摘要： A vehicle leveler includes a first portion which has a leading edge and a trailing edge; the trailing edge is disposed further from the driveway than the leading edge. The vehicle leveler also includes a second portion which has a leading edge and a trailing edge; the leading edge of the second portion is attached to the trailing edge of the first portion and the leading edge of the second portion is disposed further from the driveway than the trailing edge of the second portion. The second portion also includes an extension portion. The vehicle leveler has opposing tapered edge portions contacting the driveway. The opposing tapered edge portions assist a vehicle backing onto the vehicle leveler and also avoid tire damage to the vehicle.

The second portion also includes an extension portion. The vehicle leveler has at least one tension bar connecting the first portion on a proximal end and a lift cylinder on a distal end as well as at least one tension strap. When the vehicle leveler is in an elevated position the tension bar and tension strap keeps the lift cylinder from accidentally shifting.

摘要： A vehicle leveler which includes a first portion with a leading edge and a trailing edge, the trailing edge is disposed further from the driveway than the leading edge. The leveler also includes a second portion with a leading edge and a trailing edge, the leading edge of the second portion is removably attached to the trailing edge of the first portion and the leading edge of the second portion is disposed further from the driveway than the trailing edge of the second portion. The second portion also includes an extension portion. The vehicle leveler has opposing side portions which have a top surface that forms a walkway. A safety barrier with two opposed gates is mounted adjacent to the vehicle leveler. The safety barrier when in an open position acts as a fall protection barrier for a user.

摘要： A modular loading dock that includes a planar ramp member with lower and upper ends. The upper end abuts a preexisting structure and the lower end has a lower edge with a lip, the lip is able to be activated between an extended/engaged position to contact a truck bed. The ramp member has an at least thirteen foot long hydraulically-adjustable ramp section with an integrated dock leveler, the entire length of the ramp section is able to be moved between an upward and downward position. The loading dock also includes a base with top and bottom surfaces, the top surface has an opening to receive a dock leveler into the opening and a dock housing consisting of a modular frame mounted onto the base in sections. The length and adjustability of the planar ramp member allows accommodation of large-sized trailers as well as smaller-in-size delivery trucks and vans.

摘要： A vehicle leveler which includes a first portion with a leading edge and a trailing edge, the trailing edge is disposed further from the driveway than the leading edge. The leveler also includes a second portion with a leading edge and a trailing edge, the leading edge of the second portion is disposed further from the driveway than the trailing edge of the second portion. The vehicle leveler has a door interlock system with at least one pair of photoelectric sensors with a sensor path. When a vehicle is being loaded or unloaded on the vehicle leveler, and at least one of the vehicle doors is opened, the door blocks the sensor path of the photoelectric sensors and prevents the vehicle leveler from lowering or raising.
