Choosing the right MULE (Material Unit Lift Enhancer) for your construction or material handling job is essential to optimize efficiency, cost, and performance on-site. With the introduction of the new MZ100 model, alongside the existing ML150, it’s crucial to understand the differences and advantages of each to select the one that best suits your needs. Let’s delve into the specifications and key features of both models to aid in your decision-making process.

Let’s examine the two models by looking at their key specs:


MZ100 vs. ML150: Specifications Comparison

Machine Weight and Dimensions:

  • The MZ100 is significantly lighter and smaller, with a machine weight of 809 lbs (367 kg), making it more cost-effective to transport. Its compact design features a stowed length of 6 ft 11 in (2.10 m) and stowed width of 2 ft 4 in (0.71 m).
  • The ML150 is heavier at 1,160 lbs (526 kg), requiring more space and potentially higher transportation costs. It has a larger stowed size, with a length of 8 ft 10 in (2.69 m) and width of 3 ft 1 in (0.93 m).

Lifting Capacity and Reach:

  • Both models offer a 12 ft (3.65 m) reach radius, but the MZ100 has a lifting capacity of 100 lbs (45 kg), while the ML150 can lift up to 150 lbs (68 kg).
  • The ML150 has a vertical travel/reach of up to 10 ft (3.05 m) without extensions, whereas the MZ100 can reach up to 20 ft (6.09 m), offering greater flexibility in height without needing additional accessories.

Power and Operation:

  • The MZ100 operates on a lithium-ion battery or 120V AC, offering up to 30 hours of run time and the convenience of operating while charging.
  • The ML150 requires a 20A @ 120V AC power source, often necessitating onsite generators where power is not readily available.

Key Features and Design Considerations


  • Higher lifting capacity and the inclusion of more off-the-shelf attachments.
  • Onboard air system for custom grippers.
  • Requires a power source for operation, suitable for sites with generator access.


  • Enhanced mobility, lightweight design and battery operation.
  • Features a steel-reinforced belt to prevent the entanglement of data and power cords, addressing a common issue in construction environments.
  • Equipped with a three-link arm for increased flexibility and ease of maneuvering around obstacles, especially beneficial for indoor projects. The middle arm is removable for further size and weight reduction.

Interchangeability and Warranty: Both models share the same bolt connection pattern, allowing for interchangeability of bases and masts, which is advantageous for customers already owning compatible components. Additionally, both units are backed by an 18-month warranty from Construction Robotics, ensuring reliability and support.

Conclusion: The choice between the MZ100 and ML150 depends on your specific project requirements. The MZ100 is ideal for tasks requiring mobility, longer battery life, and maneuverability in tight spaces. On the other hand, the ML150 is better suited for jobs needing higher lifting capacities and the use of custom attachments, albeit with reliance on an external power source. Regardless of your choice, both models promise to enhance productivity and safety on the construction site.
