The McHale 991 BJS is a servo joystick machine which uses low pressure hydraulics to provide a smooth controlled transition between functions.This system is often favoured by high-end users as it allows full control over the functions of the machine. Each wrapping function is controlled through a sequence of joystick movements. The servo joystick allows the operator to control the following functions:
|Lift Arm||Wrapping Table|
|Cut & Hold||Bale Tip|
The servo operated system on the 991 BJS uses low-pressure hydraulics, which provides a similar feel to the joystick used in telescopic loaders. On the 991 BJS the wizard control console allows the operator to select the following:
|Set the number of layers to be applied||Set and monitor the revolutions per minute of the bale wrapping table||Store two job totals|
|Single Lever Servo Joystick Control||750mm Film Dispenser||Hydraulically Operated Cut & Hold|
|Capacity to carry 7 rolls of film (6&1)||Bale Support Bobbins||3.5 Metre Cables (Other lengths available)|
|Patented Ground Supported Damper||Shear Bolt Protection System||Quick Fit Film Dispensers|
The patented bale damper system gently lowers the bale to the ground while eliminating any stress on the chassis of the machine.
The 991 BC and BJS lift arms are operated manually. On the 991 BE and High-Speed, the auto lift function places the bale on the wrapping table automatically.
The 991 B range can carry 7 rolls of film:
1 roll (dispenser) + 6 rolls (film storage)
An optional side tip is available on all trailed machines to place bales on their ends after wrapping is complete.
At the end of the wrapping cycle, the hydraulically operated cut & hold system cuts and holds the film in position ready to wrap the next bale.
Automatic film break sensors monitor the plastic as it leaves the dispenser rollers. If plastic breaks or runs out, the machine will notify the operator via the control console.
The McHale lock and load system makes film loading quick and easy by locking the dispenser bobbin up when unloading and locking it back down by simply pulling the cable.
A Shear Bolt protects the gearbox when wrapping poorly shaped bales. All machines are now driven by a heavier gearbox than previous models.
The single joystick servo controller on the 991 BJS uses low-pressure hydraulics, similar to telescopic loader controllers, to smoothly transition between the four functions: lift arm, wrapping table, cut & hold and bale tip.
