What's New In plant & Equipment

Stage IV Diesel Engine For Concrete PumpsStage IV Diesel Engine For Concrete Pumps

Since 01/01/2014 in Europe and the USA Stage IV or Tier 4 final applies for mobile construction equipment, including for stationary concrete pumps. Mobile machinery, which is taken into service in the respective countries has to comply with the legal limits of stage IV. Particularly in urban areas or in environmental zones, these machines can also be without any problems.

The reduction of the emission limits for engines from 56 to 560 kW came into force in 2014. The new BSA D4 models from Putzmeister are fully compliant and come with efficient exhaust aftertreatment systems.

Putzmeister offers the latest generation of engines with the stationary pumps BSA 1407 BSA D4 and BSA 1409 D4.


Chicago Pneumatic portable generators

Chicago Pneumatic portable generators Chicago Pneumatic has launched a new range of portable generators, designed to provide a safe and stable power supply for every type of worksite.

The range comes in two distinct lines. The Standard Line and the Pro Line with petrol and diesel engine options includes Professional, Advanced and Advanced+ models designed for all-day, intensive heavy-duty applications and versatility. The Standard Line comprises simple, straightforward petrol generators designed for occasional use.

Looking more closely at the Pro Line, users can be protected by an optional Earth Leakage Relay (ELR), while Automatic Voltage Regulation (AVR) is an option for the petrol-engine unit that ensures consistent electrical output.

Alongside AVR, these models also protect users with an isometer protection and thermal protection circuit breaker.  The intuitive instrumentation panel, electric key start and a number of alarm and shutdown options are easy and practical to use.

The enclosure has sound insulation, allowing the generators to be used in sensitive areas. They comply with European noise regulations.

The petrol-only Standard Line is better suited for private and professional users who occasionally need a portable generator. Straightforward and simple, they are designed to do what is expected from a portable genset.

All models feature a strong main frame with extra reinforcement around sensitive components and a protected electrical panel. Sockets are also covered and recessed for enhanced protection.
