A drop table can provide optimized lifting operations by employing motor feedback to generate and adapt a lifting strategy that controls lifting parameters. A lifting module may be connected to a first motor and consist of a lifting controller. The first motor can be mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission. A service component can be lowered with the first and second lifting columns by activating the first motor that provides motor feedback. A lifting strategy can be generated in response to the motor feedback and subsequently executed to move the service component to a servicing position.

A lifting and support apparatus having a fully lowered position, a fully extended position and many transitional positions. The lifting and support apparatus includes a base portion with a first leg, a second leg, a third leg and a fourth leg hingedly attached thereto and extending therefrom. The apparatus can also include a first lateral support element that the first and second legs are extending toward and hingedly connected to and a second lateral support element that the third and fourth legs are extending toward and hingedly connected to. The apparatus further includes a lift support portion that has a fifth leg, a sixth leg, a seventh leg and an eighth leg hingedly connected thereto and extending therefrom, the fifth and sixth legs extending to and hingedly connected to the first lateral support element and the seventh and eighth legs extending to and hingedly connected to the second lateral support element. In addition, the apparatus has a drive apparatus and threaded shaft for forcing the first lateral support element and the second lateral support element toward and away from each other, which raises and lowers the lift support portion of the lifting apparatus relative to the base portion. A method of raising or supporting an object with a lifting and support apparatus. The method includes placing the lifting and support apparatus in a desired position relative to the object to be raised and supported. The method also includes actuating the lifting and support apparatus to raise the object to a desired height.

A motorized cart assembly for use in gardening and other outdoor chores includes a first motor that is operationally coupled to a rear axle of a rolling chassis. The first motor is configured to selectively rotate the rear axle to locomote the rolling chassis. A lift module that is coupled to the rolling chassis is configured to selectively raise and lower an item that is positioned upon an upper plate of the lift module. A handle, which is coupled to at least one of the rolling chassis and the upper plate, is configured to be grasped in at least one hand of a user to steer the rolling chassis.

The invention provides a conveying device. The conveying device comprises: a bottom platform, the bottom platform comprising a horizontal guide rail; a hoisting device, the hoisting device being arranged on the bottom platform and capable of moving along the horizontal guide rail of the bottom platform, the hoisting device comprising a base, a hoisting beam and a hoisting mechanism between the base and the hoisting beam, and the hoisting mechanism enabling the hoisting beam to ascend or descend relative to the base, wherein both the base and the hoisting beam extend in a direction parallel to the horizontal guide rail of the bottom platform; and a driving device, the driving device being capable of driving the hoisting device to move along the horizontal guide rail.

A personal lift mechanism and method are disclosed. The personal lift mechanism comprises: a lift having a base structure which pivotally retains a pair of struts which are pivotally coupled with a lift platform; an actuator coupled with at least one of the pair of struts; and a damper coupled with the actuator and operable to dissipate kinetic energy transferred between the lift platform and the actuator. In this way, less mechanically-robust components are required for the lift mechanism, damage to those components and the actuator is less likely, and any load on the lift platform and/or base structure will experience reduced shock due to the energy being instead dissipated within the damper.

The invention provides systems and devices for an easily replaceable bearing system for a gunner stand of a vehicle. The bearing system reduces vibration from the vehicle on the bearings, decreases wear and tear, and reduces audible rattling. The bearing system includes a shuttle having a backplate and protruding geometry. Biased members are removably attached to the protruding geometry and are configured to create tension on rails of a gunner stand, holding the bearing system within the rails.

An integrated lift and dolly is presented which includes a lift mechanism for elevating a vehicle while simultaneously positioning wheels underneath to enable moving the vehicle as the vehicle's wheels are elevated off the ground. The lift assembly can further elevate the supporting frame to remove weight from the wheels of the lift assembly to allow long term storage without relying on the wheels to support the weight of the vehicle. This integrated lift and dolly lifts and supports the vehicle for storage and also facilitates easier service, inspection and cleaning.
