摘要： A dock leveler comprising a ramp movable between a lowered position and a raised position, an inflatable member positioned to move the ramp to its raised position upon inflation of the inflatable member, and an inflating device operatively connected with the internal cavity. The inflatable member includes upper and lower portions at least partially defining an internal cavity. An insert member is positioned in the internal cavity for maintaining a volume of gas between the upper and lower portions. Preferably, the insert member functions to maintain the inflatable member in engagement with a downwardly facing surface of the ramp, thereby inhibiting the presence of debris between the inflatable member and the ramp, and further expediting inflation of the inflatable member.

摘要： A dock leveler including a ramp is movable to a raised position by inflation of an inflatable member, such as an air bag assembly. One or more filler members are located within an internal cavity defined by the air bag assembly, to occupy void volume therein. The filler members expedite inflation of the bag assembly when an inflating device is operated to introduce air under pressure into the bag assembly. The filler members also function to maintain the bag assembly in an engaged condition with the underside of the ramp, and to prevent the air bag assembly from fully collapsing in order to prolong bag life.

摘要： A vehicle restraint comprising a base member (e.g., a track), a carriage movably mounted to the base member, and a restraining member (e.g., a pivotable hook) mounted to the carriage and movable between and engaged position and a disengaged position. The restraining member is biased toward the engaged position. The restraining member is biased by a biasing member in the form of a gas spring operatively positioned between the restraining member and the carriage. The restraining member is pivotable, and the restraint further includes a lever interconnected with the restraining member. In this embodiment, the biasing member is interconnected with the lever to bias the restraining member toward an engaged position. The biasing member can be positioned to bias the restraining member toward the disengaged position when the restraining member is in the disengaged position and to bias the restraining member toward the engaged position when the restraining member is in the engaged position.

摘要： A vehicle restraint adapted to be used at a loading dock to restrain a vehicle during loading and unloading operations. The restraint includes a carriage adapted to be mounted to the loading dock, and a restraining member (e.g., a hook) connected to the carriage. The carriage is movable relative to the loading dock between an inoperative position and an operative position that is typically higher than the inoperative position, and is biased towards the operative position when in the operative position. The restraining member is movable relative to the carriage between a restraining position and a nonrestraining position. The restraining member is capable of restraining an ICC bar when in the restraining position, and is biased toward the restraining position independent of the bias of the carriage.

摘要： A support leg system and method for supporting a dock leveler. The support leg system includes a support leg, cam, engaging surface, and counterbalancing apparatus. The method includes moving a support leg to a non-supporting position when the dock leveler ramp is engaged with a vehicle, and moving the support to a supporting position if the dock leveler ramp descends too quickly.

摘要： The dock leveler is adapted to be mounted to a loading dock and includes a ramp, a guard, and a biasing member. The ramp is rotatably coupled to the loading dock and the guard is rotatably coupled to the ramp. The guard is rotated between a raised position that forms a barrier and a lowered position that permits loading equipment to freely pass. The biasing member is coupled to the guard and biases the guard toward the raised position when the guard is in the raised position and biases the guard toward the lowered position when the guard is in the lowered position.

摘要： A dock leveler including a ramp having a rear edge movably interconnected with a loading dock, an intermediate member movable relative to the ramp, and an inflatable assembly positioned to cause relative movement between the ramp and the intermediate member upon inflation of the inflatable assembly, thereby resulting in movement of the ramp. The intermediate member is movably mounted to a pit floor, a support structure, or the ramp. A roller member is mounted to an end of the intermediate member. The inflatable assembly can be operatively associated with a vacuum device to allow for selective removal of gas from the inflatable assembly. Alternatively, a hydraulic assembly and a support frame may replace the inflatable assembly and intermediate member. The dock leveler includes hook-type bracket members and mounting bores to accommodate either powering arrangement.

摘要： A lip lifting mechanism for the pivotable lip of a dock leveler moves the lip to an operative extended position as the ramp of the dock leveler is moved from a raised position toward a lowered position. The lip lifting mechanism includes a push bar, a lifting rod, a lug engageable with the lip through the lifting rod, and a link arrangement to which the lifting rod is pivotably mounted, with the push bar being engageable with the link arrangement upon downward movement of the ramp. The push bar moves the link arrangement and the lifting rod into an over-center toggle position to extend the lip. Engagement of the lip with the bed of a truck results in the link arrangement and the lifting rod being moved to an under-center release position, so as to enable the lip to fall to a pendant position when the truck moves away from the dock. The invention contemplates a unique construction of the engagement structure between the push bar and the link arrangement for increasing the force applied to the lifting rod by the push bar, and a trip structure for ensuring that the lip is always returned to its pendant position when the dock leveler is in a lowered, storage position.
摘要翻译：当船坞调平机的斜坡从升高位置向下降位置移动时，用于船坞调平器的可枢转唇缘的唇部提升机构将唇缘移动到可操作的延伸位置。唇部提升机构包括推杆，提升杆，通过提升杆与唇缘接合的凸耳，以及连杆装置，提升杆可枢转地安装在该连杆装置上，推杆可在向下运动时与连杆装置接合的坡道。推杆将连杆装置和提升杆移动到超中心的肘节位置以延伸唇缘。使唇部与卡车床的接合导致连杆装置和提升杆移动到中心下部的释放位置，以便当卡车从码头移开时能使唇部落到悬挂位置。本发明考虑到推杆和连杆装置之间的接合结构的独特构造，用于增加由推杆施加到提升杆上的力，以及跳闸结构，用于确保当唇形件总是返回到其悬挂位置时，码头调平器处于较低的储存位置。
