Narrow access

Micro Digger Access Envelope Checker

Compare the measured route with the exact transport width, height and operating boundaries supplied for the named machine. Gate clearance, corners, slope, steps and headroom are separate checks; a class label alone does not prove access.

Compare the route with exact machine data

Enter site measurements, then copy the exact transport/configuration figures from the manufacturer manual or hire supplier. Blank machine fields deliberately produce no pass-style result.

Result

How to use this result

Measure the clear opening after hinges, handles, posts and projections, not the nominal gate size.
Record the exact model and transport configuration used for every manufacturer or supplier figure.
Treat a zero or negative margin as a prompt for a supplier access assessment, not as permission to squeeze through.

When this hire route becomes relevant

After comparing the exact transport dimensions with the measured route, use this category to ask the supplier for the named machine's current data.

Checks this comparison cannot settle

Unloading space, edge protection, ground bearing and surface protection.
Whether the machine can travel with attachments in the required configuration.
Operator, supplier or manufacturer restrictions that are more conservative than the entered figures.

Mini digger width and access: compare the exact machine data

Mini digger width is configuration-specific. Retractable undercarriages, blades, attachments, canopies or ROPS arrangements can change the transport envelope, and two machines sold under the same weight class need not share dimensions. Use the manual or supplier sheet for the exact named model and configuration; this checker deliberately contains no fixed model or class dimensions.

Gate and path clearance

Measure the smallest clear opening along the whole route. The comparison uses the narrower of the entered gate and path widths, then subtracts the exact machine transport width plus the clearance margin entered for each side. The margin is a planning figure chosen by the user, not a guarantee that the route is workable.

Turning and corner space

A machine that fits through a straight opening may still fail at a corner. Enter the smallest measured corner or turning envelope and compare it with a turning boundary supplied for the exact machine. Overall length, rear swing, blade position and attachment position can all matter, so ask the supplier how its stated figure should be applied to the route.

Slope, steps and thresholds

Enter the steepest route slope and highest obstacle separately. Compare them only with limits or boundaries given by the manufacturer or supplier for travel in the relevant configuration. Wet ground, cross-fall, poor bearing, attachments or a loaded machine can require a more conservative decision than a published maximum.

Headroom

Measure below lintels, branches, scaffolds, cables and temporary works. Compare the lowest clear headroom with the exact transport height plus the overhead margin you choose. Confirm whether any folding or lowering procedure is authorised; do not assume a canopy or protective structure can be altered for access.

What to record before asking for hire

Exact make, model and configuration quoted by the supplier.
Manufacturer manual or supplier sheet name/revision used for width, height and movement boundaries.
Gate, path, corner, slope, step and headroom measurements, including the point where each was taken.
Your side and overhead planning margins and any unresolved unloading or ground-protection issue.

After confirming access, estimate the mini digger hire duration. If the job includes a trench, calculate the entered material assumptions with the trench spoil volume calculator.

This is a dimensional comparison, not an access approval, method statement or stability assessment. The supplier, operator and manufacturer instructions govern the final decision.
