A note about machine class designations and specifications :

Because of the large number of machines stocked at our various branches (and ever-changing inventory) it is not possible to provide you spec sheets on each individual unit within our system.  Therefore, we have selected a sample model from each category that is reasonably representative of most machines that we stock which fall into that same category.  For instance, the unit below will provide you typical specifications for all machines in this particular class or size category.

A word of caution: If a particular dimension or specification is of critical importance to the success of your project, please speak to our dispatchers about that directly - do not assume that the specifications listed here will be exactly what you will get when your machine arrives.  The onus is on you to ensure the machine you order will do what you need it to.   For instance, if you have a width or height restriction, be sure to measure exactly what your minimum clearance is.  For example, if you have only 48" clearance for width, do not assume that a machine ordered in the 4-foot class will fit - it could easily measure 49" or 50", and still be considered a 4-foot class machine.  The same goes for dig-depth, reach, weight, lift height, lift capacity, and so on.

approx specifications

for this machine category:

Standard Mini-excavator class

*machine width (minimum access req'd for machine to enter dig area): 39 inches

practical working width (to allow minimal dig, swing, dump cycle):    5-6 ft

minimal swing width (to allow 180-degree turn to dump behind):     8-10 ft

tail swing type (conventional / zero tail / zero house):                conventional

machine height (to top of cab, for access to dig area):                         86 inches

     (remember, boom requires much more height to actually dig once in the dig area)

machine weight / excavator weight class:               3500 lbs / 1.75 ton

tracks (type):                                        rubber, expandable

engine (fuel, appx horsepwr):                                diesel, 14 hp

lift capacity (load in tight to machine, just in front of blade):  650 lbs

       (when boom-load is further outstretched, capacity diminished due to leverage factor)

maximum dig depth:                                               7.5 feet

maximum practical digging depth:                            6-7 feet

maximum reach, at ground level:                            13 feet

bucket sizes: width (typical sizes; specify if important):     10, 16 inches

special features (might be present, some units):retractable tracks, hyd clamp

* when measuring for clearances such as width, height, etc, ensure to take into account uneven/sloping ground, protrusions (pipes), sharp corners to turn, etc.

When you order this machine without any additional attachments, what does it come with, standard?

Our mini-excavators always come with a standard trenching bucket, the best size to suit the machine for maximum efficiency.  Additionally, some machines may travel with additional bucket sizes as well; but don't count on this - if you require a particular bucket size (ie narrower) specify that at the time of ordering, with dispatch.

Any additional attachments you want must be specifically ordered when you book your machine.  Rental charges will apply.

Comment regarding the most useful application of this machine category:

A standard sized mini-excavator is a good choice for any simple excavating project.  These units are compact and easy to transport, can go almost anywhere.  Power and weight are generally more than adequate.  If you need to dig anything up to about 5 or 6 feet deep, and fairly narrow - this is the machine to go with.  If you are heading deeper than 7 feet and have the room for it, move up to a bigger model.  The difference on a 100 foot trench 2 feet wide and 7 feet deep between this size machine and the next size or two up is night and day.  The bigger machines have more weight, more power and much bigger buckets (deeper pocket, not just wider - so they pull out a lot more dirt on each dig cycle).  Plus they can use a lot more attachments than the smaller units.   But if your project is smaller, or your access just too tight, go with this size - you won't be disappointed.
