AS 3856.1:2021 – Hoists and ramps for people with disabilities-Vehicle mounted Part 1: Product requirements.
(g) Handrails shall be provided and shall be capable of withstanding a force of 450 N applied at any position and in any direction without showing any permanent deformation.
(h) Removable handralLs shall be securely fixed to the platform when the hoist is fully deployed. Guardrails shall not become detached when subjected to a force of 450 N applied at any position and in any direction.
(i) Where handrails are detachable, a suitable means of storing them shall be provided.
NOTE 2 The size of the platform will depend on the application. The hoist may be for a private operator or it may he for a specific group or for use by the public in public transport. There will also be limitations imposed by the motor vehicle to which the hoist is fitted,
NOTE 3 The platform Length will be limited by the vehicle design, The dear length is measured between the outer roll stop and the inner roll stop when the platform is deployed. The minimum length should be 1 000 mm but this would need to be longer if the platlorm was designed to allow for an attendant. The minimum length of a hoist platform required for public transport is 1 300 mm.
NOTE 4 The clear width is measured between the Inside of the edge carriers when the platform is deployed. The minimum width should be 7641 mm. however the recommended minimum clear width is 780 mm. The minimum width ota hoist platform required For public transport is 800 mm.
NOTE S Consideration should he given to the maximum head room allowance where access will be required by ambulant persons.
5.2 Performance requirements
5.2.1 Uncontrolled descent under gravity
When tested in accordance with Appendix A. the platform shall not descend at a rate of more than 0,3 m/s.
5.2.2 Deflection
When tested in accordance with Appendix B, any deflection of the platform under test load shall not change the inclination of any part of the platform by more than 3 degrees.
5.2.3 Static strength
When the appliance is tested In accordance with Appendix C, there shall be no permanent deformation of any part of the appliance, no fracture shall have occurred in any part of the appliance, and the appliance shall operate without failure.
5.2.4 Speed
When the appliance is tested in accordance with Appendix D. the speed of the platform shall be not more than 0.15 m/s.
5.2.5 Acceleration
When the appliance is tested in accordance with Appendix D. any horizontal and vertical accelerations of the platform shall be not more than 0.3 m/s2.
5.2.6 Durability
When tested in accordance with Appendix 0 the appliance shall not fail.
6 TypeCappilances
6.1 Design and construction requirements
TS’pe C appliances shall conform to the following:
(a) The choice of materials used in the construction of the hoist shall be suited to the intended area of use.
NOTE It is recommended that polymeric materials are not used due to degradation associated with ultraviolet light.
(b) All load-bearing fasteners shall be either sell-locking or fitted with a locking device to prevent inadvertent detachment.
(c) It shall not be possible to assemble the hoist in a manner which affects the overall safety of the unit. If the lifting device incorporates a mast, it shall be sa located in relation to its base that It can only be assembled or adjusted in the correct safe working position.
(d) A connection point shall be so designed that the body-support unit shall not become inadvertently detached.
(e) Where necessary, all precautions shall be taken e.g. by the fitting of a safety devices(s)1 to protect the lifted person from inadvertently falling off/from the body-support unit,
6.2 Performance requirements
6.2.1 StatIc Strength
The requirements of Clause 5.2.3 shall apply.
Care should be taken to ensure the installation of a type C appliance does not compromise the vehicle’s compliance with ADR 42. Portable variants in Lhe worst-case load scenario shall have a load at least 1.5 times the manufacturer’s rated capacity.
6.2.2 DurabilIty
The requirements of Clause 5.2.6 shall apply.
7 Type D and E appliances
7.1 General
Ramps shall conform to the following:
(a) The surface of the ramp shall have a slip-resistant finish when tested in accordance with AS 3696.13.
(b) A ramp shall have edge barriers.
NOTE The recommended minimum height for edge barriers is 75mm.
(c) When deployed, the gradient of a ramp shall be no steeper than 1 in 6.
