A moveable climbing system includes at least one step, a first set of legs, a second set of legs, a first set of wheels operatively connected to the first set of legs, a second set of wheels operatively connected to the second set of legs, and a motor operatively connected to the first set of wheels, configured to rotate the first set of wheels. The climbing system may further include a battery for providing electric supply for the motor. The at least one step may include a rung of a ladder. The at least one step may include a board of a scaffold. The climbing system may further include a motor box housing the electric motor, wherein the motor box may be configured to operatively connect to and disconnect from the at least one step.

A ladder 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 always allows egress from the bathing enclosure by any user. The ladder includes one or more safety blocks moveable between a safety configuration, in which ingress is prevented or inhibited, and a ladder configuration, in which ingress and egress is permitted.

Disclosed herein is a ladder adapted to service the engine of a tractor-trailer truck. The ladder comprises a set of rails having rungs extending between them. A set of rear rails is coupled to the set of rails. A pair of stability beams, terminating in ground contacting feet, extends rearward from the front rail and rear rails on each side of the ladder. A platform, extending rearward from between the set of rails, provides a planar surface allowing a mechanic access to the engine.

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.

A climbing apparatus comprising a base, an upright member extending vertically upwardly from the base and having first and second sides and first and second carriages slidably locatable along the first and second side of the upright member. The apparatus further comprises a foot support associated with each of the first and second carriages, the carriages being rotatable supported by the carriage; and an upright engaging member extending from each foot support to selectably engage the upright when the foot support is rotated to a first orientation and to disengage from the column when the foot support is rotated to a second orientation.
