How a Telehandler Works
A telehandler operates on the principles of hydraulics and leverage. The engine provides the power, which is transferred to the hydraulic pumps. These pumps control the movement of hydraulic fluid, which in turn powers the boom and any attached implements.
Operational Mechanism
When the operator pushes the control levers, they activate the hydraulic pumps. The pumps then force hydraulic fluid through the system, causing the pistons inside the boom’s cylinders to move. This motion extends or retracts the boom, depending on the direction of fluid flow.
The forks or other attachments at the end of the boom are also controlled hydraulically. They can be tilted up or down to secure loads and prevent them from slipping off during lifting or transporting.
Telehandlers often feature four-wheel steering for enhanced maneuverability. Depending on the task and environment, the operator can choose between front-wheel, all-wheel, or crab steering.
Safety Measures and Precautions
Operating a telehandler requires training and awareness of safety measures. Here are some key precautions:
- Load Limit Adherence: Overloading can lead to tipping or mechanical failure. Always adhere to the manufacturer’s specified load limit and never attempt to lift a load heavier than this limit.
- Stability: Ensure the telehandler is on stable ground before lifting a load. Uneven surfaces can affect the machine’s balance and increase the risk of tipping.
- Visibility: The operator should always have a clear view of the load and surrounding area. If visibility is compromised, use a spotter to guide the operation.
- Regular Inspections: Before each use, inspect the telehandler for any signs of damage or wear. Regular maintenance checks are crucial to ensure the machine’s safety and efficiency.
- Proper Training: Only trained and certified operators should use a telehandler. Understanding the machine’s operation and safety features is essential for safe use.
A telehandler works by converting engine power into hydraulic power, which controls the boom and attachments. Safe operation requires adherence to load limits, stability, visibility, regular inspections, and proper training.
