OPERATION

Alarm - Figure 1

The alarm helps to protect frozen food and to save energy.

The audible warning device is turned OFF by pressing the Alarm Button (Fig. 1, 5).

It turns OFF automatically as soon as the temperature is low enough.

Audible door alarm

This sounds when the door has been left open for longer than about 60 seconds.

The sound switch-OFF function is active as long as the door is left open.

The alarm automatically switches back to standby when the door is shut.

Audible / visual temperature alarm

It always sounds if the freezer temperature is not low enough (dependent on the temperature setting).

The temperature display flashes at the same time. This can be caused by:

-warm, fresh food being placed in the freezer,

-too much warm air from the outside entering when rearranging or removing frozen food.

The temperature display will continue to “flash” until the cause of the alarm has been rectified. It will then stop flashing and light up continually. The alarm is now automatically reset.

Power Failure / FrostControl

Display - Figure 1

If appears in the display, this means the freezer temperature has risen too high

during the last few hours or days due to a power failure.

Once the power is back on, the appliance will continue to operate at the most recent temperature setting.

If you press the Alarm Button (Fig. 1, 5) while the display is reading , the highest temperature registered during the power failure will be displayed.

Check the quality of the food in case it has become too warm or even defrosted.

The highest temperature will appear for approximately one minute. After that, the actual temperature in the freezer will reappear.

The in the display will disappear once the Alarm Button is pressed again.

A delight in freshness

HC1050, HC1001 specifications

The Liebherr HC1001 and HC1050 represent a significant advancement in heavy construction equipment, particularly in the realm of crawler cranes. These machines are engineered to deliver exceptional performance, reliability, and operational efficiency, ensuring they meet the diverse needs of modern construction sites.

The Liebherr HC1001 is characterized by its robust lifting capacity and compact design, making it an ideal choice for applications in tight spaces where maneuverability is crucial. With a maximum lifting capacity of 100 tons, the HC1001 can handle a variety of loads with ease. This crane is equipped with a powerful diesel engine that provides ample power for lifting and hoisting, yet maintains fuel efficiency. Its optimized hydraulic system enhances performance while reducing operational costs.

The HC1050, on the other hand, steps up the game with a maximum lifting capacity of 120 tons. This model features innovative technologies that further improve productivity and safety on job sites. The HC1050 incorporates a state-of-the-art control system that provides real-time data to the operator, allowing for precise maneuvering and load management, reducing the likelihood of accidents during operation.

Both models feature Liebherr's advanced Luffing Jib technology, which enables them to work at variable angles, adjusting to different site requirements without compromising stability. This feature is particularly advantageous in urban construction settings where space is limited. The luffing jib also allows for higher lift heights and an extended reach, making these cranes versatile tools for a wide range of construction tasks.

Safety is paramount in Liebherr’s crane designs, and both the HC1001 and HC1050 come equipped with multiple fail-safes and monitoring systems. These systems provide alerts for overloads and operational limits, ensuring that operators can work confidently within designated safety parameters.

In terms of maintenance, Liebherr has designed these cranes with easy access to key components, simplifying routine inspections and servicing. This focus on maintenance means that downtime is minimized, allowing for continued productivity on job sites.

In conclusion, the Liebherr HC1001 and HC1050 crawler cranes combine impressive lifting capabilities with innovative technologies, making them suitable choices for modern construction challenges. Their advanced features, safety systems, and ease of maintenance position them as reliable heavy equipment for contractors aiming to enhance efficiency and safety in their operations. Whether for urban projects or expansive construction sites, Liebherr's commitment to quality and performance shines through in these models.
