In mountain construction, terraced construction sites or temporary slope scenarios, "equipment slipping, weak climbing, and rollover risk" are the "persistent problems" of construction site off-road forklifts. Ordinary forklifts "fail" when encountering slopes above 30°: uneven power distribution causes rear wheels to slip, and the differential "wastes" power when one side is suspended, which may delay the construction period at best or cause rollover accidents at worst. However, Hengwang construction site off-road forklift, relying on two "climbing king" designs of "slope sensing + differential locking", completely solves the steep slope handling dilemma — this article disassembles the core technologies, with measured data of maximum climbing angle, to help you choose the right equipment!
I. Two core technologies of "climbing king": Turn steep slopes into "smooth roads"
1.Slope sensing system: Automatically adjust power to prevent slipping
Traditional forklifts often have rear wheels slip on slopes due to insufficient or uneven power. Hengwang construction site off-road forklift is equipped with an intelligent slope sensing system: real-time monitoring of slope through an inclination sensor (accuracy ±2°), automatically adjusting engine power and hydraulic output — increasing power output when going uphill to compensate for gravity resistance; reducing speed when going downhill and intelligently distributing braking force to avoid "sudden forward movement". This design allows the equipment to climb stably on temporary slopes above 30°, with no slipping throughout.
2.Differential locking function: One-sided wheel slipping? Lock power in 0.3 seconds!
When the slope road is uneven (such as gravel, mud pits) causing one-sided wheels to be suspended or slip, the differential of ordinary forklifts will "waste" power on the idle wheels. Hengwang construction site off-road forklift is equipped with mechanical/electronic dual differential locks: when one-sided wheel slipping is detected, the differential is locked within 0.3 seconds, transmitting 100% power to the wheels with grip. In actual tests, even if one-sided wheel is suspended on a 35° steep slope, the equipment can still climb steadily, completely avoiding the embarrassment of "idle slipping".
II. Recommended "climbing king" models for different slope scenarios
Hengwang construction site off-road forklift has launched a variety of "customized climbing models" for different steep slope needs, with maximum climbing angles covering 30°-40°, suitable for complex scenarios such as mountains, terraces, and temporary slopes:
HW-30A: Maximum climbing angle 30°, suitable for mountain temporary slopes or terrace handling. Standard with single-stage differential lock + slope sensing system, can operate stably on 30° slopes with a load of 3 tons, suitable for daily building material transfer.
HWC-40A: Maximum climbing angle 35°, specialized in material transfer in mining areas/steep construction sites. Upgraded with two-stage differential lock + intelligent slope adjustment, can climb at a constant speed on 35° steep slopes with a load of 4 tons, 30% more efficient than ordinary forklifts.
HWCY-50A: Maximum climbing angle 40°, specially designed for rock areas/ultra-steep step construction. Equipped with heavy-duty differential lock + 265 dual high-low speed torque converter, can handle 40° steep slopes with a load of 5 tons like walking on flat ground, making it a "handling tool" for mines and cliff construction sites.
III. International customer testimony: "Chinese power" on 40° ice slopes
Interlaken Mountain Engineering Company, Switzerland
"We were laying cable car foundations on the Jungfrau, with an average construction site slope of 35°+ ice-rock roads. Traditional forklifts handled only 15 tons per day until we introduced Hengwang HWC-40Aconstruction site off-road forklift — it was stable as flat ground on 40° ice slopes, completing 50 tons of steel transportation daily, saving €25,000 in labor costs in half a year!"
—— Hans Müller, Equipment Supervisor
IV. Three strengths that make Hengwang "climbing king" more durable
Bridge reinforcement of Hengwang construction site off-road forklift: Adopting cast steel integral bridge (torsional strength increased by 40%), no deformation under steep slope stress, no "failure" during long-term operation;
Tire adaptation: Standard 20.5R25 anti-slip solid tires (deep surface patterns + high friction coefficient), no slipping on mud pits and gravel roads, service life twice that of ordinary tires;
After-sales guarantee: 32 spare parts warehouses worldwide, maintenance parts delivered within 48 hours, no worries about steep slope operations.
For steep slope/step handling, choosing the wrong equipment will "affect" both construction period and safety. Hengwang construction site off-road forklift, with two "climbing king" designs of "slope sensing + differential locking" and super climbing capacity of 30°-40°, has become a "handling tool" for mountain, terrace, and temporary slope scenarios.
