Midi-Ex Class
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.
example shown:
Bobcat 337
Attachments approved / available for this class
There are over a dozen types of attachments that are made for this class of machine, a number of which we stock. Popular ones are - Augers (bit sizes 6-36"), concrete breakers, grapples/clamps, frost rippers, among some that we stock. Check with dispatch to determine local availability.
approx specifications

Midi-Excavator class
*machine width (minimum access req'd for machine to enter dig area): 76 inches
practical working width (to allow minimal dig, swing, dump cycle): 10 ft
minimal swing width (to allow 180-degree turn to dump behind): 14 ft
tail swing type (conventional / zero tail / zero house): conventional
machine height (to top of cab, for access to dig area): 98 inches

tracks (type):
rubber
rubberengine (fuel, appx horsepwr): diesel, 49 hp
lift capacity (load in tight to machine, just in front of blade): 5400 lbs
(when boom-load is further outstretched, capacity diminished due to leverage factor)
maximum dig depth: 12 feet
maximum practical digging depth: 10 feet
maximum reach, at ground level: 19 feet
bucket sizes: width (typical sizes; specify if important): 16-36 inches
special features (might be present, some units):
* 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:
The compact excavator is a nice sized machine for a bit larger projects. It is a bit bigger than the typical mini-excavator, yet not quite in the midi-excavator range. So, it is still compact enough to get around many residential properties and into the backyards, it will fit indoors at most commercial or industrial sites, even those that are occupied building just undergoing renovation. Of course it is a useful machine on many road and bridgework sites, and other infrastructure projects. Because of the machine's greater weight and power it is able to accommodate much bigger buckets than the smaller machines can - these are deep-pocket buckets that can move a lot of dirt quickly. As a result, whenever a site allows access for a machine of this size, we recommend you go with one of these, unless the amount of work to be done is minimal, because when there is dirt to be moved, this machine can do it!
Add a concrete breaker, clamp or auger to the auxiliary hydraulics and the machine can take on a whole new range of tasks. If you need to dig a bit deeper or reach a bit farther, have a look at the next category, the Extenda-boom class, which is basically the same machinery as those in this category except some specific models come equipped with an extendible boom which allows the bucket to telescope much further than it normally would be able to if it did not have that feature.
