Features
The Metro 31 is the most versatile boom in the world. Advanced
boom design includes the lowest unfolding height in its class
with a five section Z-fold boom. Features extendable rear outriggers
and "X" style extendable front outriggers that span
6.2m for fast set-up, stability and easy pump placement in narrow
areas.

Boom
State of the art Z-fold five section boom features exclusive
patented 5th section "Spinner" that allows continuos
360 degree rotation in either direction, Unparalelled performance
ensures there is no position you cannot reach with the 5th section.
This boom is ideal for applications when passing through small
openings or reaching into, or getting out of, difficult positions.

Pump
Modular unit features a unique computer-designed S-valve in
wear resistant casting. A compression loaded wear ring mounted
between the wear plate and the S-valve provides a positive seal
for low slump, low cement ratio and lightweight aggregate pumping.
Automatic wear ring compensation eliminates the need for constant
adjustment. Concrete hopper features a cylinder shaped bottom
and extra wide opening for quick clean out discharge. Reversible
wear plates and hard-chromed concrete cylinders ensure long
life and minimal maintenance. Wear resistant replaceable spiral
agitator blades bolt into place for easy repair. Concrete hopper
is also removable to simplify maintenance.
Automatic-sequence control system features full hydraulic control
by direct pilot, eliminating accumulators and unneccessary electronic
controls. Stroke adjustment for every pump cycle is automatic
and constant, |
