USA: Atlas Copco launches upgraded trowels

Atlas Copco’s

new BG245 and BG375 walk-

behind trowels excel at finishing concrete in

limited-access worksites, and close to walls

due to their compact bodies and light

weight.

The upgraded trowels

feature an adjust-

able clutch

to enhance

versatility; a

maintenance stand

to make servicing easy;

and a centrifugal clutch

for safe operations.

The trowels’

relatively light weight

and compact protec-

tion rings provide versatility on con-

crete slabs. The BG245 weighs 130 pounds (59 kg) and the

BG375 weighs 185 pounds (84 kg), making them easy to

manoeuvre. Each unit features four blades lengths, which

allows operators to tackle a wide range of projects, from

sidewalks to driveways.

The BG245 comes equipped with 24” long blades and

features a rubber edger to prevent damaging walls or

concrete, which makes it ideal for use on indoor worksites.

The BG375 includes 37” (584 mm) long blades for efficient

operation on larger, outdoor applications, such as drive-

ways. Both trowels come standard with a gas-powered,

high-capacity Honda or Vanguard engine.

The trowels’ quick pitch controls minimize set-up times

and enhance their versatility. Using the controls, operators

can adjust the angle of the blades and speed easily with-

out impacting productivity. This variable speed also means

operators can perform either high speed burnishing or low

speed, high torque floating.

The trowels also enhance operator safety. The units’

centrifugal clutches, commonly referred to as the dead

man’s grip, disconnect the drive train from the engine

as soon as the operator releases the grip. This stops the

blades within 180° of rotation, which not only improves

safety, but also minimizes costly damage to the concrete.

The trowels’ carrying handles are welded to the pro-

tection rings and support the trowels when the machines

are tilted forward for maintenance, such as cleaning or

changing blades. Contractors can fold the units’ operating

handles to save cargo space and load handling time during

transport.

The BG375 features a detachable throttle that can be

moved from the left handle to the right, which enhances

comfort and ease of use for left and right-handed opera-

tors.

Hitachi Japan launches

4 vibration rollers

Hitachi Construction Machinery Co., Ltd.

has int-

rouced four new vibration rollers - ZC35C-5 (2.80t),

ZC50C-5 (3.61t) are combined type (front wheels iron

drum, rear wheel tyres).

ZC35T-5 (3.03t), ZC50T-5 (4.08t) are tandem type

(drum of iron wheels both front and back).

In addition to the safety performance which has

followed the previous model the new models benefeit

from improved workability and maintenance proper-

ties.

These include direct-injection engines to help

achieve significant reduced fuel consumption.

A neutral forward-reverse lever means that it is not

possible to start the engine unless the parking brake is

applied.

The adoption of a direct injection engine with a rated

output of 18.2kW does not require a muffler filter for

lower maintenance.

It employs a full opening engine cover, further improv-

ing access to the inspection and maintenance points.

ZC50C-5 and ZC50T-5 models feature a conventional

Hi mode, in addition to the Lo mode. The super Lo mode

improves climbing ability

These models may not be made available worldwide.

Please check wiyh local dealer for availability. Configura-

tion may also vary according to regional regulations.
