A safety latch system includes a mount, a pawl member, a ratchet member, and a release assembly. The mount is mountable on a housing of a piston. The pawl member is coupled to the mount. The pawl member includes a pawl. The ratchet member has a first sidewall that includes a first connecting portion that is connectable to an end portion of a piston rod of the piston. The first sidewall includes a teeth portion, which is configured to engage with the pawl. The release assembly is configured to provide an engaged state between the pawl member and the ratchet member. The release assembly is also configured to provide a disengaged state between the pawl member and the ratchet member. When in the engaged state, the pawl member is engaged with the ratchet member such that the safety latch system is configured to provide (i) an unlocked state in which the ratchet member is movable relative to the pawl member as the piston rod advances outward from the housing and (ii) a locked state in which the pawl member is configured to lock into a depression between adjacent teeth of the ratchet member to stop the piston rod from moving towards the housing. When in the disengaged state, the pawl member is disengaged from the ratchet member to permit the piston rod to advance outward from the housing and permit the piston rod to retract towards the housing.

There is huge demand for automation in manufacturing, logistics, postal, distribution centers, ecommerce, retail. Typical scissor lift designs can carry large payload but are larger in size. There is a need for a compact fork with more payload carrying capacity. The dual side actuated scissor fork type lift unit is provided. The dual side actuated scissor fork type lift unit includes a top plate, a bottom plate, one or more linear motion (LM) blocks mounted on one or more linear guides, one or more mounting blocks mounted on the one or more LM blocks, and slot on a first end of at least one actuation link is connected to the bottom plate through a pin. The one or more LM blocks is free to slide on the one or more linear guides. The one or more mounting blocks moves along with a motion of the one or more LM blocks.

A light weight plastic liner adapted for receipt over an aerial lift basket. The lift basket mounted on a wheeled boom or scissor lift. The liner includes a floor cover and four side covers for covering an inside and an outside of four sides of a frame on the lift basket. Also, the liner includes a removable door cover for covering a hinged door on the lift basket. Further, the liner includes a bungee cord in a bottom seam of the liner for holding the liner in place on the lift basket.

A material transport cart includes a cart body, a material support body coupled to the cart body, a wheel coupled to the cart body, a motor operable to drive the wheel, and a powered lift assembly. The powered lift assembly is coupled to the cart body and to the material support body. The powered lift assembly is operable to lift the material support body relative to the cart body. A removable battery is electrically coupled to and operable to supply power to both the motor and the powered lift assembly

A robotic item retrieval and transport apparatus includes at least one item retrieval mechanism that is minimally exposed while stored and/or engaged in loading or unloading of objects relative to a deck (e.g., upper surface) thereof. Actuators and at least major portions of one or more movable implements are arranged below the deck. Loading and/or unloading of objects may include lateral sliding, such as by pulling the object while it is supported by an extrinsic support surface. At least substantial portions of an item retrieval mechanism may remain outside a central target area of a deck, to provide a unobstructed or minimally obstructed deck surface for holding objects. The apparatus may be used with at least one movable pallet element. A pallet element and/or a retrievable item may include one or more features detectable by a sensor.

A rail-guided permanent way machine is operated by means of a control device in such a way that at least one state variable (Z) of the permanent way machine is determined in dependence on an operating state, and the at least one state variable is compared to at least one pre-defined limit value (G.sub.W, G.sub.S) for monitoring a derailment safety of the permanent way machine. Thus, the derailment safety of the permanent way machine is determined in accordance with the current operating state and monitored. As a result, the permanent way machine has an expanded operating range and increased performance and thus increased efficiency.

An illustrative example elevator assembly includes a header beam and a first elevator cab supported by the header beam. A plurality of vertically oriented rods extend beneath the first elevator cab. A horizontally oriented mid-beam is coupled to a first one of the rods near a first end of the mid-beam and coupled to a second one of the rods near a second end of the mid-beam. A second elevator cab is situated beneath the first elevator cab and beneath the mid-beam. At least one linear actuator is supported at least partially on the mid-beam. The linear actuator selectively causes vertical movement of the second elevator cab relative to the rods.

An industrial materials handling system including a base member having a loading end with a first senor that detects when a first carriage or second carriage is positioned in a loading/unloading position at the loading end, and an operator end with a second sensor that detects when the first or second carriage is positioned in the loading/unloading position, a controller coupled to the first sensor and second sensor, the first carriage coupled to the base member and a first drive mechanism controlled by the controller to move the first carriage, the loading end, and the operator end, the second carriage coupled to the base member and to a second drive mechanism configured to move the second carriage between the loading end and the operator end under the control of the controller, and a bypass mechanism to move the second carriage between the loading end and the operator end.

The system can include: a container no, a set of sensors 120, and a controller 130. The system can optionally include a robot 140. However, the system 100 can additionally or alternatively include any other suitable set of components. The system functions to monitor and/or maintain a fullness level of a container. The system can additionally or alternatively function to enable robotic picking out of the container (e.g., in a pick-and-place setting). The system can additionally function to maintain candidate objects within reach of the robot's end effector to increase robot uptime while minimizing the extent of the robot's required motion (e.g., in the z-axis).

A lift device includes a base, a platform that is repositionable relative to the base between a fully raised position and a fully lowered position, and a scissor assembly coupling the base to the platform. The scissor assembly includes a scissor layer including a first scissor arm pivotally coupled to a second scissor arm. The first scissor arm is configured to rotate relative to the second scissor arm about a middle axis that extends laterally. A pulley is coupled to the first scissor arm. A tensile member is wrapped around the pulley and coupled to the second scissor arm. An actuator is configured to vary a working length of the tensile member such that the first scissor arm rotates relative to the second scissor arm to move the platform relative to the base.
