Qingzhou Mingxu Supply Chain supplies the EV300 electric loader, a compact battery-powered machine designed for light material handling in indoor and confined spaces. It is intended for use in factories, greenhouses, small construction sites, and similar environments where low noise and zero exhaust emissions are required.
The machine is driven entirely by an electric motor and is available for direct purchase, bulk orders, and export with optional configuration adjustments.

The EV300 is powered by a 48V battery pack. The drive motor controls forward and reverse movement, while the same power source drives the hydraulic pump for lifting and tilting the bucket. The system includes an electric overload protection function. Because there is no internal combustion engine, the machine produces no exhaust gases and operates at a reduced noise level, which makes it suitable for enclosed or populated work areas.
The control circuit is designed to protect the battery and motor from excessive current draw. When the machine is not actively lifting or moving, power consumption drops, helping to extend the working time between charges.
1. Pre-operation checks: Inspect tire condition, hydraulic hoses, and bucket frame. Confirm battery level and check for fault alerts on the dashboard. Make sure the emergency stop is reset and the charging port cover is closed.
2. Startup: Turn on the main power switch, fasten the seat belt, and turn the key to begin the self-check. Wait for the controller to indicate ready. Press the brake pedal and select forward or reverse, then test the hydraulic joystick movement.
3. Loading procedure: Level the bucket to enter the material pile, raise the boom and retract the bucket for transport, then lift and tip the bucket at the unloading point. Avoid sudden acceleration or hard braking to reduce energy consumption and extend battery life.
4. Shutdown and charging: Lower the empty bucket to the ground, idle for about 3 minutes to allow the controller and battery to cool, then switch off the main power. Connect the charging gun; the system will stop charging automatically when full.
5. Emergency response: If abnormal noise, battery overheating, or hydraulic leakage occurs, press the emergency stop and disconnect power immediately. Contact qualified service personnel before resuming operation.
1. Zero exhaust emissions. The electric loader runs entirely on battery power, with no fuel consumption or tailpipe output. This allows indoor use without additional ventilation.
2. Simple daily maintenance. The electric drive system has fewer wearing components than an engine-driven machine. Routine checks focus mainly on tires, hydraulic hoses, battery connections, and bucket edges. No engine oil, fuel filters, or exhaust system servicing is required.
3. Compact dimensions. With a turning radius of 1.5 m and a narrow body, the machine can work in tight spaces such as building interiors, greenhouses, and narrow warehouse aisles.
4. Attachment flexibility. Common attachments such as log grapples, sweepers, and extended buckets can be fitted, allowing the base machine to be adapted for different material handling tasks.
5. Direct supply. The loader is available directly from Qingzhou Mingxu Supply Chain for single-unit, bulk, or export orders. Configuration can be adjusted to match regional voltage and accessory requirements.
Lightweight structural design. The frame and primary load-bearing components are produced using high-strength lightweight steel. The design reduces unnecessary material without compromising the 300 kg rated load capacity. Optimized cross-sections and a simplified chassis layout help keep the total machine weight at 170 kg, which lowers energy consumption during travel and reduces floor loading when operating on finished indoor surfaces or elevated platforms.
Low-noise hydraulic matching. The hydraulic pump is coupled to the electric motor through a flexible connection that limits vibration transfer. Hydraulic piping is arranged to reduce fluid turbulence, and the control valve block is selected for quiet operation. Together with the low-speed electric motor, this configuration results in lower overall sound output compared with similar-capacity diesel equipment, making the EV300 suitable for noise-sensitive environments such as hospitals, residential areas, and indoor public spaces.
1. Industrial plants: indoor material feeding and waste removal in chemical, building material, food processing, and pharmaceutical facilities.
2. Municipal and sanitation work: light muck transport, waste yard stockpiling, and landscape earthwork in parks and public spaces.
3. Small mines and sand yards: material movement in enclosed processing areas or tunnels where exhaust fumes are restricted.
4. Agriculture and livestock: feed handling, manure cleaning, and forage stacking inside barns and greenhouses.
5. Port and logistics: bulk cargo handling in indoor warehouses and covered freight areas.
6. Infrastructure and renovation: confined space work in basements, subway tunnels, and indoor renovation projects.
7. Recycling operations: sorting station support and construction residue transfer.
The complete unit is covered for 12 months or 1,000 operating hours, whichever comes first. Core electrical components, including the battery, drive motor, and controller, are covered for 6 months. Manufacturing defects will be repaired free of charge using original parts. Damage resulting from improper use, overloading, or failure to follow charging and maintenance instructions will be charged at parts cost only. Transportation and labor costs for part replacement are the customer's responsibility. Wear items such as tires, bucket teeth, and hydraulic hoses are not included in the free warranty.
Q1: Can the EV300 work continuously for a full shift?
A1: The standard battery provides approximately 4 hours of operating time under normal loading conditions. For longer shifts, a spare battery can be kept on site and swapped, or the machine can be connected to a charger during breaks.
Q2: Is the machine suitable for outdoor use?
A2: Yes, the EV300 can operate outdoors on level or moderately uneven ground. However, it is primarily designed for light-duty tasks and should not be used in heavy rain or standing water, as the electrical components are not fully sealed for submersion.
Q3: What kind of maintenance is required?
A3: Daily checks include tire pressure, hydraulic hose condition, battery connections, and bucket edge wear. The hydraulic oil level should be checked periodically, and the battery terminals kept clean. No engine oil or fuel system maintenance is needed.
Q4: Can attachments be changed easily?
A4: Yes. The machine uses quick-attach interfaces for common attachments. Changing between a bucket, log grapple, or sweeper typically takes a few minutes and does not require special tools.
