Introducing the MINIMAX™
The MINIMAX™ is a side-loading refuse truck to be operated by only one person. It is designed
primarily for the automatic collection of garbage carts with the use of a joystick-controlled Helping
TM
Hand
arm. The lifting capacity of this arm is 450 lbs at a maximum reach of 60 inches. On some
units, a tipper may also be installed. Manual pickup of garbage bags or cans is also possible with the
M
INIMAX™.
Product Overview
On most MINIMAX™ units, a Helping HandTM arm is installed on the right-hand side of the body. This
arm has “close grab” capability, allowing the operator to pick up a cart within 12 inches from side of
vehicle with no “swing out” movement.
INIMAX™ unit;
INIMAX™ unit;
The M
INIMAX™ is composed of a small curved wall body, with a capacity of 10 cubic yards, and a
2 cubic yard tailgate, making the total loading capacity of the vehicle to be 12 cubic yards.
The hopper swept volume is 0.92 cubic yard, using an 18-inch packer, which is also used to unload
the body through the tailgate opening. This feature is called “Auto-Eject Mode”.
The standard packer cycle time is 15 seconds at 1,200 RPM, and the “Auto-Eject Mode” cycle takes
40 seconds at 1,200 RPM.
The hopper may also be equipped with a full-size crusher panel (optional). It also features a hinged
door on the left-hand side and 1 or 2 hinged doors on the right-hand side (2 doors if an automated
arm is installed).
After many years of experience with side-loading refuse trucks, Labrie has developed this newly
designed M
INIMAX™ truck. This truck will deliver excellent performance and reliability thanks to its
new simpler, but sturdier construction.
The M
INIMAX™ is primarily designed to be operated by only one person.
If, however, the end-user chooses to operate the arm-equipped M
INIMAX™ with more than one
worker, they shall advise Labrie Enviroquip Group of this situation. Labrie will then determine and
supply, at the customer’s expense, the safety items that are required in such a case.
For more information on this, please contact LabriePlus (see page 4).
Introduction 3
Danger!
Failure to contact Labrie Enviroquip Group to report a situation where a unit is operated
by more than one worker at a time may result in unit and/or property damage, personal
injury or even death.
Service and Maintenance on the MINIMAX™
Maintenance on the MINIMAX™ is of paramount importance to ensure long-lasting durability of all its
moving parts as well as optimum performance in heavy work. Maintenance has to be done on almost
every system involved in the operation of the M
mechanical systems. Some parts are subjected to more wear and tear than others. Therefore, these
parts need regular maintenance and routine check-up to prevent signs of deterioration as soon as
possible.
In this manual you will find the most common maintenance and inspection procedures required for
the M
INIMAX™.
INIMAX™, such as the hydraulic, electrical and
