Industrial trucks — Verification of stability — Part 8: Additional stability test for trucks operating in the special condition of stacking with mast tilted forward and load elevated
The ISO 22915 series deals with the safety of industrial trucks, as defined in ISO 5053-1, relative to their stability and the verification of that stability. For the purposes of the ISO 22915 series, industrial trucks are wheeled, self‑propelled or pedestrian‑propelled vehicles, excepting those running on rails. They are either operator‑controlled or driverless and designed to carry, tow, push, lift, stack or tier in racks. This document specifies an additional test for verifying the stability of a truck stacking with mast tilted forward and load in the elevated position. It is applicable to the following types of truck: a) counterbalanced trucks with tiltable masts, as specified in ISO 22915?2; b) reach (retractable mast or forks) and straddle trucks with tiltable masts, as specified in ISO 22915?3; c) pallet stackers with tiltable masts, as specified in ISO 22915-4; d) bidirectional and multidirectional (retractable mast or forks) trucks with tiltable masts, as specified in ISO 22915?7; e) rough-terrain trucks with tiltable masts, as specified in ISO 22915-13; f) counterbalanced trucks fitted with articulated steering with tiltable masts, as specified in ISO 22915-15.
Chariots de manutention — Vérification de la stabilité — Partie 8: Essai de stabilité supplémentaire pour les chariots travaillant dans des conditions de gerbage spéciales avec le mât incliné en avant et la charge élevée
La série ISO 22915 traite de la sécurité des chariots de manutention tels que définis dans l'ISO 5053‑1, concernant leur stabilité et la vérification de cette stabilité. Pour les besoins de la série ISO 22915, les chariots de manutention sont des véhicules sur roues, automoteurs ou à propulsion manuelle, à l'exception de ceux se déplaçant sur rail. Ils sont soit avec conducteur, soit sans conducteur et sont conçus pour transporter, tracter, pousser, soulever, gerber ou stocker en rayonnages. Le présent document spécifie un essai supplémentaire pour la vérification de la stabilité d'un chariot gerbant avec le mât incliné vers l'avant et la charge en position élevée. Il est applicable aux types de chariots suivants: a) chariots en porte-à-faux à mâts inclinables, tels que spécifiés dans l'ISO 22915‑2; b) chariots retract (à mât ou à fourches rétractables) et à fourche entre longerons à mats inclinables, tels que spécifiés dans l'ISO 22915‑3; c) chariots à fourche recouvrante à mats inclinables, tels que spécifiés dans l'ISO 22915‑4; d) chariots bidirectionnels et multidirectionnels (à mât ou à fourches rétractables) à mats inclinables, tels que spécifiés dans l'ISO 22915‑7; e) chariots tout terrain à mâts inclinables, tels que spécifiés dans l'ISO 22915‑13; f) chariots en porte-à-faux équipés d'une direction articulée à mâts inclinables, tels que spécifiés dans l'ISO 22915‑15.

Overview
ISO/FDIS 22915-8 is an international standard published by ISO that focuses on the verification of stability for industrial trucks operating under specific challenging conditions. This standard addresses an additional stability test tailored for trucks when stacking with the mast tilted forward and the load elevated. Industrial trucks, as defined in this context, are self-propelled or pedestrian-propelled wheeled vehicles designed for various material handling tasks such as lifting, stacking, towing, and pushing.
This part of the ISO 22915 series is essential for ensuring the safe operation of trucks under the special condition where stability risks are increased due to the forward tilt of the mast combined with an elevated load. It is applicable to a range of truck types fitted with tiltable masts, thereby contributing to enhanced safety protocols and compliance in industrial operations.
Key Topics
Scope of Stability Verification
ISO/FDIS 22915-8 specifies an additional test beyond general stability requirements, addressing the unique scenario of stacking with the mast tilted forward and load elevated.Applicable Truck Types
This standard covers various industrial trucks as defined in ISO 5053-1, including but not limited to:- Counterbalanced lift trucks
- Reach and straddle trucks
- Pallet-stacking trucks
- Side-loading trucks
- Multi-directional lift trucks
- Rough-terrain trucks
- Articulated counterbalance lift trucks
Test Conditions and Procedures
Detailed provisions include truck positioning on a tilt table and mast alignment in test setups. The document outlines conditions to replicate real-world challenges faced during stacking operations.Integration with Other ISO Standards
This document references and complements other parts of the ISO 22915 series (e.g., ISO 22915-2, -3, -4, -7, -13, and -15) which specify stability verification for different truck types and configurations.Normative References
The standard incorporates terminology and safety requirements aligned with ISO 5053-1 (vocabulary for industrial trucks) and ISO 3691-1 (safety requirements for self-propelled industrial trucks).
Applications
Workplace Safety Assurance
Organizations operating industrial trucks in warehouses, manufacturing plants, and logistics centers can use ISO/FDIS 22915-8 to verify and enhance the stability of trucks during complex stacking operations, minimizing the risk of accidents.Manufacturing and Design Validation
Truck manufacturers employ these stability tests during design and production to comply with international safety standards, ensuring their products can safely handle loads in elevated stacking scenarios.Regulatory Compliance
Compliance with ISO 22915-8 supports adherence to occupational health and safety regulations by demonstrating that industrial trucks have undergone rigorous stability assessments.Operator Training and Risk Management
The standard provides a basis for developing training materials highlighting special stability considerations when operating trucks with tiltable masts in stacking applications.
