Mchale has introduced a new bale wrapper, the 991 High Speed, that is said to be able to deliver 50% more output than previous machines.
Sales manager John Biggins said that in the past few years contractors had been asking for a higher-output bale wrapper.
“This demand has come about due to baler output increasing and also the move by some contractors to wrapping bales with six layers instead of four,” he said. “We have tested the 991 High Speed against the 991BE (a machine that is recognised in the market place as having an output of 60 bales/hr). For the test we made sure that oil flow and table rotations were the same, and what we found was the 991 High Speed could wrap three bales in the time it took the 991BE to wrap two.”
The 991 High Speed features two 750mm aluminium dispensers that maintain a consistent stretch to maximises film usage. The dispenser units consist of two aluminium rollers that are geared to each other with robust steel gears of different ratios. The dispensers are stepped so that there is an overlap where the two sheets of plastic come together.
The lift arm can be activated with the press of a button; this will load the bale and return the lift arm to a position that is clear of the table before the lift arm starts.
The round bale wrapping table on the 991 High Speed bale wrapper is constructed of four heavy-duty belts that ensure smooth and even bale rotation, even when dealing with loose or asymmetric bales.
A smooth wrapping seal is guaranteed as the machine delivers a 50% overlap. Shear-bolt protection ensures that asymmetric shaped bales do not damage the machines gearbox or drive line.
The McHale hydraulically operated cut and tie system cuts and holds the film in position ready top wrap the next bale. This time saving device eliminates the need to manually reattach the film. The McHale cut and tie is designed in such a way that as it gathers the plastic to one point before it is cut, it pulls the plastic against the side of the bale so that tail are minimised from both rolls.
Film loading is made easy on the machine with the McHale lock and load system. When the operator removes the core of the empty film roll, the top roller locks in the open position, when the new roll is loaded the operator simply pulls the cord at which point the top roller is released and locks the roll in position.
The uniquely designed McHale Patented Bale Damper system is probably one of the most important features of the McHale 991 High Speed bale wrapper. The bale damper system will gently lower the bale to the ground and at the same time eliminate the stress on the chassis of the machine.
When the rotating table stops and is raised to the tip position, the heavy-duty damper raises to cradle the bale, while the second arm is lowered automatically to the ground. This allows the heaviest of bales to be gently lowered eliminating any damage.
The cab mounted control console is the link to this high-output machine. It keeps the operator up to date on key machine operations through a graphic display.
From the control console, the operator can select: the auto bale load function; the auto bale tip function; the number of film layers to be applied to the bale; and a single-roll wrapping mode. And while the 991 High Speed is fully automatic in operation, the operator can select various options depending on ground conditions.
The 991 High Speed is fitted with film-break sensors that monitor the plastic as it is applied to the bale. Should one roll of plastic break or run out, the machine will detect this and notify the operator through the control box and automatically switch to single-dispenser mode. The machine then continues to wrap the bale, but slows bale rotation and increases the number of table rotations to compensate for the broken roll. This ensures that bales are always wrapped correctly.
