Construction crane Safety Evaluation System Overview

In order to carry out scientific and accurate construction crane security rating, need to propose different devices risk assessment, monitoring and early warning accident prevention measures,manual block the establishment of construction crane safety evaluation system.
Construction crane safety evaluation system as follows:
Construction crane safety evaluation of all aspects of the device to which the design, manufacture, installation, use, alteration, repair, use, scrapped every stage. Safety Safety Assessment is divided into pre-evaluation, safety acceptance evaluation, safety evaluation and special safety evaluation four categories.
(A) safety pre-assessment is in construction crane design, production carried out before, the project aims to analyze and predict the presence of dangerous and harmful factors, the type and extent reasonably practicable,lift hoist the safety of proposed technical design and safety management advice. Safety purpose of the evaluation is to identify the pre-construction crane manufacturing process inherent hazards or potential hazards and harmful factors; been selected by the evaluation method to evaluate the risk of harm arising from the extent of the main conditions; relating to safety and quality control regulations, standards, and combined with the actual situation exists for the construction crane hazardous and harmful factors put forward corresponding countermeasures, measures;
      (2) evaluation of safety and acceptance in the construction crane manufacturing factory or installed and put into use before the end of the evaluation, designed by the construction crane operating conditions of testing, inspection, find the device officially running the risk may exist, harmful factors put forward reasonable and feasible reform program of security technologies and security management measures;
(3) safety evaluation for construction crane (eg: electric hoists, chain hoists) security status of the safety evaluation, designed to find the existence of dangerous and harmful factors that determine the extent to propose reasonable and feasible safety countermeasures and suggestions. Include the following: a comprehensive collection of information needed for the evaluation, the use of appropriate methods for safety assessment hazard identification, the security status given quantization parameter values; may cause significant consequences for accidents, with the corresponding mathematical model for accident simulation, forecasting the impact of extreme circumstances the scope of the accident the maximum loss, and the probability of an accident; the discovery of the hidden dangers, according to quantify the security status of parameter values, the priority of the rectification sort;
(4) special safety assessment is based on the requirements of government supervision and management department carried out, for security issues of special safety analysis and evaluation, such as registering at construction crane equipment evaluation and rectification when lifting device evaluation. Special safety evaluation generally is for a certain type of construction crane or safety devices exist dangerous and harmful factors of safety evaluation,load chain the purpose is to find the existence of dangerous and harmful factors that determine the extent of proposed safety measures and reasonable and feasible recommendations.
Construction crane safety evaluation reads as follows:
The basic contents of the safety assessment, including hazard identification and risk assessment in two parts. Hazard identification, including hazard identification and calculation of risk-free rate; risk evaluation, including identification of indicators and risk control. Safety assessment through risk identification and risk assessment. Objectively describe the degree of risk construction crane, guiding people to advance to take appropriate measures to reduce the risk of construction crane.
