W-Beam Guardrail Installation Vehicle
The BHZ4-XC battery-electric W-beam guardrail installation trolley is engineered for high-volume highway barrier installation. A truck chassis carries up to 10 tonnes of W-beam stock, while a truss-mounted robotic arm with a magnetic gripper handles automated pickup and precise placement. A speed-synchronised feeder delivers each panel in step with vehicle travel, removing manual lifting from the installation crew.
Features
Lithium-iron-phosphate traction batteries power both travel and work functions for zero on-site exhaust emissions
Wirelessly controlled motorised canopy protects W-beam stock and equipment during transport and operation
Three-axis servo-driven truss robot with linear guides, rack-and-pinion drive, and self-lubrication delivers precise barrier placement
Electro-permanent magnetic gripper rated at 120 kg lifting force handles 4 m three-wave guardrail panels, with the magnet only drawing current during 1-3 second magnetise/demagnetise cycles to conserve battery
Speed-synchronised feeder co-ordinates with the truss robot to deliver each panel to its preset position with no surface damage
Smart control logic, on-board diagnostics, fault alarms, construction logging, and 360-degree forward and reverse cameras support a low-headcount work crew
Enclosed climate-controlled cab for operator comfort on extended installation runs
