion when trying to use your leveller systems during winter, it is best to allow to warm up for a bit before use.

Another problem is that of overheating due to prolonged use which leads to degraded fluid levels and poor performance. When this happens, service technicians will flush out old fluid from the hydraulic system and then replace it with new one. This is something business owners can do themselves in order to avoid higher costs.

While some argue that hydraulic fluids are resilient enough to combat thermal expansion, others insist that regular maintenance is always necessary for long-term performance. It is recommended businesses schedule routine system inspections at least twice or thrice annually to prevent unscheduled downtime due to unexpected damage caused by thermal expansion.

Next, we will take a look at our comprehensive step-by-step guide for dock leveller maintenance.
