Electric forklift trucks (FLT), series EV-VR, are general purpose hoisting & hauling equipment for carrying and tiering materials in stores, at stations, ports and airports, as well as for handling loads into & between workshops. The series is available in range of load capacities 1.25 and 1.5 tons and lifting heights within the range 2800 to 4500 mm.
EV-VR 1.25 and EV-VR 1.5 could be distinguished by their modern design, high maneuverability, being a benefit from its minimized overall dimensions, reliability and ergonomics. Electric FLT are adapted for use in temperate climatic zone within temperature range between -25 and +45o C, on explosion-proof and fire-proof premises.

Chassis
It is a tough welded steel construction, box-like and maximum stiff, ensuring good protection, free approach for maintenance of the assemblies and components and long life of the truck itself.
The built-in control panel, with automotive layout, provides maximum comfort in the driver’s compartment. The control instruments and devices are ordered in conformity with the present-day ergonomic and occupational safety requirements.
Drive axle
The transmission assembly consists of main drive and differential gear.
The traction electric motor is fixed to the axle immediately.
The whole driveline module could be removed not disassembling the lifting equipment.
Steering Axle
Its construction covers large angle of turning the steered wheels thus enabling minimal turning radius and high maneuverability for FLT. It consists of a firm steel beam, double-action hydraulic piston cylinder and classical ball joints. The hydraulic cylinder is powered by a hydrostatic servo-amplifier with a safety valve built in to preserve the system from shocks on the steering wheels. In case of a power failure in the electric system the FLT could be steered by without the servo, as well.
Hydraulic system
A separate gear pump provides pressure for the operation hydraulic. The oil-tank volume is quite enough even if the truck should be equipped with forklift attachments. Safety valves assure slow lowering of the load, even in case of a torn hydraulic hose. Tilting speed also could be set by an adjustable flow-restricting stopcock valve.
Control of the hydraulic system is carried out by a three-sectional (standard equipment) or four-sectional valve with direct relief valve built-in to assure overload preservation for the system.
Electric system
Control of the series EV-VR forklift trucks is performed by a pulse controller “Curtis. By request, the Electric system can be made of relay-resistor indirection type.
The electric FLT are offered with a standard traction battery

The battery enables full-duty operation for about 6 – 8 hours.
Standard electric system includes:
• beam headlight and tail beams;
• direction indicators;
• brake-lights;
• back up alarm.
Amber flashing beacon on the top of the overhead guard is an option.
A capacity indicator is placed on the control panel to read the state of the Battery, direction indicator warning lights and a signal light for operating voltage presence. Hour meter is an option.
Brake system
The brakes are hydraulic powered and the brake assembly is small thus advancing good ergonomics in the driver’s compartment.
Lifting mast
It is a two- or three-stage welded construction made of hot-rolled high-strength profile steel.
It could be three types:
Simplex - It provides wide view for the operator. It consists of two-stages, two hydraulic cylinders on both sides of the static mast, low free lift.
Duplex - It consists of two-stages, central hydraulic cylinder, full-free lift.
Triplex - It consists of three-stages, two lateral and one central cylinders and full-free lift.
FLT are generally equipped with forks that could be replaced by various other attachments for specialized or enhanced use – side-shifter, fork positioner, rotating devices, clamps, fork extensions, etc.
