HOST APPARATUS

摘要

The invention relates to a hoist apparatus (10) including at least one of a three-part double reeved bottom block (56) 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 (46) beyond a desired position, a hybrid gear box (62) adapted for use on two different categories and/or types of hoist apparatuses through the use of an adapter plate (214) that permits coupling of the gearbox (62) to the hoist drum (46) of the hoist apparatus in a plurality of configurations and an external ring gear (218) that results in a second output torque and speed of the gearbox, a self-lubricating load braking assembly (400) having lubrication inlet holes (460) and lubrication outlet holes (464) for pumping lubrication into and out of the load brake assembly (400), a gearbox (62a)for use on the hoist apparatus (10) including a two-stage high gear ratio gear set (470) and a load brake assembly (400), a controller (500) configured to acquire operational data representative of the hoist apparatus (10) and generate an output indicative of a remaining useful life of the hoist apparatus, and an inverter controller (1080) configured to control verify load integrity and prevent possible load loss without the use of a load brake assembly (400) and/or an encoder or similar feedback device.
