An adjustable platform system configured in or attached to a ladder having a moveable or adjustable platform assembly operatively coupled thereto. An adjustment mechanism is operatively connected to the first and second arm members and the platform member, whereby the platform member is selectively movable along a length of the ladder legs or the first and second arm members via the adjustment mechanism.

A jack lift device for lifting and positioning loads includes a tube, a pipe and a hoist. The tube is configured to insert into a hole in a top of a step ladder. The tube is configured to couple to the step ladder so that the tube is positioned substantially vertically. The pipe is complementary to and selectively slidably positionable within the tube. A plate is coupled to and extends perpendicularly from an upper end of the pipe. A hoist is coupled to the tube and operationally coupled to the pipe. The plate is configured to position a load, such as a metal conduit. The hoist is positioned to selectively compel the pipe vertically through the tube so that the load that is positioned on the plate is positioned at a desired height, such as proximate to a joist to which the metal conduit is to be is coupled.

According to an embodiment, a ladder includes a side rail having top and bottom ends; at least two rungs connected to the side rail; a top cap disposed near the top end of the side rail; and a foot protrusion mounted to the top cap and shaped to physically engage a battery pack slot of a power tool, such that attaching the power tool to the foot protrusion secures the power tool to the top cap. According to another embodiment, a power tool storage apparatus, includes a base member shaped to be secured to a storage surface; and a tool engaging portion extending from the base member. The tool engaging portion is shaped to physically engage a battery pack slot of a power tool, such that attaching the power tool to the tool engaging portion secures the power tool to the storage surface. Other embodiments are also disclosed.

An automated system for raising and lowering a person to various desired levels and enables the person to more comfortably and safely perform activities and tasks that require them to be at an elevated position relative to floor or ground surface. This system can comprise a lift platform attached to a series of vertical rails. The present invention has the capability to enable a user to remotely control vertical movements of the standing platform and the horizontal movement of this invention. This invention can enable a user to remotely control vertical movements of the standing platform and the horizontal movement of this invention. A remote control device facilitates these control movements. This invention can also move laterally across a horizontal surface and can detect obstruction during these movements. As an obstruction is detected, this device has the capability to stop movement to ensure safety of a user.

A lift system comprising an elongated rack and a roller pinion drive system. A preferred version has two parallel rack with plurality of rungs extending horizontally between the racks to form a ladder. A plurality of spaced apart mounting brackets are configured for affixing the ladder vertically to a stationary member, the stationary member not forming part of the invention. In this version, a drive unit retained within a carriage is mounted in proximity to the racks. The drive unit interacts with the racks to move the carriage upwardly and downwardly along the racks. A speed limiter is also disclosed that can be retained within the carriage below the drive unit and mounted in proximity to one of the racks. The speed limiter interacts with the rack to produce a breaking action if the drive unit fails, preventing the carriage to drop down quickly. Single rack and inclined rack versions are disclosed as alternatives.

A modular lifting apparatus includes a vehicle body assembly and a drive control assembly. The vehicle body assembly includes a vehicle body and a pedal component, and the pedal component is connected to the vehicle body. The drive control assembly is disposed on the vehicle body, and includes a control component, a drive component and an auxiliary guide component. The control component is connected to the drive component. The drive component and the auxiliary guide component are used to cooperate with a guide body to allow the vehicle body to move in an extension direction of the guide body.

The present disclosure provides a ladder which selectively allows or prevents user access to the ladder steps, such that the ladder can only be climbed when such access is allowed. For example, the ladder may only selectively allow ingress into a bathing enclosure, e.g., when operated by an adult, but may allow egress from the bathing enclosure by any user. The ladder includes an elevator that is movable between a safety configuration, in which ingress is prevented or inhibited but egress is permitted, and a ladder configuration, in which both ingress and egress are permitted.
