Lifting innovation
US crane rental company, BiggeCrane andRigging,was oneof
the first customers for a VPC-equippedMLC650. Ryan Parker,
marketing manager for Bigge, said, “We believe this crawler
crane might set the new standard with its upgrades to weight
balance, line pull and capacity.”
The company said it planned to use the
crane for lifts in the petrochemical, power and
infrastructure constructionfields.
Meanwhile, All Erection & Crane Rental in
the US ordered 10 new 300 tonne capacity
ManitowocMLC300 crawler cranes last year, and
was enthusiastic about theVPC feature.
All Erection&Crane Rental presidentMichael
Liptak said, “This is our bread-and-butter
capacity range, and being able to create savings
for our customers here, at this capacity, is part of
why customers choose All. Without hyperbole
I tell you that this technology will change the
crawler category.”
Rick Mikut, All Erection & Crane Rental
crawler crane division manager added, “We can
reduce the number of required mats by half.
That’sUS$1,000 in savings permonth, and that’s
saying nothing of the reduced counterweight
loads and the savings realised by reducing the
required job site prep area.”
Another interesting innovationfromManitowoc
over the last year has been the introduction of a
synthetic rope designed specifically for cranes,
developed in partnership with synthetic rope
specialist Samson.
Manitowoc says the KZ100 hoist rope is 80%
lighter than wire rope and is ‘torque neutral’
whichmeans loads will not spinwhen lifted.The
company also says this type of rope is easier to
handle and install, as it is less prone to kinking,
bird caging (separation of strands) and damage
from other types of cable-spooling issues.
The rope is also said to be corrosion resistant
anddoes not require lubrication.
Before introducing theKZ100 rope,Manitowoc
and Samson carried out field and lab tests to
check its reliability which used some 7,500 m
of rope in 14,000 cycles of testing. Manitowoc
also said durability tests were carried out by two
independent companies.
Terex’s Explorer 5500 is one of
several new all-terrain cranes to
adopt a single engine design.
Terex’s BoomBuster is a kit for the company’s
CC 8800-1 crawler craneswhich increases
lifting capacity by strengthening the boom
against lateral forces.
