The Lull 844TT-34 is a powerful, versatile telehandler known for its high lifting capacity and robust design. Used primarily in construction and industrial settings, this equipment is recognized for its ability to handle heavy lifting in tight spaces. Over time, however, many operators have encountered various challenges and maintenance concerns with older models, which has sparked numerous discussions and inquiries about their functionality and repair needs.
Overview of the Lull 844TT-34 Telehandler
The Lull 844TT-34 is a high-performance telehandler, engineered for heavy-duty use. Telehandlers, also known as "telescopic handlers," are essentially a hybrid between a forklift and a crane, capable of lifting loads to great heights and across large distances. With a lifting capacity of up to 8,000 pounds (approximately 3,629 kg) and a maximum lift height of 34 feet (10.36 meters), the 844TT-34 is designed to tackle a wide range of tasks, including lifting heavy loads onto elevated platforms, moving materials around a job site, and unloading supplies.
This particular model features four-wheel drive for enhanced mobility in rugged terrain, making it ideal for construction sites and agricultural operations where maneuverability and power are crucial. Its telescopic boom allows it to extend and retract with precision, providing excellent reach.
Common Issues with Older Lull 844TT-34 Models
As with many older machines, the Lull 844TT-34 has a history of being well-maintained and reliable, but issues do arise as the machinery ages. Some of the common problems reported by users include:
Given the challenges faced by older Lull 844TT-34 models, operators should follow a strict maintenance regimen to prolong the lifespan of the equipment. Some important tips include:
Upgrading or retrofitting some components can help enhance the performance of older Lull 844TT-34 units. For example, replacing worn-out hydraulic cylinders with newer, more efficient models can provide better lifting power. Similarly, modernizing the electrical system with more reliable components can reduce the frequency of issues. Additionally, an overhaul of the transmission system, including the replacement of worn-out clutch packs or gears, can significantly improve the responsiveness and reliability of the machine.
The Legacy of Lull Equipment
Lull Equipment, now a part of JLG Industries, has been manufacturing innovative lift equipment since 1959. Known for producing rugged and reliable telehandlers, Lull has been a go-to brand for heavy-duty equipment in industries such as construction and materials handling. The 844TT-34 model, like other Lull telehandlers, was designed to provide superior lifting and loading capabilities in tight and challenging work environments.
Although the Lull 844TT-34 was discontinued, its legacy still lives on through its reliable performance, particularly on large construction projects. The machine is known for its ruggedness and the ability to operate efficiently even in tough working conditions.
Conclusion
The Lull 844TT-34 is a workhorse that, with the right care and maintenance, can provide years of reliable service. Understanding the common issues faced by older models, and knowing how to prevent or address them, ensures that the machine continues to perform optimally. Regular maintenance, component upgrades, and a proactive approach to repairs can extend the life of this versatile piece of equipment. For those working with older Lull telehandlers, it’s essential to stay ahead of potential issues, keep up with maintenance schedules, and consult with professionals when needed. This proactive mindset will not only improve machine performance but also enhance overall site productivity.

Common Issues with Older Lull 844TT-34 Models
As with many older machines, the Lull 844TT-34 has a history of being well-maintained and reliable, but issues do arise as the machinery ages. Some of the common problems reported by users include:
- Hydraulic System Failures: The hydraulic system, which controls the boom, forks, and other components, is integral to the machine's functionality. Over time, seals may wear out, or the hydraulic fluid may degrade, leading to a loss of performance. Regular maintenance is critical to ensuring that the hydraulic pumps and cylinders are functioning optimally.
- Electrical Problems: As telehandlers age, electrical systems can deteriorate. Users have reported issues with the electrical wiring, fuse boxes, and sensors, which can affect the operation of key systems, such as lifting and steering. A common solution involves tracing electrical faults and replacing damaged components.
- Transmission Issues: Some operators of older Lull 844TT-34 models have experienced problems with the transmission, including slipping or failure to engage properly. This can be caused by worn-out clutch packs, low transmission fluid, or issues within the differential. A comprehensive inspection of the drivetrain is necessary to identify the root cause.
- Wear on Tires and Undercarriage: Due to the machine's heavy use, the tires and undercarriage often experience significant wear. Replacing worn-out tires is common, but more critical is the condition of the axle bearings, suspension components, and frame integrity, which must be regularly checked to avoid further damage.
- Engine Performance Issues: Engine problems can include rough idling, excessive smoke, or failure to start. These issues can often be attributed to aging components such as fuel injectors, the fuel system, or even air filters that need to be replaced. A thorough engine diagnostic check can pinpoint the exact issue.
Given the challenges faced by older Lull 844TT-34 models, operators should follow a strict maintenance regimen to prolong the lifespan of the equipment. Some important tips include:
- Regular Fluid Checks and Changes: Keeping hydraulic fluid, transmission fluid, and engine oil at the proper levels and changing them according to the manufacturer’s recommendations is essential. This ensures that the machine runs smoothly and reduces the risk of system failures.
- Hydraulic System Inspections: Checking the hydraulic hoses and seals for leaks is critical. Replacing worn hoses and seals before they fail can prevent extensive damage to the hydraulic pumps and cylinders. It’s also essential to check for proper fluid levels and quality regularly.
- Engine and Fuel System Care: Ensure that the engine air filter is cleaned or replaced periodically, as a clogged air filter can lead to poor engine performance. Likewise, the fuel injectors should be checked to make sure they’re delivering the proper fuel flow for optimal combustion.
- Tire and Undercarriage Maintenance: Given the harsh conditions under which telehandlers operate, regular checks on the tires for wear and pressure are crucial. Additionally, inspecting the undercarriage for any potential damage to the frame or axle bearings should be part of routine maintenance.
- Electrical System Monitoring: The electrical system should be checked for damaged wires, blown fuses, or faulty sensors. Diagnosing electrical issues early can save significant time and money on repairs down the line.
Upgrading or retrofitting some components can help enhance the performance of older Lull 844TT-34 units. For example, replacing worn-out hydraulic cylinders with newer, more efficient models can provide better lifting power.
