Overview of Safety Features for Pump Trucks
Release time:
2025-05-22
Data source:
(1) Lifting weight indicator (angle plate, also called weight limiter) The angle indicator of the boom root mounted on the pump truck close to the driving position will change with the elevation angle of the boom. Check the angle between the concrete pump truck boom and the ground, and know the elevation angles of the pump truck boom at different positions. According to the crane's performance table and performance curve, the amplitude value, lifting weight, lifting height and other reference values at a certain elevation angle can be known.
(1) Lifting weight indicator (angle plate, also called weight limiter)
The angle indicator of the boom root mounted on the pump truck close to the driving position will change with the elevation angle of the boom. Check the angle between the concrete pump truck boom and the ground, and know the elevation angles of the pump truck boom at different positions. According to the crane's performance table and performance curve, the amplitude value, lifting weight, lifting height and other reference values at a certain elevation angle can be known.
(2) Over-winding limiter (also called super-high limiter)
A safety device installed on the pulley block at the end of the boom of the pump trucks to limit the lifting height of the hook head to prevent winding accidents. It ensures that when the hook is lifted to the limit position, it can automatically send out an alarm signal or cut off the power source to stop lifting to prevent over-winding.
(3) Torque limiter
The torque limiter is a safety device that automatically cuts off the lifting or luffing power source when the load torque reaches the rated lifting torque, and sends out a prohibitive alarm signal. It is a limiter to prevent crane instability caused by overload.
(4) Anti-arm rod backward device and anti-back rod bracket
The anti-boom backward device and the anti-back lever bracket are safety devices that no longer lift when the boom is raised to the maximum rated elevation angle. It prevents the boom from tilting backward when the boom is too large.

A High-Performance Powerhouse for Faster Concrete Pouring: JIUHE Trailer Concrete Pumps
With over two decades of expertise in pumping equipment, Jiuhe Heavy Industry leverages cutting-edge technology to refine a comprehensive range of concrete pumps.
Operational Details for Trailer Type Concrete Conveying Pumps
Based on years of R&D and manufacturing experience, Jiuhe Heavy Industry identifies the following key operational details for small concrete delivery pumps:
JIUHE Truck-mounted concrete pump
With the rapid development of the construction industry, methods for transporting concrete are constantly evolving. In the past, stationary concrete pumps (or "trailer concrete pumps") were the primary method, but truck-mounted concrete pumps ( also called "concrete line pump" )have now gradually become the mainstream choice.
Precautions for the Use of Trailer Mounted Concrete Pumps
The trailer-mounted concrete pump is a very common piece of construction equipment; favored by contractors for its compact size, ease of transport, and cost-effectiveness.
What causes the S-pipe of a concrete pump to not swing properly?
The S-tube is a crucial component of a concrete boom pump. Its primary function is to connect the boom's piping to the concrete delivery cylinder, enabling continuous concrete pumping.
