Abstract
The invention relates to a hoist apparatus including at least one of a three-part double reeved bottom block that has the same height profile as a two-part bottom block and the same lifting capacity as a three-part bottom block that includes an integral equalizer sheave nest, a device for limiting the rotation of a hoist drum beyond a desired position, a hybrid gear box adapted for use on two different categories and/or types of hoist apparatuses through the use of an adapter plate that permits coupling of the gearbox to the hoist drum of the hoist apparatus in a plurality of configurations and an external ring gear that results in a second output torque and speed of the gearbox, a self-lubricating load braking assembly having lubrication inlet holes and lubrication outlet holes for pumping lubrication into and out of the load brake assembly, a gearbox for use on the hoist apparatus including a two-stage high gear ratio gear set and a load brake assembly, a controller configured to acquire operational data representative of the hoist apparatus and generate an output indicative of a remaining useful life of the hoist apparatus, and an inverter controller configured to control verify load integrity and prevent possible load loss without the use of a load brake assembly and/or an encoder or similar feedback device.
