Passenger Hoist Overload Protection Device for Construction Hoists

Passenger Hoist Overload Protection Device for Construction Hoists

A passenger hoist overload protection device is an important component of a construction hoist load monitoring system. It helps detect excessive loads in the hoist cage and supports safer lifting operations on construction sites.

The Overload for Passenger Hoist supplied by SYM is listed for GJJ and BAODA equipment. It uses a pressure sensor to measure the load applied to the hoist cage and converts the measured force into an electrical signal for the load limiting device.

How Does a Passenger Hoist Overload Sensor Work?

The pressure sensor is installed beneath the construction hoist cage with a supporting steel plate. As the load changes, the sensor detects the resulting force and sends an electrical signal through the transmission cable.

The load limiting device processes the signal and compares the measured load with the preset limit. When the load reaches or exceeds the configured value, the corresponding control output can activate the hoist control system to restrict operation according to the system design.

Key Functions of Construction Hoist Overload Protection

Load Monitoring: Detects changes in the load carried by the hoist cage.

Electrical Signal Transmission: Sends load-related signals to the limiting device for processing.

Overload Response: Supports the control system in responding when the preset load limit is reached or exceeded.

Equipment Maintenance: Provides a component for replacing or maintaining the overload protection system on compatible construction hoists.

Applications

This overload protection component is intended for passenger hoists and construction hoists requiring load monitoring and overload control.

Before purchasing, check the hoist model, sensor configuration, installation dimensions and electrical connection requirements to ensure compatibility with the existing system.

Frequently Asked Questions

Q1: What is the function of a passenger hoist overload protection device?

It monitors the load carried by the hoist cage and helps the control system respond when the configured load limit is reached or exceeded.

Q2: How does the overload sensor measure the load?

The pressure sensor detects the force applied through the supporting structure and converts it into an electrical signal for processing by the load limiting device.

Q3: Which construction hoists is this product suitable for?

GJJ and Other Brands. Confirm the exact hoist model and sensor specifications before ordering.

Q4: What should be checked during maintenance?

Inspect the sensor installation, supporting plate, transmission cables and electrical connections. Functional testing and calibration should follow the equipment manufacturer's instructions and be performed by qualified personnel.

Q5: What information is needed to request a quotation?

Provide the hoist brand, model, required quantity and available part number or photos of the existing component. These details help confirm the correct replacement.
