Lorry Loader Crane

A lorry loader crane, the common term in Europe and many other regions for what is often called a knuckleboom crane or articulating crane, is a highly versatile type of truck-mounted crane characterized by its multiple hinged arm sections. Unlike straight telescopic cranes, the lorry loader's arm folds like a finger, providing exceptional flexibility and the ability to reach over obstacles, under structures, and precisely place loads in confined spaces. It is the predominant choice for applications requiring loading and unloading of the truck's own cargo bed, as well as for placement of materials around a site. These cranes are renowned for their compact stowed size, impressive reach, and ability to handle a wide range of loads, from pallets and bricks to logs and construction materials. They are equipped with powerful hydraulic systems, a variety of attachments (grapples, hooks, pallet forks), and feature advanced safety systems like load moment indicators. Their efficiency in self-loading the transport vehicle makes them incredibly popular in logistics, construction, recycling, and forestry industries worldwide.

The Articulating Boom Geometry is the crane's defining feature. Instead of a straight telescoping boom, it consists of two, three, or even four main sections connected by hydraulic hinges (knuckles). This allows the crane to fold into an extremely compact package for transport, minimizing overall vehicle length and weight. In operation, this articulation provides unparalleled flexibility. The operator can "curl" the boom to reach over the cab of the truck, stretch out to place a load significantly behind the vehicle, or precisely maneuver a load in a complex 3D space with obstacles above and below. While many lorry loaders also have a telescoping extension within the main sections, it is the articulation that grants its signature ability to work in incredibly tight and confined spaces where a straight-boom crane would be ineffective. This makes it ideal for urban delivery, working inside warehouses, or navigating dense industrial sites.

A primary reason for its popularity is its Ability for True On-Board Loading and Over-Side Lifting. The crane is mounted on a slewing platform that provides full 360-degree continuous rotation. This allows it to effortlessly pick up a load from the ground beside the truck, swing it over the chassis, and place it directly onto the truck bed—enabling the vehicle to load and unload itself without any external equipment. This self-sufficiency drastically reduces dependency on forklifts and site-based cranes, saving time and money. Furthermore, the articulating boom can easily reach to unload from the front, middle, or rear of the truck bed with equal ease, and can place loads to either side of the vehicle with a much greater effective reach over the side than a straight boom of equivalent length, thanks to its ability to extend out horizontally.
