Alpha Construction


Productivity development is the continuous process for SDLG. The power, the speed, the manoeuvrability – all results of SDLG’s environment-friendly BS – III engines, transmissions, axles, hydraulics and lift arm system. They work together in perfect harmony, helping the operator to get more work done, in less time, with less effort.

The most suitable 4 Ton class Wheel Loader for Bulk cargo handling in, Road Projects, Stone Crushers, Ports, Coal re handling, Iron ore mines etc where longer duty cycles are the need.

  • Weichai Deutz BS III Engine
    World class electronically controlled Weichai Deutz BS – III engine enables high torque at low rpm. Low fuel consumption, high life engines meet the Indian standards. The engine is designed to reduce sound level in the cab to ensure better operator comfort and performance. The Turbocharged low-emission, high-performance CRDIengine is equipped with air to – air intercooler. Its Electronic engine control unit regulates fuel for optimal performance in all operating situations. The “3″ Power Modes are unique to the SDLG Loaders in this class.
  • Power shift planetary transmission
    Specially designed 5 ton capacity power shift planetary transmission with two forward and one reverse speed coupled with twin turbine torque converter for smooth gear shifting and long life.
  • In-house developed axles
    SDLG’s axles are an integrated part of the drive train; it adopts the strengthened driving axle featuring latest technology and performance. It provides greater bearing force, machine stability and reliability.


  • Smooth and effective braking
    SDLG Loaders are enhanced with SDLG’s Air over hydraulic disc brakes. They have long operating life, service friendly and enables smooth and effective braking action with power cut off function. The emergency brake is electro mechanically operated.
  • Hydraulic System
    Patented hydraulic control mechanism with double pump and Load sensing Orbital Valve makes the operation more operator friendly, higher production and increased reliability. Working pump matched with the engine power which greatly increases the production efficiency. Improved seal structure adopted for the whole hydraulic hoses which increases the sealing reliability.
    The single Joy stick pilot control system enhances smooth & fast operating & reduces operator fatigue.
  • Clean and comfortable workspace
    SDLG provides excellent workspace for the operators. The cab is ergonomically designed with inbuilt air conditioner as standard fitment for optimum operator performance with reduced noise inside the cab. Large windscreens, narrow pillars ensure panoramic visibility, thus further increasing safety, Comfort and Productivity go hand-in-hand.
