An escalator and moving walk shaft mounting construction and method utilizes a truss, a shaft and a shaft-bearing to hold the shaft in the truss. The shaft bearing has a hub and a socket. The hub is affixed to the truss, while the socket interfits with the hub to hold the shaft. The hub-socket connection can be severed to release the shaft from the hub.

Escalator or moving walk with shaft-bearing and method of mounting and dismounting this escalator

An improved escalator or moving walk construction, head elements are pre-assembled as a sub-assembly which is subsequently mounted on the truss of the escalator. The sub-assembly includes comb plate holders, one on each side, which carry a comb plate. The comb plate holder may have a C-shaped profile and may be reinforced by stiffening ribs so as to be able to bear the weight of the end-curve of a balustrade. By means of supports arranged on the truss, the height of the comb plate carrier can be adjusted to that of the truss. During pre-assembly, and until after final mounting on the truss, the comb plate serves as a connecting element between comb plate holders.

Escalator or moving walk

An escalator or moving walkway includes, divided roller bearings to improve the efficiency of replacement thereof. The roller bearings may be located in the region of the drive axle or deflecting axle of the step chain. The divided roller bearing components can be mounted on the roller bearing axle, and removed therefrom, in radial direction.

Escalator or moving walkway

A lubricating device for an escalator or moving walkway provides a lubricant container connected by way of lines with lubrication points which are arranged at a base plate which forms lateral borders for the escalator/moving walkway step belt or plate belt. Sliding pads are provided at the escalator steps of the step belt or at the plates of the plate belt which project slightly beyond the side edges of the steps or plates and, when sliding past the lubrication points, receive lubricant and subsequently transfer it to the base plate.

Lubricating device for an escalator or a moving walkway

An apparatus for exchanging roller bearings of escalator and moving walkway chainwheel sub-assemblies includes the provision of auxiliary supports to which the chainwheel sub-assembly can be fixed. With removal of axle carriers the central axle becomes accessible, and can be displaced laterally to disengage from one of the roller bearings, which is subsequently removed and replaced. The central axle is then displaced in the opposite direction to allow access to an opposite roller bearing. Auxiliary centering for the axle in an axle cylinder is provided to prevent shifting of the axle within the cylinder when the axle carriers are removed. The steps of fixing the chainwheel sub-assembly to the auxiliary supports and subsequently shifting the axle to free the bearings constitute a method for bearing removal which does not require disassembly of the escalator/walkway conveying run and allows the escalator or walkway to be walked on during the exchange process.

Equipment and method for simplified roller bearing exchange at escalators and moving walkways

A drive for an escalator is installed on one or both sides of the escalator at the lower and/or upper end and comprises one to several identically constructed drive units, which are arranged and distributed about the circumference of a main drive wheel. The drive units can be flange-mounted in either a longitudinal or transverse direction to the direction of travel of the escalator on a common main gear housing which can be identical for the support of one or more drive units. The operation of the motors of the drive units are controlled by way of a common frequency-setting device. A control and regulating unit processes input data into control and regulating data for the frequency-setting device, a relay control and optical signals and illumination for the escalator. The individual drive units are switched in or out according to the actual power requirements of the escalator during operation.

Drive for an escalator

A floor cover for use in conjunction with conveying equipment for persons located at an end of an escalator, moving walkway or the like, has one or more cover elements which can be walked on and which flushly close off, relative to the surrounding flooring, the opening of an under-floor space in which operating equipment is typically located. The cover elements can be lifted and laterally displaced to expose the opening for access to the operating equipment. The cover elements are separably joined together at joint locations. A resilient profile member is located at each joint to prevent the generation of noises and to provide a tight seal between the cover elements against penetrating dirt. The cover can be raised, laterally displaced and rotated away from the opening by means of a multi-part hinge. The turned-up cover elements can, with a support device, be retained in a raised position to form an entry barrier for the exposed opening.

Floor covering for conveying equipment for persons

An apparatus for stopping passenger conveyors, such as escalators and moving walkways having at least one comb plate, responds to movement of the comb plate due to an applied force to actuate a safety switch. The apparatus exerts a static trigger force on the comb plate which trigger force has horizontal and vertical components. The comb plate is movable horizontally and vertically against a static trigger force when the applied force exceeds one or both of the horizontal and vertical components. The trigger force is set by a biased trigger spring pivotally mounted on a carrier plate for the comb plate and acting at an adjustable angle relative to the horizontal plane permitting selection of the ratio of the horizontal component to the vertical component. The angular position can be reset manually within a certain angular range through engagement of detent notches on an abutment attached to the comb plate and detent pins connected to the trigger spring.
