45' Knuckle Boom Description

The JLG 45' knuckle boom is a piece of heavy equipment used in construction and industrial settings. It has a reach of up to 45 feet, making it perfect for tasks such as building maintenance, painting, window cleaning, and installing overhead utilities just to name a few.

A key feature of the JLG 45' knuckle boom is its articulating boom, which gives it the ability to bend and reach around obstacles with ease. The boom is made up of several hinged segments which can be adjusted to reach a wide variety of heights and angles.

It has a hydraulic system that controls the movement providing smooth and efficient operation. Usually powered by a diesel engine, some models may run on electricity.

The JLG 45' knuckle boom comes with safety features including sensors and alarms to alert the operator of potential hazards. It also has a sturdy base and stabilizers to keep it from tipping over.

45 foot Knuckle Boom Lift Questions

The working height is typically around 45 to 50 feet, because manufacturers usually add about 6-7 feet to account for the operator's standing height. The horizontal reach (how far it extends outwards) is usually between 20 to 23 feet, depending on the specific model.

The weight capacity of a 45 ft knuckle boom lift typically ranges from 500 to 1000 pounds.

Yes, a 45 ft gas-powered knuckle boom lift can be used indoors, but there are some important considerations. Ventilation: Gas engines produce emissions, so you'll need proper ventilation to prevent the buildup of carbon monoxide and other harmful gases indoors.

The 45' gas knuckle boom is powered by diesel.

Yes, operators must have training and certification in accordance with OSHA (Occupational Safety and Health Administration) regulations.

A 45 ft gas-powered knuckle boom lift typically weighs between 12,000 and 16,000 pounds.

Standard safety features include an emergency stop button, fall protection lanyard attachment points, and platform controls with safety interlocks.

Straight boom lifts are designed for rough terrain and can operate on uneven surfaces, but this depends on the specific tires and drive systems of the model.

Boom lifts generally move slowly for safety reasons, with travel speeds around 3-5 mph on the ground.

Most manufacturers recommend not operating boom lifts in winds exceeding 20-25 mph for safety reasons.

A straight boom lift has a single, extendable arm that moves in a straight line, while an articulated boom lift has multiple sections that can bend or pivot, allowing for more versatile movement.

3 Key Benefits

Extended Reach for High and Remote Locations


The primary advantage of a straight boom lift is its reach. Unlike articulated boom lifts, which have multiple joints, a straight boom lift extends in a straight line, giving it the ability to reach heights ranging from 40 to 180 feet. This feature makes these machines perfect for projects that require access to tall structures, such as high-rise buildings, bridges, or telecommunications towers.

With a telescopic boom lift, you can work directly over obstacles without needing to reposition the equipment frequently. This capability is invaluable in construction, maintenance, or tree trimming, where efficiency and precision are essential.

Stability and Precision


One of the main concerns when working at significant heights is stability. Straight boom lifts are designed with this in mind, providing a solid, stable platform even at full extension. The telescopic design makes sure that the platform remains steady, allowing workers to focus on their tasks without worrying about swaying or instability.

Along with stability, straight boom lifts offer perfect positioning. Since the boom extends in a straight line, operators can easily maneuver to the exact height and position required for the job. This precision is especially useful in industries like window washing, electrical installations, or large-scale painting projects, where a steady hand is vital.

Increased Load Capacity


Many straight boom lifts are designed to handle heavier loads, accommodating multiple workers, tools, and equipment at the same time. This makes them a great choice for projects that require more than one operator or involve heavy-duty equipment. By increasing the lift's load capacity, you can reduce downtime and improve overall efficiency, since trips are needed to transport workers and materials to the elevated area.

As an example, in a construction setting, a straight boom lift allows workers to bring necessary tools and supplies to the work area without making multiple ascents, saving time and reducing the physical strain on workers.
