Make your operation its most productive

When your goal is maximizing your mining operation’s productivity, it’s all about cost per ton. The versatile WE1350 is engineered to improve both sides of the equation: low cycle times and utmost reliability to boost your tonnage, multiple features designed to minimize your fuel and maintenance costs.

  • Up to a 45% fuel consumption reduction*
  • 35% CO2 reduction*
  • Up to a 10-15% TCO advantage*

  • *Compared to mechanical loaders or HEX machines

Features and benefits

Wheel loader_literature link_SRhybriddrive_Loader.psd

Fuel efficient SR Hybrid Drive

The SR Hybrid Drive system is fully regenerative. During braking or retarding, electrical motors become generators and feed power back into the electrical system. This allows for up to 45% less fuel consumption than comparably sized mechanical drive wheel loaders.
Wheel loader_L-1350_literature link_KESS_key640_23.psd

Peak power on demand

The Kinetic Energy Storage System (KESS) works in concert with the SR Hybrid Drive to store significant horsepower captured from braking and direct it to supplement peak power demand. The result is fast cycle times for more tons per gallon/liter used or CO2 emitted.

Peak power controls that support operator efficiency on demand

The LINCS II network control system provides instant, real-time feedback and vital statistics, such as bucket height and angle, individual bucket payload, and total tons moved. All of it helps your operators maximize productivity by adjusting to conditions.

Attuned to operator comfort

The spacious, environmentally controlled cab offers great visibility, a comfortable ride and room for a trainer seat. Digital joysticks give your operators easy and responsive control, while the highly adjustable, heated/cooled seat helps minimize driver discomfort.

Fast, efficient maintenance

Multiple design features help keep your maintenance costs low: the integrated, patented drive system has few components resulting in longer maintenance intervals, multiple access points mean faster component change-out times and more uptime for your machine.

Handles multiple site duties

If your operation involves frequent equipment relocations, you’ll love this loader. It can keep the pit floor clean and level without support equipment, offers outstanding mobility and travel speed, and handles berm maintenance, road repair and cutting ramps.

Structural

Frames are fabricated from high strength, low-alloy steel with excellent weld characteristics and extreme low temperature properties. The front axle is an integral, fixed part of the front frame. The rear axle center oscillates 11 degrees.

Unique forged ball and socket joints are utilized in multiple pivot locations (lift arms, rear axle, frame articulation, hoist cylinders). These joints are superior in absorbing and distributing multi-directional stresses. Features easily replaceable brass liners for long life and easy maintenance.

High strength castings are used in key areas of fabricated structures to reduce stress and improve structural life.
