Fully Hydraulic Trailer Crane Expands Electric Lifting Technology

Böcker presented at DACH+HOLZ International 2026 in Cologne an electrically powered trailer crane with a fully hydraulic boom designed to combine flexibility, reach, and low-emission operation.  boecker.de The new AHK 36e X is an electrically driven trailer crane for construction and trade applications, integrating fully hydraulic boom technology with a battery-electric drive system. The unit targets construction, roofing, and installation projects where reach, payload, and flexible setup conditions are critical. Technological Development in the Trailer Crane Segment With the AHK 36e X, Böcker has expanded its portfolio of mobile lifting systems with a model featuring a fully hydraulic telescopic boom. The system was introduced at DACH+HOLZ International 2026 in Cologne. The development addresses increasing requirements for low-emission processes, reduced noise levels, and performance comparable to combustion-engine systems on job sites. The trailer crane combines an electric winch with a battery-electric drive and integrated energy management. The concept enables typical construction applications without an external power supply while maintaining competitive operating speeds. Fully Hydraulic Boom for Flexible Operation A key technical feature is the standard dual fully hydraulic telescopic boom with a length of 11 m. It can be extended via radio remote control and supports loads up to 500 kg even when fully extended. An optional mechanical extension further increases reach. The hydraulic telescoping system allows extension under load, enabling material to be positioned directly inside buildings. The design also supports automated crane setup in confined ground-level conditions. The crane achieves a maximum extension length of up to 34 m, optionally 36 m. Use as an Aerial Work Platform In addition to lifting operations, the system can be configured as an aerial work platform. In basket mode, it reaches a working height of up to 32 m. The hydraulic boom system enables flexible repositioning during operation, which is relevant for façade work and roof installations. Electric Drive System with Energy Recovery The electric drive concept is based on a 12.2 kWh battery pack. According to the manufacturer, the system supports up to 140 standard lifting cycles or a full working day without grid connection. The integrated 1.5 t electric winch delivers high rope speeds and incorporates energy recovery during load lowering. Charging is compatible with standard 230 V outlets and can take place during downtime or parallel to operation. With a maximum payload of 1,500 kg, or optionally 2,400 kg in two-fall operation, the system reaches performance levels comparable to combustion-powered alternatives while enabling low-emission and low-noise operation. Revised Chassis for Improved Site Accessibility The redesigned chassis focuses on transport stability and maneuverability. In transport position, the outriggers are pivoted forward along the chassis, improving the rear departure angle by 25%. This structural adjustment increases ground clearance and facilitates movement across slopes, gradients, and uneven terrain. Optional Counterweight System for Extended Reach An optional counterweight system consisting of modular weight plates can be mounted on the slewing column after crane setup. This configuration increases the working radius: with a suspended load of 250 kg, the reach expands by approximately 2 m in all directions. The counterweights are designed for ergonomic handling and can be installed by a single operator without additional tools. By combining fully hydraulic boom technology, battery-electric drive, and structural refinements, the trailer crane addresses the technical requirements of modern construction sites, particularly in terms of emission reduction, operational flexibility, and efficient logistics. www.boecker.com Powered by Induportals Media Publishing
