Posted By Sandy Mc Neill Assistance is required from any fork lift truck guru. I am assessing the lifting capacity of a counter balance fork lift truck at various heights. The trucks rated plate is 1550kgs at 500mm load centre at 5m high. I have the information on load centres and how they affect the lifting capacity. What I dont have is the incremental height capacity. I have contacted the suppliers but they arent being very helpful as they state the only give plated weight and not incremental. Has anyone got a formula or any point of reference that I can use. Many thank Sandy
