Abstract

Abstract Since many years hook lift/hooklift devices are used for the transport and handling of containers/bins, trays etc. in a lot of countries. Although, several countries have already standardized dimensions - concerning the distances between the rails or dimensions of the skids -such as Germany with the EN DIN 30722.1 = 1,060 mm - contai ners/bins in Australia have often different (customized) measurements (e.g. 660 mm or 880 mm width). Therefore, the loads with those measurements cannot be properly secured with the standardized hook lift module's lockings, because all commonly used lockings are designed for a width of 1,060 mm. In order to remedy this inadequate situation by transporting/handling of such loads, the - in the fol lowing - described innovation was developed in order to enable securing of containers/bins etc. with all widths during transport by using the variable locking device: A hook lift/hooklift module with variable locking device(s) - mounted onto trucks/lorries - for loading, unloading, dumping/tilting and transport of payload - such as hook lift containers/bins, platforms, trays, tank containers and other load, which is handled with a hook lift/hooklift device - with varied widths of the load's subframe rails/skid. The hook lift/hooklift module has a subframe structure, on which infini tely variable locking device(s) and/or graded locking device(s) is/are mounted onto the front and/or rear side and/or onto the front and rear side in order to secure all the loads, which can be handled with such hook lift/hooklift device. The locking devices of the hook lift/hooklift module may have hydraulically operated drive and/or pneumatically operated drive and/or electrically operated drive - to go by the carrier truck/lorry. Each locking device has one and/or more clamp(s) and/or one or more plunger(s) on one and/or both sides (left and/or right side) external and/or internal in order to secure the load and to avoid slipping/fall down of the load during transport and/or handling after the locking device is activa ted/closed by the operator/ driver. The locking device(s) has/have hydraulic cylinder(s), which is provi ded with hydraulic oil by the hook lift's/hooklift's hydraulic oil tank and/or by a separated hydraulic system, for adjusting the clamp(s) and/or plunger(s) to the needed/suitable width of the actual payload's subframe rails/skid. The hydraulic cylinder(s) activate(s) also the closing/opening of the clamp(s) and/ or plunger(s) in order to enable loading/unloading of the actual load by the hook lift/hooklift arm. The hook lift/hooklift device may also have a rear roller assembly with separated rear rollers and/or with a continuous rear roller in order to ensure loading/unloading of the actual load of varied widths with one and the same hook lift/hooklift device. The hook lift/hooklift device may also be equipped with lateral supports with/without roller bearing(s) in order to ensure a smooth and silent loading/unloading and safe transport/ handling of outsized loads. The lateral supports may also be equipped with mechanical locking devices such as twist locks in order to secure the actual load during transport and/or handling. v44

Description

Description of the Drawings Fig. 1 shows an improved hook lift/hooklift module with exemplary, adjustable locking devices (2),(3). On the front side the adjustable locking is shown with external clamps (2) and on the rear side the adjustable locking is shown with internal and external clamps (3) - equipped to the hook lift's basic frame/structure (1) with hydraulically operated lift arm (4). Fig. 2 shows a detailed view of the rear part (A) of the hook lift's basic frame/structure (1) with an exemplary, adjustable, rear locking device with internal and external clamps (2) and separated rear roll assembly (3). Fig. 3 shows a detailed view (B) of the left advance section of the hook lift's basic frame/structure (1) with an exemplary, adjustable, front locking device with an external clamp (2) in an inner securing position. Fig. 4 shows a detailed view (C) of the right advance section of the hook lift's basic frame/structure (1) with an exemplary, adjustable, front locking device with an external clamp (2) in an outer securing position, which is achieved by extending the bracket (3) with the connected clamp (2) to the proper width - in order to secure loads of all widths of rails and skids. Fig. 5 shows a schematic, sectional view of an external locking device (1) in the "Open-Position" (2) and "Closed-Position" (3). Fig. 6 shows a schematic, sectional view of an internal locking device (1) in the "Open-Position" (2) and "Closed-Position" (3). Fig. 7 shows a schematic, top view of an internal locking device (1) and of an external locking device (2). Fig. 8 shows a schematic, sectional view of an internal locking device (1) and of an external locking device (2) in the "Open-Position" and "Closed-Position" and with a hydraulic cylinder (3). Fig. 9 shows a side view of the hook lift's basic frame/structure (1) with an exemplary, adjustable, rear locking device (2) with internal and external clamps and with exemplary, adjustable, front locking (3) with external clamps and separated rear roll assembly (4) and an exemplary rail (5) of a potential load on the hook lift module. Fig. 10 shows a top view of the hook lift's basic frame/structure (1) with an exemplary, adjustable, rear locking device (2) with internal and external clamps and with exemplary, adjustable, front locking (3) in an inner securing position with retracted bracket (4) with connected, external clamp. An outer securing position of an exemplary, adjustable, front locking (5) is shown by the extended bracket (6) with the connected clamp (7) to the - in each case - proper width - in order to ensure securing loads of varied widths of rails and skids. A separated rear roll assembly (8) and an exemplary rail (9) of a potential load on the hook lift module is also shown on Fig. 10.
