Specifications:
The JCB Vibromax VM1500 is a vibratory trench roller with two drum width options: 850mm (33.5in) and 630mm (24.8in). It has an operating weight of 1500kg (3307lb) and a drum diameter of 500mm (19.7in). The overall height is 1280mm (50.4in), with a ground clearance of 170mm (6.7in). The roller's length is 1650mm (65in), and the total travel length is 1870mm (73.6in).

Performance:
The VM1500 features an exciter frequency of 31Hz, a nominal amplitude of 2.4mm (0.09in), and a centrifugal force of 84kN (18880lbf). It can compact up to a depth of 80cm (31.5in). The travel speed in the first gear is up to 1.1 km/h (0.07 mph) and in the second gear up to 2.5 km/h (1.6 mph). The gradeability is 24 degrees (45%) with vibration and 29 degrees (55%) without.

Propulsion and Braking:
The roller uses a hydrostatic drive with a variable displacement pump and two circuit drive to all four drums. The service brake is part of the hydrostatic propulsion system, while the parking brake is a hydraulically released multi-disk brake on the rear drums.

Engine:
Powered by a Kubota D1005-BB-EC engine, it is a three-cylinder, water-cooled, four-stroke diesel engine with a piston displacement of 1000 cm3 (61 in3). It delivers 16.8 kW (22.8 hp) at 3000 rpm. The engine features an automatic shutdown for low oil pressure and has a fuel consumption rate of 2.57 l/h (0.7 US gal/h).

Electrical System:
The system operates at 12V with a battery capacity of 66Ah and an alternator output of 14V (40A maximum).

Service Capacities:
The fuel tank holds 22 liters (5.8 US gal), engine oil capacity is 4 liters (4.2 US qt), exciter oil is 0.5 liters (0.53 US qt), and hydraulic oil capacity is 70 liters (18.5 US gal).

Features:
The VM1500 offers high centrifugal force and compaction depth, high torque drive motors for excellent gradeability, a hydrostatic parking brake, and wide opening enclosures for easy maintenance. It also provides an optional remote control for enhanced safety in trench applications.
