LIEBHERR MK 88-4.1 MK Mobile Construction Crane

The mobile construction crane MK 88-4.1

MK mobile construction cranes from Liebherr stand out due to the facts that they can be fully operated by only one person, that they have small space requirements and can operate with interfering edges: The vertical tower allows for Liebherr mobile construction cranes to be erected and operated directly at the building. Also the MK cranes are run with zero emission due to electricity from the site – or self-sufficient with its economical diesel generator set.

With its features the MK 88-4.1 brings all best premises for operations with a high demand on flexibility.

Locally emission-free and operation with only 32 Ampere: Even with low connected voltage the crane works with high load performance
Load-Plus: Up to 10% more load capacity is possible because of the intelligent control system of the MK 88-4.1
Additional ballast: with two more tonnes of ballast the crane rises to the next performance level
Comfortable elevating operator‘s cab: The infinitely height-adjustable elevating operators’ cab provides an excellent view due to its large glass surfaces.

The scale model of the MK 88-4.1 mobile construction crane

We have incorporated our many years of model crane making experience into this MK 88-4.1 model. We also felt it was important to include the small, finer details in this model.

The ballast concept: Ballast your model just as the original
Focus on details: We built the model as detailed as possible – so that you don‘t miss a thing
Proven design: after the great success of the predecessor we hold on to the basic design.

General recommendations for rigging up this model

Please study the manual before you start building up the model and take your time.
Make it step by step, carefully and slowly
We recommend to have a second person to assist, because some of the points are not easy to handle
Please try to guide the wire with your fingers while winding it up to a winch. It will help to avoid that it gets jammed aside of a winch.
Please don’t put too much force on parts of the boom while folding or unfolding. This might cause damage on the small and filigree parts

Building instructions

Place the MK 88 model crane on a flat surface and draw out the four outriggers. Adjust the strut plates in such a way that the crane stands securely. Place the supporting plates underneath the supports.
Raise the tower by hand. Using the lock pin (8) provided, pin the tower at the tower foot.
Extend the tower fully and pin it with the tower locking element (9) provided.
Take off the clips which are wound around the guy ropes to secure it and suspend the pivot point guying in place.
Deploy the jib:In order for the jib to be deployed fully, always slack off the jib retaining rope from the erecting winch in the tower. Alternately give in the rope so that the front boom folds out.
Threading the hoist rope: Unwind enough hoist rope to allow you to guide it over the roller on the tower. Then guide the rope through the trolley, thread on the hook, and tie the end to the jib head. Hang the Liebherr flag on the hook.
Fitting the elevating operator‘s cab and upper guiding rail to the tower: Attach the cab guiding rail (19) to the side of the tower and push the cabin up. Unwind rope from the winch and guide the end through the eyelet on the cab roof and tie it in place.
Attach the exterior mirrors to the right and left sides of the driver’s cabin. The tool carrier is fitted on the back. Place the strut plates in the stowage box provided. An additional ballast can be fitted to your model. Secure the cover to the slewing platform.
Add the handrails to the upper structure. Click the signs into the boom.
