URZ 7000 – Guillotine
This special machine is composed of a frame, a drive mechanism, running gear and work gear. A Perkins industrial diesel engine is mounted to the frame and powers a hydraulic system used to drive the running gear and the work gear. The running gear includes the front hydraulically drive and braked axle and a rear hydraulically steered axle. The working tool is a heavy steel plate with a wear resistant HARDOX 450 replaceable lower blade. The steel plate is repeatedly positioned at a pre-defined height and is then dropped onto the paved surface.The tool moves through vertical guides in the tower and is raised and released by a hydraulically driven winch.
The winch raises and releases the demolition tool. The working cycling begins by raising the tool to a pre-defined height, followed by the drive disengaging and releasing the brake, which allows the tool to fall. Once it falls on the demolished surface, the tool is raised and the entire cycle repeats.
The Perkins motor drives one main high-pressure piston control pump via a flexible adapter to move the drive gear and the winch as well as a gear pump for auxiliary and operating functions. The piston pumps drive the winch or drive gear based on the switchboard settings; the gear pump is used to steer the rear axle wheels, flush the winch, control the main manifold, the speed and braking of the drive gear, the brake on the winch and to stabilise the swing axles.
The controls are located in the driver’s cab. These are controllers and control instruments.
A remote control for the machine and cab air conditioning are available for an additional charge.
The electrical circuits on the machine operate using a 24 V DC system. An alternator on the diesel engine and two 12 V/180 Ah batteries power the system.
- Standard controls from the cab
- Radio remote control with colour display and camera (optional for an added charge)
