An articulating boom lift, often called a “knuckle boom” or “up-and-over boom,” is a kind of aerial work platform products with a boom arm that has multiple hinged sections or “knuckles.” This design gives the lift a unique ability to bend and maneuver around obstacles, which is its primary advantage over a straight, telescopic boom lift.
The TIANLU TRAB Series articulating boom lift is designed for precise navigation around obstacles, offering working heights from 10.82 m (35.5 ft) to 22.55 m (74.0 ft) and platform capacities of 200–250 kg (440.9–551.2 lbs). TIANLU TRAB series articulating boom lift (Knuckle Boom) models (TRAB09RE, TRAB12RE, TRAB12TRE, TRAB13TRE, TRAB14RE, TRAB16RE, TRAB19ARE, TRAB21ARE) are engineered with exceptional maneuverability for complex aerial tasks, blending flexibility, durability, and eco-friendly power options. Built with Q345 steel, advanced safety features, and electric/diesel power options, these articulating boom lifts excel in construction, maintenance, landscaping, and warehousing. Invest in the TRAB series boom lifts for reliable, flexible solutions that enhance productivity and safety.
An articulating boom lift, also known as a knuckle boom or up-and-over lift, is an aerial work platform with a multi-segmented, jointed arm that bends at “knuckles” to navigate over and around obstacles. Unlike telescopic boom lifts, which extend in a straight line, articulating booms offer superior maneuverability in tight or complex spaces, making them ideal for indoor maintenance or outdoor tasks with obstructions like beams or trees. The TRAB Series, with horizontal reaches up to 12.5 m (41.0 ft) and heights up to 22.55 m (74.0 ft), exemplifies this flexibility.
The TRAB Series includes four models—TRAB09RE, TRAB12RE, TRAB12TRE, TRAB13TRE, TRAB14RE, TRAB16RE, TRAB19ARE, TRAB21ARE—tailored for diverse job site needs. The table below summarizes their specifications of TRAB09RE, TRAB12TRE, TRAB16RE, and TRAB21ARE. If you want know more, please contact TIANLU Lift at sales@tianlulift.com.

The TRAB Series is engineered for precision, safety, and versatility, offering advanced features that distinguish it in the AWP market.
Articulating boom lifts like the TRAB Series offer distinct advantages over other AWPs, such as scissor lifts or telescopic boom lifts, making them ideal for complex work environments.
Not all articulating boom lifts are self-propelled. The TRAB Series includes self-propelled models (TRAB09RE, TRAB16RE, TRAB21ARE) with drive speeds up to 4.8 km/h (3.0 mph) and a crawler-based model (TRAB12TRE) with 1.3 km/h (0.8 mph) speed. However, the industry also offers towable articulating boom lifts, such as those from Shandong Starlink (9–18 m/29.5–59.1 ft height, $4,500–$20,000), which require towing by a vehicle.
Towable: Cost-effective for static tasks, with compact stowed dimensions for easy transport, but slower setup (10–15 minutes vs. 2–5 minutes).
Choosing between an articulating boom lift (like the TRAB Series) and a telescopic boom lift depends on job site requirements.
The TRAB Series is versatile, supporting a range of applications across industries.
