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.
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
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.
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.
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.
