Overview

ISO 10245-5:1995 - "Cranes - Limiting and indicating devices - Part 5: Overhead travelling and portal bridge cranes" specifies safety and performance requirements for devices that limit or indicate loads, motions and environmental/operational conditions of bridge and gantry (portal) cranes. It complements the general requirements in ISO 10245-1 and focuses on the unique hazards and control needs of overhead travelling and portal bridge cranes.

Key topics and technical requirements

• Scope and applicability: Requirements apply to limiting and indicating devices used on bridges and gantry cranes for loads, motions, performance and environment.
• Rated capacity limiter:
  • Required when there is a hazard of overturning or when unpredictable loads may cause overloading.
  • Must allow upward acceleration of rated load and be adjustable/blocked for test procedures.
  • May include measures to prevent sensing transient dynamic loads.
  • Settings and definitions reference gross load (QGL), rated capacity limit setting (QL) and design mean acceleration; amplifying factors are referenced to ISO 8686-1.
• Rated capacity indicator:
  • Required when crane capacity depends on load position or where indicator improves safety and control.
  • Should provide continuous visual and/or acoustic warnings; typical warning actuation is at about 90–95% of rated capacity.
• Motion limiters:
  • Any motion with design restrictions must have a motion limiter; common devices include cut‑out limit switches, slow‑down devices, back‑up limits, buffers and end stops.
  • Selection guidance is provided for hoisting, lowering, travelling, traversing and slewing motions.
  • Design must limit maximum acceleration experienced by the crane operator to less than 4 m/s².
  • Collisions (including potential collision of two cranes) and structural accelerations induced by limiters must be considered.
• Performance and indicating devices: Performance limiters and motion/performance indicators are required based on application needs to support control and safety; tandem hoisting arrangements must ensure limiters override motions that produce overloads.

Applications and users

ISO 10245-5 is intended for:

• Crane manufacturers and hoist/winch suppliers (design and factory setting of limiters/indicators)
• Plant and lifting equipment designers integrating bridge/gantry crane controls
• Safety engineers, maintenance teams and inspectors (installation, testing, commissioning and periodic checks)
• Asset owners and procurement specialists specifying safety devices and compliance for overhead travelling and portal bridge cranes

Practical uses include specifying rated capacity limiters and indicators, selecting motion‑limiting hardware, defining alarm setpoints, and ensuring safe tandem hoisting and positional‑dependent capacities.

Related standards

• ISO 10245-1: General requirements for limiting and indicating devices
• ISO 8686-1: Design principles for loads and load combinations (referenced for load amplification factors)
• ISO 4306-1: Cranes - Vocabulary (general terms)

Keywords: ISO 10245-5, cranes, overhead travelling cranes, portal bridge cranes, limiting and indicating devices, rated capacity limiter, motion limiter, rated capacity indicator, crane safety.
