Specifications:
The document provides detailed specifications for the B1100 and B1120 single drum rollers. Key specifications include a compaction force of 305 kN, a gross weight of 11,800 kg, and a working width of 2,100 mm. The B1100 is equipped with a Perkins 1006-60 engine, while the B1120 features a turbocharged Perkins 1006-60T engine, both with a displacement of 6 liters and a fuel tank capacity of 260 liters.

Engine and Performance:
Both models have a 6-cylinder inline configuration with liquid cooling. The B1100 delivers 79 kW at 2,200 rpm, while the B1120 provides 108 kW at the same rpm. The rollers feature a hydrostatic travel drive with speeds ranging from 0-10 km/h for the B1100 and 0-12.5 km/h for the B1120, with a maximum gradeability of 45%.

Braking and Axles:
The braking system includes hydrostatic service brakes and hydro-mechanical emergency brakes. The axles are rigidly mounted with a differential type of no-spin differentials.

Dimensions and Weights:
The B1100 and B1120 have identical dimensions, with a total length of 6,600 mm and a width of 2,100 mm. The operating weights are 10,800 kg for the B1100 and 11,800 kg for the B1120.

Standard and Optional Equipment:
Standard equipment includes a ROPS panoramic operator's cab with features like a blower fan, heater, adjustable seat, and joystick with integral vibration control. Optional equipment includes a padfoot option with cleaning scrapers and segmented shells.

Key Features:
The document highlights the class-leading compaction performance, reinforced hydraulic drives, reverse engine design for reduced maintenance, and compliance with emission regulations. The ergonomic ROPS cab provides noise and vibration isolation, and the rollers feature rear drive axles with integrated brakes for safety.
