Conical dynamic test is to use a certain hammering kinetic energy to penetrate a certain size of probe into the soil, according to the number of hammering into the soil - a certain depth to determine the stratum characteristics and load-bearing capacity and other parameters.
WKZ conical dynamic detector is slippery pin type. It consists of heavy hammer, guide rod (hammer rod or piercing rod), hammer base, lifter, contact probe and sling. It can be divided into three types: light type, heavy type and super heavy type.

WKZ动探类型和主要参数表
类型		轻型	重型	超重型
落锤	重锤质量( kg )	10±0.2	63.5±0.5	120±1.0
落锤	落距(cm)	50±2	76±2	100±2
触探头	直径(mm)	40	74	74
	截面积( cm2)	13	43	43
	圆锥角(。)	60	60	60
触探杆	直径(mm)	25	42/50	50
触探杆	每米质量(kg )	＜3	＜8	＜12

The heavy hammer falls off freely with the penetrating rod and is in a state of free falling.
It has a light and reliable down-grab and up-release slide pin lifter to ensure accurate drop distance.
Specially made short and flexible spring hammer rod, which is flexible and convenient to use.
Set up security organs such as hammer hook, which are safe and reliable during the test.
Multi-purpose hammer: hammer touch probe, standard penetrator, soil collector. >WGZ standard penetration tester

Standard penetration test uses 63.5 kg automatic drop hammer with a drop distance of 76 cm. The standard penetrator's bottom height is first hit 15 cm deep, and then the number of hammers (standard penetration number) which continue to hit 30 cm is recorded. The test method for evaluating the properties of foundation soil layer is based on the number of hammers.
The hardness of WGZ-1 standard penetrator is above HRC 40, and the surface roughness is less than 6.3um.
Specification size: D51 x 35 x 700 mm (outer diameter x inner diameter x length) meets the relevant national standards.
