The ATM-7.5-12 lift (emergency technical vehicle) is designed for maintenance and repair of contact networks of trams and trolleybuses, as well as other work at a height of up to 8 meters with a scissor lift and up to 12 meters with a lever-telescopic lift. Provides transportation of a team of electricians with the necessary materials, parts and tools, as well as carrying out installation, preventive and repair work of contact networks using a working platform. The lift allows movement within the site of work with people on a raised working platform to a height of up to 5 meters to audit the contact network at a speed of up to 5 km/h. The lift is designed for movement on public roads in conditions of heavy traffic and tram tracks with an open rail-sleeper grid, as well as under bridges, overpasses and in tunnels.
DESIGN FEATURES OF THE LIFT
• four hydraulic outriggers
• cargo compartments for transporting materials
• pneumatic line to the working platform for the drive of a pneumatic tool or spray gun*
• additional autonomous pump for emergency lowering of the working platform and bringing the machine into the transport position
• remote control of lifting – lowering and transverse movement of the working platform
• hydro-mechanical locking system for spontaneous lowering of the working platform
• limit load limiter
• support position monitoring system
• electronic signal roll meter
• automatic device for blocking the lifting of the working platform above the set value for movement with people on the raised platform
• automatic locking device for horizontal movement of the working platform when outriggers are not exposed
• possibility of installing rail running equipment*
EQUIPMENT OF THE VAN BODY
• workbench with a pedestal*
• locksmith vise*
• tool storage rack*
