The Crane Sentry® Wire Rope Hoist Side Pull Detection is capable of detecting excessive side pull on a wire rope hoist and alerting the operator of the condition or disabling functions.

Reasons For Side Pull Detection

1. Damage to Hoist

Most standard hoists are not engineered to handle side pull load

2. Personnel Injury

Injury is possible if the load shifts once it is lifted from its resting place on the floor or a staging fixture

3. Damage to Equipment

Damage to nearby equipment is possible once the load shifts after it is lifted

Why Crane Sentry® Wire Rope Hoist Side Pull Detection?

• Usage of hoists for lifting loads in industrial applications has inherent risk, requiring the need for safety precautions
  • If a load is not lifted directly vertical and is permitted to side load a hoist, referred to as “side pulling”
  • Side pulling can damage to the hoist, injury to personnel, and/or damage to nearby equipment
  • Detection of potential side pull conditions can be tied into hoist controls to not permit a lift under this condition
• Side pulling a hoist is not permitted by OSHA regulations under most conditions
• Many hoists installed in industry do not have any form of side pull protection installed

Our Solution

• Solid state side pull detection system consists of an
   assembly that mounts to the wire rope
• Mount assembly to the dead end (fixed end) or
   around the equalizer sheave
• Install on single or double reeved hoists
• Adapts to a range of wire rope diameters
• Controls mount to the hoist or trolley and provide an
   intuitive menu driven interface
• One button zero feature
• Set limits, timing, hysteresis
• Built in error logging (time and date); last 5 event

Includes
Controller P/N 001017-03

• Connects to (1) 2 axis sensor
• M12 quick connect cable
• Simple and intuitive menu driven controls show set point and live readings
• Set limits
• Manual zero feature;
• Set hysteresis, error time out, and delay
• Built in error logging (time and date); last 5 events
• 2) Mechanical NO/NC relay outputs (8A); behavior is user configurable
• X/Y omnidirectional axis limit (upper/lower)
• X/Y omnidirectional  axis auxiliary limit (upper/lower)
• 110 VAC/220 VAC single phase power required; control box self-powers the connected sensors
• Polycarbonate wall mount sealed enclosure mounts on hoist
