Lifting, lowering and levelling buildings

Lifting, lowering and levelling buildings

Commissioned by: House Lifters / Meccanico
Location: New Zealand

Lifting, lowering and leveling earthquake-damaged properties. Commissioned by House Lifters / Meccanico, Holmatro supplied a 2,000 ton Synchronized Positioning System.

Situation

House Lifters lift and re-level hundreds of earthquake-damaged properties in Christchurch and Canterbury including; businesses, homes, Heritage buildings, churches.

Challenge

To ensure safe and controlled lifting, lowering and levelling of heavy properties, House Lifters was looking for a flexible, easy to handle and extremely accurate synchronous lifting system. Because complex lifting proceedures also often require ‘tilting’, this feature was a 'must-have' in the new system.

Solution

Lifting, lowering and levelling buildings

Holmatro developed a 2,000 ton synchronized positioning system with the option to determine the center of gravity (COG) and be able to weigh the load if necessary. The system is equipped with 6 double-acting pump units, each with 4 individual oil flows for all the 24 lifting points. Due to the modular set up of the system, the pump units can be placed around the object and then connected together. Thanks to this set up, the distance from the pumps to the lifting points can be kept equal and limited to the bare minimum. This results in much more stable lifting and lowering with significantly less vibration. The modular set up also provides huge flexibility; the system is easy to control and move around, without the need for any additional equipment such as a crane or fork lift: A major benefit on job sites where access is difficult and cranes cannot get access.

Lifting, lowering and levelling buildings

The pumps are linked together by means of a data cable that is connected to a portable HMI (Human Machine Interface) complete with touchscreen. The software on the system allows the user to set the exact parameters  required to execute a complex lift. Should something fall outside of the given parameters (for instance an unexpected shift in weight) the system automatically stops the lift, so that the user can safely check and secure the object before recommencing the lift.

Due to the double-acting cylinders, the user has maximum control both on the lifting and the lowering action as gravity is not relied upon to lower the load.

Holmatro’s synchronized positioning system can easily be up-scaled by adding more pumps and cylinders, giving it an almost unlimited capacity in terms of lifting, lowering, levelling and weighing.
