Access device

Abstract

An access system (10) for earthmoving equipment to allow a person to move from ground level to an elevated position, said access system having an access means (20) mounted to the earthmoving equipment via a pivot, and a retraction mechanism (50) therefor, said pivot allowing the access means to be retracted through a compound angle from a downwardly and outwardly deployed position to a retracted position generally adjacent and aligned beside the vehicle, the access means may be collapsible, such as with steps (30) pivotably mounted to the sides of the access means via secondary pivots (62).

Description

field of invention [0001] The present invention relates to access devices for earthmoving equipment, in particular to a movable or retractable access device, such as a ladder or a ladder. Background technique [0002] Most earthmoving equipment vehicles such as bulldozers typically include a chassis, various front mounted blades, a protective cockpit, a hatch and an access port or access system. The chassis includes all the mechanical components that form the structural framework of the earthmoving equipment vehicle. Driver operates earthmoving equipment vehicle in protective cockpit. The hatch is located at the rear of the cockpit and usually houses many of the important control units of the earthmoving equipment vehicle such as hydraulic controls, hydraulic pumps, fuse boxes, circuit breakers, etc. The access port or access device is configured to provide access between the ground and the cab. A walkway is provided around the cab area for operator access to the hatch at...
