A flail mower demonstrates the versatility offered by a compact excavator, utilising the long reach and manoeuvrability of the carrier to cut vegetation in hard-to-reach places like hillsides and riverbanks. Two Bobcat flail mower attachments are available, the 30FM and 40FM, with working widths of 762 mm and 1016 mm and hydraulic flows of 46-74 l/min and 53-85 l/min, respectively. The 30FM model is designed for use on the Bobcat E32 and E35 compact excavators and the 40FM flail mower is intended for the Bobcat E45, E50 and E55 models, and both flail mowers offer high power output, with the ability to cut trees and branches up to 10 cm in diameter. Key features include a robust construction allowing the user to tackle the toughest environments and most uneven terrain. Preparing land for development Bobcat has launched new flail mower attachments for use on its market-leading range of compact excavators. The flail mowers are ideal tools for cutting and shredding vegetation, branches, thick grass, bushes and small trees alongside ditches, roads, hillsides, river banks, parks, fences and for preparing new land for development. Complete HiLight range unveiled Atlas Copco has expanded its range of HiLight towers to seven models, including four advanced LED solutions. Users have a variety of choices when it comes to sourcing safe and efficient light towers for multiple applications and industries, including construction, outdoor events and industrial applications. The HiLight range includes the H5+, B5+, V5+ and E3+ LED light towers, plus the V4, H4 and E2 metal halide variants. Atlas Copco’s latest LED light towers feature a unique, fully directional optic lens that maximizes practical light coverage while minimizing dark spots. A single HiLight LED light tower, depending on the model, can illuminate large areas with an average brightness of 20 lux. They also can run as long as 260 hours before needing to be refueled. The LED HiLight towers are designed with dedicated power packs that optimize power output. The power packs also minimize the risk of under-loading the engine, which enhances efficiency and improves power pack longevity. The LED lamps are designed for portability and performance with heavy-duty floodlights that offer high ingress protection (IP) and

A reversible, spiral mounted triple-knife design helps to deliver the smooth cutting action necessary to rip through hard and soft woods, grass, vines and brush. A compact deck allows the flail mowers to manage various ground contours, maintaining surface contact for efficient cutting. A direct drive motor provides an ideal balance between torque and rpm for optimal performance, with no belts, chains or gearboxes involved for maximum uptime. The flails are reversible, providing bi-directional rotation by switching the hydraulic hoses at the drive motor, which is equipped with a check valve to prevent damage from the change in direction of rotation. A rubber torsion disk absorbs impact loads during operation, whilst the heavy duty flanges on both sides of the rotor protect the drive train from dust and debris. A case drain prevents excessive back pressure and side safety chains help deflect and contain debris within the housing that could be thrown out during operation. A rotor brake slows the mower from full speed to stationary in seven seconds or less after the flail mower hydraulics have been deactivated. 

impact protection (IK) ratings. The LED lamps also offer extreme durability without deterioration in lux level while providing instant light. The bulbs also require minimal fuel, which reduces CO 2 emissions by 70% on each model. Atlas Copco’s HiLight H5+ is ideal for large construction sites where workers are constantly on the move. The unit offers low fuel consumption and each of its four LED lamps project 350 watts of light for a 5 400 m 2 illumination area. The H5+ is compact and easy to transport; contractors can fit as many as 10 units on a 42-foot trailer. Ideal for general construction

and tough mining conditions, the HiLight V5+ can also illuminate a 5 400 m 2 area while saving as much as 60 percent in fuel compared to the typical fuel consumption of a 6-kilowatt metal halide solution. The LED lamps in the V5+ are designed for both portability and performance. Heavy-duty floodlights benefit from high ingress protection (IP) and impact protection (IK) ratings. 
