Patent number: 10941028Abstract: A safety system for an elevating machine has a base part and an elevating part. The safety system includes sensor assemblies for sensing an electric or magnetic field, which are mounted on different parts of the elevating machine. A data processor is connected to receive sensor signals from the sensor assemblies. A memory stores data relating to numerous patterns of sensor signals associated with the interaction between the elevating machine and an electric or magnetic field. The data processor compares the received sensor signals with the stored data and identifies the positional relationship between the elevating machine and a source of the sensed field.Type: GrantFiled: November 7, 2017Date of Patent: March 9, 2021Assignee: NIFTYLIFT LIMITEDInventors: Thomas Cousins, Steven Redding, Matthew Newman, Charles Cooke, David Tegerdine, Ed Bean

Patent number: 10131195Abstract: A base unit for a vehicle such as a mobile work platform includes a chassis and multiple wheels, at least one of the wheels being mounted on the chassis by a suspension mechanism including a suspension element. The suspension element pivots relative to the chassis about a substantially horizontal pivot axis between an upper position and a lower position, and a stop member engages the suspension element in the upper position to limit its upwards movement. A biasing mechanism exerts a biasing force on the suspension element to urge the suspension element upwards towards the upper position.Type: GrantFiled: October 9, 2013Date of Patent: November 20, 2018Assignee: NIFTYLIFT LIMITEDInventor: Roger Bowden
