Bucher MaxPowa V120

The MaxPowa V120 is the latest truck-mounted sweeper from Bucher Municipal, designed for heavy-duty work and construction sites. It builds on the modularity of the V series, but with a larger hopper and a more powerful auxiliary engine than the other models. A 12 m³ hopper and 5200 l of water in an integrated tank maximise time out on the job, and Bucher describes the machine as striking the right balance between performance, environmental impact and low cost of ownership. The machine fits 26-tonne chassis with a nominal wheelbase from 3900 to 4600 mm.

Engine and fan

The auxiliary engine is a JCB Dieselmax 448 NRMM in S Design, Stage 5, delivering 129 kW at 2200 rpm and 690 Nm at 1500 rpm. The engine fits into the existing Powapack, so that components are shared with the rest of the V series. A JCB Stage 5 engine of 97 kW at 2200 rpm and 550 Nm at 1500 rpm is available as an alternative.

The new three-plate fan – Tri-Plate – handles the increased power and provides optimised air flow; together with the new radiator position and Smoothflow air technology, this gives very good suction power. The fan speed is infinitely variable between 1800 and 3800 rpm to suit the job, and the V120t has a step-up gearbox with a ratio of 1.79:1. The bonnet has a Smoothflow design and is lined with frequency-tuned sound insulation. The alternative drive is hydrostatic (OMSI 600).

Sweeping equipment

The sweeping width is 1300 mm with suction mouth and side brush, 2400 mm with roller brush and 3600 mm with dual-sided pick-up. The suction mouth is made of cast aluminium with a 250 mm inlet diameter and is adjusted without tools. The side brush has a quick-change system and infinitely variable speed of up to 160 rpm, controlled from the cab, with the option of adjusting the brush pressure independently. Dust suppression consists of nozzles at the suction mouth, side brushes and across the front of the vehicle, plus the Pressadrain water purge system.

Hopper and water tank

The hopper unit consists of the hopper and an integrated water tank in heavy-duty stainless steel plate, with a watertight double-locking rear door with dewatering function, two side hatches and side lockers. The discharge angle is 56° nominal and the door opening angle 125° nominal. The water tank is made of stainless steel 1.4301, has anti-surge baffles and is filled via a type A hydrant coupling, while a double diaphragm pump can run continuously and dry. The standard water capacity is 5200 l, with up to 6900 l in total.

Cab and controls

The controls are designed around the driver. The 10-inch JVM screen has clear graphics, a shallow menu structure and up to six fully programmable buttons for custom sweeping settings, and is mounted on an articulated arm so that the angle and rotation can be adjusted without tools. A separate door controller with LED indicators operates the main functions, and a large pause button provides one-button operation. The centre console has cup holders and USB charging. A wireless discharge pendant lets the driver walk around the vehicle, tip the hopper and adjust the roller brush from a safe distance. A self-locking, highly visible hopper prop ensures safe working during servicing.

The external sound power is LWA 120 dB(A) for the high-output engines measured according to 2000/14/EC, while the noise level in the cab is below 75 dB(A) depending on the chosen chassis. The electrical system is 24 V with IP67-rated connectors throughout the external wiring.
